Golf’s loss is solar’s gain in Japan

Old golf course land is to become solar farms, according to Kyocera, which is working with partners on the conversions.

The most recently announced is a 23MW power plant on an abandoned golf course in Kyoto Prefecture, which will generate an estimated 26GWh/year.

“Over-development of golf properties during…

Narrow beam angles from small LED packages

Following research at Sheffield-based LED packaging firm Litecool, narrow beam angles from LED packages without secondary optics or reflectors look closer.

The proof-of-concept device produced a beam with 50% of light in 36 degrees, and over 90% efficiency.

“Most package manufacturers design their LED packages for maximum…

Molecule opens window on single-electron transistors

An international team has made single-electron transistors – a transistor from a molecule of phthalocyanine and twelve indium atoms.

An alternative to ‘single electron’ transistors made on fabricated quantum dots – which are sensitive to one electron leaving or joining, but typically have hundreds of electrons – this transistor is simple and…
