Watch An Awesome Lightning Bolt Get Captured In A Box

What we’re seeing is Lichtenberg Figures form from an electron beam getting zapped into an acrylic prism. The electric trail of the lightning strike is so badass. It’s like trapping a lightning bolt in a glass box forever, a force of nature on display.


How Tesla's Powerwall Stacks Up To Regular Energy, By The Numbers

I think about big, cheap batteries for a living, so I stayed up late and listened to the Tesla announcement. My first thoughts: These are fantastic prices for an uninterruptible power supply — but they’re still expensive as day-to-day electricity.


Tesla Powerwall: A Battery For Your Home

Tesla has just made a very exciting announcement. It’s now using its clean energy nous not only to make some of the world’s best electric cars, but also to power your home.

Tesla Energy wants the world to be cleaner, and it’s doing so by letting homes, businesses and power companies store their electricity better and reduce peak load on the grid. Here’s the best part — we’ll get the battery in Australia too, at an incredibly cheap price. It’s called Powerwall.


Pencil Lines Can Turn A Piece Of Paper Into A Simple Sensor

The graphite that slips from the point of your pencil onto a page may be of more use than simply writing and drawing. A team of researchers has shown that simple pencil lines can be used as an accurate sensor to measure the deformation of objects.


Repairing High Voltage Lines Is One Of Most Scary Jobs I've Ever Seen

This excerpt from Straight Up: Helicopters in Action — a documentary released on IMAX theatres a few years ago — shows the dangerous daily routine of the guys in charge of fixing the high voltage lines. One of the workers say that even if you’re afraid of heights or electricity you can still do this job — I seriously doubt it.


This Flexible Skin Patch Could Use Friction To Power Your Wearables

The idea of capturing some energy from you constant writhing and wriggling ins’t new — but this small, flexible device certainly is. The postage stamp-sized circuitry, once attached to the skin, could generate electricity to power the gadgets secreted about your person.


Incandescent Bulbs, 135 Years Ago And Today

On January 27, 1880, Thomas Edison was awarded a patent for an incandescent lamp. It was still two years before his first power grid would flicker to life in NYC, and Edison was living on the precipice of a new age. Oh, how things have changed.


The Forgotten Story Of NYC's First Power Grid

Lower Manhattan of the 1880s was a wonderland of futuristic technology and engineering: The city’s first cable car arced over the harbour. A spindly new steel bridge was forming to connect Williamsburg to the city. And on the Lower East Side, Edison was tearing up the streets to build the first permanent power station in the world.


California's Grid May Soon Store Energy In Giant Ice Packs 

California wants better batteries, which is why the electric company Southern California Edison is planning a set of, let’s say, unconventional energy storage solutions, including huge 450-gallon ice packs. Why? It all has to do with a little-known problem with California’s wind-reliant electric grid.


Your Set-Top Box Is An Energy-Sucking Monster (But It Doesn't Have To Be)

An innocent little cable box can suck up more electricity than your actual TV. The most galling part though? Up to two-thirds of its power-hogging actually happens in “idle” mode, when you’re not even using it. The good news is device makers have the technical ability to make cable boxes that don’t waste so much electricity. They just need to actually do it.
