Toshiba to Demo New Fuel Cell MP3 Players
virgil_disgr4ce tells us The Register is reporting that Toshiba recently unveiled a fuel cell based mp3 player. The pump-less fuel cell technology was first discussed about a year ago but Toshiba said not to expect the fuel cell players to hit the market any time soon. Toshiba, however, does hope that the players running off the fuel cell prototypes, and their methanol cartridges, will get their public debut at CEATEC JAPAN 2005.
Has anyone else here ever had exposure to 99.5% methanol? Nasty stuff. Toxic, and readily absorbed through the skin. I really can't imagine this being approved by any governmental agency. How about flying on an airplane with 150 or 200 methanol powered fuel cells? No thanks.
"The batteries double as a stinkbomb"
Maybe it's just a throwaway remark, but there is still a widespread perception that methane stinks.
Of course, it don't. The vile odour present in the domestic natural gas supply is due to the deliberate addition of a stenching agent such as an ethyl mercaptan. Of course, the purpose of the stenching agent is to alert people to the presence of uncombusted gas.
T&K.

LOL! If someone needs an econ course it's you!
A Duracell Ultra AA alkaline battery can be bought for about $1. It delivers 2.3 watt-hours. The power company charges something like 10 cents per kilowatt-hour. For $1 you get 10 kilowatt-hours from an outlet- as much as you get from 4300 Duracell Ultras. From an outlet, 2.3 watt hours costs about 1/50 of a cent. On the scale that we're talking about, that certainly is "cheap to the point of being free." We're not talking about recharging a Prius. Even considering recharge inefficiencies, you'll be lucky if you manage to use a penny's worth of electricity over the lifetime of an AA rechargeable battery. Just leaving the recharger's wall-wart plugged in wastes more electricity than the rechargeable gets.
Per watt-hour, the energy costs associated with batteries- rechargeable or not- are several orders of magnitude greater than those of the cost of a comparable amount of electricity considered purely as a commodity. You're not really paying for the electricity with batteries so much as the portability and convenience. And with rechargeables, most of the cost of operation comes from degradation to the battery structure over repeated charge/discharge cycles. (Plus the environmental load from the cadmium when people don't recycle NiCads.) The cost of the recharge current itself is the most negligible factor as the GP correctly pointed out.
