The Serpent remotely operated vehicle (ROV) from Seaview Systems is designed for exploring very small-diameter pipelines. It can investigate conduits as small as 9 inches (23 cm) in diameter, and fit around bends with a radius as narrow as 27 inches (68.5 cm). Measuring 9 inch x 9 inch x 57 inch (23 cm x 23 cm x 145 cm) and weighing 70 lb (32 kg), the Serpent runs on two 300W brushless DC motors that give it a total forward thrust of 18 lb (8 kg). With a 0.5 inch (1.3 cm) diameter fiber-optic tether, it can explore as far as 6,000 ft (1,830 m) down a pipe or tunnel. A 360-degree pan/orbit/zoom color camera and two color cameras are included, along with two 70W high-intensity LEDs. The robot also has heading, pitch and roll, and depth sensors, as well as sonar. A fiber-optic telemetry system provides up to three video channels, four RS232 channels, and two RS485 channels.   (Source: Seaview Systems)

William, I wasn't sure where your (usually) straightforward statements ended and tongue-in-cheek started, either. Re Google, I know what you mean: it's getting harder and harder to find good basic info instead of commercial/sales info. But that result was predicted when the Internet became commercialized.

Ann, it was not completely clear when things turned, so you did a good one on me. About Google; I have had quite a bit of serious frustration when attempting to find information about some product or system and the dumb google search instead turns up a hundred sites that want to sell me one, even if they don't have it and have no concept of what it is. At that point it becomes a first rate time waster.

But on the other topic, while invisibility in the normal sense is a big challenge, being un-noticed is a lot simpler, hence the comment about the missile launching dolphin and such. Consider how easy it would be for you to pass somebody by if a whole crowd were wearing AnnThryft masks. Spotting the real one is a challenge if they all look similar.

Glad you enjoyed my sarcasm, William. All kidding aside, Google can be a useful tool, but one must know how to evaluate sources.

Isn't that the truth. That's why I'm using trusty old Google. It never fails!

William, I am very suspicious now about who you work for. I'm going to go Google Freddy the Fish and DARPA.

Now I can't tell if you're pulling my leg about DARPA and Freddy the Fish. ?

Ann, OK, that makes sense. Of course a missile launching fish would be a very interesting creature. Probably we could train a school of dolphin to escort a missile launching robot dolphin, giving it a nearly perfect cover. The main hazard would be poachers. Perhaps DARPA would be interested in that concept, which just popped into my head. I am not at all familiar with the DARPA dolphin program and have never heard of "Freddy the Fish".
