This was the punchline I was looking for. The aluminum version seem like a more desirable version at 500g.
- chaoxu 5y agoI wonder if one can hollow out the individual cubes to decrease the weight.
- lapetitejort 5y agoOr you could increase the weight by using tungsten or depleted uranium.
- userbinator 5y agoWith the same dimensions as the one in the article, tungsten would be around 7.3lb, and DU is only slightly lighter. If it was osmium, the densest known element, it would be around 8.5lb.
- ncmncm 5y agoOsmium would evaporate, slowly, and poison you while it did. Strangely, osmium oxide is a gas. Iridium might be the better choice.
- ncmncm 5y agoNow make one out of tungsten. Tungsten is famously hard to machine, but ultra-pure tungsten is supposed to be OK.
