The giant honeycomb-like setup of 149 spotlights — officially known as "Synlight" — in Juelich, about 30 kilometers (19 miles) west of Cologne, uses xenon short-arc lamps normally found in cinemas to simulate natural sunlight that's often in short supply in Germany at this time of year.
By focusing the entire array on a single 20-by-20 centimeter (8x8 inch) spot, scientists from the German Aerospace Center, or DLR, will be able to produce the equivalent of 10,000 times the amount of solar radiation that would normally shine on the same surface.
Creating such furnace-like conditions — with temperatures of up to 3,000 degrees Celsius (5,432 Fahrenheit) — is key to testing novel ways of making hydrogen, according to Bernhard Hoffschmidt, the director of DLR's Institute for Solar Research.
Many consider hydrogen to be the fuel of the future because it produces no carbon emissions when burned, meaning it doesn't add to global warming.
Sounds dreamy, right? Some heroic researchers at the University of Michigan and Cornell have engineered a special material called "magnetoelectric multiferroic," which has hugely exciting potential for environmentalists and tech manufacturers alike. It will allow computers of the future to operate using just a few quick pulses of electricity rather than a constant stream, like the semiconductor-based devices we currently use. Translation: Our computers and smartphones will require 100 times less energy to run, and will last much, much longer before they need a recharge.
The Cota, for the unintiated, is a somewhat nebulous term for Ossia’s wireless charging technology. It comprises a transmitter, a receiver, and software to manage it all. The transmitter, which comes in form factors ranging from an illuminated monolithic white cylinder to a drop ceiling tile, charges Cota-compatible devices using hundreds of omnidirectional antennas that beam radio (RF) waves 100 times a second.
Some of the biggest impact on resource consumption could come from analytics, automation, and Internet of Things advances. These technologies have the potential to improve the efficiency of resource extraction—already, underwater robots on the Norwegian shelf are fixing gas pipelines at a depth of more than 1,000 meters, and some utilities are using drones to inspect wind turbines. Using IoT sensors, oil companies can increase the safety, reliability, and yield in real time of thousands of wells around the globe. These technologies will also reduce the resource intensity of buildings and industry. Cement-grinding plants can cut energy consumption by 5 percent or more with customized controls that predict peak demand. Algorithms that optimize robotic movements in advanced manufacturing can reduce a plant’s energy consumption by as much as 30 percent. At home, smart thermostats and lighting controls are already cutting electricity usage.
Texas produces about four times more wind power than 3rd place California and three times more than 2nd place Iowa. Pretty amazing for Texas, an energy juggernaut that also supplies about 28% of our natural gas and 37% of our crude oil. Texas has surged its wind power capacity 80% to 18,000 megawatts since 2010, with actual wind generation more than doubling over that time.
There are more than 10,000 wind turbines in Texas, and at times last winter, wind supplied 40-50% of the state’s electricity. The Great Texas Wind Boom has all come without much help from legendary Texas oilman T. Boone Pickens, who backed out of his grandiose wind plans in the state.
Texas now produces more wind power alone than 25 U.S. states produce from all power sources combined!
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.
