I'm making a note here:

huge success

She was swimming at North Fremantle (Fremantle is where the Swan River reaches the ocean). That area gets little rainfall in summer, so that section of the river is likely not much different from seawater.

Russia's next move might be: "buy our gas, or else we'll vent it and make climate change worse!"

In practical terms, introducing fresh air means that the OvenU needs to heat it (requiring energy). You'd also need a definite exhaust path for the (quite hot) air. For a standalone cooker, that would heat the kitchen in short order. For these two reasons it makes sense that they'd be a closed systen.

Hmm, to get rid of the inductive losses we could use a direct wire connection. There's a lot of power involved so having it next to the road might be dangerous... So, we'll put it above the vehicle. We'll need a return path for the electricity, so let's have a metal bar under the vehicle for that. Self-driving is difficult, so seeing as we have something in the road already, let's ensured that it's accurately placed for the vehicles to follow it. Maybe even make it a mechanical connection. Aaannd... We've reinvented electric trams/trains.

Ah, that would explain the orange on the Mitre 10 store (they tend to be blue in Aus).
