Toyota Winglet-Testing In Japan

This Winglet measures “10.4 x 18-inch footprint and stands 1.5-, 2.2-, or 3.7-feet tall (depending upon the S, M, or L model chosen)”.....

A major discovery of research in Solar Energy is done by MIT’s Energy researcher. The problem with Solar Energy today is that the Sun only shines at days, so there will be no energy source at night. Though scientist had found out some ways around the issue, it was inefficient and very expensive. Today, MIT researcher announced they discover a inexpensive and highly efficient way to store energy.
This can be done by splitting water into hydrogen and oxygen using the sun’s energy. Then there is something called the fuel cell that recombines the two elements. “Requiring nothing but abundant, non-toxic natural materials” said MIT's Daniel Nocera. This might be the key to future energy saving resolution.
