Alternative energy in the news: NASA are testing
a
combined solar/fuel cell, which may lead to solar electricity becoming
more efficient. The cell is being tested in an unmanned wing-shaped aircraft
which NASA hope to fly continuously for six months on solar energy.
Meanwhile, a man in England has modified his Land Rover
to
run
on used vegetable oil, with a small amount of diesel. He now gets most of
his fuel for free from school cafeterias; however, some bureaucrats say that
he is liable to pay fuel duty on the oil.
