For $200,000, Tesla Will Sell You The 'World's Fastest' Consumer Car

Nov 18: Tesla's very first car is back. It's red. It's fast. And it will cost you upward of $200,000.

The Roadster, the electric sports car that put the automaker on the map, made a surprising appearance at Tesla's semi-truck event late Thursday. The next-generation Roadster is Tesla's first new sports car since it discontinued the original in 2012, and marks the company's bid to remain competitive across several categories in the world of electric vehicles that it helped reshape.

The updated Roadster will achieve world record speeds, Tesla chief executive Elon Musk said during the event in Los Angeles. The base model can travel from a dead stop to 60 miles per hour in less than two seconds, making it the fastest consumer car on the planet, and the first to break the two-second mark, Musk said. He declined to give the Roadster's top speed but said it would surpass 250 mph.

But while Musk and his audience were characteristically gleeful, investors and some auto analysts were skeptical about the company's prospects. Tesla's stock fell nearly four percent in midday trading Friday. Some industry observers pointed to the company's production delays in its mass-market Model 3. Ed Hellwig, a senior editor at auto research website Edmunds.com, described the Roadster as a "very unnecessary distraction" whose reintroduction was likely designed to divert attention from Tesla's business struggles.

The company reported a net loss of $619 million, or about $2.92 per share,in its most recent earnings report, compared with a net income of $21 million and a gain of 71 cents per share, during the same period last year. Tesla also said recently that it had fired hundreds of employees after annual performance reviews. And it's unclear, even as the company faces production bottlenecks, where the new Roadster will be manufactured.

Analysts said that it's too early to tell if the Roadster will help lift Tesla to profitability, but the sports car gives the company's image a boost. "You can say a lot of things about Tesla, but one thing it's done is built a brilliant brand," said Michelle Krebs, executive analyst at Autotrader.

The original Roadster, released nearly a decade ago, was Tesla's the first step in a multistage process to entice the public with its promising technology and eventually offer all-electric vehicles to the masses. The company showed that electric vehicles could preform just as well, and perhaps even better, than cars powered by fossil fuel. Its limited run, in Tesla's view, was part of the plan.

"We started Tesla with a sports car, the Tesla Roadster. That baby got us going. It was the foundation of the whole company," said Musk said. "People have asked us for a long time, 'When are you going to make a new roadster?' We are making it now."

The successor, like the original, was designed to make a splash. The unveiling itself was a surprise, coming after Musk showed off Tesla's long-anticipated semitruck. But beyond Musk's flair for showmanship, experts said the new Roadster gives Tesla a prestige product to showcase and compete with.

"It's got a lot of sizzle. It worked before, and why not," said Krebs. "If they get it on the roads it will be something that will go head-to-head with Porsches and Ferraris and all the exotic vehicles."

Toni Sacconaghi, an analyst at Bernstein Research, described the Roadster as a "brand enhancing," car, in a note to investors Friday. But he also said he sees it as a low-volume product. He cautioned that Tesla should focus on building and selling the economy-class Model 3, rather than broadening its initiatives with new vehicles and energy projects.

While experts did not go so far as to describe the Roadster as a game changer, they said it will allow Tesla to challenge automakers of high-end sports cars who have been nudged, largely by Tesla, to make high-powered electric vehicles of their own. Musk made that argument in more colorful language. "The point of doing this is to just give a hardcore smackdown to gasoline cars," he said. "Driving a gasoline sports car is going to feel like a steam engine with a side of quiche."

Tesla says the car will come with a 200-kilowatt-hour battery, giving it a range of 620 miles at highway speeds without the need to recharge. In comparison, the current 75-kilowatt-hour battery in the Model S gives the sedan a 250-mile range. To put the Roadster's battery endurance into perspective, Musk said a driver would be able to travel from Los Angeles to San Francisco, and back again, on a single charge.

Up to four people can fit in the Roadster with "plenty of storage," Musk said. But he was quick to add that you can't put "giant" people in the back seat. The car will feature all-wheel drive and will have three motors.

The first customers of the new Roadster will have to wait a few years before they can climb in and let the top down, however. Musk said the car will not be available until 2020. The "Founders Series" will go for $250,000, but its specifications won't be shared until as early as next year, Musk said.

Leiden, Jul 2: Astronomers have discovered a luminous galaxy caught in the act of reionizing its surrounding gas only 800 million years after the Big Bang.

The research, led by Romain Meyer, PhD student at UCL in London, UK, has been presented at the virtual annual meeting of the European Astronomical Society (EAS).

Studying the first galaxies that formed 13 billion years ago is essential to understanding our cosmic origins. One of the current hot topics in extragalactic astronomy is 'cosmic reionization,' the process in which the intergalactic gas was ionized (atoms stripped of their electrons).

Cosmic reionization is similar to an unsolved murder: We have clear evidence for it, but who did it, how and when? We now have strong evidence that hydrogen reionization was completed about 13 billion years ago, in the first billion years of the universe, with bubbles of ionized gas slowly growing and overlapping.

The objects capable of creating such ionized hydrogen bubbles have however remained mysterious until now: the discovery of a luminous galaxy in which 60-100 percent of ionizing photons escape, is likely responsible for ionizing its local bubble. This suggests the case is closer to being solved.

The two main suspects for cosmic reionization are usually 1) a population of numerous faint galaxies leaking ~10 percent of their energetic photons, and 2) an 'oligarchy' of luminous galaxies with a much larger percentage (>50 percent) of photons escaping each galaxy.

In either case, these first galaxies were very different from those today: galaxies in the local universe are very inefficient leakers, with only <2-3 percent of ionizing photons escaping their host. To understand which galaxies governed cosmic reionization, astronomers must measure the so-called escape fractions of galaxies in the reionization era.

The detection of light from excited hydrogen atoms (the so-called Lyman-alpha line) can be used to infer the fraction of escaping photons. On the one hand, such detections are rare because reionization-era galaxies are surrounded by neutral gas which absorbs that signature hydrogen emission.

On the other hand, if this hydrogen signal is detected it represents a 'smoking gun' for a large ionized bubble, meaning we have caught a galaxy reionizing its surroundings. The size of the bubble and the galaxy's luminosity determines whether it is solely responsible for creating this ionized bubble or if unseen accomplices are necessary.

The discovery of a luminous galaxy 800 million years after the Big Bang supports the scenario where an 'oligarchy' of bright leakers emits most of the ionizing photons.

"It is the first time we can point to an object responsible for creating an ionized bubble, without the need for a contribution from unseen galaxies.

Additional observations with the upcoming James Webb Space Telescope will enable us to study further what is likely one of the best suspects for the unsolved case of cosmic reionization," said Meyer.

Bengaluru, Jun 30: Karnataka Chief Minister BS Yediyurappa on Monday launched 'Skill Connect Forum' and said that the government is committed to provide impetuous to creating jobs by reviving economic and industrial activities.

The 'Skill Connect Forum' portal connects both private entrepreneurs and job seekers on the same platform.

After launching the forum, the Chief Minister said that the portal provides information on jobs available and who needs a job. "Under this forum, an unemployed will be imparted skills and then enabled to get a job," Yediyurappa said.
Besides providing jobs via registration, the portal also provides a skilled pool of people for those looking to hire, he added.

Deputy Chief Minister Dr CN Ashwath Narayan, who is also the Skill Development Minister said that portal will be a boon to the youth seeking jobs and it will avoid unemployment issue to a great extent.

"All these years, there was no information and communication between job seekers and recruiters. The portal will solve that problem," he said.

Narayan said that there was no proper information on skilled workers and job market. Moreover, skill development was not in sync with the market. All these issues have been addressed by the portal, he added.

In a study conducted in 117 countries, researchers have found that the world is experiencing the most dramatic reduction in the seismic noise (the hum of vibrations in the planet's crust) in recorded history due to global COVID-19 lockdowns.

Measured by instruments called seismometers, seismic noise is caused by vibrations within the Earth, which travel like waves and the waves can be triggered by earthquakes, volcanoes, and bombs - but also by daily human activity like travel and industry.

This quiet period was likely caused by the total global effect of social distancing measures, closure of services and industry, and drops in tourism and travel, the study published in the journal Science, reported.

The new research, led by the Royal Observatory of Belgium and five other institutions around the world including Imperial College London (ICL), showed that the dampening of 'seismic noise' caused by humans was more pronounced in more densely populated areas.

"Our study uniquely highlights just how much human activities impact the solid Earth, and could let us see more clearly than ever what differentiates human and natural noise," said study co-author Stephen Hicks from ICL in the UK.

For the findings, the research team looked at seismic data from a global network of 268 seismic stations in 117 countries and found significant noise reductions compared to before any lockdown at 185 of those stations.

Researchers tracked the 'wave' of quietening between March and May as worldwide lockdown measures took hold.

The largest drops in vibrations were seen in the most densely populated areas, like Singapore and New York City, but drops were also seen in remote areas like Germany's the Black Forest and Rundu in Namibia.

Citizen-owned seismometers, which tend to measure more localised noise, noted large drops around universities and schools around Cornwall, UK and Boston, US - a drop in noise 20 per cent larger than seen during school holidays.

The findings showed that countries like Barbados, where lockdown coincided with the tourist season, saw a 50 per cent decrease in noise.

"The changes have also given us the opportunity to listen in to the Earth's natural vibrations without the distortions of human input," the study authors wrote.

Earlier in April, a study published in the journal Nature, reported at least a 30 per cent reduction in that amount of ambient human noise since lockdown began in Belgium.
