It came from a speaker a few years ago at the Davos World Economic Forum. Davos is where the ultra rich gather each year to plot out how to be even more evil.

Oh, right! I forgot about all of the LIDAR-equipped planes in maritime communities! Those are way more economical to fly than any sUAS. /s in case that wasn’t obvious.

In case you, or anyone else, were vaguely interested in learning:

-kelp extent mapping needs to be done in repeatable fashion, specifically at low tide; we can put up an sUAS any time

-the communities most in need of monitoring absolutely cannot afford to send planes up monthly

-many of the kelp beds in the PacNW are in restricted airspace; it is much easier to get an FAA clearance to perform low-altitude surveys using sUAS

-that restricted airspace I mentioned? Some of these kelp beds are on approach paths for the airspace. Even if a plane were the preferred choice for surveying, the planes are unable to fly in the pattern we need

-(drifting a touch off your point of LIDAR-equipped planes) satellite imagery with the required resolution is prohibitively expensive

-most construction projects wouldn’t use a plane for tasks such as volumetric or area analysis

Consumer drones are quickly becoming the preferred, economical means for kelp health analysis, especially for communities that can’t afford planes or purchasing satellite imagery.

This “lonely adult” uses drones for aerial mapping and survey. This Summer’s huge project is a workflow I developed to map the extent of PacNW bull kelp forests in order to provide year-over-year health metrics. Using sUAS for this is way more automated, economical, repeatable, and granular than using airplanes and satellites, therefore within reach of those communities monitoring kelp health.

DJI hits the sweet spot of capabilities, compatibility, and cost. Skydio (go USA!) has abandoned the consumer/enthusiast market that built their business. And even before they turned their back on the consumer market, Skydio couldn’t come close to DJI’s hardware. Additionally, Skydio, in true capitalist fashion, locked capabilities away behind software licenses, capabilities that are already built into the drone.

It’s important for countries to have domestic drone manufacturing in the current conditions. But the USA’s actions here smack of protecting companies that just can’t hang.

Stainless steel that gets coated is no longer stainless steel. Stainless steel requires exposure to sufficient oxygen in order to maintain the protective oxide layer.

These are rudder bolts from the same gudgeon on my sailboat. The black stuff is anoxic corrosion.
