And bonus points if you have a creek uphill that you can divert to the top of a vertical chute in your tunnel system to send it over a drip-grid when temperatures are slightly freezing: not too cold to have the creek still running, but cold enough make the water form icicles from the drip grid. Pass by once a day to kick down newly formed icicles, building an ice reservoir at the bottom of the chute. I know a brewery that solves all their cooling needs with this method.
(no idea if they reinstated that system in the oughts, when starting to advertise as "all renewable", or if they just failed to update to electric refrigeration long enough that it eventually became fashionable again - hardly more than a century of "yeah, perhaps next year, I'm busy!")
- RicoElectrico 4y agoSounds interesting, but I'm not sure if I understood correctly. Can you provide an illustration?
- usrusr 4y agoEdit: yeah, totally the wrong thread, sorry. Implementation of the icicle thing is really simple, divert the creek (or parts of it) onto a wooden contraption that would split it into many small trickle-streams. Trickle streams small enough to make them freeze into icicles. Occasionally, take some plank or pole to bang the icicles off the wooden contraption, this needs to be done before they grow so heavy they overload the frame. Have a cellar/chute deep enough to not fill up to the top in of winter. Do a Google image search for eisgalgen (none of the examples are from a natural stream and also no directly above the chute implementations) (original reply) In Excel, a cell with a formula has two faces, the formula and the result. An implementation of "plain csv, but with a way to run formulas" could simply branch out to using separate files, particularly if you already have an a UI that's good at working with more than one file. Technically, the additional input file would be unnecessary, because all input data could all be in the formula file, with some shorthand for "identity transformation". (still original wrong thread reply, nothing new below) The more I think about it, the "hashbang part" could even be designed to work as an actual script, sending the file (or files) to an interpreter that produces the result stream to stdout. Add an interface for doing cell by cell interactive updates and you'd have full independence between the implementations of UI and formula syntax.
- the_third_wave 4y agoPosted in the wrong thread, I assume? The relation between Excel cells and beer-cooling icicles is tenuous at best.
- usrusr 4y agoThanks, now my mind is going through a what-if where Clippy is educating us about natural all-year beer cooling techniques!
- dotancohen 4y agoYou've never had an Excel formula freeze the computer?
- the_third_wave 4y agoOnly when it involves large amounts of negative numbers.
