Three Solar Food Dehydrators – solar energy at work!

www.permies.com The first solar dehydrator is shown by robert and marina at dell artimus farm. The solar heat comes from a heated panel at the bottom, and there is a black chimney at the top that creates a draw. They use a stainless steel screen. The dryer is a year and a half old. They have dried beans, flowers, cherries, grapes (raisins), kale, walnuts and apples. They tried some tomatoes, but those ended up as pig food. Matt at feral farm shows a “down draft solar dehydrator.” The solar heat enters at the top and then goes down. Because as it gathers moisture, the solar heated air gets heavier. He has nettles in there. Mark Vander Meer, of wildland conservation service in Missoula, Montana shows off his solar food dehydrator still loaded with dried plums. Those plums have been in there all fall, winter and most of the spring. He talks about trying to dry fruit with electric food dehydrators and how expensive that was. This solar dehydrator also uses the down draft technique. He says plums take three days and apples take a day and a half. These are all passive systems. There are no fans.

Why Solar Energy? (HD)

Free Energy From the Sun: THE clean, never ending resource! Onbeautiful Seabrook Island, nestled on the coast just south of Charleston, South Carolina, lies Camp St. Christopher It offers over 300 acres of beach, marsh and maritime forest and multiple facilities including meeting and conference centers, lodging, and worship centers. We’re excited about keeping you up-to-date on our progress and informing you about how this project was made possible. The process began last August when the State Energy Office put out information that there were going to be .9 million available in grants for alternative energy projects for non-profits. As soon as we found out, we immediately started getting in touch with local Charleston non-profit organizations to inform them about the opportunity. When St. Christopher responded about being interested, we setup a meeting for late September 2009 and went out to view the grounds and start planning. The RFP from the State was issued in early September. The government was looking at multiple factors before approving a non-profit like St. Christopher for the grant. These included visibility of project, potential job creation, overall benefit in terms of investment and payback of the project (they needed a minimum return of .50 dollars to spent). The grant writing process was long and hard, but St. Christopher didn’t have to worry about that. SES took care of making sure the grant was completed correctly and on time. Anything we were able …

Using Heat Shrink Tubing & Hooking Up Alligator Clips To A Solar Panel

In this video I show you a professional solar panel I purchased, and since I only plan to use the solar panel as a temporary solar panel for different projects, I’m going to install some alligator clips on the leads so I can easily hook up the solar panel to devices and unhook it. To complete this simple task, I also wanted to use heat shrink tubing instead of just regular electric tape to hide my connections. This is a very easy project that almost anyone could do, and not with solar panels but with a wide range of devices that use DC connections. For my full video on how to build a solar panel from scratch visit: www.solartechtown.com If you wish to purchase this solar panel, I will be posting the link on my blog at http If you have any questions feel free to visit our forums at Solar Tech Town.

How to Make Solar Panel – A Quick And Easy 101 Guide to Solar Energy Production

www.energybrainiac.com – How to Make Solar – A Quick And Easy 101 Guide to Solar Energy Production Making a solar at home is quite a daunting task and something that shouldn’t be attempted without fully committing oneself to a great deal of work. It may not be rocket science but it is certainly a tricky and laborious process. If you are the type of person who thinks a hammer is nothing but am odd-shaped door stop, it may be in your best interest to leave the solar construction to professionals. Having said that, making your own solar s can really be a rewarding home project and by taking on such a project yourself you can significantly cut your costs – by 50 to 80% – over a commercially available solar . Since the prohibitive cost of solar s is in large part due to the high price of solar cells, you will achieve most of your cost reduction by purchasing damaged and used solar cells from sites such as Ebay. After that, using your ingenuity and some handy DIY skills, the only thing between you and a working solar is time and effort. For now however, let’s take on a much more simple task and make a single solar cell. This project is great fun and can show the basic and simple concept behind solar energy. What You Will Need 1. Copper sheeting. 2. Two alligator clip lead cables. 3. A sensitive micro-ammeter you can find this at Radio Shack. 4. An electric stove or a one burner hot plate should you have a gas stove . If you are buying a hot plate make sure it’s at least 1100 …
