Washington: A scientist, who is working to find an alternative for oil, has placed his bets on algae to become the fuel of the future.
Professor Juergen Polle, Professor of biology at Brooklyn College, told CBS News that planes cannot be flown with ethanol.
He asserted that to power a plane, oil is needed, and algae are capable of making oil as a drop-in replacement for fossil fuel.
Proponents find algae appealing, as it has the ability to grow in salt water.
What makes algae ideal is that it is also capable of growing in non-arable land and while it burns carbon dioxide like fossil fuels, it requires CO2 to photosynthesize, which makes it carbon neutral.
