250th Delivery

Peter Denbigh sent me the article below:

250th Delivery

Tesla Motors delivered its 250th car last Saturday. Lucky No. 250 was Dr. Rob Wilder, an academic and entrepreneur who created the first Index on Wall Street for energy efficiency and zero-carbon solutions. Rob lives in Encinitas, Calif., where he charges his Roadster from his home’s array of solar panels. He picked “very orange” as the exterior color to symbolize the car’s connection with the sun.

“We’re not beholden to Middle East oil – and by the way my car is probably faster than your car!” joked Rob, CEO of WilderShares LLC and manager of WilderHill Clean Energy Index, the first Index on Wall Street for energy efficiency and zero-carbon solutions. “This car is an elegant solution to some of the world’s most difficult problems. And buying it is helping push along EV adoption generally because Tesla is investing the money in lower-priced cars down the line.”

Rob’s new car marks a symbolic milestone for Tesla and a personal first for Rob, who previously tended to purchase used cars for no more than $13,000 each. In fact, the Roadster is more expensive than all of his previous cars put together.

“I took a big, big gulp and sent in my check – and although this car may not seem like a bargain, I can now say it’s a great value. This is exactly the type of car I’d design for myself.”

Tesla is now producing approximately 20 cars per week, which will increase to 30 per week this summer. About 1,000 people are waiting to take ownership of their Roadster, which means Tesla is sold out through October of this year. The Roadster remains the only highway-capable production electric vehicle of any kind (not just in the sports car category) for sale in the US or Europe. It does 0-60 in 3.9 seconds yet is twice as energy efficient as a Toyota Prius.

Model S Update

Tesla will unveil its Model S prototype sedan March 26 at the Tesla design studio inside the SpaceX rocket factory, in Hawthorne, Calif. This is going to be a historic event for car enthusiasts; the Model S will likely be the world’s first mass-produced, highway-capable EV when it rolls off the assembly line in late 2011.

The Model S will have an anticipated base price of $57,400. After a federal tax credit of $7,500, the effective price will be $49,900. Because of tax incentives and relatively inexpensive maintenance and refueling, the lifetime ownership cost will be closer to cars with far lower sticker prices. Tesla executives will provide a lot more product details at the launch party in Southern California, home to Tesla’s design studio and the world’s largest new-car market. The Model S will become the car of choice for environmentally conscious and discriminating drivers throughout North America and Europe. Tesla expects to roughly split initial sales between the two continents, later expanding to Asia.

New Digs in Chicago

Tesla announced earlier this month it plans to open a Midwest regional sales and service center in Chicago, the first of seven retail facilities the electric vehicle manufacturer plans to launch this year.

The Chicago store — which will open this spring — is at 1053 W. Grand Ave. in the River West neighborhood. The location gives prospective customers the opportunity to experience Tesla’s best-in-class performance under a range of driving conditions, including highways and urban streets.

After Chicago, Tesla plans to open a store in London’s Knightsbridge neighborhood. We are also finalizing site selection in Manhattan, Miami and Seattle and scouting sites in Washington, D.C. and Munich, Germany. These stores will expose more people to the Roadster – and most importantly they will serve as a lean and efficient retail footprint as we get more mainstream customers for the Model S.

One reason Tesla service centers will be smaller than gasoline car service centers is that the Roadster has far fewer moving (and breakable) parts than an internal combustion engine vehicle. It doesn’t require nearly as much service and maintenance as gas guzzlers, so Tesla doesn’t need cavernous service and repair bays and large spaces to store spare parts. Tesla requests that owners bring in the car – which never needs oil changes or exhaust system tune-ups, among other costly repairs — every 12,000 miles or once a year for a diagnostic check and software upgrade.

Tesla Heads North

Earlier this month, Tesla began selling cars in Canada. We will begin delivering cars in the fourth quarter, and we believe Canada will become a premier showcase for the Roadster. In Canada, the majority of electricity comes from renewable resources, including run-of-river small hydro, wind, biomass, geothermal and solar energy. An EV recharged from the current Canadian grid, on average, would reduce greenhouse gas emissions by about 85 percent compared to an equivalent gasoline-powered vehicle. In hydro-dominant British Columbia, Quebec and Manitoba, the reduction would be an impressive 98 percent.

Canadian Roadsters will comply with all national and provincial safety regulations for mass-produced, highway-capable vehicles – and they’ll perform in the snow, just as they already do in Northern Europe. The base price for Roadsters in Canada will be set closer to the start of deliveries, and pricing will reflect exchange rates at that time. In the United States, the base price is $109,000.

Thanks, and please be on the lookout next week for official Model S photos and video — and more exciting news from Tesla in the weeks and months to come!

Cajun Crawler: the Segway gets a leg-up

Wednesday, March 18th, 2009

Gizmag.com has this interesting article about University of Louisiana students putting legs on a Segway and making a vehicle that literally “walks.” This is a fascinating project. Go to http://www.gizmag.com/cajun-crawler-segway-concept/11259/ to see it.

March 18, 2009 Take one DIY Self balancing electric vehicle project, replace the wheels with 6 pars of short legs based on Theo Jansen kinetic sculptures and the result looks like something out of “Hitchhikers Guide to the Galaxy”. A dynamically stabilized, ride-on robot that crawls.

The Cajun Crawler was built by a team of mechanical engineering students at the University of Louisiana and was inspired by Theo Jansen’s leg mechanism. During their research the students found no application where Jansen’s leg mechanism was used in a weight-bearing application or on a vehicle.

The six pairs of insect like legs are machined from 5052 Aluminium and driven with two 18V hand-drill motors that drive the legs via a crankshaft. The electronics and battery packs from the cordless drills were also used to power the crawler. The Cajun Crawler uses the same Dynamic Stabilization used in the Segway, but the multiple feet give it a more stable platform with a top speed of 3mph.

The materials used to make the Crawler cost approximately USD$1100-1200 in total. Thanks to the low cost of microcontollers and electronic components DIY Segway projects have become a popular choice in university mechanical engineering labs around the world with many variations on the idea but this is the first we have seen that crawls.

The original Segway came out of the first product that used Dean Kamen’s balancing technology, the iBOT wheelchair which could climb stairs. We shall have to wait and see if any students try to build a balancing robot with human sized legs.

Check out the video of the Cajun Crawler in action below.

Engineering Students Build And Design A Fuel-Stingy Vehicle

Sunday, March 1st, 2009

This article was on the ScienceDaily website today.  From below:  “The team hopes to improve on the current Dalhousie record of 420 kilometres per litre on regular unleaded gas, with a vision to beat the record at the Shell Eco-marathon Americas of 1,445 kilometers per litre.” 420 km/l equates to 988 mpg and 1445 km/l equates to almost 3400 mpg.  Maybe the AFV Lab Supermileage team can get some ideas from this article.

Engineering Students Build And Design A Fuel-Stingy Vehicle

ScienceDaily (Feb. 28, 2009) — With its light body made of Kevlar, sleek aerodynamic design and three Olympic-racing wheelchair tires, it looks like something that escaped from the Batcave.

But actually it’s a school project by a team of six Dalhousie University senior mechanical engineering students.

The ultimate in fuel efficiency, the “Maritime Mileage Machine” will be entered in the 2009 Shell Eco-marathon Americas taking place on April 15 to 18 at the Auto Club Speedway in Fontana, California. The event challenges high school and post-secondary students across Canada, the U.S., Mexico and South America to design and build a vehicle that will drive the farthest using the least amount of energy.

The students who win will have a chance to make history and take home thousands of dollars in prize money.

“The main thing is to keep it simple and efficient,” explains Matthew Harding, the team’s manager. Other members include Liam Jeffrey, Craig Arthur, Chad Batterton, Brad Marcus and the driver Carmen McKnight. “The whole point of the competition is maximum fuel economy.”

The vehicle runs on a 35-cc engine—“It’s basically a big weed whacker,” says Mr. Harding.

The team hopes to improve on the current Dalhousie record of 420 kilometres per litre on regular unleaded gas, with a vision to beat the record at the Shell Eco-marathon Americas of 1,445 kilometers per litre.

“Considering the average car is getting about 30 miles per gallon (or 13 kms per litre), that’s pretty drastic.”

Carmen McKnight, selected for her petite size, will drive the vehicle while lying in a hammock-like seat with a headrest to prop up her head. She steers the car using handles on either side of her body.

Circuits are about seven miles long and the race will last roughly 45 minutes a circuit.

The team’s goal is to fine-tune their model and get in some practice time to be ready for the competition in April.
