The Quran confirms his virgin birth, and a chapter of the Quran is entitled ‘Maryam’ (Mary). The Quran describes the birth of Jesus as follows: (Remember) when the angels said, “O Mary, God gives you good news of a word from Him (God), whose name is the Messiah Jesus, son of Mary, revered in this world and the Hereafter, and one of those brought near (to God). He will speak to the people from his cradle and as a man, and he is of the righteous.” She said, “My Lord, how can I have a child when no mortal has touched me?” He said, “So (it will be). God creates what He wills. If He decrees a thing, He says to it only, ‘Be!’ and it is.” (Quran, 3:45-47) Jesus was born miraculously by the command of God, the same command that had brought Adam into being with neither a father nor a mother. God has said: The case of Jesus with God is like the case of Adam. He created him from dust, and then He said to him, “Be!” and he came into being. (Quran, 3:59) During his prophetic mission, Jesus performed many miracles. God tells us that Jesus said: “I have come to you with a sign from your Lord. I make for you the shape of a bird out of clay, I breathe into it, and it becomes a bird by God’s permission. I heal the blind from birth and the leper. And I bring the dead to life by God’s permission. And I tell you what you eat and what you store in your houses....” (Quran, 3:49) Muslims believe that Jesus was not crucified. It was the plan of Jesus’ enemies to crucify him, but God saved him and raised him up to Him. And the likeness of Jesus was put over another man. Jesus’ enemies took this man and crucified him, thinking that he was Jesus. God has said: ...They said, “We killed the Messiah Jesus, son of Mary, the messenger of God.” They did not kill him, nor did they crucify him, but the likeness of him was put on another man (and they killed that man)... (Quran, 4:157) Neither Muhammad nor Jesus came to change the basic doctrine of the belief in one God, brought by earlier prophets, but rather to confirm and renew it.

Thanks for the heads up. I thought this was a video about making a long lasting gravity generator, like the ones used in old clocks and outdoor camping lights. I appreciate you clearing that up and not wasting my time.

[@Iam_Grim]

A tank type water heater design would lend itself really well to this kind of chemical battery design vis a vis replacement electrodes, system flushing, and inhibiting evaporation. Adapting the pressure valve to vent at a lower pressure than a typical hot water tank would prevent pressurization of the battery, too.

It may be less confusing to call these specific gravity batteries to indicate the density of the liquid is what the gravity is referring to. 😉👍 I'm planning multi day battery backup for my home and flow batteries are definitely on my radar 😀

Density. For sure. The dunce CAP Dynamo’s may be too dense to grasp the gravity of your words.

Was thinking of a big chunky weight pulling on a cord wound around a spool and using some kind of multiplier gear. Technically that stores energy by use of gravity, and would qualify as such if you don't differentiate with such details.

I began collecting various items along the railroad tracks out here in central California. One interesting item I've found are Edison battery oil bottles. They have Thomas Edison's signature embossed on one side. The railroads had large banks of batteries stored in concrete vaults burried in the ground usually near a signal crossing. I've always wondered what battery oil was. As always, no matter the topic, you provide informative and entertaining videos. I think this could become a good science fair project.

i was thinking of using aerobic compost piles of livestock manure and hay/straw with actinomycetes (the potentially flammable "firefang" lower fungus that can cause spontaneous combustion in compost piles) that heat up to 32-60 degrees celsius, releasing methane and carbon dioxide. If you could harness the methane while separating it from the carbon dioxide also released by the actinomycetes' aerobic composting process, you could burn the methane to generate electricity in a type of rocketstove system of pipes with a long elongated slope to run the length of, zigzagging slowly upward, the inside of a glasshouse to warm the plants organically so that you don't need non-organic energy from external supplies to heat glass houses of plants like say tomatoes or strawberries in winter..., while releasing but trapping the carbon dioxide inside the glasshouse to feed the plants so they can convert that into oxygen, this while generating electricity by heating water with the burning methane elongated zigzagging rocketstove to heat the glasshouse interior, to turn a turbine to heat sand batteries for longer term storage of the heat/energy generated by the actinomycetes of the aerobic compost pile? The sand batteries the heat of which is not used to heat the glasshouse as is the previous stage of the system mentioned? It could also power lights inside the glasshouse to extend the daily photoperiod of the plants to increase their vegetative growth cycles (of photoperiod plants), thus preparing enormous plants with renewable localised energy supply, generating electricity and heat and compost in one go, in the middle of winter even prior to spring? I'm not really sure about separating the methane from the carbon dioxide generated by the aerobic compost pile, though. Only a small amount of photosynthetic available radiation (PAR) is needed to fool the plants into thinking they are experiencing a longer day cycle I wonde if it could generate enough electricity though (The compost pile, to have a machine turn itself in its container inside the glasshouse? I mean aerobic compost piles need to be turned to continue the process successuly.

Just an idea that might work or be fun to try. . If you make a long tight coil of copper wire and drop a strong neodinium magnet down it it will produce power which can be stored in a capacitor and then fed to a motor driving a worm drive raising more magnets to the top, where they run down a slope before dropping into a funnel at the top of the coil to drop the next one down and produce yet more power etc etc.. Obviously the worm lift would need to be made from plastic or wood and the tube the magnets ride up of simalar none magnetic material. Just think it might make a fun perpetual motion device? Or if not actualy perpetual then a small winding handle or a switchable battery to raise a number of magnets to the top ot the coil, to "prime" the system.

A bit off-topic, but I remember many years ago seeing a report on TV about a pilot scheme set up by one of the Australian universities to use lead-acid batteries in cars (nothing new), but replacing petrol stations with stations where you could change the electrolyte.

It discusses the formation and stabilisation of the ICl interhalogen allowing for an additional electron transfer reaction by the I+/I2 couple on top of the existing I2/I- couple (the latter mirroring the Br2/Br- couple of the Zinc Bromide battery).

[@justinklenk]

A true gravity battery, wherein a weight is raised, to provide later energy by its descent powering electricity generation, is the most ideally efficient battery we have - the only losses are any infinitesimal friction on the way up/down, and the loss of energy in the raising mechanism's energy transfer/powertrain and the loss of energy in the conversion of the descent to electricity to use, that last one obviously being the biggest, and in fact the ONLY truly significant loss in the whole system. That's why they are the (theoretical and actual) best possible battery that can exist, PERMANENTLY retaining 100% of its originally-stored energy (so it's not subject to electrical batteries' depotentiation over time in storage, nor even long-term chemical breakdown like gas or reagents, nor container seepage like hydrogen, nor pressure loss over time like air pressure, nor loss of a compressed material's springiness/rebound potential - it's just PERMANENT, PURE potential kinetic energy, eternally waiting for its triggered descent and simultaneous conversion to kinetic energy)... And, end-to-end, something like a 99.something-percent systemic storage efficiency, in practice.👍 It's god damn perfect!!

@@SasquatchTrevor no, the volume of the liquid and the density of it would determine the capacity, how long the battery can run, but the size of the... I guess anode and cathode is the correct term, could determine either amperage or possibly voltage.

[@SasquatchTrevor]

@vidard9863 Right. That's what I meant. With zinc/bromine, the more electrolyte you have, the greater the capacity. I don't know about how it charges, though.

[@SasquatchTrevor]

@vidard9863 Wait, I remember now. So, with this type of battery, the electrolyte is the active material. All that the electrodes act as is a current collector. As the battery charges up, the zinc plates out on the anode, and bromine collects at the cathode. The concentration of zinc bromide will go down, and the conductivity will drop. I'd imagine that would have an effect on the voltage and current used to charge it up. From what I have seen of this type of battery, is that often something like sodium bromide is reacted with zinc sulfate to form the zinc bromide. The sodium sulfate that is left over is left in as a freerider electrolyte. That has the benefit of maintaining conductivity.

Correct me if I'm wrong but the first "battery" was a generator that generated current from a chemical reaction that could be renewed with the addition of reactants while the second "battery" was in fact a rechargeable battery that stored power from a chemical reaction but the stored current needed to be renewed from an external source. The first should be much more useful for longer-term applications.

Correct, the first is a _primary_ cell, the second a _secondary_

@@MostlyPennyCatIs it possible to manufacture a battery depicted in the first case, of a size that would allow producing, for example, 48 volts of energy and use it to power a 3-kilowatt inverter, for instance? And what quantities of materials would need to be considered in such a case?

[@MostlyPennyCat]

@@pauliuspetronaitis1763 Well, the primary cell has an output of 1 Volt. So you'd need 48 cells (a _battery)_ to create 48V. Also we don't know the internal resistance of a cell. Every cell in existence can be written as two components, a cell (or battery) of so many Volts and _zero_ resistance and an in-series resistor of some Ohms. To calculate for a battery of cells, you just add up the voltages and the ohms. This gives you the maximum current the battery can provide. From that, you can calculate how much power and current you can generate. Using: V = I*R P = V*I I = V/R Therefore P = V²/R To _reduce_ the internal resistance of a battery, you wire batteries in parallel because then the formula for internal resistance becomes: 1/Rt = 1/R¹ + ... + 1/Rn So you invert (divide 1 by R) all the individual radiators and sum them, then invert that number to get the total resistance. Example: Two 100 Ohm resistors wired in parallel. 1/100 + 1/100 = 1/50 1/(1/50) = 50. 50 Ohms. Two resistors (or batteries) of 100 Ohms wired in parallel have a total resistance of 50 Ohms, half the separate batteries.

@@pauliuspetronaitis1763 Turns out this is a improvement on something called a "Daniell cell", you can look it up on Wikipedia.

Instead, a layer of zinc sulfate sits on top of a layer of copper sulfate, the two liquids are kept separate by their differing densities, often with a layer of oil added on top to prevent evaporation. _*_This reduces the internal resistance of the system and thus the battery yields a stronger current."_* Unfortunately it doesn't tell us what the internal resistance is, just that it's improved.

I wonder if it would work as a gel.

At first I was like "who would think you could harness gravity for electricity?" but then I remembered the internet.... But I did think you were going to discuss using weight and a gearbox to spin a motor to generate electricity.

We must both be working on the same project.

I'm surprised😮. I thought a gravity battery was a mechanical battery system that used available energy ie solar or hydro to push a heavy material against gravity to a height where it was locked off until required. For example, using daytime solar power connected through a gearbox to an electric motor to lift the weight. At nighttime or whenever power is needed, the weight is slowly dropped which spins the the motor (DC) and generates electricity. So I was very surprised to see you demonstrating a chemical battery.

This project seems to be more based on chemistry than gravity. All gravity seems to do is keep the chemicals that all have different properties " in place" to produce energy. I thought a Gravity battery stored electrical energy as potential energy until needed. Could someone please educate me on this. I must be missing something in my understanding of this subject that I just learned about less than an hour ago.

I expected copper (storing energy by pumping water up) but found gold, or actual copper and zinc.
