As for the math needed to give a first approximation of the EV range for the Volt, you act like there is some big mystery. There isn’t. As you should for every EV using a Li-ion battery pack, take the battery back size in kWh. Multiply by .7. Divide by 250.

——————————————————————————————————————————–

Where did you get the 250 figure? Both the Rav4-EV and the EV1 got 6 miles per kWh at 30 MPH. The Rav4-EV got 3 miles per kWh at 60MPH where the EV1 got 4 miles per kWh because of better aerodynamics. Most conversions get 1.5 to 2 miles per kWh because of the poor quality of parts available and expense of the better parts in lots of one.

The figure they are basing their calculations on is 5 miles per kWh for the Volt. Although the Volt will have a 16kWh battery, only 8kWh is usable in EV mode. I suspect GM is figuring a 50% freeway/ 50% city street average to get this and hoping the Volt will do as well as the EV1 on the freeway. The way you drive will infuence this so, as with all cars, your range may vary.

As the ice cores that have been taken… dramatic temp fluctuations were precursors to rapid global cooling. As per global ends, I seem to recall a cheery someone who gave like dire predictions of running out of everything, a 19th century dreary fellow actually. Bees are now at a holding pattern. Lead was banned in fuel but… Coal fired plants dump radiation, lead… so where is the push for real large energy sources like fusion, fission and yes solar. Like I said, $ and the people who depend on carbon fuels will not quietly pull the trigger or walk away.

I’m all for Das Volt by Gov. Motors and others but I still find the notion that the dramatic dynamic forces of a planet and the Sun, (forgot that the Sun is doing some strange NO sunspot activity ie chilly World), that humanity is anything more than a pin prick. WE are well able to destroy the economic infrastructure with fear and dictatorial Orwellian “management”. yes we can.

MuddyRoverRob—– the whys of Fahrenheit have some logic and that is just a GOOGLE away. Living/surviving in a tiny temperate zone of Centigrade does not, for humans that is. 32º is manageable but 0º F is rightly a challenge. Have frostbite to prove that but that was but the puny human flesh! LOL!

Skynet is definately a tough nut to crack.. I finally got out to see the new movie on the weekend. It is certainly built for another movie… It was all right though.

A pint is ‘large’ and a glass is ’small’ I’m betting your bartender in Nelson simply didn’t have any pint glasses clean! (a nice town, my kids like a particular chocolate shop there)

I agree with Statik (#130) that I don’t want to get into a global warming discussion. For one thing, although I’m familiar with the basic arguments, I’m not an expert by any stretch, and I’m not qualitifed to argue about it. That means, I’m going with the opnion of the vast majority of the experts. Especially, since none of the counter-arguments that I’ve seen sound very convincing–at least to me. It is possible that they are wrong. However, personally, that’s not a risk I’m willing to take.

However, since you asked–yes, ice ages are regular occurrences. And, yes, things heat up in between ice ages. It’s a question of degree and how fast. And we are heating up extremely quickly in terms of historical global climate change. Also, usually, the carbon increase in the atmosphere happens as a result of the already naturally occuring global warming. (And intensifying the effects.) Here, it’s preceding, and causing the heating.

Also, we are straining at the ends of basically all our global resources. The glaciers around the north pole are getting smaller. We’re reaching peak oil. We’re running low on clean water. We’re eliminating the forests at a frightening rate. We’re overfishing the oceans. (The average size of tuna and sea bass has gone down considerably.) Mercury and other contaminants are showing up in fish. Lead is showing up in the soil in people’s gardens. The coral is dying. Frogs are dying right and left and no one can figure out why. Ditto for bees (and they’re actually a crucial part of our food chain). The American chestnut is endangered–and not because of logging because they’re dying. How can all of this not have an effect on the climate? Or a long term effect on human health?
