comment What happens to solar cells in water (or in anything other than air)?
@EricCzech This might not be what you were wondering about, but some of the light will be shifted in wavelength due to vibrational Raman scattering. It would require a thick layer of water to get significant Raman scattering though, and some scattered light not reaching the solar cell at all would probably have a larger effect on the efficiency than the wavelength shifts.

comment The graph of Alternating current
Probably a combination of the fact that sinusoidal AC was easier to generate when AC was invented and widely adapted and that square waves has a bunch of drawbacks. What made you think it would be immediate?

comment The graph of Alternating current
That would be a square wave. But the most common form of alternating current (the one used in power grids) is indeed sinusoidal.

comment How to weigh your nephew
The obvious method is of course to divide your nephew into small enough pieces that you can weigh each of them on the 5 kg scale and then sum the weights. Due to health reasons, I normally wouldn't recommend this method, but maybe it's ok since you mention that you're not attached to him.

comment Latent heat of vaporization at non-boiling temperature
@LDC3 Determining LHV for water evaporating is not more difficult than when it's boiling. It is simply a function of temperature (and of pressure).
