Tom Scott visits Onkalo in Finland, the planned deep geologic repository for high-level nuclear waste intended to be sealed for 100,000 years.

Technology Connections explains how a home can act as a thermal battery by pre-cooling or pre-heating when electricity is cheap or abundant. He shows how this shifts load off-peak and eases strain on the grid.

Marshall Kirk McKusick gives a talk at EuroBSDCon tracing filesystem and storage development from 1979 to today, using the BSD Fast Filesystem as the focus. It covers early disk-geometry optimization through later contiguous layout and small-file performance work.

Stanford futurist Tony Seba argues that electric vehicles, battery storage, solar and autonomous vehicles form a 10x exponential disruption that will make fossil fuels obsolete within about a decade. It draws on his Clean Disruption book.

Randall Munroe of xkcd answers what would happen if you swam in a spent nuclear fuel pool, and how much radiation you would receive at the surface versus at depth.

Kurzgesagt asks whether advanced civilizations could have existed on Earth in the deep past and left little evidence. It looks at time as a dimension for searching for alien civilizations and the limits of the geological record.

Allan Jude of Klara presents work on making ZFS scale on fast NVMe storage, covering fixes to the TaskQueue interface and removal of bottlenecks. The talk was given at EuroBSDcon 2022 and describes raising write throughput from about 3 to over 7 GB/sec.
