COEUR d'ALENE - The latest products and prototypes in energy saving will be the focus of an upcoming convention attracting large overseas governments looking to save money, clean energy enthusiasts and hobbyists, among others.

At the Renaissance Free Energy Convention July 29-31, at The Coeur d'Alene Resort, attendees will learn how they can power their homes, vehicles and other energy-consuming products on a new alternative energy technology and how to restore most useless batteries.

The technology will be demonstrated, and hands-on workshops will be conducted where samples of the technology will be replicated alongside inventor John Bedini and his associates.

Bedini, of Hayden, is an expert in semiconductors and audio systems, and is vice president of research and development at Energenx Inc.

Energenx is the parent company of Renaissance Charge LLC, of Hayden, which is hosting the convention. Renaissance Charge engages in research and development and sells battery chargers and motor generators.

It has customers worldwide, with about half of them in the U.S. and Canada.

Rick Friedrich, general manager of Renaissance Charge, said the first day of the convention will include demonstrations of Energenx's patented motor generator.

The second day will include the workshops.

The final day will include demonstrations of the battery chargers, and a keynote presentation by Bedini.

"This is 100-year-old technology discovered by Nikola Tesla and developed by Bedini," Friedrich told The Press Tuesday.

He anticipates about 500 to 1,000 people will attend the convention. At Renaissance's November convention there were about 400 attendees, he said.

Convention hosts will show off a sports car, a boat, home-power system and lawnmower, all powered by Energenx's patented motor generator.

There also will be a 21-foot Ferris wheel in front of The Resort, which also is powered by the same motor generator.

The cost to participate in the convention is $480 per person for all three days, and includes three lunches and one energy-motor kit.

Attendees also can pay $350 for attendance and participation in all three days of the convention, but no lunches and kit.

There are discounts for residents and students, Friedrich said.

Single-day passes are available for $100.

For $50, people can get access to morning demonstrations on the front lawn of The Resort, where the boat (which will be taking people out on the lake), car, lawnmower and Ferris wheel will be located.
