Anybody else think it's funny (not necessarily surprising) that the indirect evaporative water cooling that data centers use is not available for residential use. It's the most energy efficient cooling method, albeit it uses a non-renewable resource(fresh drinking water).

Look around and you'll realize that first off, the actual method of doing this(the Maisotsenko cycle) is so heavily patented by seely international that nobody else makes it(except one company that got around the patents but they are in the same league as seely). Second, there is no residential version of it. Only industrial/commercial models. Aka computer cooling only, not for humans.

Like yea I get it, of everyone ran one of these then water shortages would become a problem. But data centers and anyone with deep enough pockets gets free reign?

There is a method of air conditioning that uses 80% less electricity, uses only water as a coolant, circulates 100% fresh air, doesn't add humidity, and can achieve dew point temperatures.

It's called the maisotsenko cycle and it's been parented to hell and back since the 1970's. Only the patent owners can make this thing, and they typically reserve it for industrial uses only.

The working principle is fresh air comes in through dry metal channels that alternate with wet channels. The channels are separated but heat can transfer through the walls of the channels. A portion of the air coming out of the dry channels is recirculated into the wet channels, which then blow back outside. This air evaporates the water in the wet channels and cools the walls. This then cools the incoming air further than ambient. Since the air evaporating the water is now cooler as well, it is not reheating the walls and the system can only get colder until there is no heat left to evaporate water(dew point).

Now here's the thing about vanlifers, we don't really give a damn about patents do we? Imagine how many lives could have been saved with this technology since its invention, where AC cost was a contributing factor. Think about all the cfcs released by residential AC systems that have warmed the planet enormously. Your car is currently leaking a refrigerant called r-134 that has 1400x the heat trapping ability as CO2 into the atmosphere.

This summer, I'm gonna make this thing and if nobody beats me to it, I'll show you all how to make it as well. This fucking technology should be illegal to patent

No sponsorships here or anything. Just my love letter to B40. It's so damn good, the nugs grind perfect every time, smoke perfect every time, and the high is really unbeatable for the price imo. I'm a pretty heavy stoner, I usually show up to work buzzed.

I cannot smoke this stuff before work, the body high and trippy mind last too long. Great stuff for after work though. B40, I love to see it. I don't know how you manage to keep this offering so cheap, but I'll smoke it until the day it's not. Seriously good stuff!
