Comment Article describes no path to glory (Score 2) 27

Article is bereft of details. I can't think of a way this would work. If the rods are aluminum, er aluminium, they could set up an aluminum air batter, except there's no air. Hmm, maybe use solar panels to get electricity to melt the rods and turn the molten metal all the way into plasma and use that as propellant in some sort of ion engine?

Submission + - Lab Generated Antimatter (popularmechanics.com)

Third Position writes: An international team of physicists have come up with a way to generate antimatter in the lab, allowing them to recreate conditions that are similar to those near a neutron star.

This setup, at Helmholtz-Zentrum Dresden-Rossendorf (HZDR) research laboratory in Germany, involves two high-intensity laser beams that can generate a jet of antimatter, as outlined in a paper published earlier this summer in the journal Communications Physics. That could make antimatter-based research far more accessible for scientists around the world.

Submission + - EV or GasV whats better in a hurricane emergency? (cleantechnica.com) 1

140Mandak262Jamuna writes: On one hand GasV proponents argue:

“It’s 2035, all cars are electric, and the massive Hurricane Iris has hit Louisiana. Much of New Orleans is under water, and emergency workers with their Ford F-150 Lightning electric pickup trucks need to rescue families and pets. But Louisiana has lost power, and the trucks are all dead. The Blessey family, which has lived in New Orleans for generations, want to get out of town to stay with relatives. They can’t set off in their Chevy Bolt EV because they won’t be able to recharge it on the way.”

...

“Gasoline and diesel are winners when natural disasters interfere with the electricity grid,”

(As reported by Cleantechnica, the original Forbes article by Prof Diana Furchtgott-Roth is behind a paywall)

My thoughts are:

But when the grid goes down, gas stations are down too, and they are clogged with long lines of cars and trucks waiting to refuel when the grid comes back. EVs always charge overnight and are likely to be between 80 and 100% full charge when grid goes down. But gas cars like likely to be 50% tank on average with some running near empty. The EV capacity is enough for one full week of normal driving in the city and probably two weeks of emergency trips only mode of driving.

EVs have enough juice to keep your fridge and freezer going for a week, by 2035 they will have actual outlets and inverters to actually let you do it and drive a few more essential appliances. When the grid comes back, these cars quietly charge back to 80% without clogging up the gas station.

The electric pickup trucks of the utilities will have juice to power emergency equipment too, till the grid comes back. All in all, in such an emergency, it is better to own an EV than a GasV.

An actual EV owner who lived through the hurricane, Tonya the Beetle reports in the Reddit EV forum:

This is not meant to be bragging post but rather a counter argument to all the “But what happens when (insert natural disaster) and you can’t drive???” It’s tragic what other people are going through and just because I own an EV doesn’t mean I’m better.

Now to my experience:

I’m between New Orleans and Baton Rouge so Hurricane Ida passed directly over me and did knock out power. It was only for a day though. In that time I simply didn’t make any trips aside from a quick drive down the street and prior to the hurricane I let the car fully charge.

There really wasn’t any point in trying to drive to work or somewhere out of town since most roads were blocked by trees, downed power lines, or someone’s house. Even when power was restored at my house and my work was open again, it was still fairly dangerous to drive on account of traffic lights not working.

By the time power was restored, I could charge anytime I wanted to at my house or at work. On the other hand, gas stations were either out of fuel or had incredibly long lines that stretch out to the main road. Today is the second day I’m commuting to work and so far I have no issues getting fuel since I only need a standard 120v outlet.

For those worried about EVs during a natural disaster, you just aren’t going to travel while there’s no power. Or you’ll just go to a charging station if the power is out for longer than a few days. The road simply wouldn’t be safe to travel after a hurricane and by the time it’s safe, you can simply charge at home instead of waiting in line at a gas station.


Submission + - SPAM: Google co-founder Sergey Brin is reportedly building his own secret airship 1

watsspace writes: Google co-founder Sergey Brin is secretly building his own giant airship inside a NASA hangar, Bloomberg reports today. The craft — which apparently looks like a classic zeppelin — is housed at NASA’s Ames research facility, the publication’s sources say, but it’s not clear whether the airship a prototype for a business venture, or just a passion project for the billionaire.

According to Bloomberg’s sources, Brin’s dirigible is not yet complete, but engineers have already built a metal frame that takes up much of the hangar. Google’s Planetary Ventures division gained access to the Ames facility in 2015, and started using its vast hangars as labs and test areas for new technologies, but the sources note that the airship isn’t a proper Alphabet project.

Brin has been fascinated by airships for a long time, the sources claim, but was inspired to build his own after seeing pictures of the USS Macon — an airship built in the 1930s by the US Navy, and also once housed at the Ames facility. Once the location was secured, and the concept imagined, he assigned Alan Weston — who previously headed NASA’s Ames programs — to lead the project.

THE CRAFT’S METAL SKELETON IS REPORTEDLY COMPLETE
In an age of flying taxis, internet-beaming drones, and self-driving cars, airships might sound a little outdated, but Weston has spoken before about the potential of the vehicles to carry freight at reduced cost. In a 2013 radio interview, he described a helium-filled airship that used a system of “breathing” that would allow it to carry 500 tons of cargo, while remaining “more fuel-efficient than a truck.” Weston — who reportedly performed one of the world’s first bungee jumps — also noted that airships could drop goods off where they were needed, rather than dumping them at ports or airports, necessitating further travel by road or rail.

Weston didn’t respond to Bloomberg’s request for comment, while Brin himself said he “[didn’t] have anything to say about this topic right now.” That statement could be the Google co-founder being cagey and obfuscating his company’s plans to get into the airship business, or it could simply be the sentiment of a man who just really likes blimps. After all, what good is it being a billionaire if you can’t secretly build your own giant airship in a repurposed NASA hangar?

Submission + - China Plans to Build the World's First Waterless Nuclear Reactor (interestingengineering.com) 2

AltMachine writes: Government researchers in China unveiled their design for a commercial molten salt nuclear reactor that is expected to be the first in the world to not utilize water for cooling. The two-megawatt prototype molten salt reactor, powered by liquid thorium instead of uranium, is due for completion next month and the first tests could begin as soon as September. Molten salt reactors are expected to be safer than traditional uranium nuclear reactors, as thorium cools and solidifies quickly in the open air, meaning that a leak would theoretically result in less radiation contamination for the surrounding environment. The concept of a nuclear reactor powered by liquid salt instead of uranium was first devised in the 1940s. However, early experiments struggled to find a solution for problems including the corrosion and cracking of pipes used to transport the molten salts. As the reactor won't need water it can be deployed in desert regions, allowing operators to utilize otherwise desolate spaces in order to provide energy for large populations. The prototype reactor is built in the desert city of Wuwei, in Gansu province.

Submission + - Lab-grown meat company promises profitable product in 18 months (ft.com)

Beeftopia writes: Israeli start-up Future Meat has claimed a huge leap towards commercial viability for its lab-grown chicken, slashing production costs by almost half in just a few months. The company has backers which include Archer Daniels Midland and Tyson Foods. While lab-grown meat is currently only commercially available in Singapore, more than 50 companies are racing to get their product to market.

From the article: "One of the big costs for cultivated meat companies has been the nutrient for the meat cells, and cutting the cost of this 'feed' has been key to reducing the cost of production. Future Meat has successfully found a way to do this, said Sanjeev Krishnan, chief investment officer at S2G, a US agri and food tech venture capital group that has invested in the business. The start-up 'is scaling production in a capital-efficient way', he said."

I was supposing at one point that it would be cool to see if you could focus naturally occurring muons using quadrupole magnets (simple permanent) so that a large area array could pull in lots of muons and focus them in on a small area. The goal being to keep it as simple as possible but one complication would be you probably would need to do this in a vacuum chamber.

They also have it so that for each coordinate that your machine moves the knife, it must make a round trip to their server in order to encrypt the coordinates that the cutter uses. (I heard that they now have an offline version). I ordered one of these on Amazon before realizing how horribly they treat their customers. Needless to say, after it arrived I immediately returned it for a full refund. That was a year and a half ago. Since then I bought a Silhouette and can hack it as desired.
