The conference promotes transatlantic dialogue between businesses, universities, research centres, investors and political leaders. Organizers say they gathered 200 European and US Green Tech companies from 44 countries for the event (http://www.labaulewic.org/awards/award_green_platform.asp).

Twenty of them were reviewed by an international ten-member jury and evaluated according to criteria such as innovation, technological excellence, capacity of internationalisation, maturity of development, growth and market potential.

“Perpetuum had particular high scores on the innovation and technology criterion and on growth and market potential. The company has developed a “vibration harvesting technology” which converts waste energy from vibrations into useful electrical energy. The jury valued the fact that the managers were able to first prove the validity of one market before looking at other promising applications aimed at different market segments. The conclusion was that this is a proper controlled growth development,” said Jean-Pascal Tranié, Founder of Aloe Private Equity, Moderator and member of the Jury, La Baule.

Perpetuum has commercialised the “PMG17,” a microgenerator that converts mechanical vibrations into electrical energy to power industrial wireless systems. Harvesting power locally makes the wireless system independent from the use of batteries or mains power and drastically reduces installation and maintenance cost.

The device opens up the market for many wireless network implementations even in hazardous environments due to its intrinsically safe design and ATEX (zone 0) certification. The environmental benefits of monitoring industrial motors for efficiency loss are potentially massive. According to the U.S. Department of Energy, monitoring and improving the efficiency of industrial motors could save an estimated 122 trillion Btus by 2020.

“This award is confirmation to our customers that our technology is not only green but also a decisive breakthrough for enabling truly wireless sensing without batteries.” says Roy Freeland, CEO Perpetuum.
