free power from excess water 3

[themiltman]

i have water pressure of 100kpa most of the year how is a cheap way to turn this into power

Hi Keith Thanks for making me 24,999
I was that in my class as well.
But I thought possibly this could
have been California teminology,
up here in Minnesota the only
reference close would be keyboard
wart! although you can't see it in
the pic. the output plug is really short.

My pleasure mach.

Smoked and Mach,

I think a translation is needed - at least by me...

Translation:

Re-checking this thread I saw that my two pictures one of a 'wall wart' one of a 'cord wart' were screwed up and in fact both of 'cord warts'. So I put up a correct picture of a 'wall wart' stating, "this is for", the 1 out of 25 million (M) people who don't know what a 'wall wart' is. (as apposed to 1 out of 50 who don't know what a "cord wart" is)

machmech responded "Thanks for making me 24,999
I was that in my class as well." Which if I look at closely confuses me too.!

"Here is a "Wall Wart", (for the one person out of 25M who doesn't know)"

25M = 25000

To 'modern' engineers M means mega = 1,000,000.

The problem that I think you are having with that concept machmech is in assuming that all notations are derivative of Latin, they are not.

Ah but keith forgot the space, so for me the interpretation
is a quantity of a production count. This is the way Job
tickets are written It allows larger numbers to be placed
within a small box. He was describing the populace and not an electrical sum.

I think Keith is outstanding but had a little problem
thinking out side of the box!

25M = 25,000
25MM = 25,000,000

Now if he would have posted 25 M[Ω]- This I understand to be mega ohms.

Nice list of definitions by the way, I don't have this many
in my electrical manual.

Can anyone imagine the incredibly small amount of liquid contained in a yoctolitre? Can't get much free power from that!

(I think I deserve points for wrapping this tangent back into the original thread subject).

Jeff,

I first thought that it would be a split molecule contained in a yoktolitre of water. But checking Avogadro's number (yes, I had forgotten the exact value!) I think that there are about 30 dihydromonoxide molecules in a yoktolitre of water.

Going to the SI unit yoktogram makes the whole idea impossible. There is nothing like a yoktogram of water!

[jraef]

So instead of using a euphamism for ignorance by saying "His glass isn't filled all the way to the top", I can now say "His yoktolitre of water has only 28 dihydomonoxide molecules"?

That will be usefull in a conversation...

 

[itsmoked]

Yes, yes! Except when you're derailed by the five minute explanation of what a yoktolitre is.

Jeff,

What do you mean by "I think I deserve points for wrapping this tangent back into the original thread subject"

Did you?

Anyhow. Here's that PLS you deserve so well.

"Can't get much free power from that" was my attempt at wrapping back to the "free power from excess water" theme of this thread. We have diverted off into tangent land again of course, but thanks for the PLS anyway, even though I was forced into blatant self promotion to get one!
