Making useful products from greenhouse gases

A new plant will use CO2 to both replace oil and be transformed into useful chemicals.

Speedy production of silicon for solar cells

A growing solar cell industry needs cheaper silicon in increasing amounts. A centrifuge developed in Norway could supply it.

Norway funds four green longshots

Giant batteries for storing renewable energy and solar cells that can use more of the light spectrum are among the winning projects that have been awarded additional funding from the Research Council of Norway.

Machines are better than people at sorting household trash

Novel technology makes it unnecessary to sort trash at home for recycling. But Norwegian authorities want us to keep doing it anyway.

Lasers catching the wind in rough seas

Wind gauges that use laser beams will soon be tested offshore where gigantic wind farms will operate.

The gentle drone

Not all un-manned aircraft are prowling military predators. Drones can also be deployed to chart ice fields and pollution, or locate people who’ve fallen overboard from ships.

Detecting oil spills with satellite

How to discern between a slick of oil pollution and harmless layer of microorganisms from an algal bloom? Bombard it with a radar from a satellite!

How to see through rock

It’s costly to drill deep into the ground for thermal energy. So you may want to know what’s going on down there. Mathematicians can help.

Hot rock gets a cold shoulder

Thermal energy is there for the taking in the rock below us if you have the equipment to drill deep enough. Oil producer Norway has the hardware and the know-how, but is there any spark of interest?

All-in-one algae

The alga starts by making hydrogen for fuel cells and consuming CO2. Then it can be converted into useful products like health food, fish fodder, medicines, construction materials and biofuels.
