So, maybe it will be possible to buy them from IndiaOn October 1, 2010, Firefly International Energy Co. has acquired assets of Firefly Energy from the Bankruptcy Estate and resurrected its operations at the same location.Firefly International Energy Co. is backed by solid support of technical vision, manufacturing and customer base from India.
Firefly Energy had assembled a world class organization with unique abilities in advanced Lead Acid Battery technology and products. This included all facets of invention / discovery, specific product development and designs, broad test lab capabilities, as well as battery prototype manufacturing capabilities. These abilities came not only from its personnel, but also its excellent 53,000 square foot prototype and test facility located in Peoria IL.
Firefly International Energy Co. understood these unique abilities and quickly moved to retain key staff, all the equipment, intellectual property, building and facilities, as well as key vendor relationships. The key technical talent, including Mr. Kurtis Kelley, the inventor of the technology, is already back on-board and other former employees are committed to support. Firefly International Energy Co. plans to leverage its strategic relationships in India to make the technology much more compelling from a cost stand point, while retaining core R&D and engineering capability with niche manufacturing in USA.
