I often see posted about how covering a relatively small area in a desert with solar panels could power the world – but transferring that energy is too difficult. Why can’t we just use that to charge batteries and ship them places/ everywhere?
In: Physics
Suppose you want to power the U.K. from batteries charged in the Sahara. A typical 3″ x 1 foot by 2 foot battery pack for electric cars is 80 kwh and weighs 1000 pounds. The UK daily electricy consumption is around 800 millon killowatt hours. You’d need to ship 10 million of those fully charged battery packs per day. Doesn’t seem even remotely feasible, does it?
