This holiday light display brought to you by an electric eel named Miguel Wattson

[embedded content] If you happen to enjoy the festive light display at the Tennessee Aquarium over the holidays, you can thank a certain electric eel for it. Although the eel in question probably doesn’t care either way. Miguel Wattson is…

Hot electrons harvested without tricks

(University of Groningen) Semiconductors convert energy from photons into an electron current. However, some photons carry too much energy for the material to absorb. These photons produce ‘hot electrons’, and the excess energy of these electrons is converted into heat. Materials scientists have been looking for ways to harvest this excess energy. Scientists from the University of Groningen and Nanyang Technological University (Singapore) have now shown that this may be easier than expected.

New catalyst efficiently produces hydrogen from seawater

Seawater is one of the most abundant resources on earth, offering promise both as a source of hydrogen and of drinking water in arid climates. Now researchers have reported a significant breakthrough with a new oxygen evolution reaction catalyst that, combined with a hydrogen evolution reaction catalyst, achieved current densities capable of supporting industrial demands while requiring relatively low voltage to start seawater electrolysis.

‘Messy’ production of perovskite material increases solar cell efficiency

(University of Cambridge) Discovery means simpler and cheaper manufacturing methods are actually beneficial for the material’s use in next-generation solar cells or LED lighting.

MIT Engineers Unveil ‘Revolutionary’ Carbon Capture Tech to Absorb CO2 Using ‘Significantly’ Less Energy and Money

A new method of removing carbon dioxide in any concentration, was unveiled by MIT that uses significantly less energy, and at a lower cost.

EV Motor Control 101

Editor’s Note: The team at Mountain Pass Performance are doing some truly cutting edge work and research on EV motor controls. They put together a comprehensive post on EV motors with some help from Chris Brune at Rinehart Motion Systems and were nice enough to let us repost it here.
