Powering Restaurants WIth Deep Fried Fuel

Mike writes "Here's a brilliant idea for biofuels: rather than filtering used fry oil for use in vehicles, why not simplify matters and use it to heat and power the restaurant itself? The VegaWatt turns used vegetable oil into clean heat and energy for restaurants, eliminating the dirty and costly mess of oil disposal while producing 10-25% of the electricity needed to run a small restaurant. It also produces fuel free of chemicals or fossil fuels, unlike standard biodiesel."

      According to the article, the restaurant locations fry in vegetable oil, but the fries were partially fried in animal fat before they are frozen and shipped out to the restaurants.

      The fast-food chain had maintained for more than a decade that only vegetable oil was used in the hope of appealing to vegetarians and religious groups who do not eat beef products. Yesterday's apology triggered a violent protest by Hindus in India.

      The American company, which has served more than 200 billion portions of french fries around the world, confessed to a method of using beef fat to partly fry chips before they are sent to restaurants. They are then frozen and refried on the premises using vegetable oil.

      The price would certainly go up since, as waste, the oil is worthless(or even costs money to dispose of); but there is no reason to expect it to rise in price above other similar energy sources. If the cost of electricity is X, why would I ever pay more than X for vegetable oil? If nobody will pay more than X for vegetable oil, then it won't be cost effective to sell vegetable oil and buy electricity with the profits.

      The only exception to that would occur because of fixed costs and economies of scale. If, say, an oil generator costs $10,000,000, or if large generators have far better efficiency than small ones, then it would make sense for everyone in a given area to sell oil to a large producer, and buy electricity. Given that shipping costs money, the savings of centralization would have to be large enough to overcome the costs.

      1) No transmission loss from the power plant to the customer.

      You're missing the big picture: if the restaurant sells the oil for use in diesel vehicles, that displaces the dino-diesel the vehicles would otherwise use. If you assumed that the electricity the restaurant would use otherwise was created more efficiently than mining, refining, and burning the diesel in the vehicle, then selling the waste veggie oil wins.

      Restaurants can easily be powered with electricity generated from clean and renewable resources. Vehicles still need fuel, because [synthetic] gasoline and [bio]diesel work much better than batteries (or hydrogen, or any other alternative so far).
