a miracle of the SUN!
A
solar grill developed by Professor David Wilson at MIT allows users to
cook emissions-free day or night. The grill uses a Fresnel lens and
solar energy to melt down a container of
Lithium Nitrate, which acts as a battery storing thermal energy for up
to 25 hours. The stored heat can be used to cook at temperatures above
450ºF.http://tinyurl.com/mf8x2o9
