In Outer Space without a Space Suit?

TL;DR

This paper explores a novel concept of enabling humans to survive and function in outer space without traditional space suits by developing a system to manage oxygen and carbon dioxide levels, with potential applications on Earth.

Contribution

It proposes a new system for human respiration in space without a space suit, addressing oxygen supply and carbon dioxide removal, expanding possibilities for space colonization and hazardous environments.

Findings

Conceptual system for space without a suit

Potential for long-term human activity in space

Applications in hazardous Earth environments

Abstract

The author proposes and investigates his old idea - a living human in space without the encumbrance of a complex space suit. Only in this condition can biological humanity seriously attempt to colonize space because all planets of Solar system (except the Earth) do not have suitable atmospheres. Aside from the issue of temperature, a suitable partial pressure of oxygen is lacking. In this case the main problem is how to satiate human blood with oxygen and delete carbonic acid gas (carbon dioxide). The proposed system would enable a person to function in outer space without a space suit and, for a long time, without food. That is useful also in the Earth for sustaining working men in an otherwise deadly atmosphere laden with lethal particulates (in case of nuclear, chemical or biological war), in underground confined spaces without fresh air, under water or a top high mountains above a height that can sustain respiration.
