Is SPD a "concept" technology?

Is REFR getting typecast?

Between the Jeep Rescue, the Juno, let's throw in the Kabura even though it was never established as SPD, and now the Hino S'elega Premium, SPD is establishing a considerable track record as a demonstration technology. But, with its subsequent failures to cross the gap into the real market, one has to wonder if it can ever do so.

Certainly, anyone considering SPD technology and researching it would have to be well aware of both SPD's proliferate demonstrations and dearth of market applications. Just as certainly, they could not be blamed for thinking to themselves, "SPD gets evaluated a lot, but never makes it into the market. Does that mean people are finding something wrong with it?"

That actually might partially explain the almost immediate reversal of the news that SPD is in yet another concept vehicle. Is there not a growing risk that prospective customers going to start thinking that maybe demonstrations and concepts are all SPD is actually good for?

Maybe SPD has reached that point and maybe it hasn't. But that's a concept Joe Harary and company really ought to consider carefully, before hauling SPD off to the next trade show demonstration.
