In 2019, a precise 3D capture of a building cost more than £30,000. Today it costs under £500, and a phone walkthrough gets you most of the way there. Yet the knowledge that runs factories, warehouses and data centres still lives in photos, PDFs, spreadsheets and the heads of the people who walk the floor.

Aeration (pumping air into tanks so bacteria can break down waste) accounts for around 30% of a wastewater treatment plant's operating cost. Because operators can't see the biology in real time, most over-aerate by 20–30% as a safety buffer. Globally, aeration consumes roughly 1.5% of all energy demand, around $42bn a year. A 15% optimisation would be worth $6.3bn annually.

There is a quiet financial crisis happening in millions of UK households, and it repeats itself every month with very little fanfare. A nursery invoice arrives. It asks for £1,000, £1,500, sometimes £2,000 in full, in advance, before the month has even started. And parents, with very few options, find a way to pay it. Or they don't.
