NF: "Any thoughts on the use of microwaves for power transmission." Yes, I say a dead duck. I'm a chemical energy fan. Fuel cells for small electronics seems a good system. Charging is a pain for electronics. Battery life is a pain with normal batteries - due to weight limitations and poor energy density. Unless the power demand for electronics can reduced to near zero, which they could do with micro cryogenics and superconductor technology, backed with super insultation techniques, there is simply too much energy consumed to transmit power to a mobile person. The whole city would need to be glowing hot. Anyway, the amount of power would be wasteful, even if you could target the particular handset with laser microwaves. With near zero power demand, they could use the background microwave radiation as energy source [4 deg K], alter the signal slightly and transmit slightly above that energy density, having accumulated power for 20 hours and transmitting only say 4 hours a day. Most people would call that science fiction though. Fuel Cells are high energy storage, liquid re-filled and ready to roll. With a little development work. They've been in use for decades in space. Batteries and energy consumption is a very important area of competition in the cellphone business, as you know. Power demand minimisation is the key! Mqurice
