I wouldn't make large windmills, I would make many small ones that could handle high winds. They could be installed very quickly and easily; they would also be hidden behind grills.
To me this was a missed opportunity, all that wind could have added 3 or 4 months of Electricity to the Grid. If someone invented the low cost high capacity battery, it would change everything. There could be tower blocks filled with batteries that stores surplus power then sends it back to the grid slowly when the power levels are low. Even if one kilowatt-hour of power costs 10p, a 50 kilowatt-hour battery would store £5 worth of power. It could discharge millions of times if it is made of a more robust material that doesn't wear down. Even if it discharged 1000 times, that would be £5,000.
I am an ordinary man but I know the impact of a 'Low Cost High Capacity' battery would have on the whole world. Everything would change.
