You're aware that IC engines in cars are the least efficient use of fossil fuels right?
Why do you say that? Please justify your claim.
Because excess heat indicates inefficiency. I'm sure MM will dispute that but if you have to have a cooling system and radiator that indicates that you are dispursing HEAT which is POWER!
Here you go buddy and you'll even notice that I didn't cherrypick a sire that echos my opinion. If we could build cars that get 100 MPH run clean and weigh more than 400 pounds(i.e. safe) then I am all for it. Even though I was highly against new drilling I would even relent on that issue(with more refinery capacity).
you want to go back to 2 cycle style engines?Hey MM could we have valves that go directly into the cylinder? So say fi]or eaxmple the oiston is driven down and at the bottome of the sroke there is an open hole that the exhaust escapes from. The then piston then seals that point by passing it and has an intake further up the stroke and then compresses. no valves nessacery. I guess jkind of like the Wnckle Rotery but could it be modified ti work with a more conventional IC engine?
The problem with electric cars isn't the effiency of the motor, its keeping the batteries charged. Having to recharge for hours after just a couple of hours driving isn't going to work for most people, especially for people that can only afford or want one car. It would make driving long distances infeasible. Simply put if electric cars were more effient, more practical, and competitively priced, they already would of replaced IC vehicles.
Hybrids are lot more practical for that purpose, which is why they are starting to sell.

Radical liberal environmentalists don't care if you can't get where you need to go. They want to control your life and you will just shut up and take it! You will drive your electric car and like it mister!
what if you only have one?Like I said if you replace just ONE of your houshold cars with plug in electric we could eliminate our dependency on oil. You can keep your truck AND your boat I don't much give a shit if you do but if you replace your COMMUTER car with a plug in electric you can save money AND oil. Fully 80% of dialy commuters can use a plug in electric for their daily commute so what is your problem with that.
I just don't see the HYSTERIA of not having a car that you can drive across the country. MOST people never drive more than 300 miles from home. EVER!
TOO often, discussions of alternative energy take place in an alternative universe where prices do not matter," Popular Mechanics reports.
To remedy that, the magazine set out to figure out what it would cost to drive from New York to California using seven types of fuel.
It was not exactly an apples-to-apples comparison. Because there was not one automobile that could handle all types of fuel, the magazine tried to match the cars as closely as possible in size and weight. And the price it used for gasoline - $2.34 a gallon - is about 20 percent less than most people are now paying at the pump.
Still, the results in the cover article by Mike Allen are intriguing and surprising. The cheapest fuel was electricity. About one ton of coal would be needed to produce the requisite energy. Cost to drive coast to coast: $60. Using compressed natural gas would set a driver back $110. And biodiesel, made of used vegetable oil in the magazine's example, would cost $231.
Gasoline, as it turns out, figured in the middle of the pack. It would take 4.5 barrels of crude oil to produce the 91 gallons of gasoline necessary to get a Honda Civic coast to coast. The cost would be $213.
On the high end were E85/ethanol, a mixture of 85 percent ethanol and 15 percent gasoline, at $425, and M85/methanol, 85 percent methanol and 15 percent gasoline, at $619. And then there was hydrogen. It would require 16,000 cubic feet of hydrogen to power General Motors' Hy-wire concept car: $804.
Actually Heat does represent lost energy. A Carnot cycle engine, the standard for IC, depends on a temperature difference. Unfortunately the input temperature for automobiles is moderately high, on an absolute scale, even when water freezes. This places a theoretical limit on the possible efficiency of a Carnot cycle combustion. Generally in any energy balance equation the "heat" term is used for lost energy, such that withComing back to this for a second: You seem to equate heat with ineffeciency. Nothing could be further from the truth.
If the Q-dots deliver on the promise of super cheaply manufactured solar cells at about 40% efficiency, putting 5 kw of these on the roof of one's home would not only fuel and electric car, but also power the home, and deliver extra on the grid at the time of highest power use.
Combine that with what you have pointed out concerning the efficiencies of the power plants versus ICEs, and the electric vehicle looks like a winner as soon as we have adaquete electrical storage systems.
Another point. The present SUVs, pickups, and vans are prime candidates for retrofittining to batteries or super caps. I have a stretch 350 Ford van. It has acres of room underneath between the frame for storage of the batteries. Remove the engine, drive line, and the entrails of the third member, and the vehicle has shed over a thousand pounds. For that amount of weight, I could put in about seven of the Eestor units which would give me a range of about 700 miles.
