Startup backed by billionaires creates superhot solar power
A mysterious startup reveals a groundbreaking solar energy achievement.
- Heliogen, a startup backed by Bill Gates and Dr. Patrick Soon-Shiong, announces a solar energy breakthrough.
- The company's array of mirrors generated heat of 1,000 degrees Celsius, nearly twice as much as before.
- The startup aims to utilize the technology in industrial processes, significantly reducing gas emissions.
Heliogen, a solar-energy company backed by the the world's richest man, Bill Gates, claims to have made a renewable energy breakthrough. The company's array of mirrors generated a tremendous heat of 1,000 degrees Celsius, showing promise in replacing fossil fuels in major industrial processes.
The company is gearing its tech towards plants that manufacture cement, petrochemicals or steel. The replacement of fossil fuels in such industries could potentially lead to significant reductions in greenhouse gas emissions that have been linked to climate change. Re-powering cement production alone with solar could wipe out up to 7% of carbon dioxide emissions around the world.
The way Heliogen's mirrors work is by concentrating light towards a point on a liquid-filled tower. This heats up the tower, creating thermal energy that can fuel a heat engine. Previous solar thermal systems would only go to 565 degrees, not producing enough power for many industrial operations that have achieved the required heat by burning up fossil fuels.
The company's system of mirrors is also noteworthy for its AI backend, supported by computer vision software that can align the large mirror array with precision to reflect sunlight onto a target. Of course, one wonders if this is going to have military applications.
Heliogen was founded by its CEO – the entrepreneur Bill Gross, who also founded Idealab. He called what Heliogen achieved "a technological leap forward" that can address about 75% of the world's energy demand that is currently not being served by clean energy.
"The world has a limited window to dramatically reduce greenhouse gas emissions," said Gross, adding "With low-cost, ultra-high temperature process heat, we have an opportunity to make meaningful contributions to solving the climate crisis."
Bill Gates, who invested into the company, said in a press release he was "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."
Based in Pasadena, California, the startup is staffed by scientists and engineers from top technical insinuations like Caltech and MIT. Among its other investors is the billionaire Dr. Patrick Soon-Shiong and the venture capital firm Neotribe.

What's next for the startup? Having cracked 1,000 degrees, Heliogen aims to achieve temperates of up to 1,500 degrees Celsius. That amount of heat is necessary to make 100-percent fossil-free fuels like hydrogen or syngas. "If you can make hydrogen that's green, that's a gamechanger," explained Gross to CNN. "Long term, we want to be the green hydrogen company."
What is human dignity? Here's a primer, told through 200 years of great essays, lectures, and novels.
- Human dignity means that each of our lives have an unimpeachable value simply because we are human, and therefore we are deserving of a baseline level of respect.
- That baseline requires more than the absence of violence, discrimination, and authoritarianism. It means giving individuals the freedom to pursue their own happiness and purpose.
- We look at incredible writings from the last 200 years that illustrate the push for human dignity in regards to slavery, equality, communism, free speech and education.
The inherent worth of all human beings<p>Human dignity is the inherent worth of each individual human being. Recognizing human dignity means respecting human beings' special value—value that sets us apart from other animals; value that is intrinsic and cannot be lost.</p> <p>Liberalism—the broad political philosophy that organizes society around liberty, justice, and equality—is rooted in the idea of human dignity. Liberalism assumes each of our lives, plans, and preferences have some unimpeachable value, not because of any objective evaluation or contribution to a greater good, but simply because they belong to a human being. We are human, and therefore deserving of a baseline level of respect. </p> <p>Because so many of us take human dignity for granted—just a fact of our humanness—it's usually only when someone's dignity is ignored or violated that we feel compelled to talk about it. </p> <p>But human dignity means more than the absence of violence, discrimination, and authoritarianism. It means giving individuals the freedom to pursue their own happiness and purpose—a freedom that can be hampered by restrictive social institutions or the tyranny of the majority. The liberal ideal of the good society is not just peaceful but also pluralistic: It is a society in which we respect others' right to think and live differently than we do.</p>

The future of dignity<p>Around the world, people are still working toward the full and equal recognition of human dignity. Every year, new speeches and writings help us understand what dignity is—not only what it looks like when dignity is violated but also what it looks like when dignity is honored. In his posthumous essay, Congressman Lewis wrote, "When historians pick up their pens to write the story of the 21st century, let them say that it was your generation who laid down the heavy burdens of hate at last and that peace finally triumphed over violence, aggression and war."</p> <p>The more we talk about human dignity, the better we understand it. And the sooner we can make progress toward a shared vision of peace, freedom, and mutual respect for all. </p>
Scientists find that bursts of gamma rays may exceed the speed of light and cause time-reversibility.
- Astrophysicists propose that gamma-ray bursts may exceed the speed of light.
- The superluminal jets may also be responsible for time-reversibility.
- The finding doesn't go against Einstein's theory because this effect happens in the jet medium not a vacuum.

Researchers dramatically improve the accuracy of a number that connects fundamental forces.
- A team of physicists carried out experiments to determine the precise value of the fine-structure constant.
- This pure number describes the strength of the electromagnetic forces between elementary particles.
- The scientists improved the accuracy of this measurement by 2.5 times.
The process for measuring the fine-structure constant involved a beam of light from a laser that caused an atom to recoil. The red and blue colors indicate the light wave's peaks and troughs, respectively.
Scientists at Washington University are patenting a new electrolyzer designed for frigid Martian water.
- Mars explorers will need more oxygen and hydrogen than they can carry to the Red Planet.
- Martian water may be able to provide these elements, but it is extremely salty water.
- The new method can pull oxygen and hydrogen for breathing and fuel from Martian brine.
