Opinion | They Stormed the Capitol. Their Apps Tracked Them
Your smart phone will track your movements if your Location is On.
No brainer right? Turn your Location to Off if you don’t wanna be tracked. Mine is always off!
In the case of 1/6/2021 on the US Capitol:
Trump supporters traveled from South Carolina, Florida, Ohio and Kentucky to the nation’s capital, with pings tracing neatly along major highways, in the days before the attack. Stops at gas stations, restaurants and motels dot the route like bread crumbs, each offering corroborating details.
In many cases, these trails lead from the Capitol right back to their homes.
Times Opinion was able to identify individuals from a trove of leaked smartphone location data.
POWERPASTE, a high-density, safe, and easily transportable hydrogen energy fuel
The future for hydrogen fuel? 😃
Researchers have developed a magnesium-based POWERPASTE that stores hydrogen energy at 10 times the density of a lithium battery, ideal for small vehicles.
Motorcycle with the comfort of a car
😃 Very interesting motorcycle.
Freedom of classic motorcycles with the safety of cars.

Tesla Could Be One of First Automakers to Use UWB Technology in Its Vehicles
Tesla may be one of the first automakers to use Ultra-wideband (UWB) technology in their vehicles. According to documents filed with the Federal Communications Commission, the manufacturer has submitted new products that support UWB.
Supercomputers advance longer-lasting, faster-charging batteries
In an effort to curb the rise in overall carbon vehicle emissions, the state of California recently announced a plan to ban new sales of gasoline-powered vehicles in less than 15 years—if the current governor’s order holds strong.
Porsche is 3D printing electric drive housings that are lighter and stronger than conventional ones
In December, Porsche announced that it had been 3D printing prototype housings for electric drives that were stronger, lighter, and much quicker to manufacture. The engine-gearbox units produced using this method were even able to pass all of the company’s quality and stress tests without issue.
Porsche manufactures the housings using a 3D printing method called laser metal fusion, which entails a laser beam heating and melting a powder surface depending on the desired contours. This method allows Porsche to produce an engine gearbox that is both 10% lighter and 100% stronger because of the inherent lattice structures.
Another significant upside to manufacturing parts this way is the ease and speed of creating new components or making changes to existing ones. For example, an entirely new part can be designed and then physically printed very quickly with no need to do things such as create new tooling to manufacture the part.
Tesla’s Crazy Yoke Could Enable Flight Controls, Activate Rockets On Roadster
Elon Musk says the Tesla Roadster will be able to fly a little bit, so perhaps the new Model S yoke will be used so that the driver pulls back on it to fly.
Ingenious ‘Wrinkled’ Graphene Could Be The Most Promising Water Filter Yet
Graphene continues to dazzle us with its strength and its versatility – exciting new applications are being discovered for it all the time, and now scientists have found a way of manipulating the wonder material so that it can better filter impurities out of water.
The two-dimensional material comprised of carbon atoms has been studied as a way of cleaning up water before, but the new method could offer the most promising approach yet. It’s all down to the exploitation of what are known as van der Waals gaps: the tiny spaces that appear between 2D nanomaterials when they’re layered on top of each other.
These nanochannels can be used in a variety of ways, which scientists are now exploring, but the thinness of graphene causes a problem for filtration: liquid has to spend much of its time travelling along the horizontal plane, rather than the vertical one, which would be much quicker.
GM Pushes Ahead With Hydrogen Fuel Cell Technology For Long Haul Trucks
Hydrogen. In theory, it’s the perfect fuel. Run it through a fuel cell and you get electricity, water vapor, and heat. Doesn’t get any more Earth friendly than that, does it? There is theory and then there is reality, starting with where one gets the hydrogen in the first place. It is one of the most abundant elements on Earth — every molecule of water has two hydrogen atoms and there is a lot of water in the world.
Then there is the whole universe of hydrocarbons from gasoline to plastics. By definition, there are hydrogen atoms in all of them and that’s the problem. Hydrogen is so reactive it bonds with everything. Getting pure hydrogen means breaking the chemical bonds that bind to other elements. Keeping it sequestered in its pure state is a whole other conundrum.
Assuming all those challenges are overcome, then comes the question of how to distribute it so it can be used to power the fuel cells in vehicles. A DC fast charging installation might cost $300000 but a hydrogen refueling station can cost $3 million. Compressing it, trucking it, and storing it all present additional hurdles to consider.
