energy saving

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.

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.

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.

Sabine Hossenfelder weighs the arguments for and against nuclear power, covering waste, fuel supply and newer reactor designs. She is skeptical that fast breeders and thorium solve the problems.

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.

Adam Something gives a short, sarcastic argument that carbon capture does not live up to its promises. He says the energy it uses would be better spent replacing fossil sources directly.

A Last Week Tonight segment on retirement plans, high fees and bad financial advice, with comedic sketches. It explains how fees eat into retirement savings and favors low-cost passive investing.

A former fusion scientist argues why fusion power by 2040 is unrealistic, covering the physics challenges, neutron issues and optimistic company claims, with a brief note of good news.

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.

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.
