i follow the sector somewhat, and have small stakes in qtww and ca;fct. fct intrigues me greatly. they have no money and limited sales so it's very early. they have what's called a SOFC--solid oxide fuel cell. runs at high temp. and must be stationary. however, as production scales and costs drop, they may be positioned for residential applications in areas where electricity is expensive. i am monitoring them for a breakthrough as they're less than .30 canadian! i can send a research report if you give me your email
