Re: "Designer Climate"
- Lasallia, the simple and straight forward answer to your question
is that it is not economical to produce Solar Energy right now.
Unless the governement artifically (Think Farm Subsidies) makes
solar attractive it can not compete with fossil fuel produced
energy. Nuclear is not cheap but it is still less expensive and
easier to produce in large quanties than solar.
There has been a lot done over the past 20 years in alternative
energy sources. Swimming pool solar heat has been growing. Hybrid
cars are now on the road. This may not be as fast as some would
like but to assume we are comfortable with status quo is just not
It is my belief that it is over simplistic to assume the the Fossil
Fuel Industry (think Evil) is responsible to restricting our use of
alternative fuel sources. Why would they? They are in a prime
position to take advantage of new sources of energy. If the profit
were there they would do it. If they made solar Energy, who would
buy it? If you can't sell it why do it?

- I don't know what to say. Ross has 'figgered' that Lufkin hasn't
gotten any warmer so nowhere else has. Furthermore it seems that the
earth IS going to warm evenly and consistently .... but wait... he
suspects that the warming is a geographical phenomenon and that some
places will be cooling while others get warmer. Well, I'll be darned.
Respect has to earned, not demanded. When you earn my respect, Ross,
you'll get it.
