propaganda to get everyone to feel good about drones.

Humans aren't the only animal that likes to catch a wave

They were sittin' on top of the world.

Random thought: why don't we have hundreds of little wee inexpensive (relatively) drones in the deep ocean, swimming around taking readings and photos/video? I guess power is one issue but if you designed it right (i.e. to move slowly and not use too much power) perhaps it could surface and recharge with solar cells or something?

You mean the worst part. Dolphins are assholes.

No surfing opinions since 1998.  At least I didn't go to law school though.

It couldn't even kill one?? Your tax dollars at work, people.

Not mine. I live in the USA!

Huh. Must have been in Lake Constance. I thought those Austrian drones were more reliable than that, though.

Wonder if there's ever been any competitions that got out of hand and ended in beachings.  Heh.

Austrian drone? If I want to see an Austrian drone, I'll rent Red Heat!

Gee, it's almost as if intelligent animals somehow know about the importance of play

It is always fun to watch animals play.

Can we stop equating quadcopters with drones. There is a huge difference between an RC helicopter like this:

and a military instrument of death like this:

Article wouldn't have been nearly as good without the dig at SeaWorld at the end.

Power and money are the restricting factors. There are currently 3,000.  http://www.argo.ucsd.edu/

Not the power, the pressure, if you want to go to any real depth.

This is fascinating:

At the bottom of the Marianas Trench, however, the weight of seven miles of water overhead means that the ambient pressure is about 1,100 atmospheres.  That's a different of 1,099 ATM between Mr. Cameron and the outside of that 40-inch sphere he's jammed into.
What does that mean though?  1,100 ATM is just an abstract number.  OK.  Well, in Cameron's own words, it's so great that the steel sphere in which he travels to the bottom actually shrinks measurably during descent.  One analogy the Deep Sea Challenge team uses (and I quoted yesterday) is that 1,100 ATM is equivalent to inverting the Eiffel Tower and resting its point on your big toe. Ouch. Now imagine another Eiffel Tower for every square inch of your body.  A second way to think about it is that 1,100 ATM is about the same as the peak pressure that occurs in the chamber of a handgun for a fraction of a second after the bullet fires.  Unlike the gun, however, the pressure in Challenger Deep is sustained and pervasive.  It's like living in a moment frozen in time, inside an explosion.  If the sub had rivets to pop (which it doesn't), they would literally become bullets inside the sphere.  1,100 ATM is also a little less than the pressure in a commercial water cutter that uses a high pressure jet of liquid to cut patterns out of steel.  It would certainly be enough that after that imaginary rivet popped, the ensuing water jet would slice soft human tissue like butter.  Of course, not for very long, because the weakness in the vessel would likely result in catastrophic implosion and instantaneous death for the unfortunate occupant.


We might get pictures of a giant squid, Godzilla, and the Mighty Cthulu (sp?)

The Eiffel tower weighs a smidge over 16,000lbs (1,100 atm x 14.7 psi/atm)? Seems a little improbable.

ChiliBoots: The Eiffel tower weighs a smidge over 16,000lbs (1,100 atm x 14.7 psi/atm)? Seems a little improbable.


I don't think that's how it's calculated.  It's not a straight multiplication.

Way over my head, and I ain't doin' the maths:

Hydrostatic pressure at depth h beyond liquid surface is given by the formula: 
p = p₀ + ρ∙g∙h 
p₀ atmospheric pressure at liquid surface usually p₀ = 1atm = 101325Pa (1Pa = kg/ms²) 
ρ liquid density 
g gravitational acceleration 

So at 2500m depth: 
I prefer to calculate in SI-units first and then convert to atm 
p = 101325Pa + 1000kg/m³ ∙ 9.81m/s² ∙ 2500m 
= 24.626325×10⁶ Pa 
= 243atm

Remote control plane != drone

Also, dolphins are wild, you don't need  to say "wild dolphin".   I realize you're trying to make it sound more interesting but it just sounds lame.

and they could've found that recent lost plane...and Amelia Earhart's, as well, if the things could travel far/wide enough....
