Reply to comment by fredsam25 in TIL that all the gold that has ever been mined in all of human history could fill about three Olympic-sized swimming pools. by westondeboer

Not at all, gold leaf has all kinds of applications. For example, it’s the best material for spacewalk sun visors.

But spread out on a tennis court, it's pretty wasteful.

You can still use it after.

Gold is easily recycled

Good luck scraping gold leaf off a tennis court.

Do you understand how easy it is to recycle gold off electronics? What makes you think a tennis court would be a difficult surface to separate gold from?

You dont need to remove it from the tennis court, you can dig up the whole tennis court and dissolve the gold in a solution and reconstitute it as a purified ball of gold. You can just shovel the whole thing into a smelter and melt it off. Everything not gold will float to the top.

This is a non-event, if people are willing to dig a mile underground through quartz and granite using explosives and mercury baths to get gold dust out of the ground, why do you think a tennis court will be any type of obstacle? It would be picked clean that day.

The wind would blow half of it away.

People pan for gold dust in the streets of NYC. You are underestimating how quickly that wafer thin gold will be pulled up by whoever is working it.

You're better off not putting it on a tennis court in the first place.

You just burn the court and separate the gold from the ash.

It would just blow away with the smoke.

Nah, gold dust is too heavy. It's a common separation/reclamation technique for gold in old flumes or carpets or other materials in workspaces where fine gold particles were common.

You're thinking of gold particles. Ultra thin gold flakes are easily carried away in the wind. The ratio of surface area to weight mean that they experience a lot of drag relative to gravity.

And you don't think a fire will alter the flair structure.

The melting point of gold is around 2000F. No way you are getting anywhere close to that in a open tennis court fire. The gold will not be effected by the fire except to be torn apart by the plumes of smoke that would also carry it away.
