TNT-Coated Carbon Nanotubes Could Generate Future Electricity

Light the touchpaper and stand well back, because we’re about to… make sustainable electricity? That’s the idea according to a researcher from MIT, whose vision for future power generation involves a healthy dose of TNT.


IKEA Is Betting Big On These Six Small Tech Companies

IKEA is one of the largest corporations in the world, and even the smallest change in its supply chain could have a gigantic impact on its business. After all, this is a company that uses 1 per cent of the world’s wood supply. In fact, IKEA operates a whole venture fund devoted to emerging tech, from ice cream to batteries.


Scientists Pulled Hydrogen From Water Using An AAA Battery

Zero-emissions hydrogen fuel cells seem like a great idea. At least they do until you realise that isolating the hydrogen that powers them creates a crapload of greenhouse gases. Now, a Stanford grad student thinks he’s found the answer — and it involves a AAA battery.


Why This Company Wants To Build Data Centres Next To Gas Storage Sites

The problem with data centres is excess heat. The problem with liquified natural gas terminals is excess cold. In a perfect world, one problem would neatly cancel out the other — which is exactly the world imagined by Massachusetts-based TeraCool. Coupling data with liquified gas could make a lot of energy sense.


The Sounds Around You Could Soon Charge Your Phone's Battery

Sitting in a noisy bar, caring for screaming children, or watching the ball game — all awful locations to make a phone call, but soon these scenarios could actually help charge the battery of your cell.


Cheap Solid-State Batteries That Last Twice As Long As Li-Ion Are Coming

Most of our devices run (not for long enough) on lithium ion batteries. But there could be a new, old kid on the block — in the shape of a solid-state battery that can hold twice the charge as li-ion.


The First Supercomputer-Designed Wind Farm Is Heading To Mexico

Mexico is getting a brand new wind farm from a Spanish company called Iberdrola, and it’s no ordinary field of windmills. This one will be the very first to be designed by a supercomputer. Humans: who need ‘em?


How One Airport Will Frack For Gas Under Active Runways

Pittsburgh International Airport has seen better days. Saddled with debt from building now unused gates, the troubled airport is expanding into a completely different business: fracking. The airport will stay open as drillers tap the gas reserves underneath, thanks to a technique called horizontal drilling.


Stinky Landfills Might Soon Generate Clean Energy

Hydrogen can be devastating, but in the right hands, it can also be awesome. When burnt, for instance, it emits only water vapour instead of nasty carbon dioxide that’s responsible for much of the climate change we see today. Now, researchers have discovered a way to convert methane — the same gas that makes landfills stinky — into hydrogen by making it react with carbon dioxide itself.


This Smart Skyscraper's Shades Bend And Fold To Keep You Comfy

It’s the very worst part of working in a giant climate-controlled building: Depending on the time of day, half of the offices end up roasting while the others freeze to death. How about a smart skyscraper skin that adjusts window by window based on the angle of the sun, saving energy and allowing workers to control their own temperature destinies?
