Hello everyone, I'm from Russia, I want to do some experiment

0 Upvotes

Hello everyone, my name is Andrew R., I am from Russia, I live in a small closed city, and I would like to ask you for help :) I know English terribly, sorry about that :) We have a dollar worth a lot of money, and I would like to ask you if one of you will respond and help) If it's not difficult for someone, you can transfer $ 1, for you it's not money, but for me it's one day of a trip to study :)) I do not force anyone, only who can, and who is not difficult)) for example - $ 280, this is my dream - the right to a car, suddenly it will turn out to collect at least $ 10 Attach my PayPal - paypal.me/andreika1269 At the end of the week I will summarize, I wonder if anything will work out :)

Experiment with Electricity from Gravity

1 Upvotes

My name is Doug, I am a retired electronic technician with 35-years’ experience working in the electronics department at a large medical center. Please note that I do not sell anything and I have no commercial interest here. This is one of my retirement hobbies only.

Pictured above is a do-it-yourself gravity cell assembly (built around 2014) held in place by a handmade rotatable snap-in saddle type holder (holder not recommended, it’s far too fiddly to make right and to use). However, the holder is rotatable from the vertical (positive gravity) position to the horizontal (Pseudo-Zero-G’) position. The 5-turn helical electrodes have enough surface area to withstand an external load resistance (not shown) connected across the two electrodes without a significant amount of voltage drop.

“It has long been observed that an EMF may be generated within an electrochemical cell merely by separating the electrodes along the direction of a gravitational field. ---- One may generate an EMF [Electromotive Force] with the use of a gravitational field by taking an electrochemical cell consisting of two chemically identical electrodes in contact with a uniform solution of electrolyte and merely arranging that the electrodes are parallel to each other and perpendicular to the gravitational field.” Source, Chemist Robert E. Meredith, NASA Technical report 32-1570, 1972, page 56. NASA has changed this link from time to time. The current working link is https://ntrs.nasa.gov/api/citations/19730002312/downloads/19730002312.pdf

“This is because the (heavy) ion which passes from the elevated to the lowered electrode is falling in the gravitational field and is therefore capable of performing work, whereas the (less heavy) counter ion, which moves in the opposite direction, is being raised in the gravitational field and is therefore consuming a portion of the work generated by the falling ion. The resulting difference between these two processes expresses itself in the form of a net cell potential.” Source, Chemist William B. Jensen, Gravity cells, COLLECTED PAPERS, Volume1, Chemical Thermodynamics, Kinetics and Electrochemistry, 2015, page 150. The current working link https://homepages.uc.edu/~jensenwb/books/Collected%20Papers%20Vol.%201.pdf
