Ummm how exactly would banks give you 900m for 100m in collateral?! Can you make an example?

It’s not banks but I think the GP is trying to describe a margin loan. Basically you give (say) an exchange $100, ask them to buy $1000 worth of stuff using your $100 as margin, and if the stuff you bought looks like it is going to be worth less than $900 (ie if they would make a loss by selling all your stuff) they will call you and ask for more collateral or, if you are too slow, sell all your stuff for eg $925, leaving you with a less of $75.

there are Over The Counter (OTC) trading desks/companies who can help with that. One of them is Circle. I think Kraken also offers this service.

cool! you got a link?

That’s pretty exciting, especially the doubled field of view

Hmm... all small scale projects. Point to point Drone delivery as killer application is still not possible in Switzerland. Need special permission for each flight/route.

If you're thinking of an Amazon type delivery (and not, let's say delivery of industrial goods, medicine, ...), the audience would not be there anyway.

Notably, major online retailers trialed same-day delivery (usually via bike messenger) within major urban regions (e.g. Zurich) for a moderate charge. Customers generally agreed that it was a great option, but no one used it, so it got canned.

So here is a solution: send a drone overhead and just ignite the methane via laser. no more methane!
