This Disgusting Pink Plume Could Help Us Clean Up Oil Spills

Even after Deepwater Horizon we're still not ready for the next big spill—but that doesn't mean we're not trying. This weird pink plume could help. » 10/22/14 5:20am 10/22/14 5:20am

Planes Will Start Running on Biofuels From Fallen Trees in Two Years

Now here's some welcome innovation in the airline industry. Southwest Airlines announced today that it will be using biofuel on several of its flights by 2016, purchasing the blended fuel from a Colorado company that salvages "140,000 dry tons of woody biomass feedstock" per year—fallen timber from local forests… » 9/24/14 4:10pm 9/24/14 4:10pm

Scientists Engineer E. Coli to Make Propane

E. coli is an exceedingly common bacteria that lives in many places including your very own gut. It's also a favorite organism for synthetic biologists looking to engineer useful microbes. By inserting just a few genes in E. coli, scientists have found they can coax the bacterium into making ready-to-use propane. » 9/02/14 5:10pm 9/02/14 5:10pm

This City-Sized Gas Plant Has The Next Big Idea To Save The Planet

Nine billion tons of things you buy get to your hands via trucks. Most structures are put up by cranes and bulldozers. All those vehicles run on diesel, and at the Pearl Plant in Qatar, Shell is cooking up an alternative fuel that could drop directly in those engines, making them immediately more efficient and more… » 7/08/14 2:17pm 7/08/14 2:17pm

The Navy's Huge, Hidden Problem: Barnacles on Ships

It's a problem as old as sailing itself. Ever since man set out sea, barnacles have been clinging like, well, barnacles to ships, growing into bumpy masses that slows down vessels and wastes fuel. Could the solution to this age-old dilemma be a new coat of special paint? It's not as simple as it sounds. » 5/07/14 3:40pm 5/07/14 3:40pm

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. Now, astronauts can use their urine to keep both their bodies and their spaceships running smooth. » 4/11/14 11:00am 4/11/14 11:00am

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. And as a proof of concept, the unmodified two-stoke engine in this P-51 Mustang remote control model plane was recently powered using the new liquid fuel instead of traditional gas. » 4/07/14 11:20am 4/07/14 11:20am

Scientists Have Created Bio-Rocket Fuel

For those of you concerned that rockets, jet fighters and the like aren't environmentally friendly, some good news: scientists have worked out how to use bacteria to create rocket fuel. » 3/27/14 11:20am 3/27/14 11:20am

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. The vehicle ban only lasted a day, with the reduced traffic and changing weather patterns alleviating the smog situation. But why did the smog get so bad in the first place? Blame France's… » 3/20/14 6:40pm 3/20/14 6:40pm

LaCie's Fuel Tank Is Filled With 1TB of Wireless Storage, Not Gasoline

Even if you've splurged on the most capacious smartphone or tablet you can find, at one point you're still going to run out of storage space. And in lieu of constantly swapping tiny memory cards, LaCie's new Fuel offers a full terabyte of storage that's available to your mobile devices via a direct wireless connection. » 1/05/14 7:00pm 1/05/14 7:00pm

What Causes Spontaneous Combustion?

Most of us experience combustion, a chemical process where a fuel combines with oxygen to produce heat and light, in the form of a fire where both the fuel and ignition source are well known. » 12/19/13 5:15am 12/19/13 5:15am

Artificial Photosynthesis: Making Cheap Hydrogen From Water and Light

Hydrogen is one of the most promising fuels of the future but right now it's expensive to produce in bulk. Enter the work of a team of Stanford researchers who believe they can make it as cheap as fossil fuels—using just some water and sunlight. » 11/19/13 9:40am 11/19/13 9:40am

This Dynamic Robot Duo Is Making Solar Power Cheap As Hell

Solar power is fantastic, sure. But while the tech behind solar panels is zooming forward, there are other problems holding it back. Problems like installation and cleaning. Fortunately robots are here to help. » 10/14/13 4:40pm 10/14/13 4:40pm

How Do Gas Pumps Know When to Stop?

If you've ever put gas in a car, you'll know that the pump magically knows when to stop spewing fuel into the tank. That's super useful, and safe too. But how does it know when to stop? » 10/01/13 6:19am 10/01/13 6:19am

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

This Eternal Flame Burns as a Result of Natural Fracking

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

Universally Accessible Energy Will Be Worth The Cost

There's Gross Alternative Fuel Just Hanging Out in the Sewers

Everybody knows about using oil as a fuel source, but London is putting a new spin on the concept. Soon the city will be mining its own sewers to bring up glorious globs of old cooking grease and melting them down into fuel. Delicious. » 4/10/13 1:18pm 4/10/13 1:18pm
