A company in Japan, called Genepax, has just created a prototype for a water-powered car. Watch the video to check it out. Undoubtedly, this is a PR stunt and there are no details on how this car manages to run on a glass of water, but this brings a lot of promise to everyone who dreams of an alternative to filling up your tank with gasoline.

However, consumers and investors need to be wary of companies that sell snake oil to cure your every ailment. It is no coincidence that these types of stories surface when the price of gas tops $4 a gallon in the United States. Rather than pin our hopes on a technology that does not yet exist, people may take some more practical steps to reduce their reliance on petroleum-based products. A few steps are listed after the jump.

1. Take mass transportation to and from work.
2. Whenever possible, walk, bike, or carpool to a destination.
3. Have groceries delivered to your house.
4. If possible, telecommute to work.
5. Move closer to work.
6. Keep your car properly maintained so that it can get the best mileage possible. (Keep your tires inflated and make sure your car has all of the necessary fluids.)
7. Remove heavy and unnecessary items from your car.
8. When you drive your car, drive the speed limit. It helps conserve gas and its safer than speeding.
9. Buy and drive a smaller, fuel-efficient, used car.
10. Instead of taking a road trip, try a taking a stay-cation.
11. Plan your trips to take the fastest route possible to avoid gas-burning traffic.
