Willaim Thomson's ( water condenser - electrostatic )

[jadaro2600]

Lewin of MIT gave a demonstration of William Thomson ( Lord Kelvin )'s water dropper.  Claimed to be a battery of sorts, driven by gravity, this device, old news as it may be, could generate a large voltage differential.

My question is, what patent number is it? ..I can't seem to find any of his patents in the normal locations, (save for maybe a few regarding instruments to measure electrical pressure), nor any patents prior to patent number 1 million uspto for that matter.  Does anyone have a list of Lord Kelvin's patents?

I have searched both USPTO and UK databases.

You should look up how the patent system came about in the first place. You may find it interesting.

Not all inventions have or need patents. The intelligence in how a device works comes from the Creator. The inventor only steps on what already is there.

After all this lecture!, just google "Lord Kelvon's experiment", or on youtube:

this is true, and thank you for the information. However, the patents would be nice to find, after all, the patent system came about in 1790, and he invented this in the 1890's.

The idea of the patent cam about as the result of a king of england granting a state-sanctioned monopoly to a stained glass manufacturer (circa 1449).

The king ( king henry iv ), probably trying to profit from the out-fitting of churches.

Last year I did Lord Kelvin's Generator even better than his, I used Rain Gutters on both sides of my house roof to conduct the experiment.

it works very well, I dismantled the wires because it gave me a spooky feeling that it would attract lightning.

all you need is two rain Gutters, Some length of insulated wire, two water pales to connect the wires to and feed the water into the pales.

keep the pales off the ground.

I call it the Lord Kelvin's Rain Gutter High Voltage Generator.

so far I am the only one that I know of that has built Lord Kelvins device in such a manner.

unfortunately only in german.
It shows that there is also some effects with magnets.
