It's curious there's no video, since they're already crop-dusting. Even searching on the internet didn't turn up anything. BTW "piker" is slang for giving up, not the best startup connotation! (though mightn't be widespread)
> Pyka has developed a placeholder business doing crop dusting in New Zealand. That helps it earn $600 per hour while logging the hours necessary to prepare for the human transportation market.
It depends on what "developed" means, but the next sentence seems to say they are currently earning $600 ph from it. I suppose it could be parsed to mean that a hypothetical "business" earns that.
