The solar-cell pushers have been touting for quite some time the fact that the costs of solar cells have now nearly reached capital-cost parity with other sources of electrical energy. Parity is assumed to be a dollar a peak watt of capacity or thereabouts. But is that really true?
Nordson EFD has developed a non-contact dispense valve for precision jetting of low viscosity flux onto solar cell bus bars. Operating at speeds up to 500Hz/sec, the Square Wave 745NC valve meets the photovoltaic industry's need to deposit continuous lines of microdots on the solder-coated metal ribbons that connect adjoining PV wafers.
Korean researchers from Ulsan National Institute of Science and Technology (UNIST), S. Korea, developed a novel bio-inspired composite electrocatalyst outperforming platinum. This research work was published on June 25, in the journal Nature Communications. (Title: Promotion of Oxygen reduction by a bio-inspired tethered iron phthalocyanine carbon nanotube-based catalyst).
In chemical reactions, left and right can make a big difference. A "left-handed" molecule of a particular chemical composition could be an effective drug, while its mirror-image "right-handed" counterpart could be completely inactive. That's because, in biology, "left" and "right" molecular designs are crucial....
Semtech Corporation introduced the SX1272, the first product in a new long-range RFIC platform that boosts the transmission range of the devices to up to 15 kilometers (km). This device integrates Semtech’s new LoRa (long range) modulation technology to enable drastic range improvements over alternative modulation methods.
Most efforts at improving solar cells have focused on increasing the efficiency of their energy conversion, or on lowering the cost of manufacturing. But now MIT researchers are opening another avenue for improvement, aiming to produce the thinnest and most lightweight solar panels possible.
Murata announced the compact DMR20-10-DCM "nanoMeter" self-powered auto-ranging DC voltmeter designed for mounting in an industry-standard "oiltight" 30 and 30.5 mm / 1.2 inch round panel cutout. Occupying minimal space, the round voltmeter has a 7.6mm / 0.3 inch four-digit LED display and is self-powered.
Amyris and Total announce successful demonstration flight with renewable jet fuel during Paris Air ShowJune 20, 2013 9:15 am | News | Comments
Amyris, Inc. and Total announced today a successful demonstration flight at the Paris Air Show using a breakthrough technology that converts plant sugars into renewable jet fuel. The Airbus A321 aircraft powered by two Snecma CFM56 jet engines flew from Toulouse to Paris with a blend of renewable jet fuel produced by Amyris and Total.
For only the second time since 2006, global investments in renewable energy in 2012 failed to top the year before, falling 12% mainly due to dramatically lower solar prices and weakened US and EU markets. However, 2012 was the second highest year ever for renewable energy investments, which total $1.3 trillion since 2006.
The Smart Grid is coming. It is needed in order to raise or lower prices for consumers depending on the time of day. It is needed to control consumer loads to better integrate intermittent alternative energy into the grid (industrial loads are already demand controlled by the grid operator depending on the type of service contract they have).
The market for smart grid sensors in North America is expected to grow dramatically during the next two years, according to a new study published by IMS Research, now part of IHS. The report, entitled “The North American Market for Smart Grid Sensors – 2013,” shows a major change is occurring in the feeder line sensing market in North America....
Japan’s solar installations surged by a stunning 270 percent (in gigawatts (GW)) in the first quarter of 2013, positioning the country to surpass Germany to become the world’s largest photovoltaics (PV) market in terms of revenue this year. Although Japan is forecast to install fewer GW than China (which is forecast to be the largest market in GW installation terms) in 2013...
The worldwide transition to ever smarter mobile devices, including phones or connected tablets, has obliterated the line that once existed between phones and computing devices. Today’s multitasking devices enable work, finance, entertainment and social interaction on the go like never before.
Being "green" has gone from a technical effort to economically reduce energy use and avoid waste where such avoidance makes sense to actively reducing our effectiveness to show how committed we are to the Green Religion. And there is so much of this going on. In my opinion we would be much better off worshiping trees. Or cows.
There is a push on to make buildings more energy efficient. This is in part being accomplished by making them meet LEED Standards. What does LEED stand for? Leadership in Energy and Environmental Design. LEED promises to "Reduce harmful greenhouse gas emissions".
It may be possible soon to charge cell phones, change the tint on windows, or power small toys with peel-and-stick versions of solar cells, thanks to a partnership between Stanford University and the U.S. Department of Energy's National Renewable Energy Laboratory (NREL).
A solar-powered plane that has wowed aviation fans in Europe is set to travel across the United States with stops in Phoenix, Dallas, Washington, D.C., and New York, organizers of the trip announced Thursday.
Five months have passed since Superstorm Sandy, and legislators are nipping around the edges of bolstering the fuel distribution system so more gas can get to the consumer in the case of a widespread power outage or other state of emergency.
I’ve heard for years that “soon we’ll have solar panels on everything.” To be honest, I’ve never paid much attention to the hype because these magical solar panels that can fit on and inside everything never seemed to materialize commercially, or if they did they were always way too expensive for the everyday consumer, or maybe just for me.
This is not an article about the environment. This is not an article about oil. This is an article about the long-term future of human civilization. Are you with me so far? Are you in favor of human civilization having a future, not just for another hundred years, but for thousands ... tens of thousands?
President Barack Obama is pushing the U.S. Congress to authorize $2 billion over 10 years for federally funded research into clean energy technologies that can wean automobiles off oil. Obama proposed the idea of an energy security trust last month in his State of the Union address....
I got an e-mail from a friend recently railing against what he called (loosely translated by me) "Green Energy Pirates". Let me quote one sentence from his e-mail. "There is a whole slew of companies that move from subsidy to subsidy globally and then abandon 'green projects' when the subsidies dry up."
The IET interviews Andrew Bissell an owner and driver of a Tesla, filmed at the University of Newcastle, UK, 3 May, 2012. This interview covers range anxiety, charging the car, why people should buy an electric vehicle and an owner's perspective on the drivers needed for mass adoption.
New and improved technology for measuring power quality in smart grids could save 839k tonnes of carbon and bring £250 million annual GVA in economic benefit. The technology has been developed by scientists at the Centre for Carbon Measurement, part of the National Physical Laboratory (NPL), the UK's National Measurement Institute.
More than one-third of U.S. nuclear power plants suffered safety-related incidents over the past three years, and nuclear regulators and plant operators need to improve inspections to prevent such events, the Union of Concerned Scientists (UCS) said in a report on Thursday.
