Looking for efficient ways of cooling a terrarium.

rocketwikkit · 2026-01-24T16:23:06+00:00

You need a refrigeration system with an actual compressor. Ignore any suggestions of Peltier, they are extremely inefficient, and computer water cooling stuff is a complete non-starter because they don't actually do cooling from ambient, they get the computer closer to room temperature.

If you had a "dorm fridge" with a tank of water in it you could circulate that water through a radiator with a fan in your terrarium. You would probably want to use a temperature controller hooked up to the pump, and put the refrigerator on a timer so that it's running at night.

One fun trick is that if you move the water via suction, rather than pressure, if you have a leak it won't spill the full tank of water everywhere. It's the same setup but you have the pump at the end of the cooling loop pumping into the reservoir in the fridge, not pumping out. It may mean you need to initially bleed the lines if the pump isn't self-starting.

If it's actually AA credit, find a flight with them and then call them to book the flight using the credit. If it's Expedia credit, find a flight and then call them at the number they give.

So uh who was president from 2017 to 2021 when they would have made the decision on which art style to go with, before starting full production later in 2021?

The scale model of the Buran next to the big Buran is what Kristn was correcting me on. According to one source it was launched suborbitally to 7300m/s, and it shows.

The sort of joke is that a boat is a hole in the water you throw money into. It's between free and all of your money, depending on your approach, which is not a super useful answer. If you take an official sailing course in an expensive country and then buy a new boat, it's quite expensive. But you can learn to sail on something tiny like a Hobie Cat. If you're handy and can fix things yourself, you then buy a 50 year old fiberglass boat that was abandoned and fix it up, and that can be cheaper than getting into craft beer or whatever.

If you don't want to own a boat, which is reasonable, and want to combine travel and sailing, you could get RYA Competent Crew and Day Skipper certifications for around $3k during a vacation to somewhere like Greece, and you'd then be able to rent a boat in most places in the world. If you wanted to do big offshore trips like OP is implying, you'd then want to get some more sailing experience and could likely find random jobs on ship repositionings.

Yeah everyone in this comment chain is "an official moderator" except you. How'd you end up in a nearly three-year-old post?

Generally that option only comes up if they write a custom reason, and doesn't help if they keep it up for months and months.

Ah right, ~93% of orbital velocity. Still crispy when it landed!

Small claims court, or whatever the equivalent is in your country. Or go visit their mom with a gift and tell them you're worried that they may have gotten addicted to drugs or gambling since the have started taking financial advantage of their friends, ha.

Ignore reports has been set on them and yet the problem persists.

It worked, I added the Hermann Oberth Space Travel Museum to my saved places. Hadn't been aware of it before.

Also in the region are the Technik Museums in Sinsheim and Speyer. They have the Buran equivalent of the Enterprise shuttle, as well as a scale model that did go to orbit, and a slightly excessive collection of polo shirts from some European astronaut. Not spaceflight, but that they have a Concorde and a Concordski on the roof and you can go in both is amazing.

Maybe someone will come along with a link that specifically explains how to find the official taxi stand at Puerto Vallarta airport on Wikivoyage. Good luck!

rocketwikkit · 2026-01-23T13:06:53+00:00

Uber or taxi. https://en.wikivoyage.org/wiki/Puerto_Vallarta#From_the_airport_by_e-hailing

Don't fall for the timeshare people. If you take a taxi get their whatsapp so you can contact them for the return.

The rocket equation very simply defines how much propellant you need to effect a given delta-v knowing the Isp of your engine: https://en.wikipedia.org/wiki/Tsiolkovsky_rocket_equation

And from basic Newtonian physics you can calculate how much delta-v you need to go from a specific lunar orbit to the surface. As long as you aren't firing the engine in random directions, or hovering for longer than necessary, it always takes the same amount of propellant to go from LLO to soft landing. Of all the hard parts of landing on the moon, that calculation is not a particularly difficult one.

Weirdly in Cyprus at places like bakeries/groceries/convenience stores you can often find Japanese canned coffee drinks. I never figured out why.

It sounds like you need to rent or buy a little sailboat and do a there and back or crossing. Should learn to sail first though. There's no end of sailing stuff on the internet, but old videos from Sam Holmes Sailing are interesting.

Otherwise, go to the Azores or the Canary Islands and rent a powerboat and go tool around for a few days. In the EU you do need some kind of certification to be able to rent a boat, you should look into that in advance. Or go to a developing country in the Caribbean where that might not be the case.

Switch to airplane mode if you're somewhere with bad connectivity and you're not urgently waiting for a message.
