Comment Re:Bad idea if only for long term maintenance (Score 2) 88

I deal with UPS's as well. Not really the same thing as the utility batteries. UPS's have not changed much in decades. Most of them still use lead acid batteries. They don't last very long even when maintained. When looking at the cost, size, weight, maintenance and reliability I have to question why we keep doing it the same way with UPS's.

Comment Plenty of drives are used in audio without problem (Score 1) 72

We have used spinning hard-drives in audio for decades now in both studio and live production. Studios would not typically expose the drives to continuous levels over 91dB, but it is not uncommon. Live production you can over 105dB for many hours and I have never heard of anyone have vibration issues.

Heating elements don't care if they are AC or DC. It is pretty common to use them as dump loads. But getting the voltage to run yours off battery banks for homes is not realistic. 48 volts would be lucky to warm the water a few degrees. Utility type banks could run it no problem. You reminded me why I ended up with natural gas for our instant water heater. I about choked when I figured I needed 55kW just for the water heater.
