Bye bye Democrat Party.
I'd like to see more R&D with hydrogen fuel cells, (e.g., proton exchange
membrane fuel cells). I built a working Solar / Hydrogen powered model last year (from a kit). It worked well; had a photovoltaic panel that produced DC which was used for electrolysis of water. The water and the resultant H and O gasses were all stored in a baffled tank (attached to car). The H and O gasses were fed to the fuel cell, which used them to produce (1) electricty to power the car, and (2) liquid water, which was dumped back into the storage tank to be reused. Naturally, I did not fail to consider the possibilities of using this technology at sea, either for utilities on board, or for propulsion (for docking purposes only!); hence, this is a sailing post. So why didn't the car use just the solar panel? (I can hear some wondering) The solar panel had to produce a minimum amount of H and O before the car could overcome its initial inertia (move). The output of the solar panel could generate enough H and O to keep an already car moving, but its electrical output alone could not get it moving from a stand still. Also, when the inevitable cloud passed overhead, the stored fuel allowed the car to keep moving (as long as the sun came back in a reasonable amount of time) The same tank holding the water also held the accumulating gasses, providing higher capacity for the start up and sunless time periods. It took about 5-10 minutes in the sun before it began to move. Then it ran and ran and ran, as long as the sun would shine (or in this case, until I got bored). It gave me some faith in the concept of fuel cells. Now, if we can ever get fusion to produce a better than 1 to 1 ratio . . .

The exhaust of today's auto is cleaner than the exhaust stacks of coal fired electricity plants ... Ohhhhh! So this means George Bush was wrong when he said full implementation of electric cars in the future will reduce auto related polution drastically. Actually, Bush (and environmentalists) ARE wrong about that. Yasee, electricity comes from dirty coal-burning plants. Most of the energy from the coal gets lost in the air or water as heat. Then more of it gets lost heating transmission lines that bring electricity to your car. Then more is lost converting that to DC, then to chemical energy in yer battery, then back to electricity and finally to mechanical energy, some of which is wasted dragging the heavy batteries around. These losses consume over 90% of the energy in the coal. Infernal g combustion is far more efficient, loosing only 70% or so. Reducing emissions of individual cars doesn't help if there are more and more cars. Ie if you reduce emissions by 50% but have twice as many cars you're right back where you started from - except that the 2x more people driving those 2x cars are also farting, taking dumps, heating their houses, et al. So, all of these "solutions" are really band aids covering up the real wound. Oh well, the Yellowstone eruption will take care of it .... (c: |

Speaking as a person who has made an embarrassing amount of money (that is, it would be embarassing if I had any shame) working on coal fired combustion control systems, you are full of baloney. I suggest starting out with a good high school level physics text, it appears you tried to skip ahead and missed a lot of the basics. Reducing emissions of individual cars doesn't help if there are more and more cars. Ie if you reduce emissions by 50% but have twice as many cars you're right back where you started from - except that the 2x more people driving those 2x cars are also farting, taking dumps, heating their houses, et al. But we're all still better off than if twice as many cars are putting out unreduced emissions. Basically, the idea that intelligent & responsible citizens can be complacent about the environment is disgusting & destructive. I hope you don't have kids to apologize to about your attitude. DSK |

... it appears you tried to skip ahead and missed a lot of the basics. You're right! CA had me take placement exams then made me skip over basic physics and chem. But tell me, where am I wrong? Why does the coal burning plant near me need water cooling if it's so efficient? What are the transmission losses getting power from (US 301 & Potomac River) into D.C., including voltage transformations? How efficient is a battery charger? A battery? A DC motor or an inverter plus an AC motor as the case may be? Reducing emissions of individual cars doesn't help if there are more and more cars.

But we're all still better off than if twice as many cars are putting out unreduced emissions. Are we? In 1966 a 'vette was $3500, a Cobra or XKE $5000, and a Ferrari a tad over $10K - all less than a years pay for a recent grad. Today? We have the same air, etc. quality we could have had by reducing population but an average 25 year old cannot have a Cobra or XKE, let alone a Ferrari. He's been forced to give up high performance cars, and a zillion other things, just so fools can have babies they cannot afford. Basically, the idea that intelligent & responsible citizens can be complacent about the environment is disgusting & destructive. I hope you don't have kids to apologize to about your attitude. Complacent? Hardly! I deem idiots who pop/father more than two kids disgusting and destructive, and ignorant to boot - ignorant as in "Du-uh, I just wanna keep the (pick one) safe for my 12 kids to enjoy, ka hilk ka hilk ..." |

Didn't study thermodynamics did you. Yet another telling post from the
pompous one. Cheers MC DSK wrote: Water cooling has nothing to do with "efficiency." If the plant were 100% efficient, it would still need some sort of outside heat sink to get over the enthalpy threshold.... |

OK, define "enthalpy" and give a brief description of how the concept applies to heat engines. DSK |

For years I worked on the contingency that my pay was a percent of decreased maintenance & fuel costs due to my work. Now how do you think I could afford that trawler, by screwing up & whining to Uncle Sam like an Enron exec? Sounds like you are a very effective BS artist .... Oh great. Next you'll tell me that we'd be better off had there been a nuclear war ... .... albeit ignorant and lacking ability to entertain new complex ideas. Worse yet ... You're another right wing nut case, aren't you? .... .... your over-active imagination has no factual basis. That's prolly why you flim flamed so much $$$ as a BS artist. Works like "magic" on some, but not your betters. |

What kind of boat do you sail, again? Vito wrote: Catalina 30 Good, at least some tiny bit of your post makes sense & is on topic. Vito wrote: Which means that electric cars make more pollution, they just do it out of town. No, electric cars cause less pollution overall because even the dirtiest fossil fuel electric generating plant is cleaner than car exhaust. You said to tell you when you were wrong, here's one more... getting to be a pretty long list, eh? Challenging the Crapton's batting average? DSK |
