I think #verticalfarming has a place, they were just doing it wrong: https://www.fastcompany.com/90824702/ver.. Use #lightpipes for lighting only aided with #ultraviolet , get rid of the #warehouse and just have a #concrete base, with #natural #wind #cooling . Keep #labour #overhead low and only bother #growing #profitable #crop . #robotics and #tech should be avoided unless they are *required* - not just a way to get more #funding .
Really nice #coffee #table #design made from #concrete https://hackaday.com/2023/01/13/concrete.. This really does show that #concrete can be used with #wood to make #longlasting #stylish #furntiure . One day if I ever have my own place, I will consider doing something like this.
#building a #concrete #printer could be cool: https://hackaday.com/2022/10/25/build-yo.. I think the #killerapplication is #furniture and #bespoke #concrete parts that could be #built #offsite .
One point of #anecdata - but it appears that some #us #infrastructure has suffered from lack of #maintenance http://rachelbythebay.com/w/2021/08/18/i.. When you can see the #rebar coming through the #concrete on a #bridge - it's really quite serious.

If you check out #simulations of the #dam #failure - it would be absolutely devastating: https://www.youtube.com/watch?v=RjHWkCdZ.. The reason for the interest is that there has been massive #flooding in #china - and reports of several #upstream dam failures. There is also a #typhoon on the way, potentially a catastrophic series of events.
