Turning traffic into electricity

Taking wasted energy from auto traffic and turning it into
electricity sounds hard to believe, but these Israeli
researchers may be onto something
(h/t LukeHandCool):

Scientists in Israel say they have invented a way of
turning traffic into electricity.

The bright sparks at the country's Technion Institute of
Technology in Haifa have developed a road that generates
power when vehicles pass
over it.

And they hope the technology will reduce our dependence on
fossil fuels.

In a university car park, Haim Abramovich and his team run
a heavy truck repeatedly over a special stretch of
tarmac..

It could be used to power traffic lights or street lamps
already, but with sufficient progress the technology may
one day generate enough
electricity to send power to the national grid.

A company called Innowattech is working with the team to
develop the technology.

It estimates a kilometre of 'electric road' could generate
enough power for 40 houses.

Of course, all these Israeli inventions are nothing compared
to the advances in technology, medical care, and science
which come out of the countries that hate Israel.

Hmmm....

Let's see, we fight to improve gas mileage to reduce our
dependence on oil.....then they want to turn our cars into
parts of a generator which means the car motor has to work
harder to maintain velocity, meaning fuel mileage goes down,
meaning more need for oil.......


Unless you get an electric car which increases the demand for
more generators.


Terry Kennedy's idea is to use the WEIGHT of trucks (vs the
momentum of little cars moving) at all ports, truck stops,
etc., using hydraulics to run generators. Much better idea,
really.

So let's see. You drive your truck onto a surface that then
sinks beneath the weight of the truck, which then has to climb
uphill out of the depression using fuel to do so.....

Still a stupid idea, as all you're doing is using the motor of
the trucks to power your generators increasing their fuel
demand.


Well, if they were headed that way to begin with. Then you also
have that pesky little thing called inertia to deal with in your
scenario.

Terry's plan is just a VERY stout, slightly angled ramp that's
the equivalent to a speed bump in height...without the bump!
Once one (0ut of 4 to 6?) axles hits the ramp, it churns the
pumps as
stomps it down, as they leave the ports.
The "ramp" compresses to a normal "flat" road surface, and
springs back up waiting for the next axle.
An almost unmeasurable amount of fuel loss, times a THOUSAND
trucks per
day from a just ONE single port exit alone!

That's SAVINGS, and pretty smart, as far as I can tell.

Yet the fuel lose is measurable and is probably no less than what
a fuel powered generator would turn out directly, UNLESS as Dudu
points out you put them in where you would normally be seeking to
slow down anyway.



With the mileage that those trucks get, I would bet that the loss
would be a rounding error.

Perhaps, but when you hit them over and over and over.....well it
starts to add up, and in the end, we the consumer will end up paying
for this "free energy" and increase dependence on foreign oil.

No, energy is free and much of our electricity currently comes from
burning coal. How clean is that?

Fairly clean, and since coal is a domestic product which doesn't
increase our dependence on foreign oil........

Which is better.....to increase the fuel usage of trucks, or to burn domestic coal where we can produce cleaner emissions than those put
out by that truck?


BTW, a comma escaped out of my keyboard where it should not have. The beginning of that first sentence should read, "No energy is free.....".

I would venture the increase in fuel usage of those trucks to produce small amounts of electricity would be rather minimal compared to mining coal. In either case it would hinge on the comparitive efficiency between the two solutions.

And Coal is NOT "fairly" clean.
Momentum and force (gravity) is, and free!


Momentum may or may not be free, it was gained somehow was it not ?

Of course. Truck's gotta move anyway.
Foods rot if they don't move.



A truck on flat ground has to expend energy to change it's velocity and acquire forward momentum.

A truck at the top of a hil lhas great potential energy but how did it get there in the first place ?
It had to expend energy to move upwards at some point.

I know and understand that.




Brake pads are costly, so make sure the trucks leaving ports hit those hydraulic ramps that GIVE this "FREE ENERGY!" :/


Jake-brake


And truck stops and weigh stations?
Have them placed there as well, as when those trucks hit those hiway off ramps to fuel up...BINGO!

The harder-n-faster they hit them, the more SPINNING the fluids do to spin those generators!
