BREAKING NEWS Trump Confirms Surprise US Airstrikes on Iran’s Nuclear Sites, Including Fordo
Yeah, that's what every leftist media outlet is claiming, and every leftist is praying for. I know you guys are all atheists, but just in case... -

According to my pulse oximeter, I should be dead :) Buy an oxygen concentrator?
Its not really that complicated... I works through whats called a Pressure Swing Adsorption Process (PSA). Ambient air is compressed and forced into one zeolite-filled tower... Nitrogen is adsorbed onto the surface of the *zeolite under pressure. (*Zeolite is a microporous, aluminosilicate mineral... its like a sponge made of crystals. It has a strong natural affinity for nitrogen due to its surface structure and electrostatic properties). The remaining Oxygen (and other trace gases I listed earlier) pass through to the reservoir. Thus, ultimately, this is a Nitrogen removal process, rather than a Oxygen concentration process. Once the zeolite-filled tower is saturated with N2, it becomes ineffective, when pressure is reduced the N2 is vented to the atmosphere... and the cycle is repeated - usually by switching between two towers. Of course, scams could exist, and for such equipment it would be difficult to trust Lazada etc... sourcing from a reputable brand and re-seller / seller is obviously key. -

Poll Should Thailand legalize brothels?
Are you living in Thailand and in a relationship with a Thai woman? If so I would class you as a sexpat. If you do not live here but when on holiday here you have sex with one or more Thai women that would make you a sex tourist. If you come on holidays with your non Thai wife or girlfriend and don’t touch the local women you are just a tourist. -

Actually, it's an interesting scientific question as to how the oxygen gas is extracted. Very basically, the gases are pushed through a membrane with tiny holes in it. Oxygen molecules are smaller than nitrogen molecules, so pass through the membrane, while the nitrogen molecules are too big to pass through 🙂 Now some clever chap will point out to me that according to the Periodic Table, nitrogen gas atoms have 7 protons, whilst oxygen have 8 - so oxygen atoms are bigger yes? Actually no, because the larger number of protons in oxygen atoms means that the atomic force pulling on the electrons (flying around the outside of the atom) is stronger than for nitrogen atoms, so the oxygen atoms are physcially smaller. Science is a wonderful subject 🙂
