People will get paid to drive and get paid for parking !

The people behind it are all Ph.Ds in material science, physics etc. from some of the best universities in the world and are senior research scientists at the Technion and specialize in various aspects of Piezoelectric technology.

The pilot itself was approved by Israel’s chief scientist as well as other scientific factors who examined the data and thought it had merit.

It may yet prove to have no merit — but these offhanded know-it-all comments are beyond belief. Lets wait and see what the EROEI (energy return on energy invested) is in regards to the financial ROI and then we shall see.

There should be a 2 kilometer slab for demonstration and pricing before anything is spread and dispensed and sold both mentally and physically.

You are mistaken when you claim that the energy comes from gravity. Any energy transferred to such a system comes from the car’s movement, and that movement is created by the car’s fuel. The car must become less efficient as energy transfers to the road.

Don’t mean to be pedantic but kWh actually stands for kilo watt hours which is a measurement of power over time. Power on it’s own is measure in Watts, thousands of them in kilo-Watts. Energy is measured in Joules or Calories, depending on your country’s standard.

I think such devices may have some value on off ramps and before stop signs. In such locations, making the roads softer may actually be of some benefit, as it would slow the car. But then, instead of 250 km or useful roadway, we would be down to probably 1 km of useful roadway in Israel.

I suppose the question is what is more feasible? Stiffening up the roads or harvesting the energy generated by the flex?

However this technology can also be used for applications where flex and vibration can’t be avoided so is worth researching.

To save such amounts of energy, they could invest the same money to make road surfaces easier to roll over for a car. A more high-tech tire also helps. It all costs, though.

Yet another idea: place turntable boards along highways, which re-direct the wind to create tailwind, each direction. See how much that saves. Yet, you will STILL save more by just placing as many windmills along the highway as will fit. While you’re at it, build a roof over the highway, stuffed with solar panels. Those may actually manage to collect enough to power some or all of the passing electric cars on sunny days, so they don’t need their own solar setup. Wireless transmission of electricity also exists now. And hey, no sun on the cars, so less aircon power used.

This piezoelectric is either a disturbed mind’s work, or a evil one’s, trying to divert attention and funding away from projects that DO CUT EMISSIONS.
Google : “GEET” and “HHO on demand”.

Improved roads/traffic is not as sexy though and hard to get VC’s interested and the big bucks wouldn’t go to the inventors pocket.
