About a kilowatt and 3/4 pound, so about 2bhp per pound. 200 brake horsepower for 100lb weight anyone? and no gearbox or clutch? No wonder that electric Lithium car at AC propulsion is gettin 0-60 times in under 4 seconds, and a 300 mile range... They beat the fuel cell cars on everything at the tests. www.acpropulsion.com There are two problems with elecric motor vehicles that would have to be overcome to make them viable. First problem would be that they really need some kind of backup power. If a conventional fuel vehicle (or indeed any fuel that can be quickly recharged) runs out of or low on fuel then it is a quick and simple job to put more in the tank. A battery powered vehicle would need some considerable time recharging - either at the side of the road or at a recharge point/"fuel" station. Forget to put the thing on charge last night? You're stuck in the morning. Power cut? Ditto. The occasional long journey? Forget it. Second problem is one of recharge logistics. Battery vehicles would represent a considerable advantage in towns and cities. Quiet and pollution free at the point of use. However, the majority of people living within large cities and towns do not have designated parking spaces, and most of it is on-street parking. Pavements would have to be dug up and publically accessible chargeing points installed to be able to recharge such a vehicle, along with a suitable payment mechanism. I can't see the LA taking too kindly to me stringing a cable across the pavement to my house! Even in areas with controlled parking zones there is no right to be able to park outside one's house, so the price of someone parking in "my" space, abandoning a car or even leaving a skip would be complete immobility for me. Visitors? Hmmm. I'd have a battery powered vehicle at a sensible price and with decent performance/range like a shot. But until these problems are solved, then it's not viable. -- Richard Sampson email me at richard at olifant d-ot co do-t uk |

This can be reduced by having smaller local power stations, the UK had them, using natural gas, using CHP to heat the local district. The indirect transmision losses involved in shovelling large numbers of loads of small amounts of fuel to thousands of small power stations all over the country are vastly greater than the transmission losses in power cables. Not if the fuel is in natural gas pipelines. I thought that the natural gas accessible to the UK was not all that much any more. The North sea is still full of it and we also import the stuff from Russia. The North Sea *was* full of it. It's another finite resource, much of which is being squandered to heat greenhouses, so that they can grow things that grow in the open in southern Europe. -- Martin |

Adding insulation, bonded to the cars sheet metal around the cabin, would improve matters. The drive motors and batteries produce heat, so this must be available for use. And also add to the cost and weight... Insulation should not add that much weight. Cost? Mass production will bring that down. I doubt that any heat would be available from motors if they are fitted into the wheel hubs. If they are. Most electric cars have one motor. There may be problems supplying enough electrical power for the demisters, seat heaters (oops, well I have a Saab), and other things (maybe needing a heater for the screen/headlamp wash and other currently unnecessary/rarely fitted devices). Cars are full of unnecessary crap which add cost and weight affecting fuel consumption, such as rev counters. Please have a feeling for quantitative matters. Your car is capable of producing more than 10^5 watts and you are mithering about an instrument which uses at most 5 watts to produce data which is very valuable for enabling you to use the engine effectively? Why does anyone need to know how much the engine is revving in a normal road car? Beats me. I know when it is revving, I hear and feel it. I find it a very useful device for helping me to decide on when to change gear. It is more quantitarive than just "having a feel for it" If it is revved too much the management system cuts it out. An electric window on the drivers side is unnecessary too, as are electric sunroofs, which are a British fascination. The French don't want to know them. At last we are in agreement about something Why isn't the a/c an absorption system using waste engine heat, instead of taking power off the crank, reducing mpg? Franz |

Unless you count biomass conversion in forests for indirect fuel generation. Agreed. Horses for courses. However tide power is not impossible either. Not an easy one tho. If only we could get fusion power working... Fusion power is going to turn out to be a great deal filthier than fission power. I don't think so. The fisson products would all be relatively short lived isoptopes, and teh main product is helieum. Non radioactve helieum Its only the vast amounts of radiation intereacting with the shielding that would cause some radioactive compounds to be generated. Fission power is the cleanest and least polluting energy source ever produced on earth. Yes, I tend to agree with you. The number of deaths per kilowatt hour which occur in the extraction and processing of fossil fuels is a lot higher than the corresponding number for the extraction of uranium I would not be surprised. The pollution of the atmosphere by fossil fuel stations is vastly worse than the pollution caused by nuclear power stations. That is certainly true. If all power stations were nuclear around the world the waste would pile up and be a huge problem in the future. Silly idea and should be forgotten. It is obvious that you have never given a moments intelligent thought to this question. You are just following the flock. The waste from a nuclear power station is in fact a great deal easier to dispose of safely than the waste from a fossil fuel plant. The trouble lies entirely in the fact that the shepherds who persistently lead the sheep astray on this matter have not even the faintest understanding of the issues involved in comparing methods of disposing of waste from power stations.

It is obvious that you have never given a moments intelligent thought to this question. You are just following the flock. My God, he is the only with insight now. The waste from a nuclear power station is in fact a great deal easier to dispose of safely than the waste from a fossil fuel plant. But is isn't!! It is dumped at the bottom of the ocean in casks that might last 100 years, then they will slowly leak their toxic contents into the ocean and into the food chain. This is a very sill idea. As people in the 20th century cursed the Victorian legacy of piled up dangerous slag heaps and other filth, future generations will think the same of us. The waste can be dumped down deep disused mines and then the seams concreted up. In 1000 years time some one will probably tunnel into it. Of course they will make a record, which will be lost. There are 4, 5 or 6 (no one quite knows) underground store of TNT under Belgium fields. No one quite knows where they are. These were the largest non-nuclear bombs ever made. The British would tunnel under the German trenches, fill with TNT and detonate, killing 10,000 men in one explosion from one bomb. The disused bombs were not used because the British trenches had moved forwards over them. One of these bombs went off by accident in 1955. Luckily no one was killed. It is a matter of time before the others explode. Records of where the bombs are? Some, but not all. If every powerstatio in the world was nuclear, where would all the waste go? Privately owned stations would cheaply dump the waste (illegal dumping of chemicals in all countries is common), insead of down expensive deep mines and sealing up with concrete. It is the human error aspect that is the flaw. When it goes wrong the effects last for 100s of years after. Also, cases of leukaemia are far greater around nuclear facilities. Just co-incidence the nuclear people say. ********!!! The trouble lies entirely in the fact that the shepherds who persistently lead the sheep astray on this matter have not even the faintest understanding of the issues involved in comparing methods of disposing of waste from power stations. They have a lot of common sense, that is clear. Dependency on fossil fuel power can be vastly reduced by use of insulation, passive solar, superior town planning eliminating cars, CHP, more efficient engines, etc, etc. --- -- Checked by AVG anti-virus system (http://www.grisoft.com).

No. In the reactions which are presently considered, there will be a lot of tritium around. Tritium is a gas and it has a long half life. It scares the pants off me. Tritium isn't all that bad. Its half life of about 12 years is short compared to millenia for fission waste. Tritium is a beta emitter with 18keV electron decay and there is quite a market in tritiated plastics for permanent glow in the dark (and still some requirement for H-bomb initiators). Emergency lighting in some applications is based on it. Fission power is the cleanest and least polluting energy source ever produced on earth. Yes, I tend to agree with you. You have to get the whole life cycle right though. And they still haven't an adequate solution for long term storage of high level waste. Regards, -- Martin Brown |
