Speed record set for all-electric airplane – 204.4 mph

Chip Yates does not like sitting still. Just a day after piloting his electric-powered Long EZ airplane to over 200 miles per hour – making him the fastest electric-airplane pilot in the world – he had to disassemble the airplane, pack it up and drive 2,000 miles east to Oshkosh, Wisconsin. Here at Airventure, Yates continues to be busy answering questions about his record-setting run. And perhaps one of the more surprising answers is that Yates is a not a veteran test pilot. He just got his license in June and has about 58 hours of experience, including the record-setting run last week.

When the electric vehicle pioneer bought the used airplane it had a 118 horsepower, four-cylinder gasoline-powered engine that is fairly standard for a Long EZ. Over the course of several months Yates and his team pulled the four-cylinder engine out of the Long EZ. They then pulled the 193 kW (258 hp), liquid cooled electric motor out of his record setting battery powered motorcycle and mounted it to the back of the Long EZ.

With the very well used (Yates calls it “abused”) lithium polymer battery back from the motorcycle in the back seat, the Long EZ was being prepared as a test bed for some of the technologies Yates needs to develop for his transatlantic flight. But after setting speed records for an electric motorcycle, first up for the Long EZ was a speed run.

Wikimedia Foundation votes to start a travel guide – as Wikitravel implodes

The Wikimedia Foundation has decided to create a travel guide in the mold of its non-profit, user-written and search engine results-hogging Wikipedia.

The foundation’s board of trustees on July 11 approved a proposal to launch an advertisement-free travel guide and noted that 31 of the 48 administrators of the Internet Brands-owned Wikitravel have pledged to join forces with the Wikimedia Foundation’s travel guide website.

The foundation indicated that Wikitravel is the current leader in travel wikis, but its advertisements and monetization efforts may turn off travelers and would-be contributors.

In addition, the foundation argues that Internet Brands has failed to keep pace with the times and that Wikitravel suffers from a “lack of technical support/feature development.”

Jani Patokallio, a Wikitravel admin based in Melbourne, Australia, wrote about the editors’ mass exodus from Wikitravel, and told Skift that the situation there had reached “the boiling point.”

College competition racing Baja off-road vehicles

A group of students in gray shirts file out of a cramped classroom onto the road. Shining flashlights to see through the darkness, they huddle around the frame of a short, black car.

One yanks on the pull start.

The engine roars to life, and the car takes off down the road, ready for competition.

The vehicle will race this week at the Baja Society of Automotive Engineers regional competition in Oregon. The competition challenges collegiate teams to design, build and race an off-road vehicle, testing the cars in categories such as maneuverability, acceleration and endurance.

***

Each car in the competition must be built using the same type of engine, but the design of other parts such as the gear box and transmissions are up to each team, said Dylan Aramburu, a second-year mechanical engineering student on the UCLA Team. This gives teams the opportunity to fabricate their own customized parts.

A lot of teams buy gearboxes to put in their cars, but UCLA’s Baja team makes its own from scratch, said Anthony Tyson, a fourth-year mechanical engineering student and one of the project leaders for the team.

SimCity 2013 – goes green with limited resources, pollution, and sustainable principles

Any computer gamer old enough to remember floppy disks probably paid at least a fleeting visit to SimCity, the legendary franchise that let players build — and destroy — the metropolises of their imaginations. After passing through half a dozen incarnations in the two decades since its debut, the game is back, and its creator, Maxis Studios, says that this time, it’s putting more than bricks and mortar into the mix.

Slated for release in 2013, the new SimCity invites players to grapple with tough choices about energy generation, environmental costs and the responsibilities shouldered by inhabitants of a planet with finite resources — choices faced by real policymakers on the very real planet Earth.

To the game’s original repertoire of fire stations and governor’s mansions, power lines and city budgets, Maxis is adding a cocktail of new challenges, including limited resources and the spillover effects of pollution.

Nissan LEAF, electric cars means no oil changes, no tailpipe, and a big market for "charging stations"

The all-electric Nissan LEAF is coming soon to a neighborhood near you. It’s a fascinating new car with many exotic features, as compared to our normal gas-engine cars.

To learn more about it, I’ve pulled out some of the more interesting Frequently Asked Questions. After reading them one realizes that we are facing some serious changes:

  • A new smaller engine that requires no oil or transmission fluid, no gas tank, and no tailpipe. I guess the interior will be bigger?
  • A new breed of mechanics will be required to fix electric engines and repair battery issues. Hot new job?
  • Charging stations, these places should start popping up all around our city.
  • Will they be private or publicly owned (currently most are publicly owned)?
  • Do you think the name will stick, charging station, or will it be the electric station?
  • Zero emissions while driving and a reliance on electricity, which is much cleaner than gas.
  • View pictures of the charging port, interior, and dash.
