General Electric recently introduced a wind turbine equipped with a storage battery, creating a type of “hybrid” turbine that industry leaders hope will improve the integration of intermittent energy sources onto the grid and reduce the costs of wind power. (more…)
LED lighting remains the hottest area of green patent litigation, with several complaints filed in the last several weeks. Green patent complaints were recently filed in the areas of advanced batteries and solar powered lighting as well. (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…)
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…)
A plastic material is any of a wide range of synthetic or semi-synthetic organic solids that are moldable. Plastics are typically organic polymers of high molecular mass, but they often contain other substances. How about mostly sulfur? A new chemical process can transform waste sulfur into a lightweight plastic that may improve batteries for (more…)
There have been a number of green patent complaints filed recently in such technology areas as compact fluorescent lamps, LEDs, and battery chargers.
Compact Fluorescent Reflector Lamps (more…)
Leyden Energy (Leyden) is a Silicon Valley company that has developed a lithium ion battery that uses imide salts as electrolytes instead of the more commonly used PF6-based electrolytes. Formerly known as Mobius Power, Leyden built it Li-imide battery platform on seed technology from a patent acquired by DuPont. (more…)
U.S. researchers have developed a high-performance, solid electrolyte for use in energy-dense lithium ion batteries that they say is safer than existing liquid electrolytes and could lead to batteries that are five to 10 times more powerful than existing batteries.
While lithium-ion batteries typically utilize liquid (more…)
