People eat sandwiches to give themselves energy. A new study explains how to get electricity from those sandwiches without going to the bother of eating them. The study is: “Sandwich as a Triboelectric Nanogenerator,” Jingyi Jiao, Qixin Lu, Zhonglin Wang, Yong Qin, and Xia Cao, Nano Energy, vol. 79, no. 105411, September 2020. The authors, […]

Hula-Hoops as electrical generators [studies]
“We designed and implemented a human-powered generator which could provide large electricity by using and measured a human metabolic energy expenditure needed to operate it.“ – explain researchers Yoon-Ho Lim, Jeong-Jin Yeo, Mun-Ho Ryu and Yoon-Seok Yang of Chonbuk National University, Korea, who have, between them, developed a hula-hoop inspired human-powered electric generator. Their experimental […]
Jaw power (new patent)
“As electronics devices become increasingly powerful and smaller, powering these devices has become a significant concern. It may be troublesome to find compatible power sources when a user is frequently mobile and devices often require multiple recharges per day.” There’s now a new energy-harvesting solution to the problem – the chew-powered fake-tooth piezoelectric generator. It’s […]
The ACME Country-Music Generator
Amazing as it may seem, algorithmic methods for generating music go back at least as far as 1757 (see: Musikalisches Würfelspiel). But algorithmic methods for generating US ‘Country Music’ are far more recent. Indeed, Jim Suruda and professor Norman Carver of the Department of Computer Science, Southern Illinois University, Carbondale IL, USA, are still in […]
