Morocco Turns on What will Become the World’s Largest Solar Power Plant

As oil was to Saudi Arabia, could solar be to Morocco?

Morocco has turned on its enormous solar power plant in the town of Ourrzazate, on the edge of the Saharan desert. The plant already spans thousands of acres and is proficient of generating up to 160 megawatts of power. It’s already one of the largest solar power grids in the world, capable of being seen from space. And it’s only going to get bigger.

The present grid, called Noor I, is just the first phase of a planned project to bring renewable energy to millions living in Morocco. It will soon be followed by expansions, Noor II and Noor III, that will add even more mirrors to the present plant. Once the project is finished around 2018, the whole grid will cover 6,000 acres. It will be capable of producing up to 580 megawatts of power, comparable to that of a small nuclear reactor.

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

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

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.

Unlike nuclear fission, in which the nucleus of an atom is split into smaller parts, nuclear fusion creates a single heavy nucleus from two lighter nuclei. The resulting change in mass produces a massive amount of energy that physicists believe can be harnessed into a viable source of clean energy.

German plasma success raises nuclear fusion hopes

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

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.

Nuclear fusion could prove to be a clean, inexhaustible energy source. But humans are still a ways from successfully building a reactor that could power a small town, let alone entire cities. But now, we’re one step closer.

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

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.

In 2013, a paper published in the journal Bioresource Technology reported that algal fuels can cut carbon dioxide emissions by 50 to 70 percent. It’s also more efficient than other biofuels, like those derived from corn. The US Department of Energy says that algae could produce up to 60 times more fuel per acre than land-based plants.

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

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.”

Stephen Hawking and his colleagues have come to a possible answer. Think of your television. You watch shows and movies and you are not thinking how unrealistic the movie is because it is on your two dimensional screen. The two dimensions represent information which is perceived by your brain as an accurate portrayal of the three dimensional universe. In short, the three dimensional universe is captured in two dimensions; reality becomes a hologram. Out reality could be nothing more than a television show if we extend Hawking’s Theory to the entire universe.
