more than 100 years after Tesla's.
In my experience with plastics those 3D printed forms become porous. With hydrophilic materials like Al or glass they will take absorb water into the structure. Spill a Coke on it and see for yourself. Porous Al will probably not be very resistant against corrosion either. And if you varnish it to close the pores, sooner or later the varnish will peel off.
It's a Mazda from the 1970s. Don't ask me how I know.
Medical diagnosis by computer
Most real diseases are easily to diagnose. Computer-generated diagnostics may seem to be a godsend to doctors. Unlike real doctors the computer program does not need to shy away from diagnosing hypochondria.
The trouble starts when the patient goes to a real doctor for a second opinion.
(Mine is the one with the DSM-IV in the pocket)
Serial killer tool
Perfect for booze drinking competitions against real enemies.
What's it for? Broken legs? Pneumonia? Rashes? Sore throat? Renal failure? No doubt doctors are stupid, but most of a diagnosis can be had from just asking the patient plus a few routine tests.
A political party??
Chalk and blackboard are nice for small audiences. If someone in the audience is rude, I can always throw the sponge at him.
Flipover for 200+ people? I don't believe it. Not even in Switzerland.
Referendum next, I guess.
It's simple biochemistry. Anaerobic bacteria can use NO2-residues as electron acceptors, transforming them into amines -NH2. Aerobic bacteria use oxygen for that purpose. Antibacterials like metronidazole (Flagyl) are reduced by a similar process and kill the bacteria in the process. I don't know whether TNT is antibacterial. Might be worth a try.
The obvious countermeasure against such a gadget - if it ever makes it out of the lab - would be to jam it with the real thing. If there is a detectable signal from a buried bomb, it would be easy to make a thin dilution of the same explosive in some suitable solvent and then drip it slowly from a car driving the same route.
This would overload the bomb detector with substance carrying the same signature as the hidden bomb. Detecting a low signal against a high and fluctuating background would be hard indeed. Then give all roads the same marking, whether there are bombs there or not. So there will be false alarms all the time.
