A few days back, bio-diesel powered coffee rooster was making a lot of news. To make things more interesting as well as environment friendly, Mike and David Hartkop have developed an ecological coffee rooster being run with solar power.
This amazing solar coffee rooster acts as a parabolic mirror array and eventually heats up the roasting drum at 600 degree Fahrenheit. Motors of this drum are also being powered with solar energy. When the sun is shining, roaster can effectively brew 7 pounds of coffee within an hour.
