# Well cars normally run along roads
and speed ramps that don't generate electricity. This is harnessing a little kinetic energy that normally would have just vanished into oblivion.

The cars will run on the road anyway, if they generate elctricity or not.

I see no harm in it.

# ^Both of these; IF they only replace ordinary speed bumps
I can forsee these things being installed everywhere, in addition to current bumps, increasing everyone's fuel consumption/emissions etc 'in the interests of the environment'

# Would be nice if they could integrate it
in to the hydraulic ones proposed ages ago- they disappeared in to the ground if you're under the speed limit.

# there is something intrinsically cheeky about it
when you consider the road tax and other tolls they want to start charging road users.

we should just drink the petrol ourselves and ride bicycles instead

# I just paid £505 out
to keep my car on the road. I'm gonna use the damn thing.

Yes, even if I go next door.

# It is funny how
'for environmental reasons' there is a massive petrol tax;
and 'for environmental reasons' they do everything possible to slow traffic down, thereby consuming MORE petrol and doing absolutely nothing for the environment....

# Do the cars have to slow down to go over them?
As I read it, the car depresses the platform, not drives over it like it would a speed bump

# It will still take momentum from the vehicle;
which would be replaced by burning fuel

And the electricity generated = far less than the fuel burnt

# How much fuel
would a car have to burn to give it enough momentum to drive over a 3" high ramp?

# *calculating*.......
Assuming a car mass of 1000Kg
1000Kg * 9.81 N/Kg = 9810N
* 10cm = 981 Joules
Effeciency of a car engine = approx. 30%
- friction losses = approx 25%
981J * 4 = appx. 4KJ per car
* thousands and thousands of cars...
