It’s nowhere near strong enough. Also, if you wanted to complete the cable in, say, five years, you’d need spiders that could produce 80 km of silk per day in completely seamless, continuous strands. :-)Killer Wolf wrote:they should use spider webs, be cheaper

Carbon nanotubes are on the order of 250 times stronger than steel, and the proposed carbon nanotube composite ribbon would still only be able to lift a few tens of tonnes. Spider silk isn’t in the ball game.Killer Wolf wrote:i'd say it was strong enough (10x stronger than steel apparently), esp if woven.
I thought they said in the videos that the material had to be at least 30 times stronger than steel? That would disqualify the spiders, regardless of being cheaper.Killer Wolf wrote:i'd say it was strong enough (10x stronger than steel apparently), esp if woven. it's lighter too. and spiders are cheaper than nanotubes.
