inconvenient please do not attempt to shut down the exploratory nature of OZ's posts. This is what we do on this forum. We look at the technology offered by POET and identify potential applications. It is a very significant technology and the radiation hardened nature and efficiency lends itself towards development in many aerospace/satellite applications. If you fail to understand the significance that is fine but I would suggest that you avoid being so critical in how you present your argument to one of the best researchers on this forum.
