Interesting numbers


Many names for the same concept: ultracapacitor, supercapacitor, ultracap, supercap but always we spoke about the new energy store, capitor used to also boost this Zap production.
The number of this all-electric car start to be interesting:

Drive Train
100% Electric; 4 electronic wheel hub motors sporting an aggressive 644 horsepower with super capacitor energy bursts

Speed
0 to 60 mph in 4.8 seconds with top speed of 155 mph

Mileage & Range
350 miles per charge; about 1 cent per mile; rapid 10 minute re-charge; 9,000 life cycle

No batteries but ultracapacitors

In the 2003 was said:

"An ultracapacitor-powered electric vehicle built by Brigham Young University students made history at the National Electric Drag Racing Association at the Las Vegas Speedway last month. Crossing the quarter-mile mark at 15.907 seconds, the highly modified electric car set a world record for modified production vehicles running more than 241 volts. The ultracapacitor functions of the vehicle were designed and built by the BYU students after General Motors donated an electrical car named "EV 1" to the university. The car had many parts missing, which provided students with the project of designing and rebuilding components of the car. "The purpose of the project was to involve students in trying to solve problems. Our goal was to see what the team could do with ultracapacitors," said Tom Erekson, director of BYU's School of Technology.".




In the 2007 Honda uses the ultracapacitor for the prototype Fuel Cell Power FCX, and the citycar ZENN will be soon powered by ultracapacitor.

Ultracapacitors charges in seconds and offer virtually infinite charging cycles, no maintenance need and an extimated life of 30 years.

World's first battery-powered manned plane



Developed by Tokyo Tech students and Matsushita Electric Industrial Co.

The students-developed manned plane powered by 160 AA batteries flew for 59 seconds covering 391.4 meters and soared as high as 6.11 meters above the ground.

The students are members of "Meister," a club mainly consisting of Tokyo Tech students who are interested in "creativeness." They enjoy extracurricular opportunities producing solar cars, human-powered planes and so on. They are particularly known on campus because of their excellent performances at annual birdman rally, a flight competition for human-powered flying machines.
In January 2006, they were offered by Matsushita Electric Industrial Co. a project to fly a battery-powered plane: a plane not to be remote controlled but to be piloted by a man. What an exciting challenge!
Some "Meister" members and the Matsushita group immediately launched the joint project. Thanks to the students' experience in developing planes for the birdman competitions! A single-seated plane with a 31 meter wingspan but weighing only 54 kilograms was completed in April. The joint team then gave several test flights working to be ready for the demonstration in July.
The demonstration flight was made on July 16 in Okegawa, SaitamaPrefecture. The plane powered by 160 AA batteries took off beautifully and stayed in the air for 59 seconds reaching as high as 6.11 meters.
Kei Horie, a senior student and the student representative for the project, said, "We're extremely delighted to take part in the world's first project." He continued, "It's been really stimulating and inspiring." The pilot, Tomohiro Kamiya, also a senior student, said, "When the project started, I wondered if it would be successful. But I got confident while making several test flights." "Now I'm relieved and feel very happy with the result," he added.
The flight took place in the presence of officials from the Japan Aeronautic Association. The joint team will apply for the official recognitions from both the Japan Aeronautic Association and the FAI (Federation Aeronautique Internationale).
