The piezoelectric effect
of tears, this we must not neglect.
For the climate change cries
that bring tears to their eyes,
is power that powers their sect.

From the UNIVERSITY OF LIMERICK and the “now if we can just keep people wailing about climate change we’ll have sustainable energy” department. Reports are that “weepy Bill McKibben” will be the first large scale electric tears generation facility. Eric Holthaus will be in the control group:

Irish scientists can now produce electricity from tears
A team of Irish scientists has discovered that applying pressure to a protein found in egg whites and tears can generate electricity. The researchers from the Bernal Institute, University of Limerick (UL), Ireland, observed that crystals of lysozyme, a model protein that is abundant in egg whites of birds as well as in the tears, saliva and milk of mammals can generate electricity when pressed. Their report is published today (October 2) in the journal, Applied Physics Letters.
The amount of electricity generated is negligible, but the emotional tension generated can produce strong emotional power.
