Alt fuels... & a Good stock pick

They're so efficient they don't need insulation!!

....I don't write this stuff....I just report it!

Whats the point of the system being efficient, & no insulation on the air ducts? .

If you are heating the space which the air ducts pass through what is the point of insulation?

When did the zone get a 'Stop Global Warming Discussion Forum' ???

Im not complaining, just curious.

As I recall, oxygen is needed to support combustion regardless of which politcal party grows the corn or sugar. As the oxygen producing forests of Bra`-seel and the planet are being destroyed through combustion, will there be enough of the O2 to matter? Ooops, that may have sounded like a global warming comment... sorry.

A few days ago. Although it seems more a 'tout dicey stock tips and grip about corporate conspiracy forum'.

I used to work at a certain place in the UK that pumped at least 5 gallons of Tri- Chloro, Tri Fluoro Ethelene into the air every day (thats C2, Cl3, Fl3).

I calculated that it was the equivalent of a small city using underam deoderants before the propelents were outlawed.

There was a perpetual artificial "cloud" over our lab.

And the sad bit is... there was absolutely no need for it.

Unfortunately I could say nothing about it

So what you are telling me is that the earth is warming up because of us useing fule not that it is a cyclic event. answer me this question when the earth was in the ice age and nothing lived but bacteria did they cause the earth to warm up?

[sechichester]

I guess that it is a good thing that we have trees to fillter out the air and give us o2

I saw the movie 'who killed the electric car' .. i'm not sure if you can beleive anything that comes out of the GM horses mouth anymore .. they take many times longer than they say and take an eternity to make a decision.. (and they are very very oil oriented ) -- so , the volt

1) is too far off -- toyota has been making hybrid for years and will assuredly beat them to market for a plug in
2) does anybody trust GM anymore ?
3) it was a publicity stunt to appease the public that a solution is forthcoming!@

.............
Hybrids are making good progress, and with battery technology advancing the way it is, there's a renewing hope in electrics. It'll be interesting to see how GM's new Volt fairs in the market, and how it actually performs.[/QUOTE]

.... there's a renewing hope in electrics....

There is practically no hope for electrics; unless you are willing to scale down to cars that have a speed and range a fraction of what is possible with hydrocarbon fuels.

One factor is the electrical energy required for charging the battery. I have seen estimates for the UK that suggest the generating capacity would need to be increased around four to five times to make it possible to substitute electric propelled vehicles for hydrocarbon propelled. It is likely the increase needed in the US would be greater.

Another factor is the amount of material needed for batteries. Unless the energy density of batteries can be increased by several multiples there simply will not be enough of the materials available. Again it is a problem similar to the increase in generation capapcity; there would have to be an enormous increase in mining/refining capacity for the elements that go into a battery.

Hydrogen fuel cells are more or less the same; an enormous increase in electrical energy would be needed to generate the hydrogen and the rare earth elements (platinum and palaldium) are not abundant enough to replace IC vehicles on a one for one basis. In addition with hydrogen if the energy is coming from natural gas or a lquid hydrocarbon it is as efficient or more efficient to use that directly in the engine when all the efficiences between the energy source and the final use are combined.

There bottom line is that at the current rate of consumption there are no practical alternatives to petroleum products as an energy source. Ethanol is not an answer; if corn growing was expanded onto all the available land and the entire corn crop used for making ethanol it would supply maybe 10 to 15% of the US demand. And this does not even consider whether ethanol production is energy positive or negative.

Well with the battery cars you need to keep in mind that to make the battery and the car you need to burn as much fuel to make the cars and battery as we do now just driving and the car indusry won't just make one car they make tons of cars trucks so if we stay with what we have now and just make the engines more efficent then we will be burning less fule then we would if we stayed the same and tried to make battery opperated ones
