- lstodd 1mo agoEnergy efficiency is secondary, that can be mitigated by solar power plus some thermal mass inside. That is actually most efficient use of solar from my pow. Their bane is hydrogen partial pressure dropping due to it leaking through the metal of the tubes. That .. is problematic. OTOH it'll last for like 20 years before you'd need to replenish.

- tingletech 1mo agoin the US you can still buy hydrogen/ammonia/water gas absorption refrigerators such as "EZ Freeze". Propane/Natural Gas refrigerators use this cycle. I'm sure you can get them all over the world, the cycle is older than the one in the article.
