The UK has been having really nice (hot) weather recently, although there was a brief rainstorm, and possibly lightning during periods over the last few days. We have small pear and plum trees, about 15-20 feet high perhaps. Anyway, the leaves looked really strange today : ( I'm not sure, but I'm wondering if lightning caused it. There are large trees from neighbouring properties that are much taller, and close by. There was some scattering of strange leaves in them too, and generally in the s ...
Murata's small energy devices (UMA series) can be charged very quickly because they can be charged-discharged at a high rate of 10C or more.   If using UMA series as main power supply, you can use the equipment soon by quick charge even when power runs out. In this demo video, further details are provided with comparisons to supercapacitors. UMA series - Application example: Main Power Supply     Related articles: Part 1: Murata to realize Energy Harvesting for IoT - UMA se ...
Researchers at Harvard have created a new organic molecule for flow batteries that promises to be a longer lasting and inexpensive alternative to lithium-ion batteries. This flow battery uses a new organic molecule that’s longer lasting and performs better than other flow batteries outlives and outperforms its predecessors (Photo via Harvard)   Harnessing energy from clean sources is important if we want to replace fossil fuels that are polluting the earth. The problem is we need a w ...
Researchers at Sandia National Laboratories have created a device made out of common materials that can convert heat into electrical power. The rectenna, short for rectifying antenna, catches and converts heat waste into electrical power. (Photo via Sandia National Laboratories)   It’s easy to convert electrical power to heat. We do it on a daily basis without even recognizing it. For example, it happens in your toaster. But when you try to do the opposite – converting heat in ...
The 3D battery is a proof of concept but has the potential to change how batteries work. A mockup of the 3D battery architecture with interpenetrating anode, separator, and cathode each about 20 nanometers in size. (Photo via Cornell University)   Companies are rushing to make smart devices sleeker, more powerful, and faster than last year’s model. But one thing that they still have trouble nailing down is reliable battery life. Battery life is the top concern for consumers and often ...
