SFOGuy says...

Well, watching events (snowboarding and downhill)---it has surely been windy---would have scrambled a drone show good and proper...

So; I understand this was all sort of manufactured for the broadcast? Or more properly: because people were standing underneath the drone area during opening ceremonies, NBC fell back on video tape of the dress rehearsal?
Anyone else understand this to be the case?

So THAT'S why power companies are supposed to trim trees

SFOGuy says...

And thanks for your elaboration---I didn't know.
Not sure how you solve the engineering problem ---no one likes to lose power and sticks hit lines but...
Maybe there needs to be some sort of clever answer?

The automatic reclosers are so power can be restored quickly if a stick or debris hits the lines and can be quickly destroyed by the electrical arc. This saves a trip by a lineman to inspect the area before restoring power.

Thank you for that explanation!

Power lines are protected by breakers, although the max current is obviously very high compared to the household sort. Apparently some power companies have installed "reclosers", which attempt automatically to close breakers that have tripped, restoring power. These have been implicated in the recent California fires:

Sounds totally nuts, but customers do hate to lose power.

Not just throwing rocks, but---what is the practical application of this? As a pleasure craft, maintaining all those extra hydraulics would drive maintenance expenses through the roof from the perspective of a recreational boater.
I'm also concerned about reliability, elevation of center of gravity, response to being sideways in a seaway... the second half with the outrigger "sled' maybe would have application in military stuff? Air/Sea rescue?

Green screen special effects are amazing to me

SFOGuy says...

I guess I should have been able to draw that conclusion, eh?
But---I hadn't drawn the direct line between the two techs.
Or maybe, it's more one tech?

impressive, but not surprising that it can be done in realtime.

basically the same tech that is used for AR/VR, just has to sense+record the movement of the camera precisely.
