Why is the wafer size SO much smaller than in Silicon/SOI manufacturing? 200mm wafers for chips was early 90's tech and the standard has been 300mm for over a decade with 450mm slated to be coming online about now if it hadn't been for the great recession and the shift towards mobile (ie Intel Fab 42 which is now in mothballs).

Comment It seems unlikely (Score 1) 21

It seems unlikely this was actually the first bird to pollinate a flower. Since the pollen was already too large to carry on the wind that would imply that the plant had already adapted away from self pollination and towards external pollinators, a process unlikely to happen suddenly.

American ruling class, the Clintons?!? Hillary came from a background where her dad was a small business owner whose parents were both the children of immigrant coal miners and Bill was the son of a salesman and stepson to an auto dealer. They both attended public high schools. These are people who succeeded through brains and hard work, not through birthright and who their parents knew.

Hardly, we make around 400m computers per year and a hell of a lot more labor goes into an assembled computer than a simple solar cell. Plus a .1% AFR on something solid state would be horrendously bad, mechanical hdd's (enterprise class) are at only 1.5% AFR and those are mechanical devices spinning at 15k RPM!

Per capita energy use in the US is ~300M BTU, or 90k kWhr, there are ~330M people in the US giving a total energy usage of ~30,000 TWhrs. Average solar insolation without tracking in Albuquerque is ~6.4kWhrs/m^2/day or 2.336 TWhrs per km^2 per year, at 10% efficiency you would need to cover 128,424 km^2 which is a bit more than 1/3rd of the land area of New Mexico.
