This is a pretty nifty idea.

Wow, what a great idea. Hopefully the applicate can become more widespread.
 
That's so clever. I'm amazed this hasn't been thought of before now!
 
Yeah - that is a good idea... these damned inventors! ;)

So, enough to charge a battery for the nearby streetlamps perhaps?

What I want to know though, is how often it's been rated to go up and down - as in how much maintenance will it need and how much traffic load can it handle.

Still, hope it becomes a reality... as long as they don't power speed cameras...
 
ricers with your cars lowerd 4 inches, be warned :lol:

Not only them, that ramp looks rather high... Even drivers of half-decent sportscars will get into trouble.

That's why this invention is getting :thumbsdown: from me.
 
Well, I don't think they'll drive onto it like how the pic is, I think they'll come from the other way. If that's the case, it'll go down as you drive onto it, so...
 
^ That, and if they extend the length of the ramp the angle will be better.

Maybe, but why would they let the cars drive in the wrong direction on presentation pics?

Even if you're coming from the other site, there's still the possibility of scratching the underside of your front bumper before the wheels reach the ramp.
 
e=mc?

e=mc?

What a stupid idea.

You can't create energy from nothing so all that is happening is that you are replacing efficient mains generated electricity with inefficient locally generated electricity.

Individual drivers may not notice the tiny extra amount of fuel used but it's still being used.

Solar/wind powered signage is a far better idea in remote areas, and unlikely to cost as much as ?25k.

Depending on the weight of the vehicle passing overhead, between five and 50kW can be generated.

Is that a lot? How much does a family consume a year?

It's 67bhp.

It's over 200A @ 240V, or >450A @ 110V

You can boil 20 kettles with that.

It's a lot of energy to remove from a moving vehicle.
 
That's not bad at all. However I too have my doubts about the durability of such a thing. Moving parts and complex machinery, in all weather conditions, all temperatures, salt, snow, ice, half-molten asfalt, overloaded trucs, heavy machinery, cars driving too fast... This thing should be extremely durable. And it will need batteries too which will have to be replaced anyway...
