00:00:00 --- log: started forth/14.09.09 00:14:08 * DGASAU understands some use of having liquid ammonia at home, as for liquid nitrogen... 00:14:28 Ah, there's some utility in making marks on cattle... 00:15:57 There's also loads of fun to be had with it. 00:16:08 Never underestimate the power of just having fun. 00:16:27 Less fun than with liquid ammonia. 00:16:45 The latter is easy to have at home without any special effort. 00:17:01 Liquid ammonia smells terrible. 00:17:02 You just need to wait for winter. 00:19:53 You could probably make a Stirling engine go very, very quickly if you heated up one side to 2300 degrees and poured liquid nitrogen on the other. :) 00:23:42 You can consider solar cell the same way: the heater is at 6000K, the heat sink is at 300K. 00:24:39 Yet it is stupid since the real efficiency is very far from the ideal due to highly non-equilibrical energy transfer. 00:46:42 ttmrichter: you could melting sand to sicon if you got 2300 degree temperature 00:46:54 also many metal could be melting at hoe 00:47:21 for eg, most sourthen china has the red/yellow dirt, which is rich in Fe 00:53:02 i remmember when was a child, we like to use magnet stone for finding these Fe powerder from sands 00:54:06 if you got the high temperature from solar, you could melting them at home, though this wont be as cheap as industry products, but unlike those, this wont require you a lot to just beginning 00:54:37 You're wrong on that. 00:54:44 It does require a lot. 00:55:11 You can find pictures from that research institute in Uzbekistan 00:55:27 where they have nearly scrapped those parabolic mirrors. 00:56:07 i might use a fresnel len 00:56:48 and maybe buy a solar tracking system, which is about 200 yuan on taobao (a chinese version of ebay) 00:57:34 You need really large lens then. 00:59:42 Note that melting iron the conventional way requires only two ovens (one, if you have carbon source already) and a pump. 01:02:06 they have a video on youtube showing a fresnel lens that could rise to 2300 degree temprature 01:03:17 https://www.youtube.com/watch?v=i_8cynWnAw8 DGASAU checkthis 01:03:42 and this one 4000 degree https://www.youtube.com/watch?v=r1x8zk-z6N8 01:08:05 and that guys got the fresnel len from a projection TV :] cc ttmrichter 01:26:30 --- join: nighty^ (~nighty@hokuriku.rural-networks.com) joined

(using forth as a minimal glue language) 22:16:53 i'm working on some code that spans python and pascal at the moment, and rather than having to keep building wrapper methods when i add something in pascal, i think it would be easier to just use a little forthlike thing as glue. 22:47:54 --- join: mr-foobar (~mucker@49.205.73.166) joined #forth 23:38:44 --- join: Bahman (~Bahman@188.159.232.208) joined #forth 23:50:54 tangentstorm: a link of minotaur ? 23:59:31 xyh: http://equi4.com/minotaur/minotaur.html 23:59:59 --- log: ended forth/14.09.09
