A DIY saltwater battery, also known as a galvanic cell, uses the principles of electrochemistry to generate electricity. It's a simple battery constructed using two different metal electrodes (like copper and zinc) immersed in a saltwater electrolyte (typically a solution of salt in water). The difference in reactivity between the metals is key. The more reactive metal (like zinc) undergoes oxidation, losing electrons and becoming positively charged ions (Zn2+). These electrons flow through an external circuit connected to the two electrodes, creating an electrical current. The less reactive metal (like copper) acts as the cathode, accepting the electrons and undergoing reduction. The saltwater solution allows the ions to move freely, completing the electrical circuit. The voltage produced is relatively low, depending on the metals used and the concentration of the salt solution. However, multiple cells can be connected in series to increase the overall voltage. The reaction will eventually cease as the more reactive metal is consumed and the less reactive metal is coated with reaction products, limiting the duration of the battery. Note that this type of battery is not rechargeable in the traditional sense.
Dude, it's basically two different metals (like a copper penny and a zinc nail) in salty water. The salty water lets the electrons flow between the metals, making a little bit of electricity. It's super simple, but it won't power your house!

A vanadium redox battery (VRB) is a type of flow battery that uses vanadium ions in different oxidation states to store energy. It works through redox reactions, where electrons are transferred between different vanadium ions. The battery consists of two half-cells, each containing an electrolyte solution of vanadium ions dissolved in sulfuric acid. One half-cell contains V2+/V3+ ions (vanadium(II) and vanadium(III)), and the other half-cell contains V4+/V5+ ions (vanadium(IV) and vanadium(V)). During charging, an electric current is applied, causing electrons to flow from the V2+/V3+ half-cell to the V4+/V5+ half-cell. This results in the oxidation of V2+ to V3+ in one half-cell and the reduction of V4+ to V5+ in the other half-cell. During discharge, the process reverses, and the electrons flow back from the V4+/V5+ half-cell to the V2+/V3+ half-cell. The energy is stored chemically in the vanadium ions, and the amount of energy stored is proportional to the volume of the electrolyte solution. Because both half-cells contain vanadium ions, the issues of cross-contamination and electrolyte imbalance that affect other flow batteries are avoided. The battery is also very robust and has a long cycle life.

LOL, dude, antigravity batteries? That's straight-up sci-fi! No price tag on something that's not real.
From a theoretical physics perspective, the very concept of an 'antigravity battery' is problematic. The current models of gravity, particularly general relativity, do not allow for the local cancellation or negation of gravity. Even hypothetical concepts like exotic matter with negative mass-energy density are highly speculative and pose significant theoretical challenges. The question of cost, therefore, is moot; the technology itself is not currently feasible within our established understanding of the universe's physical laws.
