A bank for wind power

Here's one for the wind power naysayers - various methods of storing off-peak wind-generated energy to use during peak times. Including 'flow batteries', whereby once the battery is fully charged they move the chemicals to a storage tank, fill the battery up again, and charge that - resulting in huge tank of stored energy. And hydro-schemes which pump water up to the reservoir using wind power, then open the sluices for hydro power when needed. Which goes to show that you can't write wind power off - the more we invest in it, the more we'll learn about how to make it more productive and practical. (Log-in required I'm afraid.)
