I'm prepared to give you credit. I'll just need corroboration from

So now you're denying that there is an entire industry finding and repairing water leads through concrete structures? Or have to deflected this to my memory? That's it isn't it? You are so jealous that with an education you became nothing and with hard work I became successful, you'll do anything and say anything to attack me.

I think your claim is false. If it's true, don't deflect. Give your
evidence.

(Such a successful person should know how to do that!)

I have no intentions of telling you any more.

That's an effective admission that your claim was false. Thanks.

By the way, I did notice that you purposely changed the subject from me saying that there is an entire service for finding and repairing pool leaks to your trying to say that I have one on the market.

1. I never said that my design was marketed because it was 100 times more sensitive than the customer's requirements were so they dropped their plans for an "improvement" since it would detect the normal leakage through solid concrete.

2. I don't even know who this English Company was since I was developing it through an intermediary to the specifications of the contractor.

It would appear that it is your problem that you cannot understand simple English. Are you slipping into dementia? If so you can brag you have something in common with Joe Biden.

I did design and program such an instrument. It also had a digital readout. But rather than use it, in testing we discovered that it was too sensitive and the company retained the instrument that the company I was working for designed in the first place. I was also in the process of reengineering it to identify the position of Roof Leaks on commercial buildings when the contactor I was working for had to return to his normal full time job.

You need to take notes to keep your fables consistent.

Alternately, just read upthread to help remember what you said last.

The game changer, of course, is the Li ion technology since if was so easy

Li-Ion also has its issues. For example, even top brand manufacturers do
not seem to understand that it is not a good idea to top off a Li-Ion
battery at close to 100% charge and then leave the bike in the garage
that way. This results in premature aging and loss of capacity. The
smarter way is to offer 80% or so which is plenty for a short ride into
town. Then let users top it off in the morning when they expect to go on
a very long ride. In the same way, don't ride it all the way down to
where the low-batt cutoff turns it off, at least not often.

"Smart" battery chargers would seem to be in order. Push the button if you
need more than an 80% charge this time for some reason.



NiMH would be more robust, but that chemistry never seemed to catch on
before Lithium came on the scene.


NiMH doesn't have an adequate energy density. A NiHM-battery that can
last 40-50mi would be unreasonably large and heavy.

Is the old stranded concrete ship still there?


Use..the SS Palo Alto.
About two years ago the winter storms broke the last 1/4 of the stern off
and it twisted about 80 degrees from level.

When I was a tad one could actually walk out to the bow. Then it was
fenced off at half way. Then when I came back from college and other things
it was closed off entirely and you can only walk out to the end of the pier
the ship abutts.

Sigh. Things change.
Concrete exposed to water saturation degrades surprisingly rapidly. One of the instruments I was working on detected leaks from degrading concrete is swimming pools. I would imagine that you could make a pool thick enough to delay this for a long time as those concrete barges showed. But degrade they will. The concrete turns back to almost a mush consistency.

Oh, you mean like the Alvord Lake Bridge that was built in 1889 in San
Francisco, CA. This bridge was the first reinforced concrete bridge,
and it still exists today, over one hundred years after it was built!

Or maybe the Hoover Dam? Constructed some 85 years ago and still
standing. Up to this time, the largest scale concrete project ever
completed.

Yup, wrong... again.
Concrete is a mixture of fine and coarse aggregate bonded together
with a fluid cement that hardens (cures) over time. In the past

The aggregate is of course sand and gravel, or "crushed rock". The
cement actually comes in a hag, labeled "cement".

So Tommy, you are wrong again.

Don't you ever get tired of being such a buffoon?

So now you have reached the point where you don't even use Google.
You just make your moronic comments with your usual complete ignorance
of the subject: https://en.wikipedia.org/wiki/Types_of_concrete

No, you read it.

Modern concrete
Typically, a batch of concrete can be made by using 1 part Portland
cement, 2 parts dry sand, 3 parts dry stone, 1/2 part water.

Which is basically what I wrote above
"Concrete is a mixture of fine and coarse aggregate bonded together
with a fluid cement that hardens (cures) over time."

Good Lord! You don't even understand what you are arguing about.

I gave you the reference to what I said, that concrete varies in what it is made of and for from a number of different things. But of course you're telling us that the Boulder Dam was made with "Portland" cement when that is not the case.
