I wasn't aware he'd proposed this, else I'd have said triangular light
bulbs have existed for decades. Printed (screen or inkjet)
electroluminescent lamps have been produced and in use since I was a
little tyke. Google up "Luminescent Systems, Inc."....
If he was talking about a tetrahedral light bulb, I'd have to say that
such a bulb would actually be producable, though not generally as
structurally strong as a round bulb at all points.
