Zeev's Turnips Patch-No Politics (ZEEV)

[Zeev Hed]

Very antiquated calculations, it can be done with today technology at half that, and it is laughable when the author talks about :"shortage of materials", silicon is sand, and sand is almost as abundant as water... it is also laughable when he talks about availability of land, your roof, which is a wasted piece of real estate is the "required land" for a good chunk of the required power (a normal house can supply its energy requirement with less than 100 square meters of solar collection, show me a roof smaller than that in suburbia) but I am not going to go into an argument about it here. I have said long tim e ago that there are two issues, energy independence and potential greenhouse effect from the use of fossil fuel. Frankly, the former is more important, IMTO, than the latter (another Saint Hellen could compensate for 10 years of excessive CO2 discharge, and reforestation to improve the natural carbon cycle could do the same thing, just double the area of forests in the world and you absorb a lot of that CO2 discharged. As for energy independence, we have as much on the north America continent as we'll need for the next 30 years, and if crude stays above $30/barrel for good, it makes financial sense t extract it profitably. That is why Saudi Arabia, is not going to let crude stay that high (except adjustment for the falling dollar) for long, the don't want Canada to develop its shales deposits.
