O.o circa 2016.
MIT has been developing a small fusion reactor prototype, three of which could power the City of Boston if they were fully built. Though the project lost federal funding for its current fusion device, the school plans to press ahead on building a new, more advanced prototype.
Last week, the Department of Energy gave a commercial company the green light to test fuel made from spent uranium.
You know what this world needs now… aside from love, sweet love, of course? Less nuclear waste. But it also seemingly needs more and more power, which nuclear would be great at providing, if not for all that pesky waste and those darn radioactive meltdowns that can happen when you go around splitting atoms (fission). Which is where nuclear fusion was supposed to help out, but generating Sun-like temperatures to recreate the processes that power our Earth-powering star have kept that technology at bay.
Well, we may be a lot closer to utilizing the power of fusion, thanks to the revolutionary thinking of HB11, a company that recently secured patents in the U.S., Japan, and China for just that kind of forward thinking technology. And if all goes according to plan, it could just change the world of electricity generation as we know it.
A key hurdle facing fusion devices called stellarators—twisty facilities that seek to harness on Earth the fusion reactions that power the sun and stars—has been their limited ability to maintain the heat and performance of the plasma that fuels those reactions. Now collaborative research by scientists at the U.S. Department of Energy’s (DOE) Princeton Plasma Physics Laboratory (PPPL) and the Max Planck Institute for Plasma Physics in Greifswald, Germany, have found that the Wendelstein 7-X (W7-X) facility in Greifswald, the largest and most advanced stellarator ever built, has demonstrated a key step in overcoming this problem.
Cutting-edge facility
The cutting-edge facility, built and housed at the Max Planck Institute for Plasma Physics with PPPL as the leading U.S. collaborator, is designed to improve the performance and stability of the plasma—the hot, charged state of matter composed of free electrons and atomic nuclei, or ions, that makes up 99 percent of the visible universe. Fusion reactions fuse ions to release massive amounts of energy—the process that scientists are seeking to create and control on Earth to produce safe, clean and virtually limitless power to generate electricity for all humankind.
Scientists in Australia are making some astonishing claims about a new nuclear reactor technology. Startup HB11, which spun out of the University of New South Wales, has applied for and received patents in the U.S., Japan, and China so far. The company’s technology uses lasers to trigger a nuclear fusion reaction in hydrogen and boron—purportedly with no radioactive fuel required. The secret is a cutting-edge laser and, well, an element of luck.
The laser doesn’t heat the materials. Instead, it speeds up the hydrogen to the point where it (hopefully) collides with the boron to begin a reaction.
The process even skips the “need for a heat exchanger or steam turbine generator” and can feed an electrical flow “almost directly into an existing power grid,” according to the company’s statement.
No nuclear waste, no steam, zero chance of a nuclear meltdown. It almost sounds too good to be true — but the startup still has a lot to prove. McKenzie admitted himself he doesn’t know if or when the startup’s idea could be turned into a commercial reality.
“I don’t want to be a laughing stock by promising we can deliver something in 10 years, and then not getting there,” he told New Atlas.
“We are sidestepping all of the scientific challenges that have held fusion energy back for more than half a century,” says the director of an Australian company that claims its hydrogen-boron fusion technology is already working a billion times better than expected.
HB11 Energy is a spin-out company that originated at the University of New South Wales, and it announced today a swag of patents through Japan, China and the USA protecting its unique approach to fusion energy generation.
Fusion, of course, is the long-awaited clean, safe theoretical solution to humanity’s energy needs. It’s how the Sun itself makes the vast amounts of energy that have powered life on our planet up until now. Where nuclear fission – the splitting of atoms to release energy – has proven incredibly powerful but insanely destructive when things go wrong, fusion promises reliable, safe, low cost, green energy generation with no chance of radioactive meltdown.
O.o.
The device’s maker says it could produce neutrons — a type of ionising radiation.
