The droplet-based electricity generator has a high energy-conversion efficiency and power density thousands of times bigger than its counterparts. The developers hope the tech will help to tackle the ...

Dear EarthTalk: What's the story with LED light bulbs that are reputed to be even more energy-efficient than compact fluorescents? — Toby Eskridge, Little Rock, Ark. Perhaps the ultimate "alternative ...

Why is Christian Science in our name? Our name is about honesty. The Monitor is owned by The Christian Science Church, and we’ve always been transparent about that. The Church publishes the Monitor ...

Generating electricity from raindrops efficiently has gone one step further. A research team led by scientists from the City University of Hong Kong (CityU) has recently developed a droplet-based ...

The go-to bulb in the GE HD collection, offering soft, warm, and crystal-clear light quality. GE has appropriated the phrase “high definition” from the TV industry and applied it to a new line of dumb ...

(Nanowerk News) Hydropower is nothing new, but harnessing the energy in waves, tides and raindrops has remained elusive because conventional technology does not efficiently convert low-frequency ...

Static electricity from friction generates a small amount of energy, but it can be usefully applied to small devices like charging smartwatches. A Korean research team has now developed a ...

The numbers you see on the box don't always work out in real life. LED bulbs do last longer, but those claims about five to 10 years are estimates based on internal testing -- and companies are always ...

A research team led by scientists from City University of Hong Kong (CityU) has recently developed a new form of droplet-based electricity generator (DEG). It features a field-effect transistor ...

KYIV, Jan 30 (Reuters) - Ukrainians were urged on Monday to swap old light bulbs for free energy-efficient LED bulbs under a scheme intended to ease an energy shortfall caused by Russian attacks.
