You’re not wrong, but I think your point is missing the most interesting aspect of the article. Which is fair, I don’t think this article was written very well. The thing that stands out to me the most is the realization that mycelial networks generate electricity at all, just from applied pressure.

The article stated that this is the piezoelectric effect, which by definition is a very minuscule amount of electricity. I can’t imagine anyone is seriously considering this effect could be tapped reduce carbon emissions. They suggested if more buildings were constructed from wood that might reduce carbon, but it’s sort of a tangent to what should have been the headliner if you ask me :)

The fact that the fungus is generating an electric charge, albeit very small seems incredible to me! Add it to the list of incredible things fungus and mushrooms are capable of, and the important role they play in our environment. Is no surprise the show ‘Star Trek Discovery’ chose a ‘mycelial network’ as the ships basis for teleporting around the universe.
