Government mandates only stifle and stagnate this process. Thus we achieve two ends with the only downside felt by the Saudis, Hugo Chavez, and a few other nasties. Sounds like a plan to me. Dan Mc |

We are talking "fleet average," not the mileage of every truck. There are a nontrivial number of trucks, and 4-6 MPG is the rule rather than the exception. It takes a lot of econoboxes to counterbalance that. The fleet haulers are not currently or planned on future inclusion into the overall transportation fleet. You use common sense. Those that can do so, could use the hybrids. Those that really need the larger vans and SUVs could still use them and the trucks could still remain. IOW we use what we need , not what we think we'd like. That's not the way the American system works. The only person entitled to It sure is. People have to learn to make the proper decision. make a decision as to what vehicle they need to purchase is the buyer. Not you, not me, not the government, and certainly not some enviro-wacko who knows nothing about the buyer's needs. And I said no differently. snip for brevity Let me guess: you were wearing the seat belt, and the SUV driver wasn't? Both were wearing seatbelts. That's not an indictment of the SUV, but of the idiot who wasn't wearing his Wasn't meant to be. It was to show the smaller car is not always the looser. seat belt. (I'm a former paramedic. There are a few things I get rabid about, and seat belts top the list.) A hybrid SUV might be more fuel efficient than its conventional counterpart. Then again, it might not be. I looked at the hybrid version of my SUV when I was first considering buying it, but ruled it out for one simple reason: 95% of my driving is at highway speed, where a hybrid provides no benefit. The extra purchase cost, plus the battery replacement at 100K miles (and yes, I do keep vehicles past that point), far outweighed any possible fuel savings given my driving needs. As a personal opinion and a far amount of time reading specs I doubt many if any of the hybrid SUVs really provide any economic, or CO2 advantage over their lifetimes. If that's the case, why is government raising the alarm? See, for example, http://www.npr.org/templates/story/s...toryId=7431198 . That's not the government, two the government didn't raise an alarm and three the woman who manages the EPA's Energy Star program says: "She says that even though fluorescent bulbs contain mercury, using them contributes less mercury to the environment than using regular incandescent bulbs. That's because they use less electricity — and coal-fired power plants are the biggest source of mercury emissions in the air." As for the electric car, let me once again use those two magic words: "mission profile". I'll consider one when I can get one that will go 400 No one said use the electric car for long trips hauling heavy loads. If that's the only car I have, I have no choice. I make those trips, so I have to have a vehicle that will do the job. Or are you suggesting that I be forced to buy two cars, one for the few local trips I make and one for the missions the first won't handle? I also allowed for that in the original note. "We drive what we need to drive". IOW if you need an SUV you drive an SUV, if you need a truck, you drive one, but those who don't absolutely need one should take the responsibility and drive what they need, not what they would like. The average trip made by cars is short and typically round trip to work, or in to see the kids play what ever sport. Car pooling could take care of a lot this. The average person's average trip, in a city, maybe. Ask someone living in a small rural town what their average trip is. Again you are ignoring what I said. People should take responsibility and drive what they need. The electric car is nothing more than another form of transportation and a short range one at that. Why would I expect some one living in a rural town to drive one 30 to 40 miles to work. I used to drive 65 miles one way an for a guy who hates to get up early that was torture. What did we do? We sold our home in the country and moved about 60 miles closer to a rural subdivision. This kind of fallacious generalization is why government regulation of what people buy is simply wrong. I did not make that kind of generalization, you read it into what I said. However for those that need the extra room and load capacity they could still have it. I reiterate, FLEET AVERAGE does not mean every car and tuck has to get that mileage. It's expected that all of them averaged together would get that. Big difference. That does nothing for those of us who aren't average. Driving up the fleet Those of us who aren't average ...aren't average. IOW as I said before we drive what we need to drive (not what every one else does. If you have 6 kids you don't try to haul them around in a Corvette. average will require that the vehicles that will handle my mission be unavailable, or else emasculated to the point they're unsafe. Even the econoboxes are safer than the cars of old. This is the typical "all or nothing" argument against better mileage or conservation. When it comes to the cars on the road, most of us don't need a big pickup truck, monster SUV or 5,000# luxury car. I don't either. My small SUV does the job. However, I REFUSE to try to tell someone else what they need or don't need. I cannot make that judgment for them. They can only do that for themselves. The alternative is central planning, comrade. No one in this thread has either. Of course the LEDs are far preferable over CFLs, but they are currently very expensive. Give 'em a couple years and they just might be on par with today's CFL, but far more efficient and almost indefinite life with very little heat given off and no starter required. And if they do that, I'll happily switch. (Assuming they don't flicker annoyingly when fed 60 Hz AC.) That's the real key to doing the environmentally correct thing: Make it economically justifiable, too. I don't mean artificially raising the cost through taxation or anything like that. (The same arguments that justify doing that in other circumstances can be used to justify raising the cost of fuel for your Debonair to $10 a gallon. How much does it burn an hour?) I mean make it save real money. The greatest impact on safety would be getting the public to quit accepting a yearly highway death toll of between 40 and 50,000 as acceptable. No argument from me on this one. Maybe the biggest at present would be to build a jamming device to prevent cell phones being used while the car is in motion and education. Got a 2-meter rig in your car, OM? I do, and have had ever since I owned a 2-meter and 440 car. (Well, sometimes it was just 440, but you get the idea.) Just because some people can't talk and drive doesn't mean everyone can't. Neglecting the ability to talk and walk, er... drive:-)) at the same time there's a big difference between using a mike and holding a cell phone up beside your face blocking the entire view from one side. Today there seems to be an element in society that fights any change to improve things. When the suggested improvement is a drastic change in the way we live, and where we live, and how we live, you bet your ass you're going to get resistance, at least here in our free society. You see, the government isn't supposed to treat us like the Chinese government treats its people, but that's exactly what the enviro-wackos are calling for. Nothing comes without some kind of cost including "business as usual" which probably has the highest long term cost of any option. That has yet to be demonstrated to the satisfaction of a lot of Americans. If you're so keen on saving the planet, why haven't you junked your Debonair and bought something smaller? I fly it far less and save energy in many other areas so in essence I've cut my carbon foot print drastically. As I said before (in another thread), if I get back to flying any where near what I used to the Deb is going to get a different engine that uses far less fuel. BUT even at its present 14 GPH, flying it to Denver uses less overall energy than does driving my car (I'd not be driving the Prius that far with the amount of stuff I haul with meg) Roger Halstead (K8RI & ARRL life member) (N833R, S# CD-2 Worlds oldest Debonair) www.rogerhalstead.com |

There was a hell of a scramble to get the fossil fuel plants online. The big problem with wind is that it is not constant, and unpredictably so. So Like here in lower Michigan. We have almost the ideal average wind speed, but unless close to one of the lake shores it's usually way too fast or calm. However for the individual home owner there are variations of the Savionus (sp?) S-rotor that work well out in the open. Here we're surrounded by trees on three sides and putting a generator high enough to clear the trees would be impractical from an economic viability. Out on the farm mixed in with active and passive solar they'd probably give us an independent level from the mains of around 75% with enough excess to actually make money. Not much, but at least come out on the positive side of the ledger. I'd like to experiment with passive solar water heating, supplemented with "on demand" hot water heaters for the kitchen and shower.. I cold add a green house to the south side of the shop and probably heat enough water the cut the heating bills for the house and shop in half. With a large enough reserve we *might* be able to heat enough water to supplement the gas fired forced air heat, but I'm afraid for electricity we'd come out way on the short side. As I've mentioned before, I was given a figure by a consultant of $50,000 to get about that 75% and a payback of over 20 years. Electric rates are currently around 10 cents per KWH and gas is relatively inexpensive as well. Nor do we receive any subsidies compared to California where rates are near 40 cents at peak demand, they receive about a 50% subsidy and have far more sunlight which also happens to be more direct. you must have conventional backup ready to go. So all you save is fuel costs at a huge capital expense. A gigawatt of wind power will not replace a gigawatt of coal, or nuclear power. -ash Cthulhu in 2008! Vote the greater evil.

The big problem with wind is that it is not constant, and unpredictably so. So you must have conventional backup ready to go. So all you save is fuel costs at a huge capital expense. A gigawatt of wind power will not replace a gigawatt of coal, or nuclear power. There are various ways to "flywheel" wind power. Also, wind becomes more reliable when the generating field becomes large enough to span several states. The wind's blowing somewhere in the Midwest. Finally, no one is proposing that wind and solar can be the sole sources of electricity with present technology. The goal for now should be increasing their supplementary role in power generation, while developing uses for them in the direct production of fuels. |
