Solar Fire in India!! Solar Steam engine!
A number of months ago I posted about Eerik Wissenz from solarfire.org collaborating with V K Desai of Tinytech in India. They first built a 10sqM concentrator, then a 32sqM version and Mr. Desaiji has now completed a 90sqM concentrator, pushing Solar Fire technologies into the industrial realm.
Huge and beautiful, this machine will cook for thousands of people per day or run machinery for local industry.
I am captivated by the possibilities for this machine in Haiti. While institutional cooking is very exciting, I think this thing powering a rubble crusher in Port au Prince or in one of the nearby rubble fields could be tremendously empowering. Right now, the removal of rubble is very industrial, with dump trucks running huge bins of rubble to the outskirts where huge machines break them down. See this PBS story.
Rubble crushing is one thing, but this concentrator further lowers the cost of high quality solar thermal energy, something that I believe will be essential to the sustainable development of Haiti.
Mr Desai of Tinytech expounds on his system in a post at HEDON.
