The only room he needs is a classroom.
A 0% THD input's output is no different than one with 5% THD.
The harmonics do not increase/decrease output.
Drop across the filter may.
No different than a high Z feeder
Btw, your 200 W will not do 200 J/sec of work. e, heater, motor, etc.
There is a reason power is rated 'average' based on RMS values.
It depends on how you define rms power.You do not want to calculate the rms value of the ac power waveform. This produces a result that is not physically meaningful.You do use the rms values of voltage and/or current to calculate average power, which does produce meaningful...

How much power is dissipated when a 1 V rms sinusoidal voltage is placed across a 1 Ω resistor?
This is well understood1 and there is no controversy here.
Now, let’s see how this compares with the value from an rms power calculation.
Figure 1 shows a graph of a 1 V rms sinusoid. The peak-to-peak value is 1 V rms × 2 √2 = 2.828 V, swinging from +1.414 V to –1.414 V.2
The power dissipated by a sinusoidal 1 V rms across a 1 Ω resistor is 1 W, not 1.225 W. Thus, it is the average power that produces the correct value, and thus it is average power that has physical significance. The rms power (as defined here) has no obvious useful meaning (no obvious physical/electrical significance), other than being a quantity that can be calculated as an exercise.
It is a trivial exercise to perform the same analysis using a 1 A rms sinusoidal current through a 1 Ω resistor. The result is the same.
Power supplies for integrated circuits (ICs) are generally dc, so rms power is not an issue for IC power. For dc, average and rms are the same value as dc. The importance of using average power, as opposed to rms power as defined in this document, applies to power associated with time-varying voltage and current—that is, noise, RF signals, and oscillators.
Use rms voltage and/or rms current to calculate average power, resulting in meaningful power values.
