Brunton Hydrogen Reactor
At CES, nothing is sexier than “high science.” That’s how Brunton markets its Hydrogen Reactor, a CES Innovations award winner. You plug in the Hydrocore fuel cylinder (about $20 each), which is the hydrogen part of this, and the Reactor sucks oxygen out of the air (at least that’s free) and the fuel-cell reaction creates electricity which is passed along via USB port to whatever you’ve got on the other end of the cable: smartphones, tablets, rechargeable lights, portable game consoles, to name just a few. Each fuel cylinder has “more power than a fistful of AA batteries,” according to Brunton. Price: $170. Priceless: impressing the impressionable.
