Yeah, but that's just a gas explosion. Boilers are heavy pressure vessels. The burner could blow out and cause an explosion destroying the building, leaving the boiler tank sitting on its stand (less some insulation). Boiler explosions are a whole different thing - a (typically structurally-compromised) tank explodes due to reaching its pressure limit.

The weather-cam footage looked a bit flamey. I don't think it was steam.

Spread it over their lawn. The solution to pollution is dilution, right?

> high thermal energy increases the average energy of all collisions.

I was thinking that thermal-kinetic energy of a given atom could add, subtract or have no effect on the total impact energy depending on the atom and neutron's direction at the moment of impact. Within a medium, the kinetic direction of a given particle due to thermal effects would be chaotic, so effectively random.

> sum of kinetic energy of all the moving massive particles in a given region

So, high thermal energy might increase the energy of one collision, but reduce that of another. Net zero?

Does thermal energy play a role? As in, is a U235 in reactor-like conditions less likely to fuse from a neutron strike of X energy, versus a U235 in the plasma cloud of a thermonuclear device?

Based purely on the labeling and hole spacing, they're giving you 3 terminal strips, plus one for ground.

The reason for the strips is that combining stranded wire and solid wire in a single connector (whether screw-type or wire nut) can be precarious. The solid wire can provide much more mechanical support, making the connection feel tight while the stranded wire can still slip out or is poorly connected.

Back to the fixture plate, under "FLEX N" you have 3 ports ganged together. This should be the neutral/return wire of your lighting circuit/loop - the wire returning to your breaker (or previous light fixture), a wire returning from the next light fixture, and the neutral/return of your light.

Next is "LOOP IN" with 3 ports that should be connected to each other but not the first 3 "N" ports. This is the hot/supply/live/line wire of your lighting circuit. The 3 ports should be: power supplied from your breaker, power out to your next fixture, and constant power out to your light switch.

The final 2 "FLEX L" ports (again, connected to each other but none of the previous 6 ports) should be switched hot/line returning from the wall switch, and the light fixture's hot/line wire.

All together, the strip accepts the power connections from the breaker or previous light fixture on the circuit/loop (2 solid wires), the next fixture on the circuit/loop (2 solid wires), the wires to the wall switch (2 solid wires), and the wires to the light fixture (2 stranded wires).

An observation: the left-most red wire on the terminal strip looks like it gets skinny a cm or two from the strip. It could just be bending behind the black wire (which has a speck of white paint or something on it), or the wire could be broken inside the insulation. If it's skinny, give it a wiggle and see if it bends easily at the thin spot.

Correct. The virus needs time to multiply before it will show up on an antigen test. ART tests are a reasonable gauge of how infectious you are. If you were exposed mere hours before, you are not yet infectious and so will not register as infected. An exception being if you were just exposed to a massive dose of the virus, such that there is a substantial amount of the virus trapped in the mucous in your nose.

It sounds to me like they're suggesting grid-connection management devices (such as an inverter for a solar power installation) should all have a simple ad-hoc mode so that local grids can be patched together when faced with major infrastructure damage. It's not a replacement for organized infrastructure, but a minimalist system that can still load-manage when your infrastructure consists of nothing but extension cords.
