Add Moletech to the growing list of companies trying to cash in on going green -- they claim their new Fuel Saver cuts down on emissions and improves fuel economy in all fossil fueled engines.

The "universal product" comes in eight models to fit any size vehicle from cars to scooters to boats, with prices ranging from $119 to $299 USD. If you install one in your Prius and start contributing back to the grid, be sure to let us know.
