7145Re: clean cars
- Apr 8, 2004Indeed static sources offer the possibility for less pollution, even
taking into consideration the energy losses from energy transfer and
energy form conversion - but unfortunately this doesn't happen always
(and CO2 sequestration is just "talk" for the moment). Even better
they offer also the possibility to use energy from renewable sources
(solar towers, wind turbines, waves, geothermal etc) - unfortunately
still in very few cases. This is the good scenario.
But the location shift of the dirty phase of energy consumption
creates also the opportunity to use profitably other less noble and
more polluting energy sources, like coal, lignite etc which could be
never effectively used on moving sources. In addition, environmental
standards can much more easily be lowered if pollution sources are
less annoying (at least directly) to the users (the majority of the
world population lives already in urban settlements according to UN
Which of the two scenarios do you think is more probable to happen
most of the times in a "free market economy"?
