New Green Energy System to Capture Waste Energy

A European supermarket chain, Sainsbury's is going to open its first "people-powered" store at its new store in Gloucester, using technology which captures energy from vehicles to power its checkouts.

Whenever a vehicle passes over the "kinetic road plates" positioned in the car park, energy is captured which would otherwise be wasted. Sainsbury's will channel the energy back into the store, saving power that would normally be taken from the National Grid.

The kinetic road plates are expected to produce 30kW of green energy an hour, which is more than enough to power the store's checkouts. The system, pioneered for Sainsbury's by Peter Hughes of Highway Energy Systems, does not affect the car or fuel efficiency, and drivers feel no disturbance as they drive over the plates.

  In the beginning, there were algae,
but there was no oil Then, from algae came oil.
Now, the algae are still there, but oil is fast depleting
In future, there will be no oil, but there will still be algae  
So, doesn't it make sense to explore if we can again get oil from algae?
This is what we try to do at Oilgae.com - explore the potential of getting oil from algae
