Light Bulb Replacements

Posted by Hemos on from the fixing-new-ones dept.

LoveOO writes Boston.com has a story about three companies which are trying to replace the Light bulb. I say it's about time and what about hydrogen powered vehicles? Two things that annoy me are filling the gas tank and changing light bulbs. It's time we did alot less of both."

    Filling the gas tank is so much worse than filling the hydrogen tank?

    In principle, you could drive your hydrogen-powered car home at night, filling the exhaust tank with water. You could then plug your car in to an electrical outlet, and the water would be electrolyzed to hydrogen and oxygen overnight, filling your fuel tank. Depending on how fast the electrolysis occurred, it probably wouldn't eliminate the need for filling the tank, but fillups could be less frequent under city driving.

  2. So where will you get the Hydrogen? by BobBoring · · Score: 1, Offtopic

    Hmm... Where will we get the hydrogen for all those green hydrogen fueled cars? Nuclear power plants? Coal fired powered power plants? Those solutions for generating hydrogen are potentially worse than the continued use of diesel or gasoline fuels.

    Wind power? Just look at the problems getting a pilot test done on the coast off Massachusetts. The Kennedy's are saying NIMBY to a commercial wind power generation project. Yes you can build them in the middle of the desert but then you have to build a power transmission line to get the product to the consumer. Due to the low density of the power the cost of building and maintaining the transmission lines needed to "add" windmill farms to the grid approaches the market value of the power generated.

    Same NIMBY and transmission issues with solar generation projects.

    Aqueous alcohol fuel cells look to be more realistic solution. You don't have to use as dry (water free) an alcohol as in direct combustion of the alcohol. Use of biomass generated methane gas and direct solar heating to power the grain fermentation units and distillation units would increase the energy density of the fuel. You flush a nice bit of biomass down your toilet every day so every major city has a ready supply. Plus recovery of the biomass from waste water via a closed loop tertiary water treatment system will provide additional drinking water for the city. Don't gag about drinking the treated sewage idea most likely if you like on a major river system and get your drinking water from that river you all ready do. You just have a lot less control over the quality of the water at the intake than you would with a closed system.

    quote: "at least we'd be using our own natural gas. The US has so much, it would be considered the "OPEC" of natural gas."

    ... at least while congress is in session.

    I don't know, man. Using my own natural gas - sounds painful.

    Long time ago, I saw our Cocker Spaniel with a mouse in its mouth, and yes, I let it eat it. I understand that wolves feed off mice when they can't get anything else, so I cannot see the harm to a dog unless the mouse had got into some Warfarin or something.

    On the other hand, I don't understand the "how" of this dog ever catching a mouse -- this guy would pursue any prey barking and with floppy ears flapping: he was not big in the stealth department. Cats, however, are real killing machines. They are quiet and the "pounce" on their prey.
