Comments on: A Refrigerator Powered by the Sun http://theferrisfiles.com/2009/12/solar-refrigerator/?utm_source=rss&utm_medium=rss&utm_campaign=solar-refrigerator Journalism by David Ferris Thu, 03 May 2012 17:23:48 +0000 hourly 1 http://wordpress.org/?v=3.2.1 By: Stephen http://theferrisfiles.com/2009/12/solar-refrigerator/comment-page-1/#comment-1771 Stephen Thu, 03 May 2012 17:23:48 +0000 http://theferrisfiles.com/?p=1426#comment-1771 Einstein invented (well; agreed to have his name put on) a patent for an ammonia cycle refrigerator. They have been used for almost a century as a fuel-powered refrigeration source, commonly in recreational vehicles, boats, etc. They can be easily converted to solar power, and have been for years. Not a new idea, but ethanol/methanol is certainly much safer than ammonia. Einstein invented (well; agreed to have his name put on) a patent for an ammonia cycle refrigerator.

I am a school teacher, major in Physics, I like to read about alternative energy a power saving innovations. I highly congratulates your group for the great achievement! Hopefully poor people in our country and around the world can benefit from this kind of fridge! Blessings! Jose Rojas, Miami, FLorida Hi there!

Intriguing stuff! Solar energy has constantly been a fascination with me. I’ve enjoyed reading through these types of blogs. Intriguing stuff! Solar energy has constantly been a fascination with me.

Send your queries to Craig Somerton, a professor at Michigan State University who has led research in solar refrigerators. Craig furnished much of the information I've published about the solar refrigerator. You can reach him through his webpage, here: http://www.egr.msu.edu/me/people/profile/somerton Good luck!

Volker do you have any design would like to build it.

We designed for 39 degrees for vaccine storage. Vaccines can't be frozen and they can't get too warm. With methanol the vaccine storage would use ice made in the solar refrigerator. Sometime we should discuss our freezer for desert climates. Another unusual technology for freezing things. Cheers, John David-
