This is not to say that these aren't interesting or won't become
important, but I'm guessing this isn't going to be a technology that
will sweep the field anytime soon.
Thanks. This is what I was thinking was probably the reality:

Even the latest devices, which are very clever in the way they saturate
a porous structure with the gas and thus usefully capture quite a large
number of the energetic electrons, have an energy density of the order
of twenty five watts per kilo. Lithium ion batteries, the sort you have
in your laptop, manage 1.8 kilowatts per kilo. That's 72 times more
bang per gram. Do you fancy carrying a battery 72 times heavier than
the one you have at the moment, especially if it's hotter than a sixty
watt light bulb?
Just not enough power. But then if I could have a 100 lb. battery that
would run for a decade without a recharge, I could find ways to use it.
It might be good to keep in the car and use to run things, especially when
camping or otherwise far from a plug. That said, how much would that
thing cost me?!
