The Mantra Energy Spark was real, and Alstom power threw another $120,000 at Mantra because of the Spark, and upped the Spark fuel cell energy density by 400% with that funding,but Alstom (GE by then) would not let them make it public.
That was why Alstom power worked like the devil to get a deal with a handful of firms in Europe the last 18 months to sponsor the ERC-fuel cell combo for energy storage.
I know what I know.
Cheap oil and Nat Gas made it hard to get the deal done in the time Larry had left....Before GE pulled the Plug.
Ponder and Keith blew a huge opportunity and traded it for a Wave-Scam IMHO.
