Climate Town argues for moving away from gas stoves. It covers the gas industry's decades of marketing and lobbying, health effects of gas cooking, methane leaks, and the case for induction.

Casey Muratori shows how typical 'clean code' object-oriented patterns can cost large factors in performance. He benchmarks them against simpler data-oriented code.

Aging Wheels compares a road trip in a Polestar 2 with an identical drive in a Tesla, showing the charging problems of non-Tesla EVs. It argues that outside Tesla's network, EV road trips have become frustrating.

Casey Muratori responds on-stream to a dismissive Twitter post by demonstrating how slow Visual Studio's startup and debugger watch window are, comparing it to much older software and machines. It is a long rant about software performance and bloat.

A short clip of Casey Muratori from Handmade Hero explaining why he rejects the object-oriented mindset and how to move away from it. It is part rant, part programming philosophy.

Yanis Varoufakis argues that Europe's electricity price spikes stem from how the energy market was designed and privatised, plus corporate profiteering. He proposes ways out.

2kliksphilip examines UserBenchmark, a hardware comparison site known for strongly biased, pro-Intel writing. The video explains the site's credibility problems and points viewers to better sources for CPU and GPU information.

John Oliver's Last Week Tonight segment on the state of the US power grid, why it needs fixing, and the risks of aging infrastructure.

A UK tradesman's rant on the disadvantages of air source heat pumps, covering grants, heat pump types and whether they are worth it. He argues they are impractical for many British homes.

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.

Adam Something argues in four minutes that gravity batteries like Energy Vault, which lift concrete blocks with cranes, are a poor energy storage idea. He draws on a longer Thunderf00t debunk.

EEVblog's Dave Jones critiques Reflect Orbital's plan to sell sunlight to solar farms after dark using orbital mirrors. He walks through the numbers to show the idea does not work out.

Dave Jones of EEVblog debunks the marketing claims of the self-charging nano nuclear diamond battery from NDB Inc. He argues it is no better than existing 100uW betavoltaic batteries, with an added graphene supercapacitor.

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.

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.
