Okay, so the drones are...

They specialize carrying things over a long distance, right?

And they use batteries to do this.

They do.

They eat batteries.

All right, yeah.

So could you sort of just...

tell us a little bit about that

yeah so in order for the drone to be able to fly you need to supply it with batteries and depending on how far it has to fly you have to supply it with more batteries so um there's a baseline cost of like four batteries i believe currently um so in order to fly at all you need to give it four batteries and then for every let's say 1000 meters i believe then it costs an extra battery as well

So the price in batteries increases over distance as well.
