wouldn't necessarily have to generate loads of current, a coil on bottom of car passing over permanent magnets, cost would be minimal.
scalextric type tracks would work, but, cost would be exhorbitant.

Interesting idea but I suspect the 'Laws of Physics' would intervene to make it unworkable (otherwise why hasn't somebody done it, maybe with trains)? Sounds like an idea for a perpetual motion machine to me  Confused

Perpetual motion unobtainable, you are driving along using battery power, would only extend range, couple that with a flywheel generator.

Just driving over permanent magnets the energy you'd gain from the charge would be less than the extra energy required to move through the magnetic field.
One could in theory have a kind of contactless charging system built into the road surface, but it would almost certainly be orders of magnitude more expensive than rigging up overhead electric cables like a trolleybus...

You could put the car on rails, too. And seeing as once you are on rails, you can't overtake, you may as well fix all the cars together...

Suddenly, the means to travel long distances using electricity turns out to already exist.

Spot on Rupert!

I know people who believe the future is in self driving Uber style transport, locally (I remain to be convinced). That could combine quite well your invention - lets call them "trains" - to cover longer distances.

However, back to the title of the thread - the interesting bit is how you would tow your boat? I remember some years back a friend at my old club got his bus pass and we were trying to work out how he could do the travellers circuit with his Contender using his pass. We decided that to get it to work buses would have to be fitted with tow bars. Perhaps the same idea could be reused?

Trains only any good if they are leaving from where you are and going where you want to go, sorry, but, personal transport never going away, so,keep thinking.

Ok, we don't buy personal transport, we subscribe to it, you do have an electric vehicle at home and you drive it to the station, when you get off the train you drive a different one to your destination and use it to return to the station when it's time to go home. At your home station you pick up a different EV to drive home (it's a bit like 'Boris Bikes'). Where this all fails though is that it will be so much cheaper to use the EV than the train you may as well just drive all the way. Then, 'cos the cost of the corporates making a profit out of your EV 'sub' it turns out it's much cheaper just to buy your own in the first place...... Ah, now we're back to personal transport..... bugger.......  Cry

I worked out the solution ages ago, would have even helped the oil companies. The answer should have been standardisation of the battery, which should be able to be changed, wheel in wheel out, filling stations keep a supply of charged batteries (charged by Solar Panels) and a small charge to swap your battery for one fully charged.
Filling stations get to continue to be of service, no long charge times and competition range around the battery suppliers and the range they offer. This of course would have required a Government at either national or Europe level not in hock to the oil lobby.

Some logistics issues, mostly 'cos of the weight of the batteries but that's probably the only workable solution unless Hydrogen Cell technology catches up.
