Top-10-tips-for-living-more-sustainably-in-2010





Ten tips for living more sustainably in 2010
A new decade & almost the beginning of a new year - is the time many people try to live differently.

For some, that change means living a more sustainable lifestyle. Sustainability, once merely a buzz word, is fast becoming the way to live consciously.From reducing your water usage to buying organic, here are 10 easy ways to make 2010 your year of sustainable living:

1. Use water more efficiently: Water is a limited resource and limiting it within your home is a cornerstone of sustainability. Rain butts, largely unheard of even a decade ago, are becoming a popular way to collect and reuse rainwater (Grey water) for purposes like gardening. Meanwhile, conserving water in the home by taking shorter showers or even fixing a leaking tap also can make a difference at a time when many communities are experiencing water shortages or are expressing concerns about water overuse.

2. Compost: Turning over leaves by way of a new compost garden is one way to live a more sustainable lifestyle. A compost heap is a simple, way to collect garden waste, like leaves and grass cuttings, and kitchen scraps such as raw vegetable peelings and tea leaves, and return them to the ground as organic matter.

3. Seek Eco-friendly packaging: To better fill that compost heap, alter shopping habits to look for products with compostable (Biodegradable) packaging.

4. Buy local & organic: Many farmers and, increasingly, food manufacturers, are offering foods and drinks made using sustainable practices. It could be a farmers market tomato, a local dairy's milk, an organic snack food, or any number of natural or organic items. The bottom line is that natural, organic and locally produced foods provide both sustenance and sustainability.

5. Go to seed: Take the locally grown movement a step further - like in your own garden or patio. One afternoon spent planting seeds or small plants can yield plenty of rewards a few weeks or months later, in the form of fresh, inexpensive and organic vegetables and fruits. You don't need a large plot of land, in fact, to start a small garden.

6. Ride out the trend: Sustain your own energy level by choosing to ride a bike or walk to a destination that isn't all that far away. Add a basket to a bike or take along a rucksack to bring something back home.

7. Re-recycle: Recycling is nothing new and most people have been recycling in some form for years. But recycling can be taken to another level, going beyond obvious and traditionally recycled items like drinks cans or newspaper to the smallest of waste materials, from plastic straws to the paper straw wrapper. Why not recycle clothing as well, by donating clothes and buying used clothes?

8. Plug in: Learn how to operate appliances more efficiently. For example, use cold water in the washing machine: clothes will still be cleaned, without the use of heated water. Turn off appliances when not in use, whether it's the television, computer or radio. Better yet, completely unplug. Many electronics and battery chargers continue to draw a small amount of power even when they are in standby. Instead, switch off at the socket outlet to cut power completely when not in use.

9. Lighten up: Use energy efficient lighting and lamps when possible and turn off lights when not in a room. That will reduce energy use and the family outgoing budget.

10. Get involved: As the sustainability movement gains momentum among the public, there are more opportunities to join in. Local communities, schools and organizations often have green committees, and there is a plethora of national and grassroots organizations geared around earth-friendly living that appreciate new volunteers or members.

NanoSolar-Printed-Solar-Cells-Cheapest-In-The-World

NanoSolar Inc - Printing Solar Film

For a number of years I have been watching the development of a Californian based company NanoSolar Inc (Nano Solar Inc). My interest started when I realised that the cost of solar cells were so high it would never become viable for every rooftop to have a solar panel array. I have thought of various ways and means to bring cheap renewable energy to the masses but always strayed back to Solar PV cells.

What they have come up with is a way to print (Screen Print) Solar Substrate straight onto a thin foil material which means no more expensive silicon wafer based panels which are thick, heavy and expensive to produce. The new technology opens up a whole new dimension for end users.

Imagine an all electric vehicle with a Solar PV shell? How about solar slates that are cheaper than roofing tiles? A parking lot for electric vehicles with a solar roof? The new uses are endless!

NanoSolar Inc are fully booked with orders for the next 2 years (Correct as of July 2009) The demand is huge, they are gearing up for more production capacity already!

I would love to see a time when renewable energy can directly compete with fossil derived fuels (Coal, Oil & Gas) I think the Printed Solar Panels are a step in the right direction.

Semiconductor Printing

Printing is by far the simplest, highest-yield, and most capital-efficient technique for depositing thin films. Printing is extremely fast; the equipment involved is easy to use and maintain; and it works in plain air (no vacuum chamber required).

Another key advantage of a printable CIGS ink is that one can print it just where one wants it to be, achieving high materials utilization of the semiconductor material.

Printing is much simpler and more robust than vacuum deposition techniques such as sputtering or evaporation which have conventionally been used to fabricate thin-film solar cells; the process cost of vacuum techniques is so high that the result is not an inexpensive cell relative to the per-square-meter economics that the solar industry requires.

Domestic-Wind-Turbines



There are 2 main types of wind turbine that are suitable for use with a domestic house.

1. Grid-Tied Wind Turbine:

Grid-Tied, simply put, means your wind turbine is connected in line with your national grid electricity supply. When you are using less electricity than your wind turbine is producing then the excess power is pushed past your electricity meter and back into the nation grid. This enables your meter to run backwards and reduce your bill you have to pay to your electricity supplier.
The disadvantage with a grid tied wind turbine is that in the event of your electricity supply shutting down (Power Cut) then the wind turbine supply shuts down also meaning you will have no electricity supply until the grid supply is restored. This is a safety feature to prevent your supply back feeding the national grid in the event of a power cut.

2. Isolated Wind Turbine Feeding Batteries:

A system that supplies batteries is not as efficient as a grid tied wind turbine due to the losses in storing electricity in batteries instead of directly feeding the national grid but the plus side is that the electricity you produce can be stored for later use.
You require a wind turbine designed to charge your battery bank. You also require suitable, maintenance free batteries for power storage, if you require domestic AC (Alternating Current) power then you will need an inverter to convert the DC (Direct Current) back to 230V AC that can be used with mains powered domestic appliances.

DIY-Geothermal-Ground-Source-Heat-Pump-By-Rick-Faszold





Rick Faszold decided to take on his very own geothermal ground source heat pump installation, A DIY project larger than anything he had previously attempted in his 20 years of marriage. His main objective was to complete the entire Geothermal ground source heat pump domestic system within a budget of $10,000.00 USD.

Considering he was in receipt of quotations in excess of $25,000.00 USD he has certainly set his targets high!

Richard Faszold's Geothermal DIY Website

Why is Richard Faszold taking on such a huge challenge? Below are his very own words....

The Short Answer - I want to save money, help the environment and have a project/hobby that I could work on at home.
The longer answer is….. a few years ago, I began to look at the solar power as way to reduce our energy bills. Our propane bill was going up (same usage), our local electric utility went up a smidge and we endured a few “longish” power outages. (Looking back over 4 years, our propane bill went up 40%!.)

I thought solar would be a way to pay one more time for power and be done with it forever. No more bills, power outages and wasted refrigerator items. As I looked down the road to retirement, it occurred to me that our current (2007) energy bill of $4,400, would probably double by the time I retired. (We live in a 2,100 sq/ft home.) Taking an estimate of $8,800 annually for energy costs at retirement, ten years of energy cost into retirement would be tough to deal with. Perhaps this amount is too much or not enough for you, this is merely a guess as to what could be. We felt that trying to compensate for this bill by saving more for retirement would have too much of a negative impact on our budget.

So, I started looking for ways to deal with this issue.I started with solar first. It seemed simple and it would be able to do everything we needed it to do. Just purchase a bunch of panels and no more electrical bills. Move to electric heating and a nice generator (for rainy days) and all is well. Unfortunately, part of the solar calculation is Peak Kilowatt Hours or what your peak energy demands are. From there you size the system to meet your peak needs. Along the way you increase capacity to compensate for winter (less hours of sun) and lost efficiencies. Meeting our peak needs would have costs us about $35,000 upfront. (2006 costs) This was far too expensive. The solar folks know that it is important to weather proof as much as possible, buy different appliances, and make some lifestyle changes in order to reduce the cost of a system. This is wise; but, not workable for our family. Again, it would be a budget issue or a lifestyle problem that we faced.As of July of 2007, solar was really ramping up to the point where there were world wide shortages of photovoltaic panels and prices increases.

Various countries have committed to utilizing this power and manufacturing facilities just did not see this type of demand coming. It will be well into 2009 before enough manufacturing comes online to meet demand and reduce prices. Also, there are some exciting new technologies that promise to increase the overall conversion efficiency by two fold.What I was really trying to do with solar was to never pay another utility bill again. Since solar was not working out financially, I took a harder look at our energy bill and broke it down into a few categories to see what I was really dealing with. I realized that our heating bill was roughly $2,200 annually (propane and going up very quickly) and our summer cooling bill was over $1,000, thus our heating and cooling alone were about 75% of our energy needs. I felt that if I could find a cost effective way to take care of heating and cooling, then I might be able to go back to solar.

In searching through the Internet, I stumbled upon Geothermal.Geothermal, “seemed” simple and cheap. (It is neither.) I jumped at wanting to get a geo system until I started getting bids that were north of $25,000. $25,000 is still too expensive plop down for 75% of our energy needs. Yes, it “seemed” to pay for itself over time (Nine year ROI); but, it really didn’t financially do everything I hoped it would do. It was cheaper than solar; but, not that much cheaper. So, this was very depressing.

I thought I would be stuck paying utility companies forever.As I was surfing around, I found a gentleman who said he did his geo system by himself AND did it for under $7,000! (That was in the later 90’s.) $7,000 is definitely budgetable and has a very nice ROI considering a current $3,200 a year heating and cooling bill. An interesting note is that a 1998 study by the EPA indicates that for every $1 reduction in energy cost, the value of the home rises by $20. It would be nice if they would update this study a bit in light of current energy costs and the sub-prime market melt down. This is 1998 dollars AND since the stock market is going nuts due to the sub-prime meltdown, I have no idea of what this means.

Note: As of February 2009, we decided to re-fi our home. Our appraiser gave NO added value to the house due to the Geo system. This began quite a while of searching and talking to folks about geo in order to get to a point where I felt comfortable doing this myself. Thus, I began my own geo project. The only thing that I can offer to you is… ask a LOT of questions and know that if you do this, you will still miss something… Hopefully, it will not be big.

Money-Saving-Tips-On-Building-An-Off-Grid-Homestead




TIP #1: If you buy building materials in small quantity you will pay full retail price. Instead figure out exactly what materials you will need. Include everything from screws to appliances. Make your material list look professional and take it to any large construction supplier like home depot or lowes. Do not talk to a clerk but go straight to the contractor desk or speak to a manager and tell them you are building your own home and would like the contractor discount for buying all the materials from them.

Most building supply stores will give you anywhere from 5% to 15% discount if you buy all material at one time. They may even throw in free delivery if you live within a certain mileage.

If you have to buy in small quantities go to the mom and pop building suppliers with your list and ask the manager for a discount if you buy all your materials from them over time. You will still usually get a discount and be supporting your local dealers.

TIP #2: If you are using solar (I hope) try to buy your panels in bulk for a big discount. Most panel suppliers will give 30% or more for bulk sales of ten panels or more and a smaller discount if you buy more than one. Talk to the owner if possible as salesman rarely have power to discount. Get your power controller and necessary wiring and even batteries from the dealer and get an even bigger discount!

TIP #3: Recycle whenever possible. Good used Doors and windows can be had for free or cheap from most window installers. Get double pane and insulated doors for exterior. They may need painting and might be different sizes but the savings is worth a little extra work.

Good used appliances can be had for free or cheap. Check out your local freecycle website, garage sale, city dump, or look for homes being remodled and make an offer. Sinks, toilets, cabinets, tubs, showers are always being thrown away so do some scrounging and don't waste money on new ones.

New propane appliances can be expensive but if you have or can buy an old rv cheap salvage all your propane appliances to outfit your home.

TIP #4: Design your home for efficiency. Consider how big of a home you really need. Smaller homes are cheaper to build, cheaper to heat and cool, easier to clean and lower in property taxes. Because people are looking for smaller efficient homes they also raise in property value faster than big inefficient homes.

TIP #5: Use the sun and passive energy. Situate you house to take advantage of the sun for winter heating and solar panels. Plant trees for natural summer cooling. Use overhangs to block summer sun and porches for cool resting spots. Passive air turbines instead of expensive air conditioning.

TIP #6: Go solar! There is a fed rebate of 30% for any size solar electric system installed by a professional installer. You can get this rebate even if you do the work yourself if you will contact an installer and ask them to design your system and oversee your work. get them to sign off on the work as being installed professionally and you can get the rebate. Many installers will do this and I do it all the time for clients. If you buy your equipment from them they can get you a bigger discount and they will give you valuable advice for designing the right size system for your needs. It may be worth a few hundred dollars to have their professional experience and you will save a lot in the rebate and having a correctly designed system.

TIP #7: Do the work yourself! Even if you have no building experience you can save a lot by having a knowledgeable builder use you for labor on your own home. Take a construction class or volunteer with a habitats for humanity project or your neighbors construction to learn the skill you need. Home construction is not difficult and most people that have basic construction knowledge can do it themselves or with a little guidance from a knowledgeable builder.

Lister-CS-Stationar-Engines-Power-Generation




Lister CS (Cold Start) stationary engines, or their Indian clones referred to as Listeroid stationary engines, are one of the most versatile long running stationary engines the world had ever seen. They are more than capable of running on almost any viscous oil including Peanut oil, Canola oil, Vegetable Oil, filtered waste vegetable oil, filtered waste motor oil, diesel oil, crude oil, gearbox oil, sunflower oil and many more. There are a number of enthusiasts out there who are experimenting with running them on a mixture of Fuel Oil and Wood Gas Fumes.
The Lister CS range of engines are Slow RPM (650RPM to 700RPM) 4 stroke single cylinder stationary engines. They are over engineered and have been known to run unattended for in excess of 200,000 hours.
They use the simplest of technology which lends them to less maintenance and breakdowns.
Below is a list of interesting websites that document their progress on Using the Lister CS (Listeroid) stationary engines to provide heating and power for domestic dwellings / Low impact homes.
Using a Lister CS / SOM (Start-O-Matic) Stationary engine to produce both power and heating is commonly referred to as a CHP (Combined Heat Power) CHAP (Combined Heat And Power) or MCHP (Micro Combined Heat And Power)
The Diesel Engine Basics
A diesel engine is an internal combustion engine which operates using the diesel cycle (named after Dr. Rudolph Diesel). Diesel engines have the highest thermal efficiency[citation needed] compared to any internal or external combustion engine.The defining feature of the diesel engine is the use of compression ignition to burn the fuel, which is injected into the combustion chamber during the final stage of compression. This is in contrast to a petrol (gasoline) engine or gas engine, which uses the Otto cycle, in which a fuel/air mixture is ignited by a spark plug.
Diesel engines are manufactured in two stroke and four stroke versions. They were originally used as a more efficient replacement for stationary steam engines. Since the 1910s they have been used in submarines and ships. Use in locomotives, large trucks and electric generating plants followed later. In the 1930s, they slowly began to be used in a few automobiles. Since the 1970s, the use of diesel engines in larger on-road and off-road vehicles in the USA increased. As of 2007, about 50 percent of all new car sales in Europe are diesel.

Straw-Bail-Homes-Carol-Atkinson-Howden

Straw Bales are the Way Forward in Construction

A study to research the potential for using straw in construction has led to a coveted Nuffield Farming Scholarship for a woman who firmly believes building with straw bales is the way forward.

Carol with Yorkshire Agricultural Society Chief Executive Nigel Pulling in front of one of Carol's straw bale buildings.

straw bale building










Carol Atkinson, who farms with her husband at Howden near Goole, already runs the Straw Bale Cabin, a one-bedroom holiday cottage. A second, larger cottage is currently under construction and is expected to be completed by May this year.

She is sponsored by the Yorkshire Agricultural Society following her successful application to the Nuffield Farming Scholarships Trust. The Society, best known for organising the annual Great Yorkshire Show, is committed to promoting and assisting the developments in farming.

Nigel Pulling, the Society’s Chief Executive said Carol’s study was not only interesting but could lead to new business opportunities for farmers.

“Agriculture faces increasing challenges and her study should prove extremely valuable in highlighting a possible growth area. Straw bale building has the potential to provide farmers with a new income stream, as well as being good for the environment.”

Nuffield Farming Scholarships are prestigious agricultural awards recognised around the globe. They promote leadership and the implementation of innovative agricultural practices through worldwide study.

Carol will travel to the United States, Canada and Europe to look at how straw bales are used in construction and investigate how the idea could be more widely used in Britain.

“I’m passionate about the potential for building with straw,” explained Carol. “There are benefits for farmers too, such as adding value to their crops, and wider benefits for the environment. It also means there could be more low-cost rural housing, it would boost rural skills and there would be a natural, non-toxic indoor environment. It’s good news all round really.”

She said: “I’m really grateful to the Yorkshire Agricultural Society for sponsoring me – it wouldn’t have happened without their support. This is a fantastic opportunity and I’m really looking forward to it.”

Almost 200 people have stayed in the Straw Bale Cabin, which was the first of its kind in the UK, and has attracted widespread interest. But, says Carol, straw bale building is still little-understood in Britain, with less than 100 buildings nationwide.

“They are permanent buildings, with lime rendering on the outside and clay plaster on the inside, and we have sheep’s wool insulation in the roof,” said Carol. “They’re warm, comfortable places that are totally natural and use local resources where possible – for example the clay, hemp, timber and so on.

“There’s no reason why more straw bale buildings shouldn’t be constructed and my study will assist me in learning more about how this could happen. It’s more widespread in Canada and the US, which is why I want to visit, and seeing how using straw bales works in Europe will be interesting as their climate is closer to our own.”

Sell-Your-Own-Energy-Back-To-Your-Supplier-Renewable-Energy





Did you know you could be making money from the electricity generated by your renewable technology installation?

If you have installed, or are thinking about installing, a renewable technology which produces electricity, such as a Solar Electricity (PV) system, you may be able to get paid for the electricity it produces. The most common way to do this is to sign up to a buy back scheme with an energy supplier. There are two main tariffs available to do this:
Export tariffs: You are only paid for the electricity that is exported back to the electricity network (you are not paid for any electricity you use). Generation tariffs: You are paid for all of the electricity that your system has generated even if you use it in your own home. There are also some Set Price Tariffs available where a fixed amount is paid by the energy supplier based on the type or capacity of the installation.
Use our buy back tariff search tool
To help you find the right tariff more easily we have developed a buy back tariff search tool. Using this tool will allow you to see details of all the tariffs currently being offered by the energy suppliers.
Click here to go straight to the buy back tariff search tool
Before you start your search you may wish to read the guidance below.
Choosing the right tariff
The answers to the following questions should help you choose the right buy buy back tariff for your situation:
Do you expect to use most of the electricity you generate at home?
If the answer is yes, it is likely that a Generation Tariff is likely to be a better option for you as you will get paid for all the electricity you generate rather than just the electricity that is exported.
If you will be using a small amount of the electricity your system generates then an Export Tariff may be a better option for you.
Will you need to install a new meter?
Total Generation Meter: Most tariffs will require you to have an Ofgem approved Total Generation Meter which should be installed with your system. Total Generation Meters give a running total of the electricity generated by the system in kilowatt-hours (kWh). Export Meter: Most export tariffs require you to have an export meter installed. Some companies will pay for the meter and its installation whereas others may charge you. It is important that you establish the costs before agreeing a contract. Will it affect your import supply?
Most buy back tariffs are dependent on the customer getting their import supply from the same energy supplier, and some suppliers limit the choice of available import tariffs that can be used.
You should check tariffs are on offer from the supplier purchasing your electricity generation and how much your annual bill will be. You will want to take these costs into consideration alongside the export/generation tariff payment.
What else should you consider?
Renewable Obligation Certificates (ROCs) are certificates given to registered generators of renewable electricity produced and sold within the UK. You will be entitled to one certificate for each megawatt hour (or 1,000 kilowatt hours kWh) of electricity you produce.
Some tariffs include a price for ROCs whereby the energy supplier acts as the ROC agent, claiming ROCs from Ofgem on behalf of the customer. However, there are other tariffs where the customer retains the ROC entitlement and must claim these themselves. For ROCs to be able to be claimed you must have a Total Generation Meter installed. Information on which tariffs include a payment for ROCs can be viewed by looking at the tariff details on our buy back tariff search tool.
Some suppliers include the payment for ROCs within the tariff, this means the ROCs are claimed by the energy company on the customers' behalf. If the tariff does not include payment for ROCs then the customer can claim for them separately.

What-Can-I-Do-To-Help-The-Planet-Earth?



There are a number of things you may do for our planet. Let me try and give you some suitable answers to help you out a little.

Fossil Fuels: You can 'Lower' your dependence on fossil fuels. I don't expect you to go run away and live in a cage or become a 'Tree Hugger' but you can, for example;

1. switch all your lights from incandescent filament lamps to high efficiency low energy compact fluorescent lamps.

2. Strip out the gas fire and install a wood burner (Wood is a carbon neutral source of heating fuel) They can come with a back boiler so you can feed the excess heat into the heating system to heat other rooms.

3. Cut back on the travel by (Car / Van / Bus / Train) and try cycling short routes. If your distances are large for commuting then why not set up a car sharing scheme with friends so you can all commute in the same vehicle and save burning excessive fossil fuels (Petrol and Diesel)

4. Buy your fresh vegetables from local farmers / farm stores, supermarkets fly / ship fruit and vegetables from all 4 corners of the globe and add to the excessive burning of fossil fuels. Why not support your local farmer and purchase his vegetables and fruit that were grown in the field next door and delivered by hand by the farmer himself?

5. Try educating others about turning lights off when they leave the room, why have the radiator in the lavatory on full when you are in there for 2 minutes 2 times a day? Try and see logic!

6. Swap your CRT (Cathode Ray Tube - The Big Glass fronted TV's) TV with a LCD flat screen one. They use much less Electricity (Which is mainly produced by burning fossil fuels Diesel & Gas)

7. Set your Laptop and or desktop PC to hibernate after a set amount of inactivity so it is not needlessly wasting Electricity.

8. When you go to bed for the night go around the house and switch off all non essential electrical equipment at the plug, putting TV's and Microwaves into standby does not shut them down but only puts them into a lower consuming mode.

9. Grow your own fruit and vegetables, it is so much fun and very satisfying, plus you get to know you are reducing your carbon footprint whilst getting free food!

10. Opt for as many bills as possible to be sent to you electronically, you save them printing them on paper, save the rain forests and save on the delivery van burning fossil fuels in the process!

Hope this helps you out a little.

Learn-About-Backup-Generators-For-Off-Grid-Installations


Backup Generator AKA: The gas guzzler

Off-grid solar-electric systems can be sized to provide electricity during cloudy periods when the sun doesn’t shine. But sizing a system to cover a worst-case scenario, like several cloudy weeks during the winter, can result in a very large, expensive system that will rarely get used to its capacity. To spare your pocket, size the system moderately but include a backup generator to get through those occasional sunless stretches.Engine generators can be fueled with bio diesel, waste oils (Including WVO, WMO, Gear Oil) petroleum diesel,gasoline, or propane, depending on the design. These generators produce AC electricity that a battery charger (either stand-alone or incorporated into an inverter) converts to DC energy, which is combustion engines, generators tend to be loud and stinky but a well-designed solar-electric system will require running them only 20 to 100 hours a year.

Producing-Power-From-Solar-Heat

A Solar Water Heater with a nominal capacity of 100 Litres/day costs about US$ 400 in India. The Govt gives this US $ 400 as a loan at 2% per annum interest( normal loan interest is 14%)

I saw an interesting web site which describes a demonstration plant for producing power from Solar Heat

Solar-cooking

Using the free heat of the sun to cook our food is easy, fun, effective and energy efficient Using the free heat of the sun to cook our food is easy, fun, effective and energy efficient. It not only replaces the fuel you would have paid for, but during the warm months, it saves on cooling costs by not heating up the house. Solar cooking has several other benefits, such as lower cooking temperatures will not burn foods, so stirring is not required.

The slower, gentler cooking provided by many solar cookers preserves more nutrients, as well as flavor and aroma. Food can simply be placed in a solar cooker and left to cook, unattended, for several hours. I've heard that some folks will place their food in the solar oven, point it to the noon sun, and leave for the day, coming home in the evening to a hot, cooked meal. However, if you are available to adjust the cooker to track the sun, it will get hotter for a longer period, cooking food in a shorter time. I made a small table, which rotates, so when I am passing the cooker, I can easily adjust it for maximum solar input.


There are two basic types of solar cookers, the box cooker, which will perform as an oven or slow cooker, and the cook top, which functions more as a stove top burner, heating the food just from the bottom of the pot. There are many variations on these types, ranging from basic boxes made from recycled materials to high tech, expensive models.

The box cooker is the most common, and easiest to construct, the links below have plans for many designs. I have built several; the advantage of the commercial models is ease of use, longevity of the materials, and convenience.

I am now using a commercially made box cooker nearly every sunny day, we bake breads, cookies, and cakes in it, I make beef jerky, rice, beans, soups stews, and casseroles with it.

Solar cooking has many advantages, and is a low cost way for anyone to use solar energy. The links below contain much information on the subject, plans, where to buy commercial cookers, recipes, instructions, and lots more. Have fun!

Home Power magazine has collected information about a wide range of
different wind turbines that are available for home or small business use.
The 2007 Wind Turbine Buyer’s Guide is a small but information-packed
article with a wealth of information about available turbines for small wind
systems.
The review has information on 19 different small wind turbines ranging from
7 feet to 56 feet in diameter, including systems for battery charging, as
well as batteryless grid-tie systems.

Can-Cars-Really-Run-On-Water?


Does the “water-powered car” really work?

Yes, but the water has to come from unicorn tears.

Unsurprisingly, inevitably, rising gas prices have brought increased interest in the water-powered car. Is there really a simple technology that can dramatically boost the efficiency of conventional cars or, better yet, allow you to run your car entirely on tap water?

Cutting-Back-The-Oil-Crisis-Is-Here!

Well, I have been extremely busy lately with Home Brew Power. The business end as apposed to the Website end of things.

It seems that the Oil Crisis is finally impacting on the lives of every day people. The Fuel is going through the roof, both Diesel and Petrol are at record highs, the Oil prices (Fuel Oil) is driving people to look for real alternatives now.

Is there an easy solution to the problem? Answer, NO. You all now need to look at your energy footprint and start to look for ways to reduce it as much as possible without freezing yourselves to death.

Fixes to help:

1. Energy Saving lamps throughout your home, garage and outside lights are now a must do.
2. Leave a room, turn the light off
3. No more appliances on standby, when you have done with the TV, CD, DVD, MP3, Xbox, PS3 etc TURN IT OFF! Unplug it, that way there will be no phantom loads.
4. Have TRV's (Thermostatic Valves) fitted to your radiators, the rooms your not in, turn the heat down in the winter, you would be surprised how much GAS / Heating Oil you can save by doing this!
5. Have your home Cavity Wall Insulated, again a great way to save valuable heat escaping on a cold day / night.
6. Put on an extra layer of clothing on an evening, it's not that hard to do and will save you money!

All I can say is the situation is going to worsen from here on in, oil is finite, it will run out and we need to look for viable solutions to the 'Soon to be upon us' Energy Crisis. For now I suggest we all look at the waste energy and do something to reduce it ASAP.

I am seeing more and more people asking me about the possibilities of CO-GEN / Micro CHP systems for homes, it is something I see will fast become common, people and families will become self sufficient and off-grid, away from the hungry power companies and greedy suppliers. Solar PV, Solar Thermal, Geo Thermal, Ground Source Heat Pumps, Micro CHP, Wind Turbines will all become common sites within our cities and streets over the next decade.

Solar-Fire-Project-Info

http://www.solarfireproject.com/home


Solar Fire Technologies offer one of the most cost effective ways to concentrate and use solar energy. Helping people and saving our environment is our driving vision.

By providing abundant, affordable and clean energy, the Solar Fire Project is a tool in the interrelated fights against global warming, deforestation, waterborne disease, pollution, desertification, soil degradation, poverty and general unsustainability.

Powerful enough to bring a liter of water to boil in 5 minutes, Solar Fire Technologies are do-it-yourself machines, on the same level of complexity as a bicycle. They are built from widely available materials, and simple enough to be operated by a child. Once built, SF technologies can meet the basic energy needs for a family for more than 10 years.

IMAG-Induction-Motors-As-Generators

They will need capacitors to work. The newer metals used in some motors are more efficient as far as the hysteresis losses go. That means a few of them don't have the
'fault' of having residual magnetism. What's good for a motor is, in
this case, bad for the generator start-up.

I think where the confusion is starting may be from the planned usage.
In a grid tied IMAG (Induction motor generator) the thing will spin like
a motor until you apply motive power to it. It has to spin a bit faster
than the synchronous speed in order to generate. This setup is pretty
much fool proof. You start it as a normal motor and should the grid go
down, it stops generating. Note that you HAVE to start it as an electric
motor FIRST, from the line.

Now, IF we don't want this IMAG running constantly, there has to be a
mechanism to ensure that it will be running in phase with the power
lines when we connect. It can get expensive, but a cheap method involves
the use of a light bulb placed in parallel with a breaker which is in
the line going to the grid.

The operation starts by bringing the motor up to speed with your prime
mover. When the generated power is in sync with the line, the light bulb
will go out and the breaker can be closed. The rotor is now locked to
the line frequency.

That last setup requires the capacitors you speak of in order to start
generation from the residual magnetism. It is an isolated system at
start up and needs its own reactive power.

For line connected, grid start motors:

The simplest inter-tie allowed is with an induction generator which is
excited by the grid, so *no* problems with synchronization. The
generator is turned somewhat faster than synchronous speed so there is
positive slip and generates power into the grid as long as the grid is
powered. This power grid is an "infinite buss" and gives all the kVAr
required to magnetize the generator and accepts all the kVA the
generator can produce.

So far so good! When the power goes off, then the induction generator
unloads and must be protected from overspeed etc, and even though there
may be fuel available and the engine could be run, it cannot generate
backup power.

Grid Connection Required


On the page about the permanent magnet synchronous generator we showed
that it could run as a generator without connection to the public grid.
An asynchronous generator is different, because it requires the stator
to be magnetized from the grid before it works.
*You can run an asynchronous generator in a stand alone system, however,
if it is provided with capacitors which supply the necessary
magnetization current.* It also requires that there be some remanence in
the rotor iron, i.e. some leftover magnetism when you start the turbine.
Otherwise you will need a battery and power electronics, or a small
diesel generator to start the system).
