Do you know where your food comes from, and how it’s prepared?

Shell, and others, sponsoring Fuel Efficiency Technology

Shell is investing heavily into fuel efficiency and alternative energy solutions. Please comment on how you perceive the traditional oil companies are moving towards efficiency and environmentally friendly solutions. Read more about Shell’s Alternative Energy Projects.

Making Steam from Solar Energy – redux

A while back, Robert Saunders sent us an article on a steam turbine he was working on. Then he sent another on solar energy steam electric. Well, here is his third chapter in this continuing quest. Hope you enjoy:

Our vegetable oil burner has arrived

Steve Spence — Tue, 24 Feb 2009 09:56:40 +0000

We drove to Massachusetts yesterday to visit Tom Leue from http://yellowbiodiesel.com/, and brought back one of his Recycled Vegetable Oil (RVO) burners. This is designed to replace a standard 4″ Beckett burner in a boiler or furnace, can be installed in a drum for a shop heater, used to heat water, or even create steam for a steam engine powered heat and electric application (Combined heat and power, or CHP). We talked a bit a few days ago about this burner in a previous blog article, which gives more info on the burner itself. This design is based on a Babington burner that injects air through a tiny jet in a ball, and pumps oil over the ball, forming a ignitable vapor when the oil covers the jet of air, similar to a whale’s blowhole. Discussions of the Babington principle are commonly held at http://group.wastewatts.org.

Windy Days at Green Trust

Steve Spence — Wed, 18 Feb 2009 23:10:28 +0000

We finally got the AIR-X (400 watt) wind turbine raised today, just in time for a windy mini blizzard. It sits on 30′ of 3″ galvanised pipe, bolted to the side of the house. We used a backhoe to pull a rope, connected to the tower at the 20′ mark, over the top of the house, as we didn’t have the manpower to pull it ourselves. We put two other ropes on either side of the turbine to keep it from sliding perpendicular to the direction we wanted to to go.

I don’t have my anemometer up to check wind speeds, but the turbine is peaking at 300 watts and singing like a stool pigeon. I have the output of the turbine (the negative) running through a shunt connected to my FLEXnetDC battery monitor, so my Outback Mate tracks the power the turbine collects. My solar panels connect to another shunt, and my inverter to the third shunt. This gives me detailed information on my production and usage.

I have some of pictures of the process posted at http://sspence65.jalbum.net/AIR%20X%20Install/ and more coming shortly.

The Whisper (500 watt) is the next unit to go up, followed by the rebuilt 24 volt (was 12v) 1000 watt Axial Flux Turbine.

Heat your home and hot water with vegetable oil

Steve Spence — Wed, 18 Feb 2009 13:22:17 +0000

Tom’s vegetable oil fueled Beckett burner replacement is idea1 for heating your home with cheap, clean burning renewable fuel. Requires no pre treatment or filtering. It’s based on the Babbington vaporization principle. Works with air furnaces, as well as water boilers and homebuilt units. Read more at http://drop.io/YellowHeat.

Brainstorming battery technology and human power

Steve Spence — Wed, 11 Feb 2009 13:27:37 +0000

Melvin Martin was over last night. He’s greatly recovered from his accident, but still has a ways to go. We were discussing home built NiFe (Edison) batteries and how to make your own. These batteries have the ability to last 50+ years, and we have a bunch of info on them in the files section at http://groups.yahoo.com/group/12VDC_Power/files/. We were also discussing human powered devices, specifically pedal powered water pumps, grain mills, and electrical generators. I have had a very good resource for this for 20 years called “Pedal Power: In Work, Leisure, and Transportation”, and just picked up a wonderful companion to it produced in 2008 called “The Human Powered Home”. Detailed drawings and parts lists for mixers, pumps, grinders, and many other projects where fuel or electricity may be in short supply, or you just need to lose 50 lbs. These books and more can be found it the Human Power section at http://www.green-trust.org/bookshop/.

Free heat from our Solar Window Heater

Steve Spence — Tue, 03 Feb 2009 17:55:42 +0000

Would you like free heat from the power of the sun? We have a Solar Window Heater that can produce 130+ temperatures. It’s 18″ x 24″ x 10″, weighs 9 lbs., aluminum cased with a glass cover, and sets in a south facing window. The twin 12v fans can be powered with the included ac adapter, or with an optional solar panel. The integrated digital thermometer shows the temperature of the air flowing through the box. To order this $130 unit at the Green-Trust special of only $98, go to http://ussolarheating.com/sampler and tell them you saw it at Green-Trust. This special comes with upgrade privileges to larger units.

For larger units, contact us at steve@green-trust.org .

AIR-X Wind Turbine Arrived, More Rocket Mass Heater Videos

Steve Spence — Tue, 13 Jan 2009 03:55:22 +0000

The 24v AIR-X arrived today, and the Whisper 500 watt unit arrived last week. The Whisper was donated by Jim Juczak of woodhenge.org. Allan Smith, the creator of the Rocket Mass Heater came for supper, and we discussed his design, and alternative implementations. We will be building one of these soon. A ebook of the heater with video and Sketchup diagrams will be available from us shortly, as well as one with the wind turbine setup and installation. He has also added a couple more video’s on startup of the heater, and heat circulation. The manual wood splitter mentioned in the video’s is found at Bailey’s Online.

Allan’s Rocket Mass Heater

Steve Spence — Fri, 26 Dec 2008 14:15:52 +0000

A friend of mine just posted his working version of a Rocket Mass Heater on Youtube. This is a great example of a clean burning, extremely efficient heater that can be used for space heating, cooking, or heating water, or any combination of the above.
