New Butane powered fuel cell (a crowd funded startup)

[dnaylor]

Ok.. this could be quite useful assuming they reach the release dates etc... seems to have a lot of pluses according to spin and specs..

Size and weight looks good, the fact that your not tied to a specific company for the gas like the hydrogen fuel cells are and also the price looks competitive..

If you don't get too hungry (power wise) this should cover recharge needs for at least a few days or more in the bush on a single tank of gas, you may still want to use a battery bank for backup storage as some electronics are finicky on recharging..

I'm really considering pre ordering one...

Why on vapourware? If the technology becomes mature, there'd be a flood of them on the market and potentially at better prices.
