Solar Heated Water: Create Your Own Evacuated Vacuum Tube

2009-08-20T19:19:52Z

Awesome videos about evacuated tubes... how you can create your own and how it will heat water to a boiling point using the sun and a mirror.

Evacuated Solar Cooking Pot

2009-08-19T19:12:34Z

This is a really cool cooking concept that eliminates the need to replace oven bags in solar cooking.

Just take this pot and place it into a funnel of mirrors or a funnel of aluminum and it will easily sterilize or even boil water in direct sunlight.

For project 10 to the 100th my idea is a solar cooking oven that uses double-lined evacuated glass for the cooking food and disinfection of water.

Now all we need is a manufacturer. Anyone have any leads there?

Butterfly Community Solar Cooker from TinyTechIndia

2008-12-05T07:16:53Z

Tiny Tech India has come up with a new version of a parabolic solar reflector called the Butterfly Community Solar Cooker.

According to the web site, it's advantages are:

As there are two equal reflectors - one on each side-, weight is balanced and hence it does not require foundations in the ground. It is mounted on 4 castor wheels and can be revolved and shifted in any direction at any moment even while cooking. In Scheffler Reflector, it is essential to fix the cooker with ground by RCC foundations.

It is not necessary to find out north south direction. In Scheffler Reflector, it is essential to fix north-south line and fit the cooker on that line.

It does not require to install on polar axis. So no latitude of the location is necessary to know. In Scheffler Reflector, it is essential to fix entire structure to revolve around polar axis and hence latitude of the location must be known.

It does not require any seasonal adjustment. In Scheffler Reflector, it is essential to make seasonal adjustment every week.

It is dispatched in dismantled condition and it can be assembled at site very quickly without any expert guidance. So installation staff is not necessary. In Scheffler Reflector, it is essential to send expert person for installation.

100% reflector area is utilized as aperture area as against 70 to 80 aperture area is used in Scheffler reflector. So 8 sq mt butterfly is equivalent to 10 sq mt Scheffler reflector.

Both wings (reflectors) can be folded vertically on hinges very quickly. Hence when not in use, it will occupy very less space.

It can be quickly adjusted against focus by any layman without any training.

The cost of Butterfly cooker of equal capacity is only 50% of Scheffler reflector.

John Grandinetti's Indirect Solar Cooker

2008-11-19T08:58:40Z

Mr. Grandinetti's oven can be made for about $21 dollars and here's the kicker: he is giving it away. He doesn't want to sell the plans, he wants a company to take it and mass produce it for third world countries so that forests won't need to be cut down for things like cooking fires. A noble idea indeed. It will be interesting to see if any company, anywhere steps up and takes him up on his offer.

John Grandinetti is a solar contractor out of Honolulu, and the owner of Grand Solar Inc. This isn't his first foray into the solar cooking/pasteurization field. He also has created similar devices for the purpose of pasteurizing water in the late 90's for third world installations in Tanzania and Guatemala.

]]> This is an Indirect Cooker.

According to SolarCooking.org:

Indirect cookers separate the solar energy collection element from the cooking area, using a heat transport medium to bring the collected energy into the cooking area. Hypothetically a solar collector could be placed several feet away from the cooking area by using this technique. This would allow the collection elements to be placed on the roof, for example, with the cooking area located within the home.

SolarCooking.org also says:

In 2008 John Grandinetti publicized his Evacuated Tube Indirect Solar Cooker, which has some similarities to the Whiller indirect solar cooker. Grandinetti's design replaces the finned pipe with an evacuated tube solar collector as the collector element, and uses vegetable oil instead of water as the heat transport medium. With these changes and some other refinements, the design provides a practical solar appliance. Tests have indicated the unit can reach cooking temperatures (300°F) with 1 hour of morning sun at tropical latitudes. Cooking, water pasteurization and autoclaving can be readily achieved throughout the remainder of the solar day, with cooking times similar to an electric stove. Frying, baking, boiling and steaming have all been successfully accomplished.

Solar Water Heating and Solar food drying

2008-11-17T08:49:22Z

We wish they would have offered a little more instruction and a little less music in this video, but nonetheless, looking at their models, you can start to get some good ideas for both drying your food in a solar dryer, and heating your water using nothing but the sun.

Frankly, the music gets a bit annoying after a bit... but did you see how simple the model is for solar heating of the water? Pretty cool.

Solar Pizza Box Cooker Failure: Chocolate Chip Cookies

2008-11-08T20:23:32Z

I sped this video up to make it go a bit quicker. But basically, this is my last attempt at using this pizza box cooker. I was attempting to make chocolate chip cookies using the pizza box solar cooker, but it just didn't work, and I ended up cooking them inside in the oven.

Baked Apples: Solar Cooker Desserts

Baked Apples

Carrie has made us baked apples on a few occasions, and I have absolutely loved it. Now, too much sugar (or really, even a medium amount of refined sugar), may not be all that good for you, or for the environment, depending on where the sugar, apples, and cinnamon came from, and depending on how they were grown. So do a little research to know what you're eating before you're eating it.

Apples

Sugar, brown and white

Cinnamon

]]> Do not peel apples. Core. Fill cavity with sugars. Sprinkle with cinnamon. Place in dark pan. Cover and bake in solar cooker for 1 1/2 to 2 1/2 hours.

As with all recipes for solar cookers, your cooking times may vary, depending on the sun, your solar cooker, the temperature of your solar cooker, your location on the planet, and any other number of factors. Just remember that this should be fun to experiment with. Try a few different recipes, note the position of the sun in the sky, and try to make sure your solar cooker stays pointed at the sun the whole time it is cooking. Note how long it takes food to cook in your cooker, at your location, during the time of year you are cooking your food, and adjust the recipes accordingly.

Solar Cooking Workshop in Nyala, Darfur

2008-11-05T21:33:57Z

Nyala was the headquarters of the Daju empire, which was established around Jebel Um-Kurdós, until the fall of the Daju rule at the end of the 15th century, according to an account of sultan Daju Kassi Furok or Kassifrogé who mounted the Antelope from Darfur then perished in Dar Sila.

]]> When Great Britain conquered the Sudan, the British Commander in Chief met Sultan Adam Suleiman in 1932, seeking his advice for his knowledge of the best places in terms of availability of water sources and land topography in order to establish the British Administration Headquarter in Darfur. Sultan Adam Suleiman had chosen Nyala city for that purpose. However, many sites of ancient antiquities, pottery, engraved pictures of battles, horses, animals and hunting are still awaiting for further scientific archaeological work at Jebel Daju. The most important archaeological sites undiscovered yet are Nari, Kedingnyir, Dobo, Simiat Hills, Jebel Keima, Kalokitting, Jebel Wara, and Jebel Marra itself.

During the ongoing Darfur conflict, thousands of internally displaced persons have gathered near the city in the hopes of protection.

As the women look for firewood around the displacement camps they face the danger of rape and abduction. Solar cooking offers an alternative to using firewood for cooking.

Bander Beyla: Successful Solar Cooking in Somalia

2008-11-01T21:20:44Z

Bander Bayla was the first village in Somalia to be helped after the tsunami with solar cookers. Stoves were distributed to over 950 people. See pictures of this beautiful, remote, tsunami affected village.

]]>

Bander Beyla is an old, well-established but small and isolated fishing town on the Indian Ocean about 200 km south from the tip of the Horn of Africa. In December 2004, part of the town was destroyed by the tsunami.

Driving over dirt tracks to reach the coast, after many kilometers of flat dry land, a breathtaking view of a small bay, a town and a beach with white breakers suddenly opens up below. This is Bander Beyla, wedged between sculpted brown hills and the turquoise blue Indian Ocean with white breakers crashing onto silver sand beaches.

Sun Fire Cooking in partnership with Horn Relief and funded by the United Nations is distributing 950 solar cookers to this tsunami-affected town. Bander Beyla is credited with being the first solar cooking village in the world and has been a model for a forward for many places where sun is plentiful, but where people curently rely on charcoal and wood for daily cooking.
