Approximately 120 protesters participated in the event at Merrimack Station, the city's news release said, between 1:30 p.m. and 3:30 p.m. ET Saturday. No injuries or damage to property were reported.

If solar energy is truly going to take over from fossil fuels , it needs to be hot enough for not only generating power , but replacing The Bill Gates-backed startup has successfully concentrated solar energy at " breakthrough " temperatures above 1,832F, making it toasty enough to replace fossil

The life-changing moment when solar energy will replace fossil fuels may be closer than we think. Solar power just became the fastest growing source of Fossil fuels are formed by natural processes that take place over the time span of hundreds of millions of years deep underneath the Earth’s surface.

If solar energy is truly going to take over from fossil fuels, it needs to be hot enough for not only generating power, but replacing industrial processes outright -- and even the 1,049F of the best solar concentrator systems wouldn't cut it. Heliogen, however, may have finally cracked that barrier. The Bill Gates-backed startup has successfully concentrated solar energy at "breakthrough" temperatures above 1,832F, making it toasty enough to replace fossil fuels for industrial tasks like producing cement or steel.

The trick is the use of computer vision (aka a form of AI) to align a large array of mirrors as they reflect sunlight on a solitary target. That allows for the kind of accuracy that hasn't been possible until now.

Li-ion batteries: Science 'directly into your hand'

  Li-ion batteries: Science 'directly into your hand' They are omnipresent and essential to navigating modern life. Small, light, rechargeable: lithium ion batteries have revolutionised our world in less than three decades. On Wednesday, John Goodenough, Stanley Whittingham and Akira Yoshino, the inventors of a technology taken for granted by most, got the most prestigious chemistry nod of all: a Nobel Prize. "They created a rechargeable world," stated the Royal Swedish Academy of Sciences, which awards the accolade.

The solar power industry today has revolutionized the way people think about solar power . There have been record amounts of new solar capacity installed in Energy from solar steam is one of the latest breakthroughs in solar power generation; a breakthrough that could replace fossil fuels in

A solar energy tech company founded by serial entrepreneur and inventor Bill Gross — and backed by investors including Microsoft co-founder Bill Gates — says it has developed a way to create concentrated solar energy at temperatures hot enough to replace fossil fuels in industrial

There's still a lot of work to go before the technology enters real-world use. Heliogen achieved the record heat levels the first day of its plant's operation, company founder Bill Gross told CNN. While impressive, it won't immediately translate to a practical solution.

Nonetheless, the implications are huge. As Gates noted in the announcement, industrial processes are responsible for over 20 percent of emissions. If the technology can cut even a portion those emissions, that could help keep global warming in check. Heliogen has greater ambitions, too. It ultimately hopes to reach temperatures of 2,732F, which would be hot enough to create hydrogen and synthetic gas. At that point, you'd have clean energy being used to produce more clean energy -- there would be relatively little need to generate emissions in the first place.

Air pollution in Africa will worsen over the next ten years .
Annual emissions of sulfur dioxide and nitrogen oxides on the continent are expected to double by 2030, compared to 2012 levels. The data also approximates avoidable deaths “attributable to exposure to future fossil fuel use” will reach 48,000 by 2030 with nearly half of those deaths projected to happen in South Africa, Malawi, Nigeria. Emissions from power plants were found to have mortality rates three time higher than from transport-based emissions.© Provided by Quartz Media, Inc.
