Caveat: Tree #126

Here is a tree from the archives.

I didn’t walk or take pictures of trees because I was digging a hole.

The hole will accommodate a pipe off the new well-head, when the well-drilling guys return to put in the pump.

The hole is difficult to dig because there are quite large rocks embedded in the gravel, which Richard put those rocks there when he was building the driveway / parking pad, where the new well is located.

Caveat: It’s a cold world

This is interesting. There’s a new thing being tested (invented): it’s called a negative illumination diode. It generates electricity in a way similar to the way a photovoltaic cell does, but instead of generating current from the incoming photons (from e.g. the sun), it generates electricity from the outgoing photons. Outgoing photons, you ask? There are always outgoing photons, on earth, because space is cold and the earth radiates heat (infrared photons) from all its surfaces, including from the diode in question. See here.
