Advantages
Environmental
concerns have prompted costly,
complex technological responses to
current emissions. Fuel cell
technology is one example. The
benefit of running on clean burning
hydrogen is more than offset by the
expense and bulk of the technology
as well as the cost of creating,
storing, and delivering fuel grade
hydrogen. (Air admitted hydrogen has
proven to be a GREEN HOUSE GAS,
forming ice crystals in the upper
atmosphere). Clean running electric
vehicles are limited to very short
ranges, and still must be recharged
by electricity from a coal, diesel
or nuclear-fueled power plant. Gas
turbines are clean, but are constant
speed engines. In small sizes they
are costly to build, run and
overhaul. Diesel and gas internal
combustion engines are efficient,
light, and cheap to manufacture, but
they are dirty and hazardous to
one’s health. Diesel, once thought
to be clean, as been proven to be
one of the most toxic compounds
known (New Science, Oct. 25, 1997). |
