Three caverns will be created, each measuring 300 m (984.25 ft) in length, 40 m (131.2 ft) in height and 20 m (65.6 ft) in width. These will be filled with hot water by a pair of 60-MW electric boilers, powered by renewables when it's cheap to do so. Pressure within the space allows for temperatures to get as high as 140 °C (284 °F) without the water boiling over or steaming away. Waste heat from industry will also feed the setup, with a smart control system balancing energy sources. The Varanto facility is reported to have a total thermal capacity of 90 GWh when "fully charged" – enough to meet the year-round domestic heating needs of a "medium-sized Finnish city." ]]> engineering finland district-heating energy energy-storage caves cool https://pinboard.in/ https://pinboard.in/u:jm/b:61b9f95a1e1e/ 2022-04-19T09:21:24+00:00 https://birdnetpi.com/ jm audio birds birdnet automation raspberry-pi cool identification https://pinboard.in/ https://pinboard.in/u:jm/b:34e78fcfa03f/ 2022-02-09T11:34:15+00:00 https://audioprimate.blog/2017/06/28/diy-cables-braiding-video-essentials-from-the-interwebs/ jm cables braiding cool https://pinboard.in/ https://pinboard.in/u:jm/b:8146f66f088b/ 2020-06-09T13:53:01+00:00 https://www.youtube.com/watch?v=1hs451PfFzQ jm videos youtube rng prng hacks cool via:reddit https://pinboard.in/ https://pinboard.in/u:jm/b:b574b7569ac3/ 2020-04-21T22:15:37+00:00 https://james.darpinian.com/satellites/?special=starlink jm starlink satellite cool google gmaps streetview web https://pinboard.in/ https://pinboard.in/u:jm/b:21084d1f8cd1/ 2020-02-20T22:48:06+00:00 https://all3dp.com/2/how-to-3d-print-your-own-lithophane/ jmLithophanes are essentially embossed photos generated by a 3D printer.

Pretty cool, no? Now, in theory, you can just construct an SQL query, send it to Athena, and then do whatever you want with the results. No more: Updating OSM planet data yourself; it gets updated on AWS whenever OSM publishes it, once a week. Transforming the data into a query-able format; Athena handles that for you. Query/request frequency limits (it’s still AWS though, so other limitations might apply 💸 💸) At door2door, we had a pretty straight-forward use-case for this: we needed to get buildings in specific regions based only on where they were, and transform those buildings into GeoJSON that we can attach our data to, and visualize on the front-end on top of our base map. ]]> athena osm buildings aws geodata mapping maps door2door cool hacks https://pinboard.in/ https://pinboard.in/u:jm/b:1507124525ff/ 2018-09-25T14:55:09+00:00 https://schemestats.bike/blog/post.php?s=2018-09-23-dublin-bikes-revisited jm bikes cycling dublin dataviz cool https://pinboard.in/ https://pinboard.in/u:jm/b:5a5321cb944b/ 2018-07-05T09:42:58+00:00 http://sundial.singleton.io/ jm sundial sun laser-cutting cool making makers time https://pinboard.in/ https://pinboard.in/u:jm/b:9fbd006f0e54/ 2018-01-25T10:58:58+00:00 http://www.openculture.com/2017/08/3d-scans-of-7500-famous-sculptures-statues-artworks-download-3d-print-rodins-thinker-michelangelos-david-more.html jm 3d-printing art history british-museum models cool https://pinboard.in/ https://pinboard.in/u:jm/b:f50eceb70273/ 2017-06-21T10:40:31+00:00 http://sploid.gizmodo.com/a-neural-network-turned-a-book-of-flowers-into-shocking-1796221045 jm art dinosaurs ai plants deep-learning graphics cool https://pinboard.in/ https://pinboard.in/u:jm/b:d52ad79a2804/ 2017-03-10T17:19:54+00:00 http://codegolf.stackexchange.com/questions/88783/build-a-digital-clock-in-conways-game-of-life/111932#111932 jm life games alife conways-life gliders hacks cool https://pinboard.in/ https://pinboard.in/u:jm/b:8f9329e09710/ 2016-10-12T10:53:14+00:00 https://www.ianvisits.co.uk/blog/2016/10/12/the-private-monorail-tunnel-under-north-london/ jm power monorail transport london underground tunnelling electricity cool https://pinboard.in/ https://pinboard.in/u:jm/b:bf9d6b1e773d/ 2016-06-20T10:16:13+00:00 http://www.atlasobscura.com/articles/holloways-roads-tunneled-into-the-earth-by-time jmAppearing like trenches dragged into the earth, sunken lanes, also called hollow-ways or holloways, are centuries-old thoroughfares worn down by the traffic of time. They're one of the few examples of human-made infrastructure still serving its original purpose, although many who walk through holloways don't realize they're retracing ancient steps. ]]> cool hiking geography roads paths holloways psychogeography lanes https://pinboard.in/ https://pinboard.in/u:jm/b:6aa20d466786/ 2016-05-04T12:37:40+00:00 http://www.lovehulten.com/brixsystem.html jmThis conceptual collection consists of eight 6:1 scale versions of classic LEGO bricks, each fully functional in one way or the other.
