WFI Industries is involved with geothermal heating and cooling for residential and commercial application. It is managed well and has a 30% ROE. It is a good long term investment.
Geothermal heating for homes. There is a high installation cost but is virtually cost free to run. Revenues have been rising significantly, but got hit by a US housing scare. Probably a takeout candidate.
Geothermal play. Was very attractive when gas prices were $12-$13. The shine came off when gas prices dropped. Thinks gas will go significantly higher so geothermal is the way to go. Very attractive dividend.
Water out of the ground to heat furnaces in the winter and cool in the summer. Very interesting product. Will probably mark time at the moment. In the bottom 2/3rds of his database.
