We know that the vast majority of our planet is water. Not just that, the vast majority of our body is also water. Fitness enthusiasts would know that we lose water weight first when we finally decide to pay attention to it. Don’t fact check me on that.
When we are out on a road trip and we get stuck in a seemingly endless traffic jam lasting for hours in the middle of nowhere, we do wonder if we are going to run out of drinking water or not. All of us have heard about how difficult it is to provide safe drinking water to people living in remote locations. Is it because fresh drinking water from melting glaciers needs to be transported all the way to the middle of a desert or a mountain or a village or a dense jungle? Perhaps so. Transportation might be difficult and expensive.
Now let me ask you another question. Which location on earth is more remote than the international space station? None. Even the most inhospitable location on Earth would be less remote than space. So that brings us to the next logical question, how is drinking water transported to the astronauts living inside the international space station? The answer is, it is not. Transporting drinking water is expensive and water, before consumption, would also occupy a lot of space inside the space station, where space ironically is not available. Then how do astronauts survive without water? Do they save water and drink beer? Hahahaha. Please laugh.
The answer is so simple that I am forced to wonder why it has not been widely implemented on earth. Drinking water on the international space station is obtained from waste water treatment. Sweat and other bodily fluids are treated and converted into safe drinking water, which is happily consumed by the astronauts. Happily. This might resemble the dystopian future depicted in Dune but it actually is the utopian reality lived willingly by astronauts. What can be more Utopian than human beings having established a presence in space. So if astronauts can survive on drinking water obtained by treating waste water, why is drinking water sold in plastic bottles on earth? I believe the answer is because it is possible and people find the idea of drinking waste water, even after rigorous treatment, disgusting. When we run out of readily available drinking water on earth, we perhaps will be forced to use the technology that is currently used on the space station.
To be fair, I have seen a YouTube video where Bill Gates was promoting this technology in order to provide safe drinking water to people, who do not have access to it. I hope mass adoption of this technology does occur and economies of scale render it virtually free to every citizen of the world. What is an economy of scale, you ask? That is the topic for a different blog, but in one line, when a company sells something in massive volume, the cost of an individual item can become less without hampering the profit margin of the company selling it. At the very least, I do look forward to the day when drinking tap water is considered safe everywhere in the world including everywhere in India.
