Roman Baths algae could fuel cars

Researchers at the University of Bath are working on a new project to produce renewable biofuels from algae growing in the hot waters of the Roman Baths.

The oil contained in the algae cell is extracted to produce biodiesel. The oil content varies for different types of algae.

Researchers hope their project could pave the way for using theRoman Baths' unique algae to produce biofuels on a large scale for future transportation.

PhD student Holly Smith-Baedorf, who is working on the project, said: "Algae are usually happiest growing at temperatures around 25C (77F) and that can limit the places in which it can be cultivated on a large scale.

"Areas where these ideal conditions are available also usually make good arable areas and are therefore needed for food production.

"In an ideal world we would like to grow algae in desert areas where there are huge expanses of land that don't have other uses, but the temperatures in these zones are too high for algae to flourish."
