The Green Speed Bump, an energy thief

New Energy Technologies speed bump.
 
New Energy Technologies (NET) in Maryland have created a speed-bump devise that can harvest kinetic energy from vehicles and convert that energy into electricity.  NET has been testing this technology for over a year and has “test bumps” in places like Roanoke, Virginia at a Civic Center and Hillside, New Jersey at a Burger King.  New Energy would eventually like to see its MotionPower Express devices at all areas where traffic, going faster than 15 mph, should be slowing down or come to a stop.  (ie: Toll plaza, stop lights, etc)
 
The MotionPower Express was used at a gun show at the Civic Center. Over 580 cars passing over the speed bump in 6 hours. The energy harvested could power an average U.S. home for a day.  Another test at a New Jersey Burger King gave them the estimate that their device would pay for itself in 2 to 3 years. Meaning it would make $2,000 USD during that time period.
 
Reports show that numerous companies have been interested in being able to harness energy in hope of offsetting electricity costs or selling back energy to the grid to state metering laws.  All these field tests are just helping us make another step toward a greener earth. Or so they say.
 
This tech is like public regenerative breaking, where that energy goes to the owner of the bump.  Yes, energy is being harvested from the speed bumps. As we all know, we do not get energy for free, it has to come from somewhere. The energy gathered is stolen directly from the vehicle passing over. They claim that the energy will be pulled from areas where cars come to a stop. It will take energy generated by the vehicle to overcome the bump. The question is, factoring in loss in the conversion, would it be better for the planet if the bump was not there at all?

    With money to be made without doing any work, it is going to happen.

    The energy is being expended anyway.  In this case, you are actually making each car that passes over the bump more efficient and reducing carbon by translating the kenetic energy developed into a source of energy for another use.  We also have to keep in mind that the property owners pay taxes to build roads that the motorists use, so if I rolled one of these bumps out in front of my house, each one of the 500 commuters coming into and out of my neighborhood would be "paying" me back for my investment in our local roads.  Seems to be a fair trade off.

    You comments are exactly my concern. It like tapping off of someone else's house.

    However, a business can have you do anything they want you to on their property. So, driving over a bump at a Burger King will just be part of the deal.

    I can see how these devises could generate power, but I wonder if the cost in fuel for the vehicle to drive over them would be more expensive than the power they generate.  It could well result in costing 100 dollars to generate 10 cents of power.

    Before they start putting these things all over, I hope the spend some time to calculate the true cost involved.  Plus, if the speed bump damages a vehicle, who is liable?

    It gets interesting when you start looking at all of the implications.
