Alternative fuel health worries

Scientists have today raised concerns about the health risks associated with the increased use of vegetable oil in diesel engines.
With recent rises in oil prices, motorists have been switching from traditional diesel to chip fat. Diesel engines will operate quite normally on various vegetable-derived products.
However, experts say that this practice may introduce health risks. Speaking from the AdeLabs Foodstuffs Propulsion Laboratory, Prof Kline Ikeleinsaen said:
"We are worried about passive obesity. Insufficient research has been carried out, but we have to ask: will people who breath through their mouths suddenly notice enormous weight gain?"
The vegetable oil industry was quick to dampen speculation about health risks. Mr Grave E Train 28 stone proprietor of Man Mountain Chip Shop supplies said:
"There is absolutely no evidence that running your car on vegetable oil will make pedestrians clinically obese. No-one has actually tested diesel. Possibly the rise in its use can be linked to increases in obesity."
Campaigners are also worried the effect on the environment. "If you can cook chips with this stuff," said Graeme Pace from the Campaign for Increased Greenity, "surely it must have an effect on global warming."
Meanwhile, investigations into alternative fuels may be at risk. "We are having to take a precautionary approach," said Prof Ikeleinsaen. "Research into cream bun based automotive fuel has had to be put on hold while we go into the whole thing."
