We really need more research to be done on fusion power (and the means to distribute this power), and getting it to the point where it not only has a positive efficiency (duh), but is also economically viable. I view that as the key to the energy needs of the future. It would allow for clean-running electric car, and just in general, electricity that does not require the burning of fossil fuels. Nature locked up that carbon dioxide millions of years ago, and we're letting it all out again.

Say what you want - but the real world numbers of Honda Insight owners show them crossing 60mpg easily. I've seen it firsthand - so your theory holds no water.

I'm not a hybrid supporter, but come one, this guy just totally destroyed your "evidence."

(START RANT) Don't beleive hybrids are a scam? looking for "50 miles per gallon" KEEP LOOKING! Read these links, they note the revised gov testing procedures that fit todays driving habbits. They also show that no one gets 50MPG in a toyota prius. The prius has been given a 30% reduction in its MPG by the gov, this will be reflected on next years window stickers. Now factor in the added cost of a hybrid and you will see your better off with any "normal vehicle" there is no benefit to a prius except to pretend your doing the right thing and make toyota and all these other scammers huge piles of cash.

So the other arguement is that your "doing it for the environment and for the future of your children and the planet earth" thats great but as you know these cars have more batteries than standard cars (needed to hold the hybrids charge). These batteries need to be replaced every so many years depending on miles driven (at a cost of last time i looked $4000 dollars by the way, further setting you in the hole tword any artificial hybrid savings) so what happens to the old batteries? old batteries in a junkyard are far worse for the environment than a little filtered out carbon gas, the long term effect is polluting the ground for hundreds or even thousands of years. Cars of today put out nearly zip compared to even the cars of the 90's let alone those of the 70's. And i have said it before here but i will say it again the methane levels in cows farts deplete the ozone layer at a faster rate than current carbon levels of auto's do, so untill cows stop farting stop complaining about cars killing your environment. Also remember the ozone layer is in better shape than it was a few years ago and it continues to rebuild itself.

One more point i would like to make in this rant, a few years ago people were worried about "Global freezing" then suddenly that was aborted for "Global Warming", (big shot out to Al Gore, we wouldn't be talking right now if it wasn't for him because remember according to his ramblings he invented the internet ) The point is we are making this stuff up as we go along without enough research. For every scientist who says wine is bad there is one who says its great for you! Untill we have enough facts to really make a valid point why must we be so against those who choose to buy hummers, suburbans and tahoes? One day we will do something that pisses off mother earth and we will get shaken off like a bunch of fleas on a dog, or like the dinosaurs that as powerful and strong as they were got wipped out one day to put it into more realistic terms. Life is about survival of the fittest and this earth is much more fit than we are, when our times up trust me we will know it! (END RANT)

Interested in your thoughts and replies! (even if you own a hybrid)

That's not true actually. Old batteries can be recycled...that is if anyone ever had to replace them. Toyota has had hybrid cars now for 10 years and has yet to replace any of the batteries in any of them from what I've read.

I'll be quite happy to look at hybrids when one's built for someone my size - something I don't expect for some years to come. Currently the Highlander is the only vehicle that comes close. I'd switch right now if there was a hybrid version of my Sequoia.

FYI-You'd fit in a Scion xb just fine. I have a friend who is 6'7" and he has plenty of headroom in that vehicle. He's over 280lbs too.

I will say most that buy hybrids shouldn't be.

I will also say I know a couple that saved a lot going from an SUV to a hybrid. "go figure"

I know of one that commuted 100+ miles a day that noticed a big savings and that is understood.

The HF? Honda may have been an equal but cheaper, but the hybrid was more 'modern'.

I have forsaken V8's for now as I get better performance from my I4 that could be an I6 if I wanted to do a swap. My balance is close to 50/50. My 1966 and 1988 Mustang GT's were nose heavy.

Oh BTW that I6 was capable of beating a Hayabusa in the 1/4 mile and be streetable. There are a few fake vids of this original accomplishment though. I believe it turned an 8 sec 1/4.

There is now a kit in the works to give my car that same powerplant and it's AWD.

It's pretty easy to get 400RWHP out of that engine with a chip change....800RWHP is not unusual. With big bank 1000RWHP. I would never spend what that kit is going to cost, but if I made 7 figures+ a year I just might and see what it would do about 600lbs less curb weight.

All that said...my 2.4 in good shape I4 get 17 city, maybe near mid 20's highway. I drive a bit on the insane side.

I know guys in vettes that do way way better than me on the highway...but probably sipping tea with a pinky up.

We have the lowest fuel cost in all of the civilized world (I believe I know europe and japan is more money)...if fuel went to $5 a gallon (and it may here)...I'd be buying.

There is an interesting Playboy article this month about Pickens. He states finding the oil is not the answer, the world can only produce X amount of oil in any period. If the supply were to double it wouldn't help if the demand did.

What about the batteries when the cars are junked or replaced? They contain heavy metals I believe.

I love how hybrids (specifically Prius) are NOT designed the best efficiency, they're designed to make you THINK they do.

They point design them so they're extremely efficient at the speed used to report the gas mileage number, but don't perform as well at other speeds. If they did a better multi-point design they could be more efficient overall, though their highway mileage number would be lower.

The energy density (and as a result weight and size) of batteries is whats holding hybrid and full electric technology back.

The real question is, when we go full electric, will we be able to produce clean enough energy at the power plant level to actually be of benefit. We need more wind / hydro / solar / geothermal / nuclear power to compensate for the enormous energy demand via electricity that is ahead.

The off-peak energy from the power plants at night (when most people would be charging their cars) would be enough for a lot of cars, and even still, inter combustion engines put out 2x the CO than a coal-burning power plant. I agree though, we need more nuclear power plants, and a better way to use solar energy.

I've driven a Prius for the past 15 months. Generally I average 55 MPG in the summer and 45-50 MPG in the winter. (My personal best is 59.7 MPG over 540 miles.) If the outside temperature drops below 0F, however, the average drops to about 40 MPG.

Why is that? Does the electric motor become that less efficient when cold, or the batteries?

You'd be surprised. I fit very comfortably in my 2DR cobalt, though getting a child seat in and out would be a bitch. (I'm 6' 4" and 270)

I think it's harder for the batteries to hold a charge when they're cold. But the main reason for the decrease in fuel economy is that the gas engine has to keep running to remain hot enough for the heat to work. The only experience I've had with really cold weather was last winter when during several morning commutes the temperature was like -10F.

Buying a hybrid sends a message that people are interested in alternative forms of vehicles and fuels. That's something we desperately need to do with global warming becoming an issue (and it IS real, if you don't believe anyone here consult a local professor and they will be happy to prove it to you). At the very least, buying a hybrid is a statement that you care about these issues and wish that manufacturers pay more attention to these issues. Everyone needs to do their part in this huge global issue.

The issue for hybrids is fuel efficiency as we won't have oil forever. Considering that vehicles produce only 2% of the CO2 attributed to global warming, they aren't exactly the front runner for solving that problem - deforestation is 10x the problem at 20%. Coal burning power plants are the major contributer of CO2 when it comes to burning fossil fuels.

If people want to get hybrids because they think they're fixing the environment then that's fine, but they really aren't helping that much. What they are helping with is giving us more time with what oil we have left until we can find an alternative fuel source that is renewable.

we can, but no one wants it. also, if you took out the batteries and electric motor and other hybrid gubbins, you'd end up with higher mileage.

VW's answer to Hybrids

thats what Germany can do....lets see how america measures up. this baby might only have about 80hp, but it has wads of torque, nice for highway cruising. sure, its small, but with a mileage of 78MPG, who cares?

I have an '06 Civic Hybrid. I got 51.8 mpg when I filled up last time. This was the best I've ever gotten with it. Nearly all highway miles. I've heard the Prius really shines in city driving while the Civic does its best on the highway. Btw, there really is a learning curve as to how best to drive these kinds of cars. I'm not surprised that the government number would be significantly lower.

thats not an answer, its like a geo metro, the prius has the interior space of a camry. people like it because its size is practical.

http://www.usatoday.com/money/consumer/autos/mareview/mauto497.htm
a few quotes, theres plenty more bad but i'd have to copy the whole article btw the geo metro had very mileage too its not magic, make it tiny and lose weight.

"One way to cut fuel consumption is to eliminate the weight and power drain of accessories. So the 3L Lupo had no air conditioning, no power steering, no anything. You can add such options, but there'd go your three-liter claim.

And the car seemed low-quality for the $3,000 premium price its fuel-sipping hardware commands.

Not only did the seats turn torturous after about 90 minutes, a cup holder came apart in the first 10 miles. The economy-enhancing, easy-rolling tires and lightweight suspension transmitted not just noise but a roar to the passenger compartment on cobblestones, bricks and rough asphalt. "


"What's hard to overlook is the transmission. It's the key hardware that makes Lupo go so far on so little fuel. But even a fuel-economy zealot would have trouble being charitable.

To work its magic, the transmission seeks the highest gear ratio that the engine can handle without stalling, resulting in acceleration so sluggish it almost can't claim to be acceleration at all. It'll cruise 80 miles an hour all day. But ask it to change speeds and oh, woe. "

They as in auto manufacturers
I've posted an article previously how they moved a off the lot Ford explorer from 20 MPG to near 40 MPG using off the shelf technology available today for not that much money.
Which would be driven down a lot cheaper by simple economies of scale

low temperatures are unfavorable for a electrochemical cell reaction. and, assuming the entropy of the reaction is negative, a lower temperature reduces entropy, free energy, and the ability of the reaction to occur spontaneously. chemistry FTW
