What wrong with large leaves? We may use a
biotechnological process to recycle water. Point is
that cost will be the determining factor. Some
alternatives may require a lot of energy-- some not.

If the energy is free, then the cost is minimal. For
example, the solar energy to produce ethanol plants may
be an energy sink but the cost may still be less than
pumping the oil with it's infrastructure costs (which
the govt may pay for, but is still a cost nonetheless
to all of us) and shipping oil here and refining it.
Thinking out of the box wont help if there is no one to
finance the money for development. We have a lot of
good ideas but no money to develop them. That is the
reason why we start to consider these ideas when oil
gets up to $100 vs $25 a barrell. We are somewhat of a
self-indulgent people with little foresight, and do not
consider it bad that car manufacturers etc, would try
to block funding for this type of development. The
self-indulgent part comes from being happy in our
ignorance. |
