On Tuesday, my laptop battery died mid-sentence, mid-flight and I was screwed. I'm looking forward to the day when I will be able to just pop in a new methanol canister and keep going. I was thrilled to read today that (when the fuel cell technology becomes available sometime in 2009) the TSA won't stop me from doing just that.
The ruling helps clear the way for the industry and consumer acceptance. Fuel cells extract electrons from a reaction between methanol, ambient oxygen, and a catalytic membrane. Fuel cell makers hope to replace lithium-ion batteries as a power source in portable electronics. One advantage: no recharging time. Refueling a fuel cell only requires popping in a new fuel canister. A universal charger made from a fuel cell can charge notebooks, phones, MP3 players, and other devices, cutting down the number of chargers travelers have to carry.
So I should be good to go. As long as I don't try to carry one through a metal detector inside my shoes, that is.
