US scientists tip watermelon to be a fuel of the future
28 August 2009

Watermelons have been tipped as the car fuel of the future by researchers in the US.

More than 360,000 tonnes of watermelon are left to rot every year as they are unwanted to their unusual size or shape.

Farmers have been known to left between 20 to 40 per cent of their crops in the ground because of the same reasons.

But scientists at the United States Department of Agriculture in Oklahoma have found a way to create ethanol from the unwanted watermelons.

Scientists predict that there is enough juice in the wasted watermelons to produce around 2.5 million litres of ethanol each year.

Although this is small fry compared to the predicted total annual ethanol production of nine billion litres, the watermelons can cut the amount of water and nitrogen needed to create the fuel.

it's allowed - that one was a total sitter.

reminds me of how Richard Branson got slammed for promoting gimmicks by the eco warriors for using a similar idea to biofuel his VA planes using nuts and fruit normally left to rot at harvest time.

It's amazing what gets published when there is a shortage of news.

    It's got funky looks and a charming interior, but it's another small SUV, and another dynamic miss. Numb steering is just one thing keeping it from class best
  • Skoda-Karoq 2.0 TDI 4x4
    First Drive
    16 October 2017
    Diesel version of Skoda’s junior SUV is unobtrusive and undemanding, but we’d still go for the silkier petrol version of the Karoq
  • Audi Q7 e-tron

    16 October 2017
    Expensive and flawed but this understated diesel-electric Audi Q7 has a lot to offer
  • Citroën C3

    Is the third gen Citroën C3 ‘fresh and different’ enough to take on its supermini rivals? We spend six months with one to find out
  • BMW X3
    First Drive
    15 October 2017
    A satisfying rework of the X3 that usefully improves its handling, cabin finish, space and connectivity to make this BMW a class front-runner again
