By harvesting energy from radioactive specks, nuclear microbatteries could power tomorrow's microelectromechanical marvelsâand maybe your cellphone, too ..... THE FUTURE OF NUCLEAR MICROBATTERIES depends on several factors, such as safety, efficiency, and cost. If we keep the amount of radioactive material in the devices small, they emit so little radiation that they can be safe with only simple packaging. At the same time, we have to find ways of increasing the amount of energy that nuclear microbatteries can produce, especially as the conversion efficiency begins approaching our targeted 20 percent.

I've paid 300&8364; (470 CHF) for my new baby:&160; ALIGN TREX 450SE V2 I hope to be able to fly this 450 size not far away from my apartment in Zurich.

Toshiba has developed a Lithium-Ion battery capable of being charged to 80 per cent of its full capacity in under 60 seconds. Filling it up takes just "a few more minutes", the company boasted today. That's considerably faster than today's Li-ion rechargeables which can take 1-4 hours to reach 80 per cent capacity, and even longer to fill completely. more here …
