The world’s poorest countries are investing more in LED lighting, energy storage, and other off-grid electricity technologies, according to a report by Larry West.
In cities across the United States, LED lighting like LED wall packs or LED bollards help cut energy costs, carbon dioxide emissions, and excessive light
Picking up where we left off, I now have a preliminary draft of the Patent PR study (available here) and a better sense of how the subject matter of clean tech press releases fits into the full universe of patent PR.
The relative proportion of subject matter categories for the full data set, i.e., for press releases
Last month, at the U.S. Marine Corps’ Mojave Desert combat training center, some of the military’s best and brightest gathered to test the latest in energy-saving gear. The gadgets sound like ones that a green scientist might dream up if set loose in Q’s lab — collapsible solar arrays, electricity-generating backpacks, hybrid power systems using
A previous post reported on the acquisition of Beacon Power, formerly the largest flywheel player, after the company went bankrupt.
One of the technical hurdles faced by designers of these whirling rotational energy storage devices is that spinning masses have a natural “wobble.” Most flywheel designers have employed
General Electric recently announced it had started testing the prototype of what it calls the world’s most efficient high-output wind turbine. The new 2.5-120 is being tested in Wieringermeer, Netherlands.
The 2.5-120 harnesses the power of the Industrial Internet to analyze tens of thousands of data points
One of the problems with wind power is that when there is no wind then there is no power. Offshore wind could provide abundant electricity — but as with solar energy, this power supply can be intermittent and unpredictable. A new approach from researchers at MIT could mitigate that problem, allowing the electricity generated by floating wind
LightSail Energy (LightSail) is a Berkeley, California, company that has developed compressed air energy storage technology which may be used for grid-scale storage.
The company’s central innovation is the injection of a mist of water spray into a compressed air system so
Will new technologies democratize energy much the way the Internet did information?
Industry movement seems to point in that direction with the rise of the smart grid, time-of-day pricing, distributed solar, and the electric vehicle. Together these technologies offer a vision of a less centralized energy system, one where communities and households ‘vote in’ or shape the
The electrical grid is a complex network connecting thousands of power sources with millions of consumers all across the U.S. While producing enough power to supply the energy needs of a nation is an extremely difficult task, just as challenging, if not more so, is the need to balance supply and demand on the grid.
Storing energy produced during off-peak times is one of the challenges the renewable energy industry faces and which will be exacerbated as more intermittent forms of electricity generation enter the grid. One of the latest propositions to solve the problem has surfaced in the UK, via the Institution of Mechanical Engineers, who said that turning air into liquid
I’ve been thinking about my up-coming meeting with Dr. Raj Pachauri, who, among other things, serves as the chairman of the Intergovernmental Panel on Climate Change (IPCC). Pondering this in advance of the meeting, I wonder what I would do, given the power, to deal with climate change.
Eric Isaacs, director of Argonne National Laboratory, a multidisciplinary research center in the American midwest, talks about alternative energy solutions. He emphasizes the research on how to improve energy storage, particularly lithium-based battery technology.
“Twenty years ago we had some great innovations
In a previous post, I wrote about the New Energy Symposium held last month in New York City. The first day of the event featured a startup quick pitch competition, and the three winners of the competition were recently announced.
They are, in alphabetical order, Dynamo Micropower,
