Electric cars could be charged at any time and any place.

It could reliably supply energy 99 per cent of the time, at six-times the intensity of solar farms on earth, he said.

Chinese scientists first plan to build and launch small to medium-sized solar power stations to be launched into the stratosphere to generate electricity, between 2021 and 2025.

When a star is born, a chaotic light show ensues.

NASA’s long-lived Hubble Space Telescope captured vivid bright clumps moving through the cosmos at some 1,000 light years from Earth. The space agency called these objects clear “smoking gun” evidence of a newly formed star — as new stars blast colossal amounts of energy-rich matter into space, known as plasma.

Seen as the vivid blue, ephemeral clumps in the top center of the new image below, these are telltale signs of an energy-rich gas, or plasma, colliding with a huge collection of dust and gas in deep space.

A planned US$35-million upgrade could enable LIGO to spot one black-hole merger per hour by the mid-2020s.

This tower is a massive battery — and it could help solve one of renewable energy’s biggest challenges.

Scottish space firm Orbex has unveiled an engineering prototype of a rocket that’s at the heart of plans to develop a UK satellite launch capability.

The company, which is involved in plans to develop the UK’s first spaceport in Sutherland, Scotland unveiled the rocket at the opening of its new headquarters and rocket design facility in Forres in the Scottish Highlands.

Designed to deliver small satellites into Earth’s orbit, Orbex Prime is a two-stage rocket that’s claimed to be up to 30% lighter and 20% more efficient than any other vehicle in the small launcher category. It is also the first commercial rocket engine designed to work with bio-propane, a clean-burning, renewable fuel source that cuts carbon emissions by 90% compared to fossil hydrocarbon fuels.

In the early 1990s, I was lucky enough to get some time on a 60 MeV linear accelerator as part of an undergraduate lab course. Having had this experience, I can feel for the scientists at CERN who have had to make do with their current 13 TeV accelerator, which only manages energies some 200,000 times larger. So, I read with great interest when they announced the publication of the initial design concept for the Future Circular Collider (FCC), which promises collisions nearly an order of magnitude more energetic. The plan, which has been in the works since 2014, includes three proposals for accelerators which would succeed CERN’s current big iron, the LHC.

Until 1993 LEDs could only produce red, green and yellow light. But then Nichia Chemical of Japan figured out how to produce blue LEDs. By combining blue LEDs with red and green LEDs – or adding a yellow phosphor to blue LEDs – manufacturers were able create white light, which opened up a number of new applications. However, these LEDs tend to produce white light with a cool, bluish tinge.

The white-light quantum dots, by contrast, produce a smoother distribution of wavelengths in the visible spectrum with a slightly warmer, slightly more yellow tint, reports Michael Bowers, the graduate student who made the quantum dots and discovered their unusual property. As a result, the light produced by the quantum dots looks more nearly like the “full spectrum” reading lights now on the market which produce a light spectrum closer to that of sunlight than normal fluorescent tubes or light bulbs. Of course, quantum dots, like white LEDs, have the advantage of not giving off large amounts of invisible infrared radiation unlike the light bulb. This invisible radiation produces large amounts of heat and largely accounts for the light bulb’s low energy efficiency.
