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.
The machine that orchestrates this plasma-on-plasma violence is something of a monster, 23 meters long and 11 meters wide, studded with dials and gauges and overgrown with steel piping and thick loose hanks of black spaghetti cable. Officially known as C-2U, it’s almost farcically complicated–it looks less like a fusion reactor than it does like a Hollywood fantasy of a fusion reactor. It sits inside a gigantic warehouse section of Tri Alpha’s Orange County office building surrounded by racks of computers that control it and more racks of computers that process the vast amounts of information that pour out of it–it has over 10,000 engineer control points that monitor the health of the machine, plus over 1,000 physics diagnostic channels pumping out experimental data. For every five millionths of a second it operates it generates about a gigabyte of data.
In August, Tri Alpha announced that its machine had generated some very interesting data. So far the company’s primary focus has been on the long-enough problem, rather than the hot-enough part; stabilizing the plasma is generally considered the tougher piece in this two-piece puzzle. Now Binderbauer believes that they’ve done it: in June the reactor proved able to hold its plasma stable for 5 milliseconds.
In Texas, wind farms are generating so much energy that some utilities are giving power away (on left is a TXU sign)
Briana Lamb, an elementary school teacher, waits until her watch strikes 9 p.m. to run her washing machine and dishwasher. It costs her nothing until 6 a.m. Kayleen Willard, a cosmetologist, unplugs appliances when she goes to work in the morning. By 9 p.m., she has them plugged back in.
And Sherri Burks, business manager of a local law firm, keeps a yellow sticker on her townhouse’s thermostat, a note to guests that says: “After 9 p.m. I don’t care what you do. You can party after 9.”
Tampa Electric Co. is currently installing 7,000 solar panels atop a parking garage at Tampa International Airport, which will create enough energy to power 250 homes on an average day, or operate the 1.4-mile automated “people mover” train coming with the airport’s $1 billion master plan expansion.
Shortly after that project began, TECO announced plans for a much larger solar array on land near its Big Bend Power Station in Apollo Beach. That project will produce 25 megawatts of electricity, compared to the 2 megawatts the airport project will produce, making it the largest solar array in Hillsborough County. That is enough to electricity to power 3,500 homes.
University of Michigan engineers think they may have a next-generation solution to keeping photovoltaics out of the shade. Their idea comes thanks to the ancient Japanese paper-cutting craft of kirigami.
By building photovoltaics onto a flexible surface with strategically placed cuts, their prototype solar cells can transition from flat to three-dimensional surfaces with just a bit of pulling and pushing. They were able to control the array’s tilt to within one degree.
