You said you dropped it and now this happens.

That tells me something is broken not something is dirty.

Maybe broken hinge or bent casing preventing movement.

Just in my mechanics opinion.

I would spend my year trying to turn my side business into my actual business then I couldn’t quite my job and work for myself doing what I do now but for more money

My wife and I are 30 and we’re just doing out first round of IVF now. It’s bloody expensive in Australia we can’t really afford many rounds so it’s going to be interesting. Spending house savings on having a child was never something I thought we would be doing

Fucking Boris web was my favourite movie as a kid

Oh I feel things but satisfactory instead

He looks damn old, you Americans love your old pollies but

Thanks I’ll check out the videos.

Shoes i can’t do much about given i wear work boots 13 hours a day but luckily today it’s improved with some stretching and taking it easy

Playing football in Australia. The Australian version AFL we are the best at it

Sabacc? Starwars Sabacc? With interference fields etc?

As a computer game?

Or a real physical card game

Yeah that’s the plan when I can actually get to a Dr/physio. At the moment I’ve been getting by doing stretches a couple times a day.

That would be interesting, although make-up would skew results.

Tinder being a great example of that

It appears i have upset my hip/ lower back and if I love wrong it refers pain into my knee and I can’t bend it without laying down on my back and doing a minute of stretches to get it right again.

Then it’s good for an hour or two before it happens again.

Fortunately I’m an Australian and can go to a dr and physio. Unfortunately I’m in PNG for work for 3 more weeks with none of that available

Wait no, Michael

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.
