I like the one for Venus. I’d like to try that myself, especially the challenge of making a shrink-wrap heatproof wetsuit.

Makes me consider how close to the conditions on Venus could humans survive with just cyber-enhanced breathing. Body cooling would be primarily by breathing ice-cold air-or-liquid-fluorocarbon. Add plenty of moisture in that air to keep the body hydrated. Cyber enhance the breathing in and out to reduce stain on the lungs due to breathing liquid or a very dense gas mixture.

Evaporation from all skin surfaces keep skin cool. Appropriate pain-killing and other drugs.

It would also be interesting to figure out how much of bodily nutrition could be absorbed through the lungs rather than through the stomach.

It’s not such a silly idea “Today, there are more than 65 different inhaled products of more than 20 active ingredients”. But inhaled products tend to be measured in micrograms or milligrams, not the grams to kg needed for nutrition, eg sugar water plus vitamins and minerals. But is this a really hard and fast limit on mass uptake? Feeding via the lungs, particularly at ultra-high pulmonary pressures such as those on Venus, may be a possibility.

It seems worth investigating, anyway.

No comments?

So it’s up to me to design an environmental suit capable of protecting a human from the environment of Venus?
