(1) Fission works with elements downwards towards iron. Fusion works with elements going upwards. That's to say, to re- fuse a product of a fission reaction takes all the energy you got out back again.

(2) Do you know how far away the geostationary orbit is? It's about 22000 miles (the Earth's radius is about 4000 miles).

(3) This must be a wind-up. Use bikes and get fit. Walk. Don't travel so much unnecessarily. Live near where you work and the shops. Insulate the house. Don't have so many kids. Burn the lawyers.

(4) Unobtanium dilithide is better.

(5) Hope cold fusion works.

(6) Methane from poo. This may be a form of perpetual motion.

(7) geothermal power (what happened to that?)

(8) There must be a lot of power wasted when a region of meteorological high or low pressure passes over. If only we could convert that to motion, like a gigantic Newcomen engine...

(9) Find a way of extracting power from stupidity, it's an infinite resource.
