EPA predicting 75mpg rule by 2030
Carmakers already concerned about tough new 35mpg fuel economy standards set to roll in by 2020 now have something else to worry about with the announcement today by an EPA official that passenger cars and light
trucks may have to average 75mpg by 2030. The latest statement follows a previous announcement from the scientific community that world oil usage could rise to 120 million barrels a day by the same 2030 cutoff date - up from 85 million barrels at current levels.
Speaking at the SAE International World Congress today, the U.S.’ director of the Office of Transportation and Air Quality, Margo Oge, said a 75mpg target is necessary to meet a widely backed scientific-community proposal to cut greenhouse gas emissions by 50 to 80% by 2050.
"There are a lot of strategies you need to consider - both engines and fuels," she explained during an interview with
The Detroit News. "Carmakers need to be thinking of those investments for the long term basis," beyond the current 35mpg CAFE energy bill.
America’s transportation sector accounts for two thirds of U.S. oil use and a third of its greenhouse gas emissions, so any improvements in fuel economy standards will have a major effect on the country’s dependence on oil and pollution levels.
As for the current 35mpg standard, the National Highway Traffic Safety Administration is expected to release its proposal for 2010-2015 interim fuel economy increases as soon as next week.

I'm almost 100% sure that by then they will have quick-charging batteries, which would solve all of these problems in one fell stroke.
I know, there are those of you who say that electric power just shifts the problem, and then Chris will set you straight.
I for one would buy an electric Mustang GT tomorrow if it had a 300 mile range, and the equivalent acceleration, a certain mass and safety, and a battery that charged at a high-voltage filling station outlet in the same time, or even twice the time of a fuel fillup.

Well atleast you can produce electricity from solar/wind/hydro etc --- can't really convert sunlight to petroleum :)
But yeah, I definitely agree w/ Gus, if I could buy an electric car w/ 200-300 mile range I'd be the first in line to buy one... however the current vehicles which get 30-40 miles per charge are useless to 90% of the people...

yeah I really think that 35 mpg by 2020 is a bit of a push, mostly because of the turnaround time on the technologies needed for this, but 2030 at 75mpg,... all I've got to say is... you'd better put that in writing now. after the auto industry goes for 35 mpg by 2020, 75 by 2030 is nothing.
gus, you know me all too well. by 2030 i'd expect most commuter vehicles to be electric battery type, and only large sedans to have an ICE for "long travel recharge". full-on-frame pickups for the public will almost certainly be obsolete. people who need to "haul" will have crossovers and el-camino types, and again, crossover is just a fancy way of saying a hatchback variant of a midsized or full sized sedan.
the kind of quick charge that you're talking about,.. is something that I dont expect to see very quickly. you're putting energy into the battery. the battery takes 8 hours of driving to discharge but you're going to charge it in 1 or 2 minutes? batteries have an internal resistance, meaning that when electricity flows through them (the purpose of the battery), they heat up. when you charge a battery, the process still takes place. who knows... we may still have liquid cooling systems on our future cars, but for the batter instead of the engine block.

when it comes to electrical sources, it must be stated that the "green" power alternatives aren't that great. solar is about 20% efficient. I think the latest estimate was that all of texas would have to be paved in solar power to power the entire nation. you're actually better off reflecting a large area of sunlight into a small focused beam used to boil water (then the steam turns a turbine like in almost every other power plant). check it out: Solar heliostatic power. Wind is good so long as you can find "good wind" ie: constant, or at least constantly blowing wind. gear boxes can address the speed. hydro is the big "green" power but you get a really big problem with displacing wild life, loss of land mass, and many other issues that are giving hydro a really bad name.
if you want a good list of green tech, think: geothermal, wind currents, and tidal flows. tidal power could become a huge thing considering such a huge percentage of the earths population lives within 100 miles of coastal areas. tidal "winds" are like normal wind but if you've ever tried to walk through a wading pool, you'll understand just how much kinetic energy can be extracted from water as opposed to air.

I see Ford is going to employ some diesel technology on a gasoline engine using direct injection and sequential turbochargers, but that's nothing more than a 3 year old Mazda engine with a few upgrades and really not a step forward and GM Volt may be vaporware or it might not. Too early to call it.
Good thing we can depend on Toyota, Honda, MB, Audi and VW for advances in engine technology.

sorry for the long quote...but i was thinking, is there a plausable way for the heat (see energy) generated by the batteries as they charge to be able to be harnessed? just a thought mind, seeing as Chris is the one with the finger on the button on this topic.
