Everybody that has their first child is one of those people that don't have kids. Since you credit having had one with providing the knowledge of the fun that ensues it is clear that the first child is not had for the fun, but the decision is made for some other reason...

Aka, pay attention at the back.

Hell, it could /require/ them to buffer the grid.

People could book energy for particular slots of time. The cost of managing grid electricity would plummet.

The electric company would have to manage it to ensure that it really does draw the power it books, and draws it at the right time. But that's okay - it takes the risk out of it for the home-owner and pools it. For the grid operator, the risk is a tiny fraction (you need an awful lot of simultaneous failures to cause them a problem). The grid operator will also be well equipped to estimate the remaining risk, budget it, and limit the customer's liquidity at optimal times to minimise it - things the customer general isn't able to do.

Comment the only possible application? (Score 3, Insightful) 204

To use water and aluminium as energy storage. We already have a pretty good global aluminium infrastructure.

If water could be combined with aluminium to produce hydrogen on demand, then you refuel by replacement of the aluminium oxide waste with fresh aluminium and refilling the water tank.

Then you still need a better method to convert aluminium oxide to aluminium - but here's the great thing about this research. Better ways to convert in one direction usually lead to better ways to go the other way too (eg, microdots convert electricity to light better, but also the other way round too).

I'm wasting my mod points now by posting, but I can't let that lie. A volcanic eruption that can kill everybody spouts vast quantities of CO2 - that's how it kills them - it suffocates them.

The guy in prison would be the first to go because CO2 is heavier than air and would fill the gaol as soon as possible.
