Stem is a Millbrae, California, startup that sells and leases its battery energy storage system, which is marketed as a way to reduce consumers’ energy bills. Specifically, the company makes a lithium-ion battery connected to analytics software that determines the best times to draw energy from the battery, thereby reducing electricity demand (more…)
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.
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 (more…)
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 (more…)
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 (more…)
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 (more…)
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 (more…)
This proposal involves a simple synergy of government incentives and distributed energy storage applications. But first, I’d like to briefly discuss some of the issues that this solution addresses.
Climate Change (more…)
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 (more…)
