re: market absent and hpdi I agree completely. It is difficult to assess how well the development is going. The company will, of course, put a positive spin on it. I'd love to talk to one of the mechanics at either Bobell or Norcal. The question was asked by one of the "analysts" during the conference call. Guff's response was that they just "love us there", skirting the issue. I would think norcal does love them. I imagine that every time something comes up the wpt team jumps to correct it. What we are really doing here is gambling that the technology will work. If it doesn't then wpt is a bust. JV sales of spark are just window dressing, especially now that money has been raised by way of the new offering.
