Norwegian company Wind Catching Systems is developing a floating, multi-turbine technology for wind farms that could generate five times the annual energy of the world’s largest, single wind turbine. This increased efficiency is due to an innovative de…

What if your smartphone or laptop started charging as soon as you walked in the door? Researchers have developed a specially built room that can transmit energy to a variety of electronic devices within it, charging phones and powering home appliances …

An anonymous reader quotes a report from New Scientist: Wooden floors infused with silicon and metal ions can generate enough electrical power from human footsteps to light LED bulbs. Researchers hope that they could provide a green energy source for h…

Last year, 42% of new electricity generation capacity in the U.S. came from land-based wind energy — more than from any other source — according to numbers in a series of reports from the Department of Energy (DOE) this week. By contrast, solar amoun…

“In 2016, the International Renewable Energy Agency estimated that as much as 78 million tons of solar-panel waste will be generated by 2050,” writes a Bloomberg columnist, adding that that’s “almost certainly an undercount…” So what will happen to a…

世界のガス価格が高騰しているそうだ。日経新聞によると、夏は天然ガス価格が安定しやすいとされているが、今年は経済回復の傾向が強まったこと、脱炭素の動きが加速していることなどから需要が増えたことに加え、供給面も弱まってきていることから需要が厳しくなっているようだ。欧州のガス価格に関しては歴史的な水準に達しているとしており、電気事業連合会の記事によれば、どこまで上昇するのかわからないとしている。また中国などアジア地域ではLNGが取り合いとなってるそうだ（日経新聞、電気事業連合会、東京新聞）。国内でも電力・…

For a fraction of a second, 10 quadrillion watts of fusion power were produced this month by researchers at Lawrence Livermore National Laboratory.

The author of The Star Builders: Nuclear Fusion and the Race to Power the Planet explains what might h…

シアトル・タコマ国際空港 (SEA) で23 日、ニューオリンズから到着したアラスカ航空 751 便の機内で火災が発生し、乗客・乗員が緊急避難する事態となったそうだ (SEA のツイート、 The Seattle Times の記事、 GeekWire の記事、 The Verge の記事)。

当初 SEA では貨物室内で火災が発生したと説明していたが、のちに客室内での発生と訂正された。アラスカ航空によれば火災の原因は携帯電話のバッテリーであり、乗務員が耐火バッグで消火したが、煙により緊急脱出スラ…

Tesla wants to sell electricity directly to customers in Texas, according to an application filed by the company this month with the Public Utility Commission there. From a report: The application follows the start of a big battery build out by Tesla i…

Scientists in Germany have developed what they say is the smallest microsupercapacitor in existence. It’s smaller than a speck of dust, safe for use in the human body, and can deliver similar voltage to a AAA battery. Prior to this breakthrough, the sm…
