Industrial Foregoing Version:
3.2.5 according to my mods screen

When using the Biofuel Generator, it never loses power... goes to full power and stops...
appears to function like an infinite power source

I used a bioreactor to fill it with the bio fuel until power reached Max Value
then I removed the boo reactor to make sure nothing else was still powering it

I attached an RF Tools builder to it to see if I could drain it....
RF tool Builder would only fill at 10k per tick...and it can power much faster than that
and biofuel generator never went down in power or biofuel

What is your titanium version?
