Dr. Peter Heffernan:

At one point we had two devices on site at the same time. A number of developers have run into the classic valley of death on the funding cycle. The information is commercially sensitive so I do not know how the individual devices have proven. The market will test that in terms of how well they can raise finances. To the best of my knowledge there were five indigenous devices in various stages of development when last I checked. It is something that will be very much a trial and error process for some time to come.
