Incandescent light bulbs — a problem solved

Incandescent light bulbs waste huge amounts of energy as heat. LEDs solve all the problems of incandescents, but one: some people find the colour of the light they give unacceptable. Until now:

WHO Study – mobile phones "possibly carcinogenic to humans"

Another study, this time from the prestigious World Health Organisation (WHO), suggesting that mobile (cell) phones pose a cancer risk.

Perhaps the most interesting point (at the end of the podcast) is that 3G phones result in less absorbed radiation than GSM.

Safe Atomic Fission Energy From Thorium?

We've heard promises of safe, cheap atomic energy using uranium before, but thorium has a range of advantages, including being much more abundant &, maybe, safer:

http://m.smh.com.au/environment/energy-smart/the-reactor-that-saves-itself-safe-nuclear-does-exist-and--china-leads-the-way-with-thorium-20110323-1c6eb.html

So if thorium has so many advantages, why has humanity persevered with uranium for so long?  It has been suggested by many, including the article above, that uranium use has been driven by military interests (in several countries) that want to use uranium (& its daughter element plutonium) for bombs.  Notch one more up for thorium.
