Re: Good concept but other leaks are bigger problems.

Cabe, can you clarify your question? What kind of blockage and what problem do you think that causes?

The bot itself does cause some level of blockage... I wonder how that will be handled...

The most common gas leak detection system is the human nose, simply because there are so many of them around. Not the most sensitive, but the most common. That is the benefit of moving more of the system outside, which is that leaks are detected befor a gas buildup leads to an explosin.

William, good point about vulnerabilities in other parts of the gas pipeline system. San Francisco has experienced occasional problems like the ones you describe, usually by utility workers, who you'd think would know better.

We mentioned several leak detection methods currently used today: visual inspection via cameras, acoustic sensors, hydrostatic or liquid natural gas testing, and aerial patrols.

This looks like a great idea. Not knowing how leak detection is conducted today, however, I'm wondering how big of an improvement this would be on existing methods. Does anyone know -- what's the current conventional method for detecting leaks in gas pipes?

This is really a good invention, and it appears to exploit a new concept and mechanism of detection. So i is a great idea. BUT in this area, just outside of Deroit, the last few gas explosins have been due to damage done to the small pipes feeding individual residences and businesses. The invention would not detect those leaks, which were not smallleaks anyway. So while it is a great addition it is not the only tool that must be used. Unfortunately the worst disasters seem to be caused by poor judgement and avoidable human errors, at least around here.

The result is that all gas meters are being moved to outside of  all the rbuildings.

Ann,

The technical specifications, I think, would make for great reading because of the bot's  incredible small size and speed. Hopefully, such info will be made available as the technology evolves through addtional research and testing. Again, great article Ann.

mrdon I, too, wish we'd gotten more details on the hardware design, especially considering its speed/size ratio. Let's hope we get an update soon.

Certainly a great invention and will definitely increase the safety level.

Lots of people who write about robots say they give us jobs, instead of taking them away from humans. Based on the evidence in some recent studies, I'm not so sure.
Aerojet Rocketdyne has built and successfully hot-fire tested an entire 3D-printed rocket engine. In other news, NASA's 3D-printed rocket engine injectors survived tests generating a record 20,000 pounds of thrust. Some performed equally well or better than welded parts.
Purdue researchers have used a commercial sewing machine to quickly create stretchable electronics from conventional thin wire and a silicone elastomer used for making special-effect movie masks.
