A secretive startup backed by Bill Gates has achieved a solar breakthrough aimed at saving the planet.Heliogen, a clean energy company that emerged from stealth mode on Tuesday, said it has discovered a way to use artificial intelligence and a field of mirrors to reflect so much sunlight that it generates extreme heat above 1,000 degrees Celsius.Essentially, Heliogen created a solar oven — one capable of reaching temperatures that are roughly a quarter of what you'd find on the surface of the sun.The breakthrough means that, for the first time, concentrated solar energy can be used to create the extreme heat required to make cement, steel, glass and other industrial processes. In other words, carbon-free sunlight can replace fossil fuels in a heavy carbon-emitting corner of the economy that has been untouched by the clean energy revolution."We are rolling out technology that can beat the price of fossil fuels and also not make the CO2 emissions," Bill Gross, Heliogen's founder and CEO, told CNN Business. "And that's really the holy grail."Heliogen, which is also backed by billionaire Los Angels Times owner Patrick Soon-Shiong, believes the patented technology will be able to dramatically reduce greenhouse gas emissions from industry. Cement, for example, accounts for 7% of global CO2 emissions, 1328

A suspect is in custody after he allegedly stabbed five people at a workplace in Tallahassee, Florida.The suspect, 41-year-old Antwann D. Brown, was arrested almost immediately after police arrived on the scene at Dyke Industries.Investigators say Brown is an employee of Dyke Industries. Police claim he clocked in at 8 a.m. local time. He quickly got into a verbal dispute and was asked to leave at 8:20.That when, according to police, he "spontaneously" stabbed a total of five employees with a folding knife.Tallahassee nterim Chief Steve Outlaw said that after Brown attacked, employees held Brown at bay by grabbing anything they could find in the office. When Brown ran away from the scene, arriving officers quickly apprehended him about a block away from Dyke Industries, 10 to 15 minutes after the first stabbing.Outlaw said it appeared Brown only sought out certain victims and had no pending employment issues at his job. At this time, police don't have a motive and don't believe the incident was related to the anniversary of the Sept. 11 attacks."You can't help but wonder, on the first flush when you hear that, is this related to the anniversary? You just can't help but wonder that," Outlaw said. "Very, very sad occasion... But fortunately, from what we can tell, there was no relationship to the anniversary."Police say that Brown has a prior record connected to a violent incident in Georgia, but indicated that the incident was not recent. According to the Florida Department of Corrections, Brown's criminal history includes drug dealing and grand theft dating back to 1996. He was released from prison in July 2009.Tallahassee Memorial HealthCare says one of the victims is in serious condition, two are in fair condition, and two others are in good conditionThis story was originally published by 1834

A top White House adviser indicated Tuesday afternoon that the administration might try to find a way to keep goods moving across the US-Mexico border -- just before President Donald Trump told reporters that he remains "totally prepared" to follow through on his threat to shut down all traffic over undocumented immigration.The apparent contradiction stood out on a day of wild moves by the Trump administration, which is navigating the border crisis as Trump is fueling a renewed debate on the future of American health care with his support for a legal challenge against Obamacare.Trump has threatened to close the border this week as a way to stem illegal immigration. But if a shutdown blocks trade, too, it would disrupt 740
