Death Star I was doing some searching on NASA and the phased array OPEL is working on and I found these:

This sounds like a job for POET. For folks that read the Byron King paper, recall his description of the directed energy weapon that POET could make. Recall also that ODIS has an active PII SBIR for developing a phased array technology it could be a good fit. Here's a line from the second article:
""Our proposal assumes a combination of baseline technology –– where we are today –– and where we almost certainly will be in the future, without asking for any miracles," he explained. "We've really tried to temper this with a realistic view of what we can do, and we approached it from that point of view. It does require very careful attention to a number of details, and it does require a will to do so, but it does not require a miracle."
Recent and rapid developments in highly efficient conversion of electrical power to light allow such a scenario now, Lubin said, when just 20 years ago it would not have been realistic to consider."
