Speed Bumps That Also Generate Electricity
The Four Seasons hotel in Washington, just a dozen blocks from the White House, is approached not by a simple semicircular driveway, but by a covered porte cochère. On Monday, travelers arriving there by car will slow down for what looks like a speed bump, but is in fact a new way to generate electricity.
According to Meetesh Patel, president and chief executive of New Energy Technologies, a car passing over the company’s small ramp pushes down embedded actuators connected to a generator. New Energy Technologies isn’t being too specific about how its MotionPower device works or how much electricity is generated, but driving over the ramp turns on a green light — providing visual confirmation that the device is working.
