The normal air around you weighs about 1.3 kilos per cubic metre of air.
This air consists mainly of nitrogen, weight about 75.5%, oxygen 23.1% and argon 1.3%.
The air also consists of 20 or so other substances that account for less than 1% of the weight, eight of which are so-called trace gases such as methane and hydrogen.
On the other hand, there are actually vast amounts of air.
The smallest/lightest gases in the air are hydrogen (H2) with a molecular weight of about 2, helium (HE) with an atomic weight of about 4 and methane (CH4) with a molecular weight of about 16. These are the smallest molecules, the ones that have to be filtered out.
HyMeAir is of course unable to guarantee the level of efficiency when Nano Towers are used to separate the methane and hydrogen molecules from normal air when the wind blows. As in all technical development, efficiency will gradually increase. To be sure HyMeAir has estimated the efficiency at a low level of 33–50%.
The atmosphere consists mainly of nitrogen, oxygen and argon, all of which are much heavier and larger molecules/atoms than hydrogen and methane.
The fact that gases and substances in the air are relatively well mixed is primarily because the wind is always blowing. And to some extent because atoms and molecules collide with one another, and also because of the earth’s constant supply of hydrogen and methane.
Hydrogen and methane molecules are so small and light that they gradually rise and disappear out of the atmosphere. In other words, hydrogen and methane are separated continuously from the other, bigger molecules/atoms, heavier gases and substances in the air. It is this separation effect that Nano Towers make use of via the force of the wind.
Methane that remains in the atmosphere only stays in the earth’s atmosphere for eight years, as methane that is released on the earth’s surface is gradually converted into carbon dioxide and water in the atmosphere.
Hydrogen and methane are very rich in energy and easy to use as fuel. If we filter these energy gases out of the wind instead of letting them disappear up into the atmosphere and dissolve, we can meet the entire world’s energy needs.
With an adapted nano filter, you can exclude all of the fifteen or so other “large” substances and gases in the air, the substances that are of no interest. A Nano Tower could be built, for example, so that the first filter only lets through methane, helium and hydrogen. The next filter does not let methane through, and this is held in a methane container. The next filter system only lets helium and hydrogen through, with the helium being held in a helium container. The third filter only lets the hydrogen through, which is held in a hydrogen container.
You could also build Nano Towers that only capture, for example, methane and/or hydrogen, there are many variations.
You can of course also make it easy by filtering out all of the three light, small molecular and atomic gases methane, helium and hydrogen via one single filter system, and then incinerating the methane and hydrogen together with the helium with no separation. Helium does not burn.
Helium is currently used in a number of technical applications and in balloons. Helium is much lighter than the air mixture. There is something of a shortage of helium, which currently costs USD 5–10 per cubic metre.
