Algal biofuel is an alternative to fossil fuel, which is generated by specific algae species from carbon dioxide.
A discovery in molecular chemistry may help remove a barrier to the widespread use of diesel and other fuel-efficient "lean burn" vehicle engines.
The far-ranging potential applications of this technology include DOE’s hydrogen fuel cell-powered “Freedom CAR,” and personal power-jackets that could use heat from the human body to recharge cell-phones and other electronic devices.
