Electric engines seem to be a promisein developing high-performance and noenvironmental pollution...
It is definitely possible to build a gas turbine small enough to fit in a car, the military have man portable gas turbine water pumps for fire fighting. I think the problem is more maintenance, and fuel efficiency, as I think small turbines are probably not very fuel efficient.
Hi George its really nice to see your back. That must have been one hell of a new years hang over you had, next time send me an invite
Talking about gas turbines and things ,did you know there was a motor cycle manufacturer i believe in America who actually built and sold a large number of motor cycles powered by an actual jet engine which was as usable as any other bike. The only reason it didn't catch on was due to the riders burning themselves on various parts of the bikes.
Battery powered vehicles are the only way forward.Serious advances in battery and capacitor technology really should have the 'Hydrogen Economy' exponents shutting up shop by now. The trouble is with who owns the chain of energy supply - the likes of BP, Shell, Exxon - want to keep hold of their monopoly and so Mr.Bush and Mr.Blair back them by wasting public money for research and development.
Hydrogen is such an inefficient and inconvenient way of moving about. It uses so much energy to creaate it, it's dangerous, and as I understand it causes catastrophic damage to the atmosphere - more so than C02.
The problem is not so much whether one fuel is better than another, the problem is trying to set up the infrastructure to support it. In that respect, it matters not whether you are talking about hydrogen or battery, you need the support infrastructure to allow you to top up during your journey (i.e. filling stations). The car is the easy bit.
Even better bio-diesel can be made from all the waste oil and fat available from food production and sale establishments every where. Just wait until you can fill the car and the occupants at a McDonalds or Burger King drive through?
Petrol/electric Hybrids like the Prius do not deliver anything like their claimed mileage in real life
use and battery cars are a joke. If you work out their MPG from the quantity of fuel needed to be used to generate the electricity needed to charge the battery and then look at the pitiful range they have they are simply short distance city cars at best.

The government will never agree to anything other separate distribution channels for motor fuel so that it can be taxed separately.QuotePetrol/electric Hybrids like the Prius do not deliver anything like their claimed mileage in real lifeThey are still very early technology (you made the point about how much the diesel has improved in the last quarter century, but the hybrids have only been here for less than a decade).I actually see diesel to be a logical partner to hybrids, since the lack of flexibility of a diesel engine scarcely matters when you use an electrical transmission system.Quote use and battery cars are a joke. If you work out their MPG from the quantity of fuel needed to be used to generate the electricity needed to charge the battery and then look at the pitiful range they have they are simply short distance city cars at best.The major advantage of battery cars is low weight - otherwise, little else.Range is something that is constantly improving, but at present they are a niche market (although if they can be produced cheaply enough, they could make a very useful second vehicle for local trips).
No reason why McD and BK couldn't have pumps as well many are in any case located on or close to filling stations. It is possible to register as a bio-diesel producer/user and submit your own returns to HMR&C to pay the duty post use. I know several people who have done it.
Peugeot Citroen and I think Smart are already developing diesel hybrids and you are wrong in stating that the technology is less than a decade old. Railway locomotives have been using TRUE hybrid technology, both diesel electric AND diesel hydraulic for decades.
Diesels do not suffer from "lack of flexibility" my daughter's Punto JTD will do from below 30 to over 100mph quite smoothly in 5th gear.
To suppliment the mcD and BK fuel supply I made a proposal on another site that liposuction clinics should donate their erm... byproducts (which are likely to be have been sourced from mcD and BK) so that the couch potatoes of the future can do their bit for humanity...
