In conventional internal combustion engines, multiple pistons are connected via rods to a crankshaft that, via the transmission, drives the wheels. Free-piston engines do away with the crankshaft: the pistons aren't connected to anything. Instead, two opposing pistons just shuttle back and forth inside a chamber. To generate electricity, the pistons could be equipped with rows of magnets that shuttle past metal coils to create an electrical current.

Cool

Now we know where he sound effects of the Jetson's 'car' come from.

Basically just another generator, the product of which has to be utilised by electric motors to drive the vehicle.

The main advantage of course would be to eliminate the need to carry expensive or heavy fuel cells/batteries

That's a two stroke engine and would require an oil/fuel mix and more air polluting emissions.
