AFS Trinity Flywheel Concept Car
AFS Trinity's initial vision was development of a flywheel-assisted hybrid that could 'fast capture' virtually all of the vehicle's kinetic energy, which a conventional battery-hybrid can't do as efficiently. The company is now proposing to develop a battery that leverages the high-power efficiency of ultra-capacitors with high-energy, advanced lithium-ion batteries.

Extreme Hybrids Ahead

Interview with AFS Trinity Chairman and CEO Edward Furia about the alliance with Ricardo to develop V2G plug-in hybrid drive systems


By Bill Moore



Open Access Article Originally Published: January 31, 2006

Edward Furia's AFS Trinity has been lying low, perfecting technology and building alliances, waiting for the opportune moment to pounce.

That moment came on January 25, 2006 when the Bellevue, Washington company issued a press release announcing that it and world-renown auto engineering firm, Ricardo, had quietly joined forces late last year to not only develop a plug-in hybrid, but a vehicle-to-grid or V2G hybrid.

The event that caused the Furia to surface with his announcement was the Plug-in Partners press conference the day before at the National Press Club in Washington, D.C.

I immediately contacted Furia and arranged to do an interview, which took place on Friday, January 28, 2006. I expected to talk with him for 20-25 minutes, but instead we went nearly an hour in one of the more informative and entertaining telephone discussions I've conducted for EV World. I will attempt to summarize the main points of our dialog, but I strongly encourage you to listen to it in its entirety using either the MP3 Player on this page or by downloading the file to your computer hard drive for transfer and playback on your favorite MP3 device.

EPA and Earth Day
Ed Furia was a senior EPA official for the mid-Atlantic states in the early 1970's. He was instrumental in helping bring about the first Earth Day, as well as the 20-year commemorative celebration.

He explained to EV World that back in 1989, his former EPA press secretary, Tim Kent, introduced him to the concept of powering electric vehicles with advanced flywheels, rather than just batteries.

"At the time, I declined to get involved", he said, "because with my experience in the government, I believed there was too much institutional inertia, both in Detroit and Washington for one to successfully introduce an alternative to the standard internal combustion engine-driven car."

It would be a convergence of several different events including the 20th anniversary of Earth Day, the debut of the General Motor's Impact electric car, which became the all-too-short-lived EV1, plus Congress' amending the Clean Air Act in 1990 that would cause him to re-evaluate his views.

"The thing that pushed it all over the edge was (Iraq's) invasion of Kuwait by Saddam Hussein. That rekindled concerns about the instability of that part of the world from which we were getting the oil and gasoline for our cars."

   For every plugged-in hybrid, there is enough battery material to build 5 hybrids. Thus, when there is still a shortage of battery, the emphasis should be to build super-efficient gasoline-electric hybrid THAT CAN BE EASILY CONVERTED TO PHEV WHEN BATTERY WILL BE AVAILABLE IN UNLIMITED AMOUNT. The simple approach would be to have the front end powered by an ICE connected to a small CVT, and the rear wheels driven by electric motor(s). This will give an efficient electric-only mode as well as overall high efficiency in the ICE mode while not violating Toyota's patented HSD design. It looks like Mitsubishi is on the right track on something like that. -------------------------------------------------------------------------------------------------------------- I can't see the advantage of a flywheel nor a supercapacitor when there is already a sufficient-size battery on board. For example, the Prius II has only a 1.3kwh battery, yet it is capable of putting out a whopping 21kw of power, and the battery is warranted for 10yrs or 100,000miles. Just imagine how much power a 9kwh-battery can do.

   Roger, it is possible (likely) that in order to maximize kWh/kg they will sacrifice the kW/kg ratio. In other words, the battery holds a lot of energy, but it needs a capacitor to increase power (during acceleration). Increasing the energy content of a battery does not increase its power.

   So do I Serafino. A PHEV with enough batteries for 100 Km would not need a very large (cellelusic) ethanol ICE range extender generator.

   Thanks for this article and audio. I think Ed's dialogue/monologue ;-) was very informative and gives folks like me a peek into how things flow in the automotive industry. I wish him success so that by 2010 we will have plug in hybrids available across many platforms and car manufacturers at an affordable price. I hope Ford embraces this as key to their recovery strategy and uses it as a way to get at least one American car company in a position to leapfrog the Japanese. We can only hope -

   Great article. I don't understand any of the mechanics but I do understand the importance of reducing our dependence on oil. Where can I buy one of these cars????
