I just had to argue with my laptop because it caught covid i mean copilot the other day.

Its abundance of sunlight and heavy investment in solar cell technology has positioned Saudi Arabia well in its transition to becoming a leading exporter of renewable energy. Indeed, solar energy currently makes up more than 80% of the Kingdom’s green energy capacity. However, these cells bring a twisted irony, as their operation exposes them to overheating risks. Cooling systems are therefore necessary, but many depend on electricity.

An international research team led by KAUST Professor Qiaoqiang Gan has designed a potential solution. Their device needs no electricity, as it extracts water from the air using nothing more than gravity and relies on cheap, readily available materials.

Along with keeping the solar cells and other semiconductor technologies cool, the water can be repurposed for irrigation, washing, cooling buildings on which the solar cells are placed, and other applications.

Scientists estimate that the atmosphere contains six times more water than all the fresh water in the rivers combined. “This water can be collected by atmospheric water harvesting technologies,” says Gan.

While these technologies work reasonably well, in arid environments like that of Saudi Arabia they require electricity to harvest practical amounts of water. This demand risks deterring the adoption of solar cells in rural regions of the Kingdom, where electricity infrastructure is costly.

One reason for the low efficiency is that the water adheres to the surface of the harvesting device. Professor Dan Daniel and Shakeel Ahmad, a postdoc in Gan’s group, found that by adding a lubricant coating that is a mix of a commercial polymer and silicon oil, they could collect more water by relying on only gravity.

“A common challenge in atmospheric water harvesting systems is that water droplets tend to remain pinned to the surface [of the device], necessitating active condensate collection. Our coating effectively eliminated pinning, enabling true passive water collection driven by water,” says Ahmad. “Since this system operates entirely on passive radiative cooling, it doesn’t consume any electricity.”

The solution is based on previous technology made by Gan, which he describes as “vertical double-sided architecture.” That system was originally designed to reflect thermal heat back to the sky to keep the solar cells cool but not to capture the water produced.

The new device was tested six times over the span of a year in natural conditions in the town of Thuwal, about 100 km north of Jeddah, and could almost double the rate of water collection compared with alternative atmospheric water harvesting technologies.

Along with Gan and Daniel, KAUST Associate Professor Gyorgy Szekely contributed to the study, which was published in Advanced Materials.

Along with the efficiency of the water collection, Daniel is equally excited about the economic benefits of adoption.

“The system doesn’t consume any electricity, leading to energy savings. Moreover, it doesn’t rely on any mechanical parts like compressors or fans, reducing the maintenance over traditional systems, leading to further savings,” he said.

If you can get it into the log and then underground. It’s all pointless though unless we fix the problem at the source…

We need to blow up the sun

Yeah fucking MSFS2020 was such a bust for me living in Australia. It took days to download then I finally got it working something went wrong with install files and had to dick around. In the end I played 3 hours of it but have hundreds in download time.

Fuck MSFS

The article says non toxic

Right, not once have I fixated on something by choice.

You think I want to be googling and playing pokemon go at work home and in bed for the past 3 weeks despite only playing it for a week 8 years ago?

Just once I want the fixation on house work or something like the gym

If you flew frequently you would understand

So once or twice a year?

I’m talking monthly or every couple weeks

Where are you flying that you’re doing 14 hours frequently?

Do line up window middle isle front to back.

Don’t dick about in the aisle

Do sit down and stay seated

Don’t recline seat ever. You’re just fucking up the person behind you

Do leave both middle arm rests free for the poor bastard sitting there

Don’t leave the window shade open if the sun’s beating in.

Best game of the bunch

Hahaha that’s right in my feels and I’m not in this thread

Cause they all learnt from the same book of lies

Ocarina of time, 3d, lock on, one enemy attacks at a time. So much of modern gaming pulled from ocarina of time

Australia is a large country but we have very little usable land. Our population is tiny too

Gabe Newell put it well.

The easiest way to stop piracy is not by putting antipiracy technology to work. It’s by giving those people a service that’s better than what they’re receiving from the pirates.

I don’t know if this worked

Let’s see
