🌻 I'll stop freakin' out about this soon, promise.

Made some pasta sauce(ground beets, tvp, kale, garlic, zataar) and left it out for 45 minutes in the vacuum tube, in the afternoon sun. Turned out so good.

@neauoire please keep sharing. This solar food cooking tube is so interesting.

@neauoire every time you post about this i think of the Mr. Wizard's World (80s kids science show) episode where he cooks breakfast on a variety of solar contraptions, including some shiny metallic funnels on sticks!

8 year old me thought it was the coolest, of course, but these vacuum tubes are even more neat.

The episode is available here: youtube.com/watch?v=3bObVFVu_3

@beardicus that show's intro animation alone was worth the detour, wow!

@neauoire it's really cool tech, i first found it through Kirstren Dirksen video of a nomadic shepherd (13:30 onward)

@neauoire that's so cool!! can you still use it on overcast days?

Devil Lu Linvega

@lrlna we tried it only once overcast(it has been sunny recently), and it still worked, but it took almost twice as long.

@neauoire same concept is used for more industrial power generation using these vacuum tubes filled with oil that would then get used to generate steam I believe as a source of power for turbine electricity generation. You’d have a small field filled with one long long tube in a single closed system.

Did one summer internship at a renewable energy research facility and it was fascinating I learned so much.

🌻 Hell yeah solar cooked brown rice.

@neauoire That looks amazing ❤️ How do you clean this, though? 🤔

Devil Lu Linvega

@moonglum the tray has a standard bolt fitting at the end, and we can screw on a round scrub pad. We've been using it twice a day everyday this week, and each time we use it, the steam seems to clean the left-over of what we cooked before.

@neauoire Seeing the vacuum tube work so well is so cool!

daniel

@neauoire oh we got one of those as well! It’s extremely satisfying to cook from virtually nothing

Devil Lu Linvega

@C418 Oh cool! What have you tried cooking with it?

daniel

@neauoire not much, just veggies. I do wanna bring it to a park and cook some Hot Dogs though

@jfmblinux aliexpress sells them, there's a bunch of outlets depending on your location.

@neauoire can/should one use oil? Or how does sauce-making work in this thing?

Devil Lu Linvega

@geography yeah, we made potatoes with olive oil as one of the first recipes we tried.
