water engineering

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.

Thunderf00t debunks the Waterseer, a crowdfunded device that claims to condense drinking water from the air using cool ground. He argues the physics does not support its claims.

Thunderf00t debunks the Fontus self-filling water bottle, arguing that pulling meaningful amounts of water from air with a small solar-powered device is thermodynamically impractical.

Thunderf00t argues that Zero Mass Water's solar-powered atmospheric water generator is essentially a dehumidifier with solar panels. He critiques its economics and physics, especially in arid places.

Louis Rossmann, a Macbook repair shop owner, goes through a long list of Apple hardware engineering failures, from GPU defects to keyboards and repair practices.

Linus Tech Tips argues that big air coolers beat AIO liquid coolers for most PCs. They compare quietness and temperatures, using the Noctua NH-U12A as the example.

A short, humorous critique of Helion Energy's fusion approach, framed as a response to a Real Engineering video. It covers low reactivity, neutron production, bremsstrahlung losses and diagnostics.

Thunderf00t, a physicist, critically assesses the Hyperloop concept, covering the vacuum, pressure, safety, and cost problems of high-speed tube travel. He argues the media accepted the claims uncritically.

AvE tears down a broken Dyson Animal vacuum and its expensive replacement, criticizing the molded plastic, flimsy switches and overall engineering, with his usual profane commentary.

h3h3Productions describes how a hacker took over their phone number by getting a SIM card from T-Mobile, and gives security advice such as using a hardware key and an authenticator app.

Scam-baiter Jim Browning explains how he fell for a phishing email and ended up deleting his own YouTube channel. He walks through the circumstances and prior incidents that made the scam convincing.

John Oliver's Last Week Tonight segment on Boeing, tracing how it went from a quality engineering company to one tied to crashes and 'quality escapes'. It covers the 737 MAX failures and employee concerns about safety.

William Osman describes helping build parts of the MrBeast Squid Game event, including hacking together hundreds of wifi-controlled blood packs in about three weeks. He covers the chaos and near-failures along the way.

Thunderf00t critiques SpinLaunch, the startup that proposes flinging payloads to space with a giant centrifuge. He argues the physics and engineering do not hold up.

Dave Jones of EEVblog debunks the uBeam ultrasonic wireless phone charging technology and explains why it is not practical. He covers efficiency, coupling loss and safety, and responds to the founder's remarks about engineers.

Adam Something argues that the Hyperloop is impractical, covering the costs and engineering problems of running trains in a near vacuum compared with conventional rail and metros. The description admits some wrong numbers in the original cut.
