Regardless of what the future environment looks like, there will be one, and civil engineering projects will need to interact with it.
The civil and environmental program seems like it opens the door that you're interested in now without locking you behind it.
Just for scale:
A single piezo element produces voltage of a few milli-Volts and power of a few milli-Watts.
If we assume 5 mV, then you'd need a thousand elements in series to get a 5 Volt input to the rectifier.
Those thousand elements might generate a Watt.
So, 10 strings of a thousand...
That little controller looks like it would do the job, but I'd want the manual to understand how it drives the SSR in PID mode.
Or, you could buy a heater with a controller already included. https://www.mrclab.com/digital-immersion-heaters-up-to-100300c
