Watch How The World's Largest Solar Farms Get Built

Large-scale solar plants are monstrous construction projects, that cover hundreds or thousands of acres of land in photovoltaic goodness. This amazing video shows how they go from concept to reality.


Your Smartphone Could One Day Be Powered By Jet Fuel

Battery life on modern gadgets sucks — so why not power your mobile devices with something a little more potent like, err, jet fuel? That’s the idea of researchers from the University of Utah, who think that fuel cells could efficiently be made to run using the same fuel as fighter jets.


This Was An Electric Razor (And Face Massager!) In 1926

As electricity invaded American homes in the 1920s, everything imaginable was becoming electrified. From electric clocks and coffee percolators to electric dishwashers and stand mixers, every gadget was going electric. Even the sacred ritual of shaving one’s face was getting the electric treatment, as you can see in this early version of the Vibro-Shave electric razor.


Report: Solar Is Way Worse Than Other Renewables

Solar is an established — and constantly improving — form of renewable power. But according to a new report by the European Union its economic impact is incredibly costly, and far worse than wind and even hydroelectric power.


Rooftop Solar Panels Are Almost All Facing The Wrong Direction

If you’re thinking that solar panels face south to capture the most sunlight and thus the most energy, then you’d be absolutely correct. Yet, solar experts are saying that rooftop panels should be installed facing west. This surprising turn can be explained by quirks in the US’ electrical grid.


Monster Machines: The World's Biggest And Best Gas Turbine Can Power 400,000 Homes

If you thought the GE90 aircraft engine was a masterpiece of modern engineering, just get a load of this beauty. General Electric’s 9HA is the most advanced and efficient gas turbine available today and though it may not be able to lift a 787 off the ground, this potent electricity producer can easily power a mid-size metropolis.


US President Was Afraid Of The First White House Light Switches In 1891

The first president to install electric lighting at the White House was Benjamin Harrison in 1891, but he never touched the light switches himself, for fear of being electrocuted. This was a reasonable fear, given how crude household electric wiring could be at the time.


This Portrait Made With Electric Sparks Is The Ultimate Homage To Tesla

Video: Phil Hansen is a multimedia artist “who specialises in representative portraiture using media that connect to the subject matter.” This portrait of Nikola Tesla using electricity is the perfect example of that.


This Flapping Device Makes Electricity From Wind Rushing Past Your Car

As far as car accessories go, we have to admit this one looks pretty silly. But the Samsung scientists who made it could also be onto something. The flapping tongues inside are actually coated with gold, and when they rub up against a smooth plate, electricity is created through something called the triboelectric effect. It could be a whole new way to harness wind energy.


This Temporary Tattoo Is Actually A Battery That's Powered By Your Sweat

What if the sweat produced by your body could power your gadgets? And what if the connection between the two could be made by a temporary tattoo, the more you sweat, the more power the tattoo generates? That’s exactly what researchers at UC San Diego have developed — and one day, it could power your wearables.
