Whipping a cheap LED PSU into usable shape | EDN

http://www.edn.com/electronics-blogs/benchtalk/4458731/Whipping-a-cheap-LED-PSU-into-usable-shape This interesting article analyses some cheap mains AC to 12V DC power supplies and how thet can be fixed to work OK. With some modifications they can be used to provide power to LED lighting. The writer of this article has a continuing love-hate relationship with Cheap Chinese Chotchkes – in this case, 18W power

Morgan Stanley Predicts Market For Grid Storage Will Explode In Next 3 Years | CleanTechnica

https://cleantechnica.com/2017/08/16/morgan-stanley-predicts-market-grid-storage-will-explode-next-3-years/ A new report authored by Stephen Byrd, a utility and cleantech analyst at Morgan Stanley, and Adam Jonas, its auto analyst, shows that they are bullish on the market for grid storage products. “Demand for energy storage from the utility sector will grow more than the market anticipates by 2019–2020,” the pair says. They predict

Green Energy Will Overtake Fossil Fuels by 2020, Morgan Stanley Analyst States | Big Think

There was no clear answer what they ment by “overtake”, but

Study finds that storage prices are falling faster than PV and wind technologies – pv magazine International

https://www.pv-magazine.com/2017/07/31/study-finds-that-storage-prices-are-falling-faster-than-pv-and-wind-technologies/#.WX_20l9ZtdU.twitter Long-term R&D spending played a critical role in achieving cost reductions. Energy storage projects may bring the cost per kWh of a lithium-ion battery down from $10,000/kWh in the early 1990’s to $100/kWh in 2019, according to a new study written by a research team from University of California and TU Munich in Germany,

Fusion energy pushed back beyond 2050 – BBC News

http://www.bbc.com/news/science-environment-40558758?SThisFB It seems that using fusion energy will be promising looking “around the corner” technology for quite many years according to a new version of a European “road map”. The road map drawn up by scientists and engineers at EUROfusion lays out the technological hurdles to be overcome. We will have to wait until the second half of

Sinewave DC to AC inverter teardown

I have earlier posted DC to AC inverter teardown that showed wat was inside one cheap “modified sinewave” inverter. Now I do a tear-down to a more expensive “true sineware” inverter PI150S from Velleman. This inverter convers 12V DC to nice sinewave 230V 50Hz AC power  (up to 150W). View to front and back. This unit

How smart is it to deploy smart meters on the smart grid? | EDN

In a smart grid architecture, numerous sensors are deployed throughout the grid infrastructure that can monitor, test, and communicate. This may even lead to self-repair and healing/removing and

Nissan launches British-made home battery to rival Tesla’s Powerwall | Business | The Guardian

https://www.theguardian.com/business/2017/may/04/nissan-launches-british-made-home-battery-to-rival-teslas-powerwall Batteries that have powered electric cars around the UK will get a second life providing energy storage for households, with the launch this week of a British-made home battery to rival the one made by Elon Musk’s Tesla. I mentioned Tesla battery a year ago in this blog at  http://www.epanorama.net/newepa/2015/05/02/watch-elon-musk-announce-tesla-energy-in-the-best-tech-keynote-ive-ever-seen-the-verge/

Zinc Battery Breakthrough Could Mean Safer, Lighter Cars and Smartphones – IEEE Spectrum

http://spectrum.ieee.org/energywise/transportation/advanced-cars/zincbased-batteries-can-provide-more-energy-safety-than-liion Rechargeable zinc-based batteries could not only store as much energy as lithium-ion batteries but also be safer, cheaper, smaller and lighter, new research finds. The results suggest zinc batteries could find use in mild hybrids (microhybrids), electric vehicles, electric bicycles, and eventually perhaps smartphones and power grid storage. The researchers are now aggressively testing these batteries and exploring scaling
