This is version 0.1 - it will get much better. Anything you can think of, they’ve thought of and it’s on their roadmap.

Lofty ideas, supported only by hope. People can dream up solutions as much as they want, doesn't mean it's going to work. 99% of startups fail, this one will be no exception to the stats. Sure, they might succeed, but there's no guarantee they'll make it past this super basic PoC.

Ideas that will make their startup better that are realistic, highly likely they are considering:

- 50 drones not one - make sure they don’t run into each other - drones of different sizes and speeds - watch out for power lines - watch out for birds - don’t run into planes - don’t ruin the scenery for hikers by always being aloft - make sure they are charged - use as first line of defense before the humans come - make sure they can’t be hacked

I don't think this would even be able to put out a single tree catching fire. Generally the fire is too vertical and the extinguisher would land on the ground and not be activated by the heat, so it won't go off until flaming branches fall down, at which point the fire is too large.

You’re referring to a canopy or crown fire. It depends on conditions, of course, but it usually takes time for enough heat to build up that a fire crowns. There’s generally a period where it will burn through the lower and mid stories and it spreads.

In the area they show in their video it doesn't look like it'd take much for the trees at the edge of the clearing to go up in flames, and pretty fast too.
