The "Lame" blog, mine blog, is one of the main authors of the app ( me ).

And respectfully it is lame. I cannot see any link at all to your software on your blog, and the posted images were deliberately cut in half so they lost a lot of context. In order to find out actual details of the software I had to google the name in order to find the actual website. That is a big fail in my book.

The lack of links, carved up pics and "generalness" of the blog make it and the /. story look like pure click-bait.

"...can boost 300 to 400 millivolts power to 3 to 5 volts".

Power? Volts? Boost? Huh???

In common vernacular of an EE you refer to voltage as power with the understanding that there is current being supplied. EG This device is powered by a 9-volt battery. So the the use of power in TFS and TFA is not out of line.

The paragraph form TFA is:

All these ambient energy sources, such as the difference in temperature in a pipe carrying hot water and the outside air, can generate 300 to 400 millivolts, which isn't enough to power anything. TI has built an "ultra-low powered" DC-to-DC switching converter that can boost this power to 3 to 5 volts, which is sufficient to charge a battery, according to Niranjan Pathare, senior marketing development manager at TI.

Also while current is a needed aspect, the level of voltage is a defining factor in electronic design.

You could take pretty much any speaker you wanted to, run a jumper to the switch and listen to any phone call you wanted.

Back in the day I had a friend who worked for a phone company. As a part of their QC they had a speaker in their office that was connected to various random landlines in order to keep a check on call quality. (In hindsight the choice of lines is a bit suspect)

He told me a story of one call they heard, about the mother of little johnny calling up a phone sex line (but not knowing it was one) and wanting to know what all these charges were for. The phone sex worker tried to sidestep the issue by saying that little johnny was just talking to "friends". The mother replied "but little johnny has lots of friends". At that point the phone sex worker drop all pretense as to what the calls were about, and the last thing the mother said was "wait until little johnny's father gets home"

One thing mentioned in Marc Rogers article that I am also surpassed at is how do you miss that much data flying out of your network?

A couple of years ago I was a customer site and had to download and install some updates onto an HMI system. Less than 5 minutes after starting this, my client's IT people had connected to the system in question and were poking around trying see why that device had suddenly started consuming network resources. Their attempts to shut it down were annoying to me, but at least they were on the ball when it came to knowing what was normal and what was not normal on their network.

If an experiment works, something has gone wrong.
