People are continually interested in creative ways to get rid of waste. The world has too much of it, so how could technology solve that problem by addressing another need? Hydrogen fuel cell vehicles are an emerging possibility.

The processes used by many forward-thinking companies center on converting waste into hydrogen energy. Here’s a look at what the future may hold.

Waste-to-Energy Projects Are Happening

China has revealed a prototype for a new high-speed Maglev train that is capable of reaching speeds of 620 kilometers (385 miles) per hour.

The train runs on high-temperature superconducting (HTS) power that makes it look as if the train is floating along the magnetized tracks.

The sleek 21-meter-long (69 feet) prototype was unveiled to media in the city of Chengdu, Sichuan Province, on January 13. In addition, university researchers constructed 165 meters (541 feet) of track to demonstrate how the train would look and feel in transit, according to state-run Xinhua News.

A green sea slug appears to be part animal, part plant. It’s the first critter discovered to produce the plant pigment chlorophyll.

The sneaky slugs seem to have stolen the genes that enable this skill from algae that they’ve eaten. With their contraband genes, the slugs can carry out photosynthesis — the process plants use to convert sunlight into energy.

This is the third installment in a three-part series. Read parts one and two.

In the third and final part of our series, Fusion Industry Association director Andrew Holland tells Asia Times’ correspondent Jonathan Tennenbaum how the private sector is leap-frogging government programs in the race to develop commercial fusion power plants.

Andrew Holland: So now the private sector is coming in. You mentioned high-temperature superconductors. That’s an important new thing. There’s a whole range of new developments that come from outside of the fusion space that are now being applied.

Student-led teams aren’t the only ones testing out novel electric propulsion techniques recently. Back in November, a company called Exotrail successfully tested a completely new kind of electric propulsion system in space – a small hall-effect thruster.

Hall effect thrusters themselves have been around for awhile. However, they have been limited in their practicality, primarily because of their size. Normally they are about the size of a refrigerator and require kilowatts of power, making them impractical for any small satellites.

That’s where Exotrail’s novel system shines. It is about the size of a 2 liter bottle of soda (or pop if you’re from that part of the world), and only requires around 50 watts of power. This makes the propulsion system ideal for satellites ranging from 10 to 250 kg.
