Let me explain:&lt;p&gt;what we want isn&amp;#x27;t to generate electricity through bacteria that digests wastewater -- what we want is to feed electricity to the bacteria that digests wastewater, just to enable that bacteria to do it better, faster, and &amp;quot;wider&amp;quot;.&lt;p&gt;Let&amp;#x27;s imagine I have a septic tank behind the house. I don&amp;#x27;t need to find out how I can run a LED light from the bacteria in the tank. What I want is to plug that biosystem to electrical power, so that the septic tank biorection is 100x speeded up, in a 10x smaller tank. Even if it uses up a few Watts of power.&lt;p&gt;And, once we do that, think of the possibilities that open up: once you feed power into the biosystem, it becomes energetically possible to drive bioreactions in the opposite direction from the energy gradient, basically driving the reaction &amp;quot;up the hill&amp;quot; with electrical power. Now that&amp;#x27;s something!</text></comment>

Or perhaps it is only of chemical interest?&lt;p&gt;[1] &lt;a href=&quot;https:&amp;#x2F;&amp;#x2F;www.cell.com&amp;#x2F;cms&amp;#x2F;10.1016&amp;#x2F;j.joule.2023.08.006&amp;#x2F;attachment&amp;#x2F;517b3268-378a-494e-a5c6-020a6aebcb29&amp;#x2F;mmc1.pdf&quot; rel=&quot;nofollow noreferrer&quot;&gt;https:&amp;#x2F;&amp;#x2F;www.cell.com&amp;#x2F;cms&amp;#x2F;10.1016&amp;#x2F;j.joule.2023.08.006&amp;#x2F;attachm...&lt;/a&gt;
