Made in America: The world's fastest electric car

Some of you who've been with us from the beginning might recall Mangesh's post a couple years back about Tesla's high-end electric sports car, made in Silicon Valley. In the post, Mango wrote mental_floss' favorite inventor Nikola Tesla, who famously dreamed up AC current amongst a million other things, and inspired the names for the rock bands Tesla and AC/DC (or at least the first-half of the name AC/DC), now has a ridiculously cool electric car named for him"¦[Tesla] even plans on releasing a family sedan by 2008.

And while the sedan is still a couple years off, the Roadster, which Mangesh referred to, is not only selling pretty well (for a vehicle with a base sticker price that's more than $100K), but showrooms are slowly starting to open outside Silicon Valley. One opened in L.A. not too long ago and I had the privilege of interviewing the guy who runs it, Jeremy Snyder. So if you're into really fast cars, really expensive cars, or just environmentally friendly cars, read on for the lowdown on Tesla, right from the manager's mouth.

DI: So where exactly is Tesla based?

JS: San Carlos, California, though the cars are assembled in Menlo Park.

DI: The parts are made here too?

JS: The final assembly is here in California. We're an American car company. While the parts are from all over the world, the battery pack, which is a big part of the car, is made here in California.

DI: And how many different models are there at the moment?

JS: Just the Roadster right now, which is our flagship model. But we've got a four-door, five-passenger sedan coming out called Model S, which will be available in a couple years.

DI: So let's talk about the Roadster. What's all the hubbub?

JS: It's a very important car because it's 100% electric. We wanted to enter the market place and shatter any preconceived notions. Efficiency and performance need not be mutually exclusive. The car was designed with three principles in mind: Great design, ultra-high performance, while being the most efficient car in the world. It does 0-60 in 3.9 seconds, has a range of 244 miles per charge, charges in 3-4 hours, and costs about two cents per mile to operate.

DI: Fantastic. And all that will cost us how much?

JS: $109,000 base price, fully loaded is about $125K.

DI: What kind of extras are we talking about?

JS: Premium leather interior, carbon-fiber hard top, and a high-powered connector, which is installed in your home, which allows you to charge in 3-4 hours.

DI: How would people charge it otherwise?

JS: There's an extension cord that you can plug into any standard 110 outlet.

DI: How long does it take to charge with the cord?

JS: At half-charge, it will take overnight to recharge. If you're totally empty, it could take a lot longer than that.

DI: So how many of these babies have you sold to date?

JS: More than 1,300.

DI: Let's talk about the motor. Is it as silent as my little hybrid when I cruise to a stop?

JS: Well the electric motor is a helluva lot bigger than in a Prius, so you hear a very pleasant turbine-type sound when you're accelerating hard. But when you're accelerating at a slow pace, it's completely silent.

DI: Who's the engineer behind it?

JS: J.B. Strobel. He's our chief technology officer. He invented the battery pack, which is liquid-cooled, which allows the car to exist as it does. The power-electronics, the battery technology and the motor work in harmony, and that's what gives the car it's high-performance and range.

DI: What do you drive?

JS: A Tesla.

DI: Really? To and from work?

JS: Yeah. Either my Tesla or my bicycle.

DI: Do you get a lot of people stopping you in supermarket parking lots with questions?

JS: Of course. Yeah.

DI: You must be sick of that by now.

JS: Not at all. It's a very special car, and a very important one.

DI: Let's talk about maintenance. What are we talking?

JS: Well, there are no oil changes because there's no oil in the car. So it's essentially firmware updates, suspension, brakes, tires, the cooling system that cools the batteries, which is very important and that's about it. All in all it's about a six-hour service. We're opening service centers in New York City, Miami, Chicago, D.C., and Seattle over the next 12 months. It's only a once-a-year maintenance program, but this way they won't have to ship the car back to us here.

An Eco-Friendly Startup Is Converting Banana Peels Into Fabric for Clothes

A new startup has found a unique way to tackle pollution while simultaneously supporting sustainable fashion. Circular Systems, a “clean-tech new materials company,” is transforming banana byproducts, pineapple leaves, sugarcane bark, and flax and hemp stalk into natural fabrics, according to Fast Company.

These five crops alone meet more than twice the global demand for fibers, and the conversion process provides farmers with an additional revenue stream, according to the company’s website. Fashion brands like H&M and Levi’s are already in talks with Circular Systems to incorporate some of these sustainable fibers into their clothes.

Additionally, Circular Systems recycles used clothing to make new fibers, and another technology called Orbital spins those textile scraps and crop byproducts together to create a durable type of yarn.

People eat about 100 billion bananas per year globally, resulting in 270 million tons of discarded peels. (Americans alone consume 3.2 billion pounds of bananas annually.) Although peels are biodegradable, they emit methane—a greenhouse gas—during decomposition. Crop burning, on the other hand, is even worse because it causes significant air pollution.

As Fast Company points out, using leaves and bark to create clothing may seem pretty groundbreaking, but 97 percent of the fibers used in clothes in 1960 were natural. Today, that figure is only 35 percent.

However, Circular Systems has joined a growing number of fashion brands and textile companies that are seeking out sustainable alternatives. Gucci has started incorporating a biodegradable material into some of its sunglasses, Bolt Threads invented a material made from mushroom filaments, and pineapple “leather” has been around for a couple of years now.

Undersea Internet Cables Could Be Key to the Future of Earthquake Detection

Considering that 70 percent of the planet is covered by oceans, we don't have all that many underwater earthquake sensors. Though there's plenty of seismic activity that happens out in the middle of the ocean, most detection equipment is located on land, with the exception of a few offshore sensor projects in Japan, the U.S., and Canada.

To get better earthquake data for tremors and quakes that happen far from existing sensors, a group of scientists in the UK, Italy, and Malta suggest turning to the internet. As Science News reports, the fiber-optic cables already laid down to carry communication between continents could be repurposed as seismic sensors with the help of lasers.

The new study, detailed in a recent issue of Science, proposes beaming a laser into one end of the optical fiber, then measuring how that light changes. When the cable is disturbed by seismic shaking, the light will change.

This method, which the researchers tested during earthquakes in Italy, New Zealand, Japan, and Mexico, would allow scientists to use data from multiple undersea cables to both detect and measure earthquake activity, including pinpointing the epicenter and estimating the magnitude. They were able to sense quakes in New Zealand and Japan from a land-based fiber-optic cable in England, and measure an earthquake in the Malta Sea from an undersea cable running between Malta and Sicily that was located more than 50 miles away from the epicenter.

Seismic sensors installed on the sea floor are expensive, but they can save lives: During the deadly Japanese earthquake in 2011, the country's extensive early-warning system, including underwater sensors, was able to alert people in Tokyo of the quake 90 seconds before the shaking started.

Using existing cable links that run across the ocean floor would allow scientists to collect data on earthquakes that start in the middle of the ocean that are too weak to register on land-based seismic sensors. The fact that hundreds of thousands of miles of these cables already crisscross the globe makes this method far, far cheaper to implement than installing brand-new seismic sensors at the bottom of the ocean, giving scientists potential access to data on earthquake activity throughout the world, rather than only from the select places that already have offshore sensors installed.

The researchers haven't yet studied how the laser method works on the long fiber-optic cables that run between continents, so it's not ready for the big leagues yet. But eventually, it could help bolster tsunami detection, monitor earthquakes in remote areas like the Arctic, and more.
