Direct methanol fuel cells are typically minimally the size of your fridge, and run at several 100 degrees Celsius (volume/surface ratio requires for them to be of a minimal size to be able to run efficiently at such high temperatures.). Liquid methane is especially bad, since it requires cryogenic storage. Unlike higher alcanes, such as ethane, propane and butane. But, as methane, these still need fuel reforming, or a direct hydrocarbon cell, all of them hot, hot, hot. Direct methanol fuel cells, on the other hand, is very suitable for a wearable, because it uses a water/methanol mix as one electrode and air as the other electrode in a compact, RT electrochemical cell. -- Subscription/unsubscription/info requests: send e-mail with subject of "subscribe", "unsubscribe", or "info" toWear-Hard Mailing List Archive (searchable): http://wearables.blu.org please, Please, *PLEASE* don't subscribe through a forward/false domain
