Hi,

BTW, it only costs about 0.53 kWh/kg to lift something 200 km above the Earth's 
surface against gravity. Li-ion cell
phone batteries have about half that. However gasoline is about 12-14 kWh/kg, 
less when you need to take along your own
Oxygen. Ideally one would use a small nuclear or isotope reactor.
