Sabine Hossenfelder reads a confidential email and uses it to explain her worries about academia and incentives in theoretical physics research. She ties it to her earlier Nature Physics comment on research quality.

Thunderf00t critiques the MIT and Berkeley metal-organic framework device that claims to pull water from air using only solar heating. He argues the energy accounting does not work and that such devices are essentially fancy dehumidifiers.

A video debunking popular primitive-building YouTube channels, arguing that their digging, concrete and construction are staged. It uses the Primitive Technology channel as a baseline for what is plausible in a natural setting.

A Thunderf00t video debunking Energy Vault, a gravity-based energy storage scheme that stacks concrete blocks with cranes. He argues it is impractical and compares it to pseudoscience.
