Barely a decade ago, Mate Rimac was toiling in an unheated garage in Croatia, converting an old BMW to run on electricity for drag-racing competitions.

Today, the 33-year-old entrepreneur has 900 employees, a headquarters near Zagreb, development deals with Porsche and Hyundai, and a factory about to produce the Rimac C Two, a €2 million, 1,427-kilowatt, 415-kilometer-per-hour electric phantasm. Its projected 1.85-second rip from 0 to 60 miles per hour (97 kilometers per hour) would make it the first production car to break the 2.0-second barrier.

Delayed for a year by the COVID pandemic, Rimac plans to bring the first 150 C Twos to market this year. The model is the follow-up to his notorious Concept One, a hypercar with a mere 913 kW (yes, that's 1,224 horsepower). But to Rimac, the tech is just a means to an end. The point is to win over EV skeptics and bring carbon-neutral mobility.

“Before Tesla, people were building ugly, boxy electric cars, telling a story of saving fuel," Rimac says in an interview. “That's relevant, but it only brings in a small percentage of people."

Base price:

US $2.4 Million

His company's multifarious projects include Greyp, the electric bicycle company; an EV he's developing for Hyundai's new N Line; batteries for Aston Martin and Jaguar; and technical projects with Porsche, which increased its Rimac stake to 15.5 percent in 2020.

“When Porsche invested, after three years of due diligence, that was like, another level for us," Rimac says. “Porsche is all-in on electric cars."

What have these guys got that Porsche hasn't got? Small size and vertical integration. They let the company focus on high-performance battery, power train, and vehicle design more quickly than can, say, the sprawling Volkswagen Group (Porsche's parent), whose annual revenues are more than four times the annual gross domestic product of Croatia.

Rimac's C Two integrates a 120-kilowatt-hour lithium-nickel-manganese-cobalt-oxide battery into an ultralight carbon-fiber frame, to deliver a nominal range of 550 kilometers (342 miles), as measured by Europe's regulatory protocol. Electric motors at each wheel allow true torque vectoring: Wheels can be individually powered or braked, delivering otherworldly handling. Rimac says the system allows near-instant calibrations of dynamic torque.

That wingman philosophy extends to the Rimac's autonomous Driver Coach, a kind of hyperdriving onboard HAL 9000 based on a GPS database from racetracks all over the world. The scissor-doored Rimac incorporates six driver screens, a lidar unit, 13 onboard cameras, 12 ultrasonic sensors, and an exceptionally precise localization system using multiple stereo cameras and inertial-measurement-unit sensors.

“We're trying to use autonomous tech to add value to enthusiasts," he says. “This system will give you autonomous laps to show how a professional driver would do it. Then you take over, and the system gives you onboard coaching, showing where to brake, where to turn in, what you did wrong, and what you can do better."

Rimac slyly notes that Nikola Tesla was born in Croatia and says that, as a young petrolhead, he was fascinated by the inventor and the possibilities of his “electric machines." Perhaps future entrepreneurs will remember Rimac as fondly as he remembers his hero.

TSMC to Build Chip Fab in Japan

Japanese government helps subsidize project as chip shortage threatens economies around the world

After a week of media rumor, leaks and speculation, Taiwan Semiconductor Manufacturing Co. (TSMC), the world's largest contract chip manufacturer, announced in an online earnings briefing Thursday that it would build a semiconductor plant in Japan. The announcement comes just a few months after the chip giant announced its intention to build a $12 billion fab in Arizona. Construction will begin next year, the company said, subject to approval by TSMC's board, with full production expected to begin in 2024.

"The plant will use 22- and 28-nanometer line processing," said Tadahiro Kuroda, Director of Systems Design Lab (d.lab) at the Graduate School of Engineering, the University of Tokyo. "So it's not an advanced foundry like the Arizona plant that will use 7 nanometers." But he adds it can produce a range of devices that go into consumer products, sensors, IoT, and auto parts.

EP29LPSP: Applications in Plasma Physics, Astronomy, and Highway Engineering

Ideal for demanding cryogenic environments, two-part EP29LPSP can withstand temperatures as low as 4K

3 min read

Since its introduction in 1978, Master Bond EP29LPSP has been the epoxy compound of choice in a variety of challenging applications. Ideal for demanding cryogenic environments, two-part EP29LPSP can withstand temperatures as low as 4K and can resist cryogenic shock when, for instance, it is cooled from room temperature to cryogenic temperatures within a 5-10 minute window. Optically clear EP29LPSP has superior physical strength, electrical insulation, and chemical resistance properties. It also meets NASA low outgassing requirements and exhibits a low exotherm during cure. This low viscosity compound is easy to apply and bonds well to metals, glass, ceramics, and many different plastics. Curable at room temperature, EP29LPSP attains its best results when cured at 130-165°F for 6-8 hours.

In over a dozen published research articles, patents, and manufacturers' specifications, scientists and engineers have identified EP29LPSP for use in their applications due to its unparalleled performance in one or more areas. Table 1 highlights several commercial and research applications that use Master Bond EP29LPSP. Table 2 summarizes several patents that reference EP29LPSP. Following each table are brief descriptions of the role Master Bond EP29LPSP plays in each application or invention.
