Three Modes in Three Days

There is no better way to start an argument here at Autopia then to start comparing the benefits and drawbacks of mass transit, bike commuting and driving to work. Everyone has an opinion and is utterly convinced it is right.

It got me thinking about my own commute here in Pittsburgh, Pennsylvania, so I decided to conduct an experiment: try each mode of transportation to see which was fastest. While I was at it, I decided to look at the overall cost and the health benefits as well.

With that in mind I set out on my adventure in commuting.

A Motorcycle Inspired By Pompeii and Decay

A lot of custom motorcycles look alike. The details and paint jobs may differ, but the general aesthetic rarely does. There are some builders who defy this, like Shinya Kimura, and their work always prompts a debate over what is, and isn’t, a motorcycle.

Now along comes Mark Dugally with Project Somma 2010, a bike that completely redefines the term.

The Southern California artist is a motorcyclist from way back, and this is the third custom he’s built. The others were more mainstream, if a cool replica of a Whizzer can be called mainstream. Not so with this machine, which was once an Aprilia Futura.

“I wanted to totally change the ergonomics and stale configuration of what we all recognize as a ‘bike,’” Dugally says.

Mission accomplished.

Tesla: Report Of Our ZEV Credits Was Greatly Exaggerated

Editors note: Tesla contacted us to contest an article analyzing the potential impact of zero emission vehicle (ZEV) tax credits on the company’s financial health. Although the company did not point out any errors requiring correction — and we stand behind the original article fully — we have provided Tesla with the opportunity to address certain points raised by our author.

We appreciate the opportunity to comment on the recent piece by Darryl Siry on the impact of zero emission vehicle (ZEV) credits to Tesla’s business.

Government programs such as California’s Zero Emissions Vehicle Program and others under consideration around the world support Tesla’s goal of accelerating the transition to electric vehicles. As disclosed in Tesla’s S-1 registration filed before our Initial Public Offering, ZEV credits supplemented the launch of the Roadster in June 2008.

In his piece, Siry credits a Tesla Finance Vice President with telling “analysts they could assume every Tesla Model S sold would generate approximately $5,000 in ZEV credit profit.” Based on that incorrect quote, he calculates that “$5,000 of pure profit per car represents a full 26 percent of the projected gross margins on the Model S and more than 50 percent of the projected bottom line.” Siry uses this analysis to imply that Tesla is dependent on the revenue from such credits and the absence of revenue to Tesla from their sale “may be the biggest threat to the viability of the Model S.”

We believe that such conclusions are incorrect as they are built on incomplete facts and an incorrect quote. As a public company our policy is to limit our forward looking statements, so we can’t comment on the specifics of future revenues. However, we can offer some facts to help the reader reach a balanced conclusion on the role of ZEV credits in Tesla’s future.

First, Tesla is not dependent on ZEV credit income. Siry noted that in our S-1 filing with the Securities and Exchange Commission that we generated $8.2 million from sales of ZEV credits, and that they accounted for 85% of our gross margin. However, he conveniently ignored the fact that this was related to 2009 financials. Our European sales had just begun in the second half of the year and we were in the early stages of Roadster production. Siry omitted to pull information from the same table that shows that in the most recent publicly filed quarter, we generated only $0.5 million of ZEV credit income—which represented a mere 13% of our gross margin. We think many readers might have drawn a different conclusion about our dependence had both facts been presented.

Second, the quote is inaccurate – we are not planning on generating ZEV revenue from every Model S we sell. ZEV credits are available for sales of qualifying vehicles in California and twelve other states. Vehicle sales into other states and other countries do not earn such credits.

In fact, we are selling our Tesla Roadster today in 28 countries which makes sales into the thirteen ZEV states far less than half of our total sales. We’ve told investors that we expect to have almost 50 stores around the world over the next few years, so it would be very reasonable to conclude that sales of the Model S into ZEV states in a few years might be just a fraction of our total sales. As a result, it would also be reasonable to conclude that we are not dependent on ZEV revenue from those sales. We certainly don’t believe that the absence of ZEV credit revenue threatens the viability of the Model S.

We hope this presents a more balanced perspective on the role of ZEV credit revenue to Tesla.

Teslas Finish 1-2 In Electric Rally

A pair of Tesla Roadsters finished one-two in a four-day rally race through the Alps.

The e-miglia was a riff on the classic Mille Miglia of yore that saw 25 EVs of every description set out on a run from Munich to Roverto, Italy. Six cars didn’t complete the 560 kilometer (about 347 miles) race, which was more a measure of efficiency and timing than flat-out speed. The point was to reward constancy and reliability — i.e. completing stages as closely to a specified time as possible.

Tim Ruhoff and Steven Hofmann of team Energiebau took top honors in a Tesla Roadster Sport with a total time of 37 hours, 30 minutes and 1.59 seconds. They took home a check for £10,000 (about $13,226). Carlo Bermes and Wulf Biebinger of JuWi Racing were just 2 minutes and 18 seconds behind in a Tesla Roadster.

Third place went to Markus Spiekermann who was driving solo in a Think City. He crossed the line 4 minutes and 27 seconds behind the leader. We love the idea of a Think City in any kind of race, let alone a rally.

Judging from the schedule for each day, there were two stages daily. Competitors would drive in the morning, then charge for four hours, then drive until evening. We imagine a climb through the alps will make quick work of a battery.

Organizers said the point of the race was to “show how capable and appealing e-mobility already is.” A noble goal indeed, but we’d have been there just to drive a Roadster Sport through the Alps.

Sailplane Launches Itself With Retractable Jet

A creative bunch of tinkerers think the recent trend of self-launching gliders needs a bit of a boost. So instead of outfitting their high-performance sailplane with an electric or small piston motor, they’ve attached a jet engine that folds neatly into the fuselage.

Traditional sailplanes have no motor. They’re typically towed to altitude by an airplane or a very big winch. Once high enough, the pilot detaches from the towline to begin the search for the rising columns of air, known as thermals, that can keep the sailplane aloft for hours.

But having to coordinate with a tow plane can be a hassle on a busy day. And then there is always the problem of “landing out.” Often a pilot will push his or her luck in the elusive search for invisible lift and find they are too low and too far from a proper runway. That means landing in a field somewhere and getting the sailplane back to the airport.

Over the past few decades self-launching sailplanes have become popular with pilots who want the ability to reach soaring altitude on their own, or have the ability to save themselves from landing out if they push their luck on a cross country flight. Now they can save themselves with a bit more thrust than the competition.

Chevrolet Volt: Let the Gouging Begin!

If you thought $41,000 was a lot to pay for a Chevrolet Volt, what would you think of $61,000?

That’s how much one Southern California dealership wants, according to Edmunds.com. The site emailed an unnamed dealership to inquire about getting a Volt and was told that demand is so high it is asking $20,000 over MSRP.

Some 600 dealers have signed up to sell the Chevrolet Volt when it is offered in seven markets — California, New York, Michigan, Connecticut, Texas, New Jersey, and the Washington, D.C. area — later this year. General Motors is barred by law from telling dealers what to charge for the car, but it is urging them to stick to the manufacturer’s suggested retail price of $41,000. That comes to $33,500 after the $7,500 federal EV tax credit.

It appears not all of them are doing that.

Rocket-Powered Personal Helicopter Emits Only Water

One of the more, um, unusual designs to emerge in the ongoing pursuit of personal flying machines combines two awesome ideas we don’t see often enough: Rocket and helicopter.

As menacing as the combination might sound, the Dragonfly is rather tame. It’s super-simple to fly and uses two small but powerful hydrogen peroxide motors mounted at the tips of the rotor. The engines are small, just 8 inches long 1.5 pounds apiece. But don’t be fooled by their diminutive size. This baby will top out at 100 knots if you’re really pushing it.

“Each engine is equivalent to 102 horsepower,” says Ricardo Cavalcanti, the man marketing the latest iteration of an idea that’s been bouncing around since the 1950s. “So 204 horsepower to move a unit that is only 230 pounds.”

And the exhaust? Water vapor.

Oh, Deer! Utah Uses Strobes to Fight Jaywalking Bambis

The Utah Department of Transportation is trying an unusual high-tech way to stop that deer in your headlights from acting like, well, a deer in the headlights.

The system, called DeerDeter, is triggered by light from oncoming cars. It uses sound and small strobe lights to deter deer from crossing the road, an animal behavior concept clearly borrowed from Monty Python’s Confuse-a-Cat, Ltd. Since the system is activated only by headlights, it won’t interfere with deer migration patterns as they cross lonely roads.

State officials have been testing 100 DeerDeter units along a stretch of Highway 191 in Monticello, an area known for a high number of collisions between deer and automobiles. As many as 300 dead deer must be removed from a 30-mile stretch there each year, which explains the state’s willingness to try the technology.

The state reportedly bought 70 DeerDeter units at a reduced price. The remaining 30 were donated to further test the technology. To measure its effectiveness, Utah DOT has installed infrared cameras to observe how deer react. Jafa Technologies, the company that makes DeerDeter, says the sound simulates the cry of a frightened animal and the strobes simulate the reflection of a predator’s eyes.

Jafa has installed the system in Europe, and claims it has reduced deer collisions 90 percent in areas where it was implemented. The Insurance Institute for Highway Safety says there are 1.5 million deer-vehicle collisions annually (.pdf) resulting in 150 deaths, so a successful trial run could mean DeerDeter is coming to a wooded highway near you.

The system also is being installed in Essex County, New Jersey, and have been used in Denver and in Fort Dix, New Jersey. While Utah DOT stresses it’s far too soon to draw any conclusions, there has yet to be a deer carcass removed from the test stretch of 191 since DeerDeter has been installed — good news for everyone.

Especially the deer.

DIY Datsun EV Does the Quarter in 10.4 Seconds

Let those who doubt the performance possibilities of an EV gaze in awe upon White Zombie, the DIY EV from Oregon that’s just done the quarter mile in 10.400 seconds at 117.23 mph.

That’s supercar territory, folks.

Anyone who’s been following the EV scene knows about John “Plasma Boy” Wayland and White Zombie, the 1972 Datsun 1200 he’s been running for 16 years. This thing has long been a force to be reckoned with in the National Electric Drag Racing Association. Wayland has been a member of the organization’s 100 MPH Club since May 9, 2004, when he did 100.76 mph.

This year, Wayland dumped the A123 Systems battery he’d borrowed from KillaCycle in favor of his own pack. He’s running a 22.7-kilowatt-hour lithium manganese cobalt polymer pack comprised of 192 Dow/Kokam cells. It is nominally rated at 355.2 volts.

The juice goes to a Siamese 9 motor with a Zilla Z2K 2,000 amp controller. Wayland also reworked the suspension and rear end — a modified Ford 9-inch setup — to handle the power.

Wayland brought the car to Portland International Raceway on Friday. According to the first-person account posted at EV World, things got off to a rough start with some electrical gremlins. Once he excised them, the car peeled off an 11.111 second-run at 117.77 mph. That was a full three-tenths of a second faster than the car’s previous best time.

Six minutes later he did the quarter in 11.069 at 117.70.

And then, disaster. During his third run the wiring to the forward/reverse switch on the dash shorted, shutting off power. Despite the failure, the car still recorded a time of 11.170. An hour in the pits and White Zombie was ready to roll. Wayland and his crew fixed the short, boosted the power to 1,800 amps and increased the motor current to 2,000 amps.

That did the trick. Racing against a Nissan GT-R with 485 horsepower, the little Datsun tripped the timer at 10.400 and 117.23 mph. And the GT-R?

It was about a second behind.

Sikorsky X2 Breaks Helicopter Speed Record

Two hundred and fifty-nine miles per hour. That’s how fast the Sikorsky X2 flew during a recent test flight in Florida. The flight broke a record that had stood since 1986 when a Westland Lynx managed 249 mph.

And Sikorsky isn’t done yet.

The X2 is a technology demonstrator aimed at developing helicopters that easily cruise up to double the speed of traditional helicopters. Using a twin rotor design, a pusher prop and numerous aerodynamic improvements, Sikorsky says this type of design could lead to helicopters that are easily capable of even higher cruise speeds.

After setting the helicopter speed record with the 259 mph flight, X2 program manager Jim Kagdis said the helicopter is performing better than expected so far.

“Vibration levels and aircraft performance have continued to meet or exceed our expectations, so we are pleased to report that all systems are ‘go’ in our mission to achieve a 250-knot [288 mph] cruise speed later this year,” he said.

Helicopters traditionally are limited by the complex aerodynamics created with the moving rotor blades losing lift when they are moving backwards relative to the direction of flight. A propeller at the rear of the helicopter allows the X2 pilot to fly at higher speeds while minimizing the problems associated with high speed flight and the main rotors.

Sikorsky believes there is a marketplace for a fast moving helicopter in the military and civilian world. Both markets are interested in faster medical helicopters to reduce response times for transporting patients in and out of remote areas. The company hasn’t released details about plans for a production version of the X2, but has said the technology will find its way into a future model.
