Meanwhile, the U.S. does nothing. Even acknowledging that maybe we don't want direct, multi-billion dollar allocations from Ted "Bridge to Nowhere" Stevens and others to develop these schemes, what about tax breaks and incentives for private sector R&D into solar? What about "aid" in the form of low-interest loans? I'm not a policy-maker, but there are options.
Actually, we've done something: in 2002, President Bush "installed 'building-integrated photovoltaics' or BI-PV solar electric generators at the White House for personal safety and national security." I guess that means the Administration believes in the technology.
It's the "personal safety" of their financial portfolios that's throwing them, I guess.
