Please see:<br />http://georgesworkshop.blogspot.ca/2012/08/gen20-first-steam-test.html<br />This work was all done with parts made from the design in my book.<br />I show how to make the solar collectors only. The balance of the system would be up to you. I show the temperatures and the amounts of steam that can be produced with even a small system.<br />Good luck George Plhakhttps://www.blogger.com/profile/11832386563569915660noreply@blogger.comtag:blogger.com,1999:blog-14977872.post-90611850363489894662016-04-08T03:42:48.198-04:002016-04-08T03:42:48.198-04:00Hello George,

I'm specifically thinking about compressed gas that creates differential pressure when heated on one side or the other shifting the angle to create equal pressure (aligning with the sun)Anonymoushttps://www.blogger.com/profile/13825749429295328331noreply@blogger.comtag:blogger.com,1999:blog-14977872.post-88726722823923705892014-02-14T12:34:00.725-05:002014-02-14T12:34:00.725-05:00How is your latest (gen2) book coming along?

I imagine it has to be pretty tough to handle the temp. I am hoping to make a system that can generate some pretty high water temps and circulate that water through a pot to boil a separate fluid. Does you book cover topics like this?

Ditto to the previous comment - great job!<br /><br />i bought your first book last year since we were looking for some tips for the collector that we had built. It is based on sheets of 10' x 4' galvanized sheet metal which we cover with Mylar 2 mil film. It works great! We're still looking for a better way to make the Mylar stick to the metal. Our first try was axle frazelle09https://www.blogger.com/profile/15408717848663803753noreply@blogger.comtag:blogger.com,1999:blog-14977872.post-45623409012319935212013-04-23T12:37:32.291-04:002013-04-23T12:37:32.291-04:00Hi George, congratulations for your great job and ...Hi George, congratulations for your great job and thanks for sharing it with everyone!
