Could someone knowledgeable explain why fiber optics could or could not be used for power transmission large or small?

The formula for power in optical fiber is shown below. X is photons per second, lambda is wavelength, light speed is c (speed of light is reduced significantly in fiber ~30% reduction from vacuum speed), h term is Planck constant.

power equation

Therefore we are transmitting power, but is there a converter out there to take this power and make it useful to electrical systems? How would one convert the light power to power useful to electronics? This would probably be just supplying a voltage to a circuit of resistance R.
