Astronauts Can Power Their Bodies and Their Spacecrafts With Pee

Astronauts have been able to drink their own (treated and filtered) urine for years, but thanks to a new technique, scientists have managed to squeeze one more benefit out of an inevitable byproduct.

An RC Plane That Flies on Seawater Fuel

It's been almost a year and a half since we first reported on the U.S. Navy's plans to produce cheap liquid fuel from seawater.

Smog is Forcing France to Rethink its Love of Diesel

Last week, the smog in Paris got so bad, city officials made public transit free and banned half the city's cars from the road.

An RC Car That Runs On Water Is A Positively Charged Step

People have been talking about running cars on water for years, but it's a slow march from science fiction to reality. Even on a small scale, development is difficult. But the i-H2GO is the second revision of an all-water remote controlled car that seems to actually work. » 7/28/13 9:36am 7/28/13 9:36am

What Biofuel Is (And Where It Comes From)

Cars didn't always run on gasoline. Henry Ford envisioned his Model T's puttering along with tanks fully of ethanol. Early diesel engines ran on peanut oil. Of course, the discovery of massive petroleum reserves at the turn of the 20th century quickly put the brakes on that notion—why bother creating biofuel when… » 6/12/13 4:00pm 6/12/13 4:00pm
