- American households might use EVs as backup power with this bidirectional charger. Homeowners can also schedule charging sessions when electricity rates are low, store that power in their EV, and discharge it to power their homes when electricity rates are higher. Quasar 2 provides up to 11.5 kW. https://www.greencarreports.com/news/1134639_american-households-might-use-evs-as-backup-power-with-this-bidirectional-charger 102 comments energy
- Chinese American Jia Liu and her team of US researchers have engineered neurons to make Electrically Conductive Materials to allow them to build artificial structures. It 'could be used to improve (enhance) connections with implants, such as those used to control next-generation prosthetics.' https://www.news-medical.net/news/20200320/genetically-modified-neurons-could-enhance-function-of-clinical-implants.aspx 3 comments artificial
- Physicists from MIT designed a pocket-sized cosmic ray muon detector that costs just $100 to make using common electrical parts, and when turned on, lights up and counts each time a muon passes through. The design is published in the American Journal of Physics. https://news.mit.edu/2017/handheld-muon-detector-1121 1061 comments science
- Toyota North American CEO: We're betting big on fuel cell cars. "Why? Because "it's an on-demand electric vehicle," Lentz said. "Rather than having a large heavy battery that takes a while to charge, you basically use hydrogen to produce electricity and water vapor." http://tech.fortune.cnn.com/2014/05/20/toyota-ceo-jim-lentz-brainstorm-green/ 4 comments technology
