Germany is getting closer to nuclear fusion—the long-held dream of unlimited clean energy

Posted by in categories: nuclear energy, particle physics

German scientists today will set about the first steps towards what has become the Holy Grail of energy—nuclear fusion, which has the potential for unlimited amounts of clean power. There are a number of challenges to harnessing this power —researchers need to build a device that can heat atoms to temperatures of more than 100 million °C (180 million °F).

After almost nine years of construction work and more than a million assembly hours, researchers from the Max Planck Institute in Greifswald are set to do just that by heating a tiny amount of hydrogen until it becomes as hot, hopefully, as the center of the Sun.

Researchers are keen to tap into the incredible amount of energy released when atoms join together at extremely high temperatures in the super-hot gas known as plasma. Today’s test will not produce any energy, just the plasma—a different state of matter created at extremely high temperatures. German chancellor Angela Merkel, who has a doctorate in physics, will reportedly attend.

Scientists in Germany Take a Major Step Towards Nuclear Fusion

Posted by in categories: nuclear energy, particle physics

Excellent news!


Physicists in Germany have used an experimental nuclear fusion device to produce hydrogen plasma in a process similar to what happens on the Sun. The test marks an important milestone on the road towards this super-futuristic source of cheap and clean nuclear energy.

Earlier today in an event attended by German Chancellor Angela Merkel (herself a PhD physicist), researchers from the Max Planck Institute in Greifswald turned on the Wendelstein 7-X stellarator, an experimental nuclear fusion reactor. (Actually, the researchers let Merkel do the honors.) This €400 million ($435 million) stellarator is being used by physicists to test the technical viability of a future fusion reactor.

German plasma success raises nuclear fusion hopes

Posted by in categories: nuclear energy, particle physics

A German nuclear fusion experiment has produced a special super-hot gas which scientists hope will eventually lead to clean, cheap energy.

The helium plasma — a cloud of loose, charged particles — lasted just a tenth of a second and was about one million degrees Celsius.

It was hailed as a breakthrough for the Max Planck Institute’s stellarator — a chamber whose design differs from the tokamak fusion devices used elsewhere.

Germany just fired up a monster machine that could revolutionize the way we use energy

Posted by in categories: nuclear energy, physics

On Thursday, the Max Planck Institute for Plasma Physics fired up a monster machine that it hopes will change the world.

The machine is called the Wendelstein 7-X, or W7-X for short. It’s a type of nuclear-fusion machine called a stellarator and is the largest, most sophisticated of its kind.

Why Algae Could Be the Greatest—and Trickiest—Fuel Source of All

Posted by in categories: climatology, nuclear energy, sustainability

I recall when Venter made the first synthetic unique life form he said biofuels and algae that soaks up carbon dioxide would come out of it. Feels like it has been slow going but here is a why and why no item and please read the comments too as they are also informative.


From powering airplanes to replacing nuclear energy, algae has been touted as a green energy miracle. So if our waterways are already filled with the stuff, why isn’t it filling the world’s skies with biofueled planes? Algae is a tricky creature that presents a lot of challenges and misconceptions. Here’s why it’s difficult to harness—and why it could big a big payoff.

As we previously reported, algae is a fuel source that’s vastly more eco-friendly than oil, and will be crucial as we head into a future filled with climate change and depleting fossil fuels.

Stephen Hawking’s Legacy Could Be ‘Holy Grail’ Of Physics: Combining Gravity And Quantum Mechanics At Black Hole Horizons

Posted by in categories: cosmology, neuroscience, nuclear energy, particle physics, quantum physics, sustainability

Interesting…


To suggest that quantum mechanics and gravity are on the verge of being reconciled would be, to the physics world at least, as significant as the discover of splitting the atom. While splitting the atom might have led to the nuclear bomb, it also led to the technology of nuclear power, i.e. nuclear fission, which, if harnessed properly, creates a renewable and sustainable energy resource. The problem has always been that quantum mechanics — the rules that govern sub-atomic particles — and gravity, the rule that governs mass as we know it (the stuff we can touch and feel), do not agree with each other. The question has always been, what is it that “unifies” these two theories? Is quantum mechanics God playing dice, as Einstein suggested?

“God doesn’t play dice with the universe.”

This new laser could make things hotter than the centre of the Sun almost instantly

Posted by in categories: materials, nuclear energy, sustainability

Scientists have proposed a laser model that can could heat materials to temperatures hotter than the centre of the Sun in just 20 quadrillionths of a second. That’s 10 million degrees Celsius almost instantaneously.

The discovery brings us one step closer to the dream of achieving thermonuclear fusion energy — the production of clean, sustainable, and limitless energy using the same process the Sun uses to produce heat.

The challenge in harnessing the energy from thermonuclear fusion is that, as with any form of energy production, you need to get out more than you put in, and heating things to temperatures that rival the centre of the Sun is not easy. Current laser technology has failed to make the heating process efficient enough to make the process worthwhile, but a team from Imperial College London in the UK has come up with a model for a laser than can heat things about 100 times faster than the world’s most powerful fusion experiments.
