OK engineery type people.

Conservation of energies etc...

If you have a heat source. Say, a rocket heater in a grow house, it dumps a certain amount of heat into the world.

If you harness some of that energy to run something like a Stiling engine to pump some water, it presumably converts heat into motion.

But them what? Where is that energy now?

Does the heat just bleed out of the Stirling engine?

Does that mean you can tap into the heat source without losing any heat overall?

Where does superman get changed now that everyone has a phone in their pocket, and there are no phone booths?

What kind of a place was a phone booth for nudity concealment in the first place?

Is sleep important?


Once you put work into something, the energy imparted is converted into kinetic energy, which is dissipated through friction into heat and entropy.

Superman changes in your mind.

Sometimes it becomes potential energy. Say for instance you used your engine to roll a car up hill and parked it with the brake on... if you take the brake off the potential energy is converted into kinetic energy...

Same thing if you pump water uphill.

Wow..... I only discovered Aquaponics like four weeks ago, and in the meantime I read TClynx's thread (very instructive - very good place to start), JT's thread (beautifully build system, easy to get intimidated ..... But good read), Bullwinkell's thread (still in the process of recovering... Head-spinning views of worlds that could very well exist. Right? The only flaw I ever could detect is the origin of syrup-wafers. They're really iconicly Dutch. Right up there with windmills and wooden shoes.....).

And then some....

But this one is my favorite. It really reeds like a novel, when read start to finish. Really enjoyed it. And learned a lot.

Hope to hear from you again soon, g2n!


Aww, thanks! :)

Greetings from up the road. Was wondering how the greenhouse and fish were doing over the winter as I have gotten the bug and have been planing a Aquaponics greenhouse my self?


I brought the tilapia in for the winter, but I really don't want to do that again. I think I'd prefer to switch to trout, if the tilapia will hurry up and get big enough to eat, or I can find someone who wants to trade trout for them, or something.

The system does okay over the winter. Some things overwinter fine in it, and others don't. My strawberries did, and were producing bright and early this spring. :) My baby fig trees did too, and are quickly overgrowing one of the grow beds, so I've got to find places to put them.

Heating the water without heating the greenhouse, which is what I tried to do last winter (to see whether I'd be able to keep it warm enough for tilapia) was kind of a disaster; nothing seemed to like having warm feet and cold heads, and everything got fungusy and died. Also it rained on me every time I went in, from all the condensation. This winter I didn't heat the water, and stuff did a lot better, and I didn't get nearly as wet. :)

...or maybe koi. Then I can have more angst-relieving fish to stare at, and not have to dread having to eventually kill them. :-/

My thread got a narrative? When did that happen? Dang, I need to start paying better attention!

So what is the topic?

Pancakes or medications?

I can't honestly take a thread off topic until I know what the topic is meant to be :dontknow:


Offtopic *is* the topic, here. :headbang:

As Bullwinkle often gets his thread mixed up with this one, the only thing off topic here is... I will leave that at the discretion of G2N.


Sure, Ron, leave ME to answer the HARD questions! ;)

Yes, but potential energy must become kinetic eventually. So all you are doing in that regard is storing it. But like a battery, it can only last so long, before either the vessel fails, or the energy leaks out.

I*ve had a bit of a crack at making stroopwafels, but after 4 days of fails, I decided to turn them into cinnamon buns (or something)

Anyway, here's a video of my attempt...

Ha, you really made me laugh! They are so readily available here I think nobody even bothers to make them at home. At fairs and such there sometimes is somebody making them fresh - they usually are larger, more like 20cm in diameter... We have - and like!- so much stroopwafels here, that we even use the crumbs to make stroopwafel-icecream. One of my personal favorites!

I'm really confused now. Bullwinkle mentions Mrs Bullwinkle so often I thought she was a he.
It must be him, oops I mean, her.... coz the kitchen looks just like I imagined.

That's not really me.

I just enjoyed how crazy she seems and for a minute, wished I were her :)

I am a he. And Mrs Bullwinkle is a she.

Sadly my kitchen looks more like I imagine sane people's kitchens look. I'm not sure her kitchen would pass our rental companies quarterly inspections :)
