Comment: What an Idiotic Design Concept (Score 2) 76

by the monolith (#47785371) Attached to: For $1.5M, DeepFlight Dragon Is an "Aircraft for the Water"
Please bear in mind that 'Water, for all intents and purposes, is an incompressible mass.' We teach this to student divers.

Look at the following points...

Fore-planes - they are curved and cannot act in an 'aerodynamic' manner (wings create lift by causing air to reduce in pressure as the air moves in a longer path over the wing than under it,) so they are really just flow directors, and the curves will create permanent turbulence and disrupt flow behind them - the forward vertical thrusters.

Forward vertical thrusters - turbulent flow will create beta on the blades (uneven flow vectors to different blades) destroying efficiency. The fenestration/cowl that surrounds the thrusters will cause turbulence also.

Forward hull - the hull immediately around the area of the forward thrusters is voluminous and bluff to the flow of water when under way. Turbulence and drag will ensue, and this will run toward the stern gear - thrusters, aft planes, pusher thrusters and elevator.

Stern vertical thrusters - similar flow conditions will exist for these units as they exist for the forward units.

Pusher thrusters - will receive all turbulence created by gear that is forward of their position, and reduce efficiency accordingly.

Elevator - single piece curved flow director, similar to the fore-planes in intended down-thrust effect. Same problems of turbulence and drag. Potential for anti-asynchronous oscillation from turbulence caused by all equipment forward of its position.

I saw the previous version of this craft, the Super Falcon, when it came for a demonstration in Jordan in April 2011, and was unimpressed with what I saw. This concept version is not an improvement. They should get proper designers to work on it, not people that just happened to see an aircraft, or read a few pages of Wikipedia.

Yes, a new species conflict would ensue if you took away the humans and left the rats, cats, dogs etc.. But I see you only want to take the humans out of the equation... Leaving the Lawyers (mutant species already in place) to fight the rats, cats, dogs etc.. That would be so cruel on the rats etc.. Perhaps Mothers-In-Law would equal the fight?

Could this be given to terminally ill patients so that they get the gift of a life time of wonders without all the blisters of from trekking, early mornings, hangovers, late nights, working life, lousy bosses, mosquito bites, etc..
Just imagine being able to gift a full-life world holiday to someone: Machu Picchu, Tierra del Fuego, a life of diving the greatest reefs, gliding the Andes, kayaking the Colorado.

I would have expected someone to raise the possibility of insurance companies mining the information so as to avoid dealing with 'problem' medically compromised customers, or at least increasing the coverage fees to unacceptable levels and thereby driving off the 'problem'. Perhaps that potential new employer wants to know that you aren't medical damaged goods? Perhaps you have to apply to the police or a local authority for permission for something, and they want to use the medical records to check your suitability/mental condition/drink/drugs etc..

I would have expected someone to be making comparisons to 'Gattaca' by this point in time.

Almost every day I dive past one of the Smithsonian biomass accretion modules in Aqaba Marine Park, Jordan. You can see one of the collection modules here.

If only academic departments/institutions collaborated or communicated a little bit more, maybe the research dollar would go a little further?

Instead of using words, how about playing the keyboard as if it were a piano (or any other keyboard-like instrument)

Here is an example of a musical login: pvy89pvvv[890[]vv

For this example, position your right hand with the thumb on the 'v' key, then play the sequence as if they were notes, then listen to C.P.E. Bach - Minuet In G Major for what it should really sound like.

NASA: Curiosity Has Found Plastic On Mars 293

Posted by samzenpus
from the mars-needs-organic-polymers dept.
dsinc writes "Last week Curiosity was able to use its SAM (Sample Analysis at Mars) device to confirm the discovery. A robotic arm with a complex system of Spectral Analysis devices was able to vaporize and identify gasses from the sample, concluding that it is in fact plastic. How plastic formed or ended up on the Martian surface is quite an exciting mystery that sparks many questions. The type of plastic sampled as we know so far can only be formed using petrochemicals, meaning not only that there could possibly be a source of oil on the Red Planet, but that somehow it got turned into plastic. Even more interesting is that oil or petrochemicals used to create this type of plastic are only known to come from ancient fossilized organic materials, such as zooplankton and algae, which geochemical processes convert into oil pointing to the earthshaking evidence that there was once life on mars. 'Right now we have multiple working hypotheses, and each hypothesis makes certain predictions about things like what the spherules are made of and how they are distributed,' said Curiosity's principal investigator, Steve Squyres, of Cornell University. 'Our job as we explore Matijevic Hill in the months ahead will be to make the observations that will let us test all the hypotheses carefully, and find the one that best fits the observations.'" Update: Yes, it's a hoax

So, in a few years time when my body slumps a little more and my ass is hanging down, I can get a 'Sponge Bob' job down the back and another complementary do-hickey up front? This is strangely appealing on several levels. I can see the cost benefit analysis, and why wait for the future; do they need human test subjects?
