Utility Exercise Credit

Mark
Sodderhamn, SE

Here’s a crazy idea I just had. You register at an official gym where they have exercise machines that generate power to the electrical grid, like a treadmill or lifting machine, etc. Feedback from the machine tells you how many calories — and how many watt-hours — you produce.

Now when you login, your electrical utility can monitor your contribution and discount your home billing by an automated credit. The more you work out, the more you save.

The credit could be slightly lower than the normal rate to offset administration and maintenance costs of such a system, resulting in a break-even scenario for the utility.

Where I live, both health care and electrical power are supplied essentially by the government through taxes. A lot of money is spent on both promoting fitness and energy conservation. A program like this could accomplish both at the same time and have a real impact.

There — that’s my idea.

Shoe Power

All of us walk at least 5 km a day from the time we wake up until we go back to bed. We can collect walking energy and convert it to electricity. Using a shoe that generates and stores electricity you will have enough power to charge your phone or night lamps from a day’s travel.

Parking Lot Power Grid

Philippines

Imagine all those thousands of cars parked for hours in a shopping mall with unused electricity stored in their batteries.

Each car could donate up to 50% of its battery level in exchange for free parking and help recover the parking lot’s usage of electricity. Or for huge parking facilities, cars could be attached to a power grid to power community needs and to offset carbon emissions while vehicles are not in use.

It only takes a few minutes to recharge the battery of a car while driving, then it’s ready again to donate the next time it parks.

Hybrid Exhaust Generator

George Lewis
USA

The idea is for use in hybrid cars. Capture exhaust manifold, catalytic converter, and exhaust pipe/muffler waste heat to create steam to drive a pump or turbine to create more electricity to charge the batteries of the hybrid vehicle.

This system in combination with a hho (oxyhydrogen) generator supplying hho to the intake of the engine could greatly reduce fuel used by hybrid vehicles and charge the batteries even when the vehicle is turned off.

Waste Water Power Plant

Giovanni
Montreal, PQ, Canada

Capture the energy of waste-water from tall and high-rise buildings as it flows down pipes to a reservoir installed just above and connected to a micro hydroelectric turbine before releasing the water in the sewer below.

These turbines are already used in creeks and small rivers… just substitute the creek with a sewer pipe. This is not a complicated idea. The various technological components already exists and are already in use. And there are no environmental impacts.

All that would be required would be to re-configure and assemble them for use in buildings. Some building modifications to accommodate the reservoir and the micro turbine would be required. Every edifice in the world releases a continuous stream of used water. A lot of energy is expended to bring that water up to each tap in each unit in each edifice… why waste the opportunity to recoup the energy from used water flowing down? Each building can easily connect this power source to the grid. Roof top rain water drains could also be connected to the system.

If every tall building in NYC was equipped with a micro turbine the amount of power generated would be significant. Additional small turbines can be installed in the cities sewer system to recycle the energy from the same water that gave power to the building it came from. Enough energy should be created to provide the energy used to pump waste water in to the treatment plants.
