Could cryonics work? See the answer here: lettersfromprometheus.substack.com/p/why-cryonics…

The latest Letter from Prometheus is about cryonics—that people arrange for their bodies to be cooled to extremely low temperatures after death, in the hope that advances in medical science will one day make it possible to revive them.

Some drugs (acarbose, semaglutide, rapamycin) show promise, but only reducing all-cause mortality would truly prove anti-ageing effects. Read more: lettersfromprometheus.substack.com/p/can-we-stop-…

Although ageing perfectly fits the definition of a disease, it isn’t recognized as such. As long as this doesn’t change, we cannot seriously hope to fund medical research aimed at testing compounds to treat it.

@ApoStructura The huge difference between Apollo and Artemis is that while the first space race was ended with Moon landings, this one only begins with them. By building a sustained presence on the Moon, we shift humanity’s frontier from 2,000 km above Earth to 400,000 km—and then beyond.

53 years and 4 months. It’s been 53 years and 4 months since anyone went around the moon. For most people alive today (including me) that was before we were born. And today Artemis II launches to finally change that. Godspeed!

The flight of Artemis II will mark the first time since 1972 that humans leave Earth’s immediate neighbourhood: apart from the astronauts of the Apollo programme—just 24 people—no one has ever travelled far enough to see the planet as a whole.

From the 1890s to 1950s, sewer systems, vaccines, and antibiotics raised life expectancy by 3–4 years per decade. Since then, gains have slowed significantly—because we now fight not external pathogens, but chronic and degenerative diseases caused by ageing.

The leading cause of death isn’t heart disease, cancer, or neurodegeneration—it is ageing. If the probability of death from natural causes remained constant throughout adulthood—if we eliminated the effects of ageing—life expectancy could be several thousand years.

How much CO₂ can we save through lifestyle choices? driving an EV instead of an ICE car for a year –> 1.5–2.6 tonnes a family vacation by car instead of flying –> 1.3–1.7 tonnes using a heat pump instead of gas heating (annually) –> 1.1–2.3 tonnes Everything else pales in comparison. See the calculations at lettersfromprometheus.substack.com/p/three-and-a-…

Compared to a gas vehicle, manufacturing an EV produces an additional 5–8 tonnes of CO₂-equivalent emissions due to the battery. Depending on the electricity mix, this carbon debt is offset after 25,000 to 60,000 kilometres. See the detailed calculations at lettersfromprometheus.substack.com/p/three-and-a-…

The key to curbing global warming is a rapid large-scale shift to clean energy (nuclear & renewables). When it comes to individual action, three choices have the greatest impact: an EV over a gas car; taking the train or driving instead of flying; heat pumps instead of gas boilers.

Just as coal replaced wood as the primary energy source in the 19th century, so are nuclear and solar energy replacing fossil fuels today.

We made a similar report a year ago, covering: - nuclear reactors, - batteries, - rockets and spacecraft, - semiconductor manufacturing, - chip design, - AI, - quantum computing, - humanoid robots, and - brain–computer interfaces. It's downloadable from here: prometheusztarsasag.hu/mapofthefuture

I’m building a website to track top companies in industries like nuclear fusion, rockets, autonomous vehicles etc. Will release soon!

Critics of electrification often cite energy return on investment (EROI) calculations to argue that the transition will lead to energy scarcity. Their math is wrong: replacing fossil-fuel electricity with a mix of renewables and nuclear power does not reduce EROI—it actually increases it.

Three reasons for climate optimism: 1) The technology already exists—we need scale and momentum, not breakthroughs. 2) Progress is real—the data shows we’re moving in the right direction. 3) Humanity has repeatedly shown that it can adapt quickly and efficiently when necessary.

In Hungary, while nuclear power has consistently provided around 40% of electricity generation, solar’s share rose from 2% to 24% in just six years.

Per-capita carbon-dioxide emissions have been declining for at least fifteen years in wealthy countries even as their economies have continued to grow—showing that decoupling emissions from growth is not only possible, but already underway.

There is hardly a difference between the science rejectionism of climate doomers and climate change deniers. In Deep Adaptation, J. Bendell devotes just as much energy to questioning the credibility of the IPCC as any hardcore climate denier would.

No doubt degrowth is unique—there is no other political ideology that explicitly promises to lead to impoverishment. Yet there is nothing new or untested about it—just study the history of North Korea or East Germany.
