Thanks, but i cannot help thinking the other way. 1) rio tinto,world largest uranium producer mining 16% of the world nuclear fuel 2) Areva number2 with15% market share 3) Cameco. Nuclear is not over for at least 20 years, but needs to be cleaner and safer.. i think zen can provide a solution wich was not excisting yet, hence the slow progress. batteries might be an alternative but as fat as return is concerned less atractive for ZEN We wait to see.kind regards,inca.
