The current versions of the tiles actually have a two percent loss on efficiency, so 98 percent of what you’d normally get from a traditional solar panel, according to Elon Musk. But the company is working with 3M on improved coatings that have the potential to possibly go above normal efficiency, since it could trap the light within, leading to it bouncing around and resulting in less energy loss overall before it’s fully diffused.
Of course, there’s the matter of price: Tesla’s roof cost less than the full cost of a roof and electricity will be competitive or better than the cost of a traditional roof combined with the cost of electricity from the grid, Musk said. Tesla declined to provide specific pricing at the moment, since it will depend on a number of factor including installation specifics on a per home basis.
SolarReserve’s Sandstone project would include up to 10 concentrated solar arrays, each equipped with a molten salt system capable of storing the sun’s energy to generate power after dark, CEO Kevin Smith said.
The company already has built one such array, the 110-megawatt Crescent Dunes Solar Energy Plant, on 1,600 acres of federal land outside of Tonopah, 225 miles northwest of Las Vegas. The $1 billion array began delivering power to NV Energy late last year.
Smith said project Sandstone would generate between 1,500 and 2,000 megawatts, enough to supply about a million homes. That’s on par with a nuclear power plant or the Hoover Dam and far bigger than any of the world’s existing solar facilities.
The idea behind a metal air battery is to use air—which is free, lightweight, and widely available—for the cathode part of the battery. Metal air batteries basically suck in the freely-available air and can ditch the heavy casing that would normally hold the anode material inside the battery. Using air basically makes these batteries fundamentally lighter and cheaper.
Fluidic Energy makes a specific type of metal air battery called a zinc-air battery. Zinc, which is abundant and low cost, is the key material that sits in the electrolyte of their battery and moves onto the anode during charging and discharging.
The little EV may look like just another five-door compact, but two figures make it an engineering masterstroke: 200 and 30,000.
That first number is its range: 200 miles on a fully charged battery. That’s a number exceeded only by Tesla, whose cheapest model starts north of $70,000. And that brings us to the second number. Chevy promises the Bolt will cost less than $30,000 after the $7,500 federal tax credit. Together, they make the Bolt the first EV that delivers excellent range at a great price. It is the electric car for the masses.
A new On The Go (OTG) wearable charging cable for smartphones, called Thino, is a portable charger, battery back-up, and data transfer all in one compact, durable and lightweight aluminium body! Thino has a dual side USB connector and is able to detect and switch between different USB charging methods such as charging downstream port (CDP), dedicated charging port (DCP) and standard downstream port (SDP). Thino is able to supply any Android and iOS device with the maximum current it can draw from the source. The built-in 480mAh Lithium Polymer battery can be used as a portable back-up battery to keep your device up and running for 2 hours.
Though city dwellers may not realize it, agriculture is a big source of carbon emissions. That’s because of livestock’s production of methane, how manure is handled, and soil management (something as simple as tilling the soil releases greenhouse gases). Dairy geniuses Mike and Sue McCloskey, partners in one of the country’s biggest dairy operations, have come up with an elegant approach to tackling several of these problems at once in the hopes of creating a zero-carbon footprint dairy farm. At the heart of the operation: a process that turns their dairies’ tons of cow manure into natural-gas fuel. Here’s how it works.
Renewables just finished another record-breaking year, with more money invested ($329 billion) and more capacity added (121 gigawatts) than ever before, according to new data released Thursday by Bloomberg New Energy Finance.
This wasn't supposed to happen. Oil, coal and natural gas bottomed out over the last 18 months, with bargain prices not seen in a decade. That's just one of a handful of reasons 2015 should have been a rough year for clean energy. But the opposite was true.
Using new superconductive materials, Whyte’s team (at MIT) has designed a fusion reactor they say should be able to profitably generate grid-scale power using smaller equipment at a much lower cost than current models under development.
1. Materials The team’s highly conductive magnetic coil, made from rare-earth barium copper oxide, requires less cooling than coils in other models. This helps reduce the reactor’s volume and weight by a factor of 10, Whyte says.
2. Results At the size of “a small building,” the reactor’s added conductivity would also double the strength of its magnetic field, upping fusion output by volume 16-fold, Whyte says.
StoreDot says its smartphone batteries can fully recharge in 60 seconds, compared with an hour and a half for the average device. Proprietary amino acids, used in place of some of a typical battery’s lithium components, allow for safer, quicker charging, StoreDot says.
Cheniere Energy, based in Houston, has spent more than a decade, and upwards of $20 billion, turning 1,000 acres of swamp into the first LNG export terminal in the continental U.S. When the terminal goes live later this year, it will change the dynamics of the energy market in North America. The U.S. will be on its way to becoming a net exporter of natural gas. About 700 million cubic feet of the stuff will begin arriving each day from all over the country—from Texas, Pennsylvania, Ohio, and as far away as North Dakota—to this spot at the end of America’s natural gas pipeline network.
At the terminal, the gas will circulate through roughly a mile of steel pipes and refrigeration systems organized into metal racks spread out across the plant. The racks aren’t unlike the one on the back of a household refrigerator, except they’re 500 feet wide and a quarter of a mile long. In the heart of each rack are two “cold boxes,” the biggest of which is a 1,400-ton, seven-story steel rectangle.
Over about five minutes, the gas will cool until it becomes a super-dense liquid, weighing 3.5 pounds per gallon, after which it will get pumped into those giant storage tanks. From there it will be loaded onto foreign tankers and sold to customers worldwide, from power utilities in Spain and Britain to state-owned gas corporations in India and Korea.
