  1. Don't forget about wet pants on NEC Unveils Methanol-Fueled Laptop · · Score: 1

    recombining hydrogen with oxygen produces water. Where does it go???

  2. Re:Li-ion cars on Building Longer-Lived Fuel-Cell Stacks · · Score: 1
    Sorry, I don't have the info on the prototype Li-Ion car but you can look here:

    and the follow-up to that write-up here:

    autonomous everything!

  3. Fuel cells are a joke on Building Longer-Lived Fuel-Cell Stacks · · Score: 1
    Why donâ(TM)t we focus on new chemical battery technology or focus on reducing the cost of existing Li-Ion technology? A prototype Li-Ion battery-powered car costs 1/4 as much, travels 3 times as far (350 miles) and weighs less than todayâ(TM)s typical fuel cell powered car and can be effectively produced TODAY. Moreover, the infrastructure already exists â" itâ(TM)s called your 50A 220V circuit in your garage or basement. Quick charging systems can be placed at gas stations WITHOUT REQUIRING A WHOLE NEW DAMN DISTRIBUTION INFRASTRUCTURE. High power, quick charge, inductive charging systems can be utilized at home so you never have to physically âoeplugâ in your car. Oh, and you can toss about 2kWp of solar photovoltaic modules on your rooftop and you'll have enough juice to travel 30 miles every day - A TOTAL ZERO EMISSION SOURCE OF TRANSPORTATION.

    The govt is in bed with the oil coâ(TM)s. The oil coâ(TM)s wonâ(TM)t support an economy that only supports the utils. So inefficient, expensive, impractical, unrealizable fuel cells are the future!

    Autonomous everything!

  4. Re:20% leakage - at least! on Widespread Use of Hydrogen May Hurt Ozone Layer · · Score: 1

    20% IMO is very conservative. The cost required to create an efficient hydrogen transport infrastructure is TREMENDOUS. The cost to manufacture a long-distance pipeline that contains 90% of the hydrogen is unfathomable. Do you know how much material and labor has to go into a pipeline capable of containing even 80% of hydrogen??? It's not cheap. There is a cost meeting point of creating a super-redundant tranport mechanism and allowing "some" hydrogen to escape freely into the atmosphere. Economically speaking, we're probably looking at 25%+ of produced hydrogen escaping into the atmosphere. Otherwise the damn transport and fueling infrastructure will be cost-prohibitive (not that the hydrogen economy isn't already).

  5. heh? on More on Oregon and GPS-tracked Gas Taxes · · Score: 1

    Just raise the gas tax. What the hell is the point in sending out a bill every month? The admin stuff alone will cost a fortune. Besides, this will give zero incentive for buying fuel efficient vehicles. Bush would love that.
