Rule 4- No self promotion or upvote-farming of any kind.

That's it.



Rule 5- No baiting or sealioning or promoting an agenda.

Just spent one month traveling around Namibia. It's an incredible country and really well set up for 4*4 camping. The landscapes are huge, sunsets are amazing, it's cheap, friendly and just so photogenic. HMU if you want more info.

[–] Ledericas@lemm.ee 9 points 23 hours ago (1 children)

were you able to see wild welwistchia plants.

[–] mrmule@sh.itjust.works 9 points 22 hours ago

Yes I was, near Swakopmund, they are also the national plant of Namibia

[–] Kolanaki@pawb.social 87 points 1 day ago (2 children)

What? No parasol over the table?

This rest stop sucks.

[–] ryannathans@aussie.zone 32 points 1 day ago (2 children)

Or the fridge?? How hard is that heat pump working

[–] SARGE@startrek.website 40 points 1 day ago

I mean, that thing is working so hard it turned the entire surrounding countryside into desert!

[–] Xerxos@lemmy.ml 6 points 19 hours ago (2 children)

Yeah, put the fridge in the shade of a solar panel. I don't believe it would work well otherwise

[–] prettybunnys@sh.itjust.works 0 points 7 hours ago

The pink fridge is a shell with a fridge inside it.

The fridge is inside an insulated box that blocks the sun.

[–] elbarto777@lemmy.world 5 points 16 hours ago

I don’t believe it would work well otherwise

What a weird comment to say about a device that's actually working well.

[–] undefined@lemmy.hogru.ch 4 points 1 day ago* (last edited 1 day ago) (2 children)

What the fuck is a parasol?

Edit: I looked it up and now I understand. Does the word happen to come from Spanish? Parasol would mean “for the sun” much like other words like parabrisas.

[–] starlinguk@lemmy.world 6 points 18 hours ago

Where are you from that you don't know what a parasol is?

[–] Thadden@lemmy.world 25 points 1 day ago (1 children)

Yes, but "para" also means "stop". Comes from "parar", "to stop". In this case it would mean something like "sun stopper". Or in your example, "breeze stopper".

[–] undefined@lemmy.hogru.ch 10 points 1 day ago (1 children)

Oh wow, I feel like a moron now. I never could figure out why it would be “for wind.”

[–] Thadden@lemmy.world 10 points 22 hours ago (1 children)

Haha nah you're alright. Every day we learn something new! Also another one, "umbrella" is "paraguas" (waters stopper) :)

[–] Akasazh@feddit.nl 5 points 21 hours ago (1 children)

Or parapluie (rain stopper)

[–] OfCourseNot@fedia.io 4 points 19 hours ago (1 children)

Nope that's French, I think, my French est terrible, but definitely not Spanish.

[–] Akasazh@feddit.nl 3 points 19 hours ago (1 children)

Yup I didn't take intend it to be a Spanish example btw, just to show that the para prefix works in other languages too.

So how many panels does it take to power your average kitchen fridge? I estimate that a single modern rooftop-style panel could pull it off. Is there a battery being used in this setup? I suppose you wouldn't need one if you're only storing drinks that don't need to be kept at a safe temperature 24/7. Regardless, I wish the article would have asked these questions.

[–] marci@sh.itjust.works 5 points 9 hours ago (1 children)

A single 72 cell panel and a recent DC driven solar direct drive compressor. With older technology it takes about 4 12V panels to start the compressor running SDD without batteries. I’m product manager for SDD driven DC compressors used in WHO off-grid fridges and could elaborate quite a while if you’re interested further.

Not to be "that lemming", but, please do. Super interesting.

[–] ayyy@sh.itjust.works 1 points 14 hours ago

Is “a panel” a standard size/unit? (Genuinely asking, I assumed there are lots of different sizes but a standard would totally make sense from a cost savings perspective.)

As far as your question, the main challenge would be the required battery because the startup load of a compressor is waaaay higher than the operating load. A single refrigerator barely uses much power once it’s going.

[–] shalafi@lemmy.world 2 points 16 hours ago

Given the semi-arid landscape, I'm betting it's cold at night, no need to run the fridge.

[–] PieMePlenty@lemmy.world 8 points 23 hours ago* (last edited 23 hours ago)

Not a lot. Maximum power a fridge would draw is around 150W and it will work for about 8 hours per day so 1.2 kW. A 1 m² panel should provide enough power and energy, even with conversion losses. You'd need a battery though.

[–] RvTV95XBeo@sh.itjust.works 8 points 1 day ago

My kitchen fridge is relatively new, uses ~1.25 kWh/day, typically draws ~100W when running and never really goes over 200W

My garage fridge is older and cheaper and uses about the same amount of energy, but power occasionally spikes >1kW

With batteries, both could be powered with just ~200 W worth of panels. Without batteries, you may want a little more power or a descent capacitor to make sure you can handle the start-up loads.

Given it's out in direct sunlight all day, you may need an extra 200W or so to offset the solar hear gain.

A typical rooftop panel is ~300-400W, so 1 would probably do it.

[–] Jimmycakes@lemmy.world 3 points 1 day ago

Probably like 3

[–] Deebster@infosec.pub 108 points 1 day ago (1 children)

Imagine stumbling upon a fully operational pink refrigerator, stocked with cold beverages, nestled incongruously in the heart of this arid wilderness. It's not a hallucination or a mirage—it's a deliberate and whimsical creation by the Namibia Tourism Board, designed to surprise and delight weary adventurers.

Those two sentences pretty much cover it.

[–] jonathan7luke@lemmy.ml 48 points 1 day ago (5 children)

Why can't the world have more of this and less of... everything else that's going on right now? 😕

I don't really have a point, it's just sad that humans have the capacity to do such cool, fun, creative things, and instead we're burning the world down so computers can churn out garbage and blowing each other up because we're different from each other.

[–] Postmortal_Pop@lemmy.world 8 points 18 hours ago

Because people with whimsy are always poor.

I just saw an amazing concert at a venue built and paid for by the local government of a nearby town. You can only get tickets through the venue (no Ticketmaster), parking is free, prices are reasonable and it is an absolutely beautiful venue that artists want to perform in.

This is in a very red state (and very red town) in the US. There's still some good stuff out there if you look away from the horror show that's our federal government.

[–] 667@lemmy.radio 21 points 1 day ago (1 children)

Because if it doesn’t generate shareholder value, corps are not interested.

[–] ryannathans@aussie.zone 2 points 1 day ago

Green power drives shareholder value, and most places where fossil fuel wins economically it is largely due to government subsidies

If there was no shareholder value in green power, we wouldn't have any substantial green power. Yet the rise in green power over the last few years is absolutely mind boggling (and very under reported)

[–] otterpop@lemmy.world 4 points 1 day ago

Be the change you want to see in the world! Even if it's something small you could help things be better.

TLDR: Theres a solar powered pink refredgerator in the Nambian Desert.

[–] limer@lemmy.dbzer0.com 9 points 1 day ago

Cold drinks await

[–] Quilotoa@lemmy.ca 6 points 1 day ago

The government put the fridge there to attract tourists.

Feeling serious Stephen King vibes... careful with opening that door!

[–] aramis87@fedia.io 8 points 1 day ago

I wonder how often they have to restock it?
