Clean-energy startup backed by Bill Gates hopes to replace fossil fuels

Add as a preferred source on Google

A startup backed by Bill Gates has found a way to combine artificial intelligence and solar energy to create extreme heat, essentially replacing the need for fossil fuels. 

The clean-energy company, called Heliogen, has used A.I.-powered mirrors that can generate extreme heat — more than 1,800 degrees Fahrenheit — for the first time commercially, according to a press release. This concentrated solar energy is so hot that it has the potential to replace fossil fuels that are used to make cement, steel, and glass.

“We are rolling out technology that can beat the price of fossil fuels and also not make the CO2 emissions,” said Bill Gross, Heliogen’s founder and CEO, to CNN Business. “And that’s really the holy grail.”

The company is taking the concept of solar energy — specifically concentrated solar energy y— and reflective mirrors to essentially create a massive magnifying glass that would create enough heat to replace the use of fossil fuels by industries that are known to produce harmful CO2 emissions. 

According to the press release, cement alone makes up more than 7% of the world’s CO2 emissions. Heliogen said that its technology could be a major step toward solving climate change.

Because of these promising uses, Heliogen’s processes attracted Gates to get involved as a backer. 

“[Emissions] are everywhere in our lives, but we don’t have any proven breakthroughs that will give us affordable, zero-carbon versions of them. If we’re going to get to zero-carbon emissions overall, we have a lot of inventing to do,” Gates said in the press release. “I’m pleased to have been an early backer of Bill Gross’s novel solar concentration technology. Its capacity to achieve the high temperatures required for these processes is a promising development in the quest to one day replace fossil fuel.”

Other investors in the technology include Swaroop “Kittu” Kolluri from Neotribe Ventures, Patrick Soon-Shiong from NantWorks, and Steve Case from Revolution’s Rise of the Rest Fund. 

A spokesperson from Heliogen told Digital Trends that the technology is commercially available now, and the first commercial deployments are expected in 2020.

Starlink V5 is here, and it’s lighter, smarter, and far more efficient
The next-generation satellite internet kit promises improved efficiency while maintaining high-speed connectivity.
Starlink V4 vs V5

Not every hardware upgrade needs to be about speed. With Starlink V5, SpaceX is betting that a lighter design and lower power consumption matter just as much. The company has officially introduced its next-generation Starlink V5 kit, featuring a smaller and lighter design with significantly improved power efficiency.

If there's one thing budget airlines aren't exactly known for, it's great onboard Wi-Fi. In Frontier Airlines' case, it hasn't offered in-flight internet at all. That's about to change. Frontier Airlines has announced a partnership with SpaceX's Starlink to bring high-speed, low-latency internet across its fleet. Installations will begin in early 2027, making Frontier the first ultra-low-cost carrier in the United States to adopt Starlink's satellite-powered connectivity.

For months, rumors have suggested that OpenAI's first hardware product could be a wearable AI device, or perhaps even the beginning of its long-term smartphone ambitions. As it turns out, the company's first gadget may be something far simpler, yet arguably far more ambitious. It will help control smart-home appliances, play media, answer questions, respond to messages, and tap into the range of capabilities offered by OpenAI's ChatGPT, according to people familiar with the matter.

OpenAI's first AI device could end up being a speaker, following plenty of hype that the company is actually working on a wearable AI device and might even launch a smartphone down the road. According to a Bloomberg report, the speaker will serve as a human-like AI companion that will integrate directly with the smart home ecosystem.
