THEORY: HUMAN BATTERY=

Placing your hands on the metal plates causes the effect of a battery charge. Your hands contain a thin film of sweat that produces a chemical reaction similar to battery acid when placed on the metal plates. Your hands take negatively charged electrons away from the copper plate and transfer them to the aluminum plate, causing it to be negatively charged. The variance in charges between the places produces an electrical current which flows through your body and displays on the meter.

In the version where the human's hands are wet, the reading on the current meter is higher than when the hands were not wet. The human body resists the flow of current through the skin. When wet hands are placed on the plates, the resistance to current is decreased thus increasing the flow of current and creating a higher result on the meter.

 ELECTRICITY FROM WATER:

Chemical energy stored in different substances can be converted to electrical energy. This ability is the foundation of design of all batteries.

Each battery has two poles usually made of two different metals. One pole is the positive pole and the other is the negative pole. Electrons can travel from negative pole to the positive pole via a conductor such as a wire.

A flow of electrons in a conductor is called electricity and if large enough, it can be used to make electro magnet, light up a light bulb or run an electric motor. Inside each battery there are chemicals that cause such chemical reactions. These chemicals in general are called electrolytes.

Biodiesel refers to a vegetable oil- or animal fat-based diesel fuel consisting of long-chain alkyl (methyl, propyl or ethyl) esters. Biodiesel is typically made by chemically reacting lipids (e.g., vegetable oil, animal fat (tallow)) with an alcohol.Biodiesel is meant to be used in standard diesel engines and is thus distinct from the vegetable and waste oils used to fuel converted diesel engines. Biodiesel can be used alone, or blendeD

Applications

Biodiesel can be used in pure form (B100) or may be blended with petroleum diesel at any concentration in most injection pump diesel engines. New extreme high-pressure (29,000 psi) common rail engines have strict factory limits of B5 or B20, depending on manufacturer.[citation needed] Biodiesel has different solvent properties than petrodiesel, and will degrade natural rubber gaskets and hoses in vehicles (mostly vehicles manufactured before 1992), although these tend to wear out naturally and most likely will have already been replaced with FKM, which is nonreactive to biodiesel. Biodiesel has been known to break down deposits of residue in the fuel lines where petrodiesel has been used.[5] As a result, fuel filters may become clogged with particulates if a quick transition to pure biodiesel is made. Therefore, it is recommended to change the fuel filters on engines and heaters shortly after first switching to a biodiesel blend.[6]

Properties

Biodiesel has better lubricating properties and much higher cetane ratings than today's lower sulfur diesel fuels. Biodiesel addition reduces fuel system wear,[29] and in low levels in high pressure systems increases the life of the fuel injection equipment that relies on the fuel for its lubrication. Depending on the engine, this might include high pressure injection pumps, pump injectors (also called unit injectors) and fuel injectors.

The calorific value of biodiesel is about 37.27 MJ/kg.[30] This is 9% lower than regular Number 2 petrodiesel. Variations in biodiesel energy density is more dependent on the feedstock used than the production process. Still these variations are less than for petrodiesel.[31] It has been claimed biodiesel gives better lubricity and more complete combustion thus increasing the engine energy output and partially compensating for the higher energy density of petrodiesel.[32]

Biodiesel is a liquid which varies in color —between golden and dark brown —depending on the production feedstock. It is immiscible with water, has a high boiling point and low vapor pressure. *The flash point of biodiesel (>130 °C, >266 °F)[33] is significantly higher than that of petroleum diesel (64 °C, 147 °F) or gasoline (−45 °C, -52 °F). Biodiesel has a density of ~ 0.88 g/cm³, higher than petrodiesel ( ~ 0.85 g/cm³).

Biodiesel has virtually no sulfur content, and it is often used as an additive to Ultra-Low Sulphur Diesel (ULSD) fuel to aid with lubrication, as the sulfur compounds in petrodiesel provide much of the lubricity.
