Bill Gates says he retired from Microsoft nearly a decade earlier than he intended—here's why

  Bill Gates says he retired from Microsoft nearly a decade earlier than he intended—here's why "If you'd have asked me in my twenties if I'd ever retire early from Microsoft, I'd have told you that you were crazy," says Bill Gates, who ended up leaving Microsoft nearly a decade earlier than he intended."If you'd have asked me in my twenties if I'd ever retire early from Microsoft, I'd have told you that you were crazy," he writes on his blog, Gates Notes.

The answer to this problem , a Bill Gates - backed startup hopes, lies in combining solar power with artificial intelligence. "Today, industrial processes like those used to make cement, steel, and other materials are responsible for more than a fifth of all emissions ," Gates said in a statement.

Problem: Cities around the world constantly need to erect more buildings, but the creation of materials like cement and steel is an enormous contributor to carbon emissions. The answer to this problem, a Bill Gates-backed startup hopes, lies in combining solar power with artificial intelligence.

Heliogen, a California-based startup unveiled on Monday, just announced a breakthrough in solar energy. The company uses mirrors and AI tech to concentrate sun waves, creating solar energy of up to 1,000 degrees Celsius. Heliogen says this is almost double the 565 degrees Celsius reached by other commercial companies in the past.

Energy giants face 35% output cut to hit Paris climate goals: watchdog

  Energy giants face 35% output cut to hit Paris climate goals: watchdog The biggest listed oil and gas giants must slash production by more than a third by 2040 to keep emissions within targets laid out in the landmark Paris climate deal, an industry watchdog said Friday. Climate Tracker, a Britain-based think tank, said that current rates of emissions from the energy majors would see the world's carbon budgets surpassed within decades due to an inexorable rise in oil and gas output. The 2015 Paris deal enjoinsClimate Tracker, a Britain-based think tank, said that current rates of emissions from the energy majors would see the world's carbon budgets surpassed within decades due to an inexorable rise in oil and gas output.

This Bill Gates - Backed Solar Startup Just Had a Breakthrough That Could Cut the World's Carbon Emissions by 20 Percent. He added that cement production alone accounts for 8 percent of global CO2 emissions so a switch to concentrated solar in that industry alone would have a huge impact.

Last year, carbon dioxide emissions rise to 2.4 million pounds per second. As part of the global effort to address climate crisis, Bill Gates as well as oil giants Chevron, BHP, and Occidental are investing in Carbon Engineering, a Squamish, British Columbia-based startup that is hoping to

In other words, Heliogen is able to use solar power for processes like creating steel, cement and petrochemicals that in the past were only doable with fossil fuels or natural gas.

"Today, industrial processes like those used to make cement, steel, and other materials are responsible for more than a fifth of all emissions," Gates said in a statement. "These materials 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. I'm pleased to have been an early backer of [Heliogen CEO] Bill Gross's novel solar concentration technology."

Heliogen uses AI -- or, as it calls it, "advanced computer vision software" -- to calibrate a "large array" of mirrors to reflect sunlight at a single target. The company adds that it'll eventually be able to create solar energy levels of 1,500 degrees Celsius, allowing it to make completely clean hydrogen.

It's unclear when or how much Gates, once again the richest man in the world, invested in the startup. Heliogen declined to comment, and the Bill and Melinda Gates Foundation didn't immediately respond to a request for comment.

Proposed CO2 capture system could reduce truck emissions by 90 percent .
A significant chunk of carbon dioxide emissions come from the transportation sector, and within Europe nearly 40 percent of transport emissions come from trucks. Now, researchers at the Swiss Federal Institute of Lausanne (EPFL) have come up with a new concept for capturing carbon dioxide from truck exhausts which could reduce emissions by up to 90 percent. In a paper published in the journal Frontiers in Energy Research, the researchers propose capturing carbon dioxide from a truck's exhaust pipe and turning it liquid, which is stored in a tank on the vehicle's roof.
