Student news: Going green, one moped at a time
Vespa scooter
A Vespa scooter is a scooter with a history—it’s credited as the affordable form of mass transportation that reignited Italy’s post-World War II economy. The scooter’s unique, timeless design makes it the “Rolls Royce” of scooters, an heirloom that can last 20 years in the care of a faithful owner.
Yet, even for a Vespa, there’s room for improvement, and 16 University of Wisconsin-Madison engineering students spent last fall figuring out how to make the already environmentally friendly Vespa even more green.
While enrolled in civil and environmental engineering professor Marc Anderson’s section of Inter-Engineering 160, Introduction to Engineering, the students designed, built and tested a hydrogen-based system that ultimately reduced the amount of gasoline necessary to run a Vespa moped by 10 percent. The system is based on electrolysis, the process of splitting water into oxygen and hydrogen via an electrical charge.
“As freshmen, they’re just starting to get used to things, and I usually pick out projects that are difficult so they’ll learn a lot,” says Anderson, adding the project offered exposure to environmental engineering, mechanical engineering, electrochemical engineering, materials science and construction engineering.
The students experimented on a yellow 50-cc steel-body Vespa moped provided at a substantial discount by Jeff Dunn, the owner of Vespa Madison at Dunn’s Import in Middleton. While the bike already averages 90 miles to a gallon of gasoline, Dunn says even Vespa needs to do better environmentally, and he’s more than willing to help the students.

“I think what they’re doing is very exciting. I believe wholeheartedly that it’s good for Vespa,” he says.
The students divided their work into three components: the electrolysis device, the battery and the engine. For the electrolysis device, they designed rectangular electrodes to split the water using carbon plates coated with a nanoparticle thin film Anderson developed. They set the plates inside a container called an electrolyzer, which they positioned near the moped engine beneath the driver’s seat. The electrodes are powered by a charge from the moped’s alternator and separate the water into oxygen and hydrogen, funneling the hydrogen directly to the engine’s cylinder via a stainless steel tube.
Once in the engine, the hydrogen produces a more complete combustion, according to Anderson, which means the engine more efficiently uses the fuel.
The electrolyzer system could, in addition to reducing the amount of gasoline necessary, also reduce moped emissions. While the students did not have time to test emissions levels their system produced, Anderson anticipates the more complete combustion caused by hydrogen in the engine would make the moped run cleaner. From here, the electrolyzer system may benefit the UW-Madison vehicle teams, which frequently experiment with hybrid vehicle technologies. In fact, mechanical engineering faculty associate Glenn Bower, who oversees the vehicle teams, offered additional advice and support to the moped project.
Not all college freshmen delve into their majors via practical, hands-on projects in their first semester on campus, and the experience has been valuable for mechanical engineering freshman Steven Burbach.
“The project was very cutting-edge—we weren’t building things that had already been done, and I really appreciate Professor Anderson’s willingness to trust us with this,” he says. “Engineering isn’t just sitting at a desk. It’s getting out there, tackling real-world problems.”

The Race for Cold Fusion - Breakthrough!
Watch CBS Videos Online
Welcome to Energetics Technologies SuperWave™ Fusion - a pioneering technology that current research suggests may prove to be a revolutionary approach to the generation of clean, abundant energy. This technology appears to produce an astonishing 25 times more energy output than the energy required to produce it.
Imagine a clean technology that promises to produce cost effective energy without having to rely on fossil fuels or access to wind or sunlight.
Energetics Technologies is the innovative company offering this historic breakthrough that could result in a dramatic increase in energy availability when compared to fossil fuels, wind, hydro-electric, and solar technologies. Energetics Technologies opened the doors on its research laboratory in January 2002 to apply a new principle fundamental excitation concept to electrolytic cell operation and began obtaining excess heat in an electrolytic cell within 6 months.
This is their story. This is our future.

Hydrogen Boost System Powered By Cars Exhaust
Here's for the naysayers who keep discouraging modern day Einsteins to stop pursuing what we are pursuing.
This is a not so old technology used by cooling/heating companies... it is also widely used as PC component coolers... and or heater.
Peltier effect is about utilizing the thermal difference to produce instant electricity in DC form.
And if there is electricity, you can produce instant heat or cooling as well.
These type of devices have been considered low in efficiency in the past until now.
The alternator current draw and load placed by th hydroxy electrolyzer has been the primary issue used by the technology suppressors since time immemorial... I have kept ensciro's video in my on hold list for a while before posting it here in my blog... in fact, it may not be related directly but it is a distant cousin of hydroxy on demand systems.
Having a background in Thermodynamics will indeed make one appreciate this approach of utilization.
For the enthusiasts - you can put this into your armory.
For the detractors - We are not saying the earth is flat...you are.
For the believers - just have faith - revelations are coming soon.
Next topic to write... is probably about efficiencies.
Thank you for reading. I hope you learn something again here.
