On the contrary re your opinion, what you say actually sits well with me although I must say I'm learning more and more about the geothermal sector.
From the rather cursary research I have carried out on some of the others KEN does appear to have the edge for the reasons already discussed so I'm comfortable with my investment.
The more I learn though about the sector is that there are indeed much more learned individuals than I seeing the potential and as such increasing their positions accordingly.
Patience really is the name of the game as you've alluded to so let's just wait and see I guess, mind you thus far the future is looking brighter I must say despite the uncertainty that exists regarding renewable energy presently.
If you're inclined check out the publications by the likes of Thomas Friedman and Paul Gilding for a clue as to where geothermal is likely headed ;)
