Tesla’s next car will be a lot cheaper than expected
Tesla’s next car will be a lot cheaper than previously expected.
In fact, it could cost as little as $25,000.
CEO Elon Musk confirmed last year that its first mass market car, the Model 3, would price at about $35,000.
Autonomous Cars: Here’s a Look at Some of the Top Models
Autonomous cars have finally arrived, and they’re pretty remarkable. Here’s a look at the best on the line.
New algorithm improves speed and accuracy of pedestrian detection
What if computers could recognize objects as well as the human brain could? Electrical engineers at the University of California, San Diego have taken an important step toward that goal by developing a pedestrian detection system that performs in near real-time (2−4 frames per second) and with higher accuracy (close to half the error) compared to existing systems. The technology, which incorporates deep learning models, could be used in “smart” vehicles, robotics and image and video search systems.
Quantum Levitation
Researchers at the school of physics and astronomy at Tel Aviv University have created a track around which a superconductor (a material that is extremely efficient at transmitting electricity) can float, thanks to the phenomenon of “quantum levitation “.
This levitation effect is explained by the Meissner effect, which describes how, when a material makes the transition from its normal to its superconducting state, it actively excludes magnetic fields from its interior, leaving only a thin layer on its surface.
When a material is in its superconducting state — which involves very low temperatures — it is strongly diamagnetic. This means that when a magnetic field is externally applied, it will create an equally opposing magnetic field, locking it in place.
A material called yttrium barium copper oxide can be turned into a superconductor by exposure to liquid nitrogen — which makes it one of the highest-temperature superconductors.
Levitation isn’t just for Houdini anymore. Could this cool new tech lead to floating alternatives to traditional gas powered vehicles? Interesting times ahead!
Tesla’s falling out of favor
Not good. 2 weeks ago I mentioned concerns about the competitor enticing some of Tesla’s engineering talent.
There’s increased competition in the electric car space.
Physicists Figure Out A New Property Of Superconductivity
The finding could help scientists achieve reliable room-temperature superconductivity, which would help pave the way for innovations like levitating trains.
This futuristic fighter jet will probably be unveiled to America during the Super Bowl
A thing of beauty!
They zip and dart across the sky in a three-jet formation, a six-second apparition in a 30-second commercial touting the achievements of defense contractor Northrop Grumman. Unlike modern jets, such as the F-22 Raptor or F-16 Fighting Falcon, they have no tail and are likely to be armed with lasers that are straight out of a science-fiction movie.
They’re sixth-generation fighters, and Northrop Grumman appears poised to show them off during Super Bowl Sunday. The defense titan released a new commercial online Friday that touts its achievements and includes a glitzy glimpse at a plane whose fielding is likely decades away.
Here’s the clip in question:
