Prototypes essential. From the images so far, NSW not quite reaching the design level of Knutsford Freo, which integrates roads and streetscape. If we’re going to dream, let’s dream big.

To control pathogens effectively, the evidence seems to suggest <700 ppm. This implies 10-14 litres per second per person. You may be familiar with this paper by Rudnick and Milton graphing R for different pathogens against CO2 levels.

A spec house from 2025 left and one from 1965, right. The economists in the Productivity Commission think these two houses are the same, and that the reason costs have gone up is that workers are lazy. They are idiots.

I’ll be flying the Thrive banner at EduTech in Sydney this morning. I’m talking about why schools should be mechanically ventilated.

What a desperate moron. Who does he think he’s fooling? If Congress does not remove him for being unfit, then there is no point in giving Congress the power. Surely there are some adults left in the Republican Party?

What fake Nazi stuff? It looked pretty real to me. Also, Elon seems to have done an excellent job of destroying his own credibility, regardless of any outside help. A person rejoicing at putting USAID into the “wood-chipper” and sacking 1,000’s of workers without reason seems evil to me.
