Renewable Energy Still Lacks a Storage Medium; Where are the "Shipstones"

The wind blows anytime, but not always and the Sun shines regularly, but only for less than half the day. Until there is a cheap and large storage medium the limits on the use of renewable energy will loom large.

The batteries are coming, but slowly.

In the meantime, as Solar, etc. covers greater & greater area, it'll get harder and harder to find total downtimes.

Brew,
Switching solar around still leaves 10 hours a day with no production!

Current physics pretty much caps current battery theory at a max increase in capacity of about 8%.

There need to be some bright people encouraged to put a lot of time and energy into looking for answers here.

Until we get reliable, massive and long-term storage there are limits that won't be broken. Thank god we have lots of Natural Gas.

Use solar to pump water up hill into a reservoir, and use that water overnight to generate electricity. Solar to mechanical to potential to kinetic to mechanical to AC

Thumper,
Loses are to high, efficiency is below 5%, lower even than batteries.

It is better than nothing. The pools indirectly store solar energy.

Thumper,
Grand Coulee Dam does what you're talking about, but includes irrigation as well.
