Sweeney responded: “Sounds doable, account and all my help. Any chance to up that to $50K?”
The 19-year-old cited college funding and told the billionaire the money could go towards buying a Tesla Model 3.
“I’ve done a lot of work on this and 5k is not enough,” Sweeney said in an interview with Insider. He added $5,000 wasn’t enough to replace “the fun I have in this, working on it.”
For the first time, scientists were able to create ultrashort dark and bright light pulses that are linked together in tiny glass rings called microresonators. Each of the flashes consist of many different, precisely defined colors: a frequency comb. The combination of the pulses increases the color range of the emitted light from the microresonators. This new light source helps to make more precise sensors to trace for example lowest quantities of explosives at an airport or for distance sensors in autonomous cars to detect obstacles on a street.
It sounds like magic: Laser light of only one color produce a rainbow of many different colors. Scientists are able to produce this strange effect in microresonators, small disks made of glass. If they send a pulsed laser beam into these structures, ultrashort packets of light waves are running in its interior in circles. And start to send out light of different, evenly spaced frequencies like the teeth of a comb. The invention of the optical frequency comb was awarded with the Nobel Prize in Physics in 2005.
Now, researcher from the Max-Planck-Institute for the Science of Light (MPL) in Erlangen and the Imperial College London were able to produce for the first time an even stranger effect: By directing two Laser beams of slightly different infrared light at the outer rim of the microresonator they got two wave packets, called solitons: one bright and one dark, which run in circles. A dark pulse means having a constant light signal that goes dark for a very short time. Both dark and bright light pulses only last for 1/1013 th of a second.
Boom expects to break ground this year on a 400,000-sq-ft Overture production plant and begin manufacturing of the supersonic airliner in 2024.
Energy company Royal Dutch Shell has started operations at the power-to-hydrogen electrolyzer in Zhangjiakou, China, a joint venture between Shell (China) and Zhangjiakou City Transport Construction Investment Holding Group, the Anglo-Dutch company wrote on Friday. The electrolyzer will reportedly provide about half of the total green hydrogen supply for fuel cell vehicles at the Zhangjiakou competition zone during this year’s Winter Olympic Games, set to begin on February 4. Shell looks set to make further investments in China’s hydrogen sector. “We see opportunities across the hydrogen supply chain in China, including its production, storage and shipping. We want to be the trusted partner for our customers from different sectors as we help them decarbonise in China,” commented Wael Sawan, director of Shell’s Integrated Gas, Renewable and Energy Solutions unit. The companies, which took 13 months to complete the project, have plans to scale the power-to-hydrogen electrolyzer up to 60 MW in the next two years. Utilizing onshore wind power, the project will initially supply green hydrogen to fuel a fleet of more than 600 fuel cell vehicles at the Zhangjiakou competition zone during the Winter Olympic Games. After that, the hydrogen will be used for public and commercial transport in the Beijing-Tianjin-Hebei region.
Green Hydrogen Systems, a provider of pressurized alkaline electrolyzers used in on-site hydrogen production based on renewable electricity, has signed a supply agreement with Edinburgh-based Logan Energy to deliver electrolysis equipment for a project in England. The order includes the supply of two electrolyzers with a combined capacity of 0.9 MW for the production of green hydrogen from renewable energy. “Manufactured by Green Hydrogen Systems and operated by Logan Energy, the electrolysers will be deployed in a 40 ft container as a complete green hydrogen plant as part of plans to develop a regional hydrogen economy in Dorset, England,” Green Hydrogen Systems wrote on Tuesday. When fully operational during Q4 of 2022, the ordered electrolyzers will reportedly have the capacity to provide approximately 389 kg green hydrogen per day.
Second, we need to be aware of the manifest biases and fallacies that magnify the weight humans put on potential losses compared to potential future gains. As a result of these biases, humans often seek to preserve the status quo over pursuing activities that lead to future changes, even when the expected (but risky) gains from the latter may outweigh those of maintaining the status quo. The preference for the status quo, and neat narratives that oversimplify complex scenarios, can lead to overlooking (or ignoring) important information that is not consistent with the current generally accepted meme — illustrated, perhaps, in Musk’s continued optimism for autonomous vehicles despite the evidence leading to others downscaling their forecasts.
The first and second points together lead to the third important consideration: the importance of independently verified data over forecasts and opinion in determining the need for and appropriateness of policy interventions. And data is historical by nature. Pausing to collect it rather than rushing to respond is recommended.
To that end, we can use available data to analyze whether increasing use of AI is demonstrably affecting key labor market performance indicators: labor productivity and multifactor productivity growth. If, as Keynes suggests, AI-driven technological change is increasing the potential for new means of economizing the use of labor to outrun the pace of finding new ways to use it, we would expect to see both statistics rising in the era dominated by AI. Yet as Figures 1 and 2 show, the exact opposite appears true for a wide range of OECD countries. Neither does the data suggest that other key labor market indicators have changed negatively with the advent of AI. As with the computer industry, we see the effects of AI everywhere but in the productivity statistics.
The goal of DARPA’s Robotic Autonomy in Complex Environments with Resiliency (RACER) program is to develop and demo new autonomy tech that enables ground combat vehicles to maneuver in unstructured, off-road terrain at speeds that are no longer limited by the autonomy software or processing time.
The company sold roughly one million cars in 2021.
The electric vehicle manufacturer announced yesterday that it made $5.5 billion in profits last year after selling nearly one million cars. That’s six times more than it did in 2020. But even those numbers weren’t enough to reassure investors that Tesla’s future success is a sure thing.
Surprisinglyfell sharply after the announcement because it also disclosed that supply chain problems have been forcing Tesla factories to run below capacity for months. Its 2022 outlook was also short on details about when new factories will come online, according to several analysts. Meanwhile, rival EV manufacturers are on the rise as the might of U.S. and global auto manufacturing shifts momentum into sustainable, electric vehicles.
The Concorde’s successor might be quieter.
NASA has completed the first test of the works on lowering the volume of supersonic flights in an effort to lift the ban on commercial supersonic flights, NASA’s Glenn Research Center announced.
The sonic booms happen when the merge of shock waves, created by breaking the sound barrier at the speed of 767 mph (1,235 kph). The huge amount of sound energy, approximately 110 decibels, generated by sonic booms sounds like thunderclaps or explosions and can be heard from 30 miles (48 km) away, which is why supersonic commercial flights are banned by the Federal Aviation Administration (FAA). physicists confirm that they have achieved a stage in nuclear fusion called “burning plasma”.
Tesla released an update regarding the Tesla Giga Berlin-Brandenburg plant in Grünheide near Berlin, Germany.
