Entangled-Light-Emitting Diode
I really want one of these. But they appear to be vapor ware???

Momentum in an Electric Circuit
I know what energy and power is in an electric circuit. It occurred to me I have not ever asked what momentum corresponds to. Research Links Momentum in a DC circuit – from Physics examples and other Pedagogical Diversions

Entangling 2 different color photons
What I think is interesting about this is that since they are 2 different frequencies it becomes much harder to blame the strange behavior of entanglement on phase coherency. Beware I could still be wrong about that. Link to Article.
