Nikola Motor Company Enters Electric Vehicle Market with 2,000hp Truck

As reported by Tech DailyA new electric vehicle company breaks cover led by Trevor Milton. The Nikola Motor Company has come out of hiding announced the Nikola One class 8 electric semi-Truck and the Nikola Zero 4×4 electric UTV.

The Salt Lake City based electric vehicle startup has been created by Trevor Milton, who has been CEO of dHybrid Systems, a natural gas storage technology company that got acquired by Worthington Industries in 2014.
The Nikola One Truck has 2,000 hp and a 1,200 miles range. It carries 320kWh battery that power the 6×6 electric drive. The Nikola One has regenerative braking and a turbine that charges the batteries.
The Nikola Zero UTV has a 100 to 150 miles range and 520hp. The all-wheel drive UTV has a 50kWh battery and accelerates to 60mph in 3s. The Nikola Motor Company takes a page out of Tesla Motors playbook and offers reservations of their vehicles which are in a prototype stage. The Nikola One Truck can be reserved for $1,500 and the UTV for $750.
There is no word yet on when Nikola Motor Company will be able to actually deliver any of their planned vehicles. Prototypes are supposed to be shown later this year. Nikola Motor Company is of course named after the famous inventor and electrical engineer Nikola Tesla. If the name brings good fortunes remains to be seen.
The Nikola Motor Company released many technical details about their planned electric vehicle that look impressive. At least we know what electric vehicle this company is working on, in contrast to secretive Apple, which is also supposed to build an electric vehicle under the project Titan.

Personal Aircraft Aiming to Take Off From Your Home

As reported by Phys.OrgA start-up company hosted in an ESA business incubator is developing the world's first vertical takeoff and landing aircraft for personal use. The electric two-seater will open the door to a new class of simpler, quieter and environmentally friendly planes available from 2018.

"Our goal is to develop an aircraft for use in everyday life," explains Daniel Wiegand, CEO and one of the company's four founders.
"We are going for a plane that can take off and land vertically and does not need the complex and expensive infrastructure of an airport.
"To reduce noise and pollution, we are using electric engines so it can also be used close to urban areas."
Founded in February 2015 by four engineers and doctoral students from the Technical University of Munich in Germany, Lilium has already proved the concept with several scale, 25 kg prototypes and is now developing its first ultralight  and landing aircraft.
Simpler and easier air transportation
Today, general public aviation offers fixed-wing aircraft and helicopters. Conventional aircraft are efficient, fast and available in many sizes but require airports often 20–50 km from city centres because of their space-hungry runways and the high noise levels.
Airports are expensive bottlenecks for transportation. This is especially so for short-haul flights, where travel time to and from airports can easily double the duration of a trip. This is not a problem for helicopters, which can take off almost anywhere and are therefore often used for short shuttle flights and special applications.

However, helicopters are very noisy and difficult to fly – which requires expensive licences. They also have no backup in case of rotor failure, making them expensive to build and maintain.
The Lilium vehicle combines the benefits of helicopters and fixed-wing aircraft while avoiding their drawbacks. While initially restricted to airfields, the goal is for it to take off vertically from almost anywhere – even from back gardens – it needs only an open flat area of about 15x15 m.
Although taking off and landing like a helicopter, by swivelling its engines it also functions as a very efficient aircraft that can travel at up to 400 km/h.

Entirely electric, the plane is much quieter during takeoff than helicopters thanks to its ducted fan engines. Its batteries, engines and controllers are redundant, making it a much safer design than conventional helicopters.
The plane is classed as a Light Sport Aircraft for two occupants, with the pilot's licence requiring 20 hours' minimum training – almost like taking a driving licence.
It is intended for recreational flying during daylight, in good weather conditions and in uncongested airspace up to 3 km altitude.

Using computer control for vertical takeoff and landing is essential for a vehicle targeted at the consumer market for personal transportation.
Powered from a simple wall plug
Highly efficient in its cruising mode, the vehicle will have a range of 500 km. It features a touchscreen and fly-by-wire joystick controls, retractable landing gear, wing doors, large storage, panoramic windows, and a battery that can be recharged from any wall plug.

Satnav is crucial to the high degree of automation and wind compensation during takeoff and landing.
The company is hosted at ESA's Business Incubation Centre in Bavaria, which offers a workshop for developing and building the prototypes and final plane.
Located directly next to the Special Airport Oberpfaffenhofen, the company has direct access to test fields and an inspiring aviation-friendly environment.

"The half-size prototype is already flying and now under test. The full-size unmanned prototype is planned for this summer," says Thorsten Rudolph, CEO of AZO, which runs the incubator, one of many in ESA's Technology Transfer Programme throughout Europe.
"We are helping the Lilium team to turn their idea into a viable business. They are the aircraft experts, and we provide the expertise on how to make a business out of their dream."
Supported by a venture capital investor, the company is planning its first manned experimental flight in 2017 and rollout of the completed vehicle for licensing by 2018, ready for initial production to begin meeting orders. Serial production will follow later.
The retail cost will be far less than similar-sized aircraft of today and with much lower running costs.
"In the longer term, our target is to build an  that not only the super-rich can afford, and that can make private air transportation possible for a much wider number of people," adds Daniel.
"With the concept of taking off and landing almost everywhere, we could see that one day our plane will be used for quick and daily transportation almost like a car today."

Tiny Optical Frequency Clock Measures Time Accurately to 270 Quintillionths of a Second

The optical clock developed by UCLA Engineering researchers is the small black strip between the two black cylinders.
As reported by Phys.OrgResearchers at the UCLA Henry Samueli School of Engineering and Applied Science have created an optical clock that's just 1 cubic centimeter—small enough to fit on a standard silicon chip—and can track time intervals with precision to 270 quintillionths of second. (One quintillionth is equivalent to 1 times 10 to the negative 18th power, or 0.000000000000000001.)

Today's most accurate clocks, atomic clocks, are used to keep time for the Internet and satellite communications, and help astronomers detect Earth-like planets beyond our solar system. Their accuracy—to "only" within a tenth of trillionths of a second, or 1 times 10 to the negative 13th power—is based on the naturally occurring frequencies of atoms that respond to radiation. The atomic frequencies can be expressed as a "frequency comb," a series of evenly spaced vertical lines of light produced by the atoms under radiation into microwave frequencies that are accessible to the electronic instruments that ultimately turn those readings into accurate measurements of time.
Previous optical clocks were much larger than the new one developed at UCLA: They used large fiber lasers that needed to be housed in equipment about the size of a desktop computer. The UCLA team was able to shrink the mechanism significantly to 1 cubic centimeter by using a process similar to how silicon chips are made. The new clock's precision approaches the world's best frequency standards.
The clock could lead to more precise measurements of space and time, an area known as attosecond physics, and could have applications in optical, wireless and space-based communications. For example, it could be used to measure the movement of atoms, or to discern the movement of distant objects far beyond our solar system.
"If incorporated with other technologies into infrared telescope observatories, this device can enable the detection of Earth-like planets and celestial objects 100 times smaller than that, which was previously impossible," said Shu-Wei Huang, a UCLA Engineering scientist and the project's lead author. The research was published in Science Advances. Chee Wei Wong, a UCLA associate professor of electrical engineering, is the project's principal investigator.
"Measuring the time it takes for a pulse of light to reflect from an object and return back to us also tells us a distance," Wong said. "This could help in precision laser distance ranging, such as in sensing for self-driven automobiles and aerial vehicles."
Wong said the laser clock could help generate ever-shorter pulses of light, which would be useful for watching the motion of electrons or detecting trace hazardous materials from faraway distances.
The new clock could also help further refine the absolute value of "fundamental constants," numbers that are thought to be same throughout the universe—for example, the strength of electromagnetic interactions between electrons and other elementary particles.
Wong said because the clock is cast on a silicon chip, it is more reliable than the previous, larger model, which required additional stabilization and control electronics to work.
The paper's other authors are Jinghui Yang of UCLA, Mingbin Yu and Dim-Lee Kwong of Singapore's Institute for Microelectronics , and Bart McGuyer and Tanya Zelevinsky of Columbia University.

SpaceX Has Landed its Fastest-Flying Rocket Yet on a Floating Platform at Sea

As reported by QuartzFlying satellites and landing rockets are almost becoming routine for the Elon Musk’s rocket company, but SpaceX still managed to wedge a new milestone into their latest flight.

After launching JCSAT-14, a Japanese satellite that will provide TV and data services across the Pacific early this morning, SpaceX landed the first stage of its rocket on a floating platform at sea for the second time ever, a novel technique the company has developed to reuse more of its rockets and save costs.

Today’s landing does offer something new to the discerning observer: This is the first time that the company has landed a rocket that flew to “geosynchronous transfer orbit,” or GTO. That means it set its satellite cargo on a path to reach an altitude where the speed of its orbit will match the speed of earth’s rotation, allowing it to “hang” over one place, about 36,000 kilometers above us.

To get that high, the rocket must be going much faster than to reach, say, the International Space Station in low earth orbit. You can get a sense of the distance with our satellite map. So far, SpaceX has only landed reusable rockets that had delivered payloads to low earth orbit, because they’re already going slower when it comes time for them to turn around and head for earth.
When the rocket is taking its cargo to GTO, it requires three times the deceleration of one heading for low earth orbit. When the company tried to land a rocket that sent cargo to GTO earlier this year, it landed “hard,” though no images were released—we imagine it looked something like this failed landing from January, 2015:

But, as always with Musk, there’s a business plan behind the technology. The most lucrative satellites are those that hang over one spot on earth in their geosynchronous orbits. Introducing reusability into that launch market is key to lowering the price and growing SpaceX’s market share. And, at a time when numerous companies are developing cheap solutions to launch satellites in to low-earth orbit, ensuring dominance at the highest of altitudes will insulate SpaceX from those competitors.

Besides rocket reusability—and its implications for a trip to Mars—the big 2016 goal for SpaceX is a steady launch tempo. Initially, the plan ran into trouble thanks to a new fueling system, but it appears the kinks have been sorted out. The company has so far launched four out of 18 launches expected by SpaceX president Gwynne Shotwell.

This is the third first stage that SpaceX has landed, leading Musk to joke that he’ll need a bigger rocket storage hangar. But that also raises the question: When will one of these rockets be re-used?

SpaceX Hired a Superhero Suit Designer to Create Its Upcoming Spacesuit

As reported by Popular Mechanics: Jose Fernandez is the founder and lead designer at Ironhead Studios, the company responsible for designing numerous superhero suits for the big screen. The studio has tackled Spiderman,Thor, and most recently, Batman. But the next big suit with Ironhead's touch sounds like it'll be for real-life spacemen. Namely, the ones that will work for our real-life Tony Stark, Elon Musk.

In an interview with Tested, Fernandez offhandedly mentioned his work for SpaceX. "I designed a spacesuit for SpaceX," Fernandez says, at the end of a clip highlighted by a Redditor on the subreddit devoted to the private spaceflight company. "I can't show [it], but they're gonna reveal it in the next possible year."


As another Redditor was quick to point out, this isn't the first time Frenandez mentioned the project, just the first time anyone really picked up on it. In an interview with BLEEP magazine earlier this year, Fernandez went into deeper detail about the project, perhaps most interestingly about how concerned Musk was with the suit's style, and how the suit was first designed to look awesome and then was (or is still in the process of being) reverse-engineered from there.

As Fernandez told BLEEP:
"I worked with [Musk] for six months and at the end of that, we created a suit that they are now reverse-engineering to make functional for flight. The look they are going to unveil in the next few months is something we created here in the studio. He wanted it to look stylish. It had to be practical but also needed to look great. It's pretty bad ass. He kept saying, "Anyone looks better in a tux, no matter what size or shape they are," and when people put this space suit on, he wants them to look better than they did without it, like a tux. You look heroic in it. It's an iconic thing be a part of."
It's a priority Musk has stressed before, and considering the sort of delightful but cartoonish look of NASA's upcoming suits, it seems like Musk should have plenty of room to edge in the SpaceX suit as "the cool one." Until the actual reveal, we'll just have to guess at how it might look, but lets just say the bar is looking pretty high.

SpaceX teased the new suit in a Crew Dragon conceptual video last year; though there's no guarantee that Frenandez's suit will look anything like what you've seen so far:

Whatever's happening, this won't be an easy task. Spacesuits have understandably stricter demands for comfort, durability and safety -- a ripped, damaged, or malfunctioning suit in space can do a lot more than ruin a day of filming.

Tesla Puts its Extreme Air Pollution Filter to the Test

As reported by Engadget: When Tesla revealed that the Model X (and eventually, the Model S) would have a HEPA filter so effective that it could protect against bioweapons, people were understandably skeptical. Can it really save you from terrorists? Apparently, it just might. Tesla has revealed some of the in-house testing it conducted for the filter's Bioweapon Defense Mode, and its ability to clean the air borders on overkill. 

The electric car maker put a Model X into a bubble with extremely dangerous air quality levels (83 times dirtier than the EPA's "good" rating) and watched as the filtration system rendered the air so clean that sensors couldn't even detect what pollution was left. You could drive through a "military grade" attack and not even notice, Tesla claims.

The company adds that its filter also reduces some of the pollution outside of the car, and that it's constantly tweaking the filter technology. Replace your filters down the line and your EV might be even more of a clean room than it was brand new.

It's impressive stuff, although the test is more about bragging than real-world practicality (which Tesla also checked, to be fair). You don't need a near-sterile car even in pollution-heavy cities like Beijing, and the odds are that you aren't going to be in your vehicle should someone ever unleash a bioweapon on your home turf. Think of this more as proof that Tesla's over-the-top engineering really works... most of the time, anyway.

Google's Self-Driving Tech May Go Into Chrysler Minivans This Year

As reported by Engadget: That rumored deal between Google and Fiat Chrysler for self-driving car technology? It's reportedly happening... if not quite in the way you'd expect. Bloomberg sources claim that the arrangement will put some of Google's autonomous tech into the 2017 Chrysler Pacifica minivan sometime this year. Just how deep this integration would go isn't clear, but it's not believed to be an exclusive arrangement -- either side could cooperate with other partners. If the leak is accurate, the deal could be signed as soon as May 3rd (if you're reading this in time, today).

Once again, the partnership makes more sense than you might think. Google (or rather, Alphabet) already said that it wasn't going to mass-produce its own cars, so it was always going to need help -- this is its first major deal. Fiat Chrysler, meanwhile, has been hoping for a fast track to self-driving technology to help it compete against rivals that have already done a lot of legwork.

And minivans? They could make more sense than you think. While you're unlikely to see truly driverless Chryslers anytime soon, this would show that Google's know-how can improve one of the most mainstream vehicles you can find: a run-of-the-mill (if relatively high-end) family carrier. If Google and Fiat Chrysler succeed there, the technology could easily spread to other models and manufacturers.
