1. Geobacter bacteria battery
Geobacter is a genus of proteobacteria, which uses what is called anaerobic respiration, this refers to the oxidation of molecules in the absence of oxygen to produce energy. Geobacter was found to be the first organism with the ability to oxidize organic compounds and metals such as iron, radioactive metals, and petroleum compounds. The body produces these metals and their compounds into harmless carbon dioxide during the use of iron oxide and other metals available as an electron acceptor. Geobacter Case metabolized through the creation of "pili" columns width of 3-5 nm, which act as conduits for electrons passing between the raw material and Geobacter. This form of consumption has led scientists to theorize that Geobacter could act as a natural battery. In a recent BBC article, Energy Secretary Spencer Abraham said
"The genome of this tiny microorganism may help us solve some of our most difficult problems and to generate clean energy through energy sources based on biology."

2. The battery of spinach
Following the example of nature, scientists researching plant photosynthesis have developed a type of solar energy source that uses spinach. The process of photosynthesis is driven in part by a protein complex called photosystem I (PSI). This protein complex converts sunlight into energy for plant growth, but also produces a small, but it is still possible to measure the amount of electricity. The researchers dell ac adapter used this knowledge and this protein complex between two layers of transparent conductive materials, creating a small production of cellular energy. Although still in early development, it is certainly an interesting step in the direction of insurance more readily renewable energy sources.

3. Protein battery
Dallas Researchers at the University of Texas have discovered a protein that is said to have the ability to behave like a battery, capable of receiving, storing and distributing electric charges. The protein called Sprouty2 "groups into larger particles that are able to store electrical charges internally. Within the group, bonds and the electrical state are protected by the cells surrounding the environment, and can not be discharged by normal biochemical methods, ie the load is maintained until the recipient is appropriate, giving a great potential for further development in a natural battery efficient.

4. Stacks of fruit and vegetables
While it is not feasible to feed more than one lamp or small radio, any fruit or vegetable that is acidic or contains electrolytes can be used as a sort of rudimentary battery. By inserting two different metallic objects, like a copper coin and a galvanized nail, which can create an electrochemical reaction that generates a small potential difference. By connecting many lemons, potatoes, apples, etc. in series can produce enough electricity for larger objects. Below is a picture of a battery of 500 pounds of potatoes could feed a small sound system. Pretty neat.
5. And the battery has passed
As one of the few animals on the planet with the ability to make, store and discharge electricity, the electric eel is the oldest battery of nature. Eighty percent of the body of an electric eel is occupied by three pairs of abdominal organs that produce electricity. The organ of Sachs, which uses low-level electrical pulses for navigation, and Hunter's organs and high voltage emissions produced. The electric organs are composed of electrocytes. These electrocytes are stacked in a sequence, similar to a dry cell battery. Each cell can store and download 0.15 volts. 4. 000 of these cells discharged at the same time, the shock can reach 600 + volts, easily enough to cripple or kill a human being with repeated shocks.
6. The Baghdad Battery
The first man known fact batteries, known collectively as the "Baghdad Battery" were found in Khuyut Rabbou'a, a city near Baghdad to the present in Iraq in 1936. These artifacts are believed to be the parity (between 250 BC and 224 AD), because the city was excavated in births in the time domain, but the actual age of these batteries is undetermined and a subject of dispute among scholars.
The artifacts consist of tall terracotta pots containing a copper cylinder made of a copper foil laminate, which houses a single iron bar. At the top, the iron rod is isolated from the copper by asphalt plugs or stoppers, and both the rod and cylinder fit snugly inside the opening of the bottle which bulges outward towards the middle (reverse hourglass .) It is believed that the jar was full of lemon juice, grape juice, or vinegar, which acted as an acidic agent to produce the electrochemical reaction with the two metals. In replicas made today (including an experiment on Mythbusters) have shown that the "Baghdad Battery" could produce enough electricity to be used for electroplating, or electrical stimulation.

7. The battery of virus
Since the energy used by current mobile devices require energy for longer periods of time, new technologies will be necessary to hp compaq nc6000 ac adapter go beyond what is provided by the batteries today. One of the most interesting and potentially promising technologies have been developed by researchers at MIT, through a combination of genetic design and directed evolution of viruses. However, Professor of Materials Science-Ming Chiang and chemical engineering professor Paula Hammond, have led the virus to have an inorganic material are arranged in crystalline structures in a polymer layer. After gold doping to improve connectivity, resulting in what looks like a sheet of cellophane. These viruses assemble the components of the battery can store three times more energy than traditional materials by packing highly ordered materials in a very small space.

8. Earth Batteries
As with fruit and vegetable batteries, electric current can be created by two conducting plates located at different points in the series electropotential, black (or in this case buried) in some kind of electrolyte. In a battery of "land" of the electrolyte is the ground itself. One of the earliest examples of an earth battery was built by Alexander Bain in 1841. Bain was the first to construct an electromagnetic clock and the development of a single system to run the mechanical device. Bain buried plates of zinc and copper in the ground about a meter away and use the resulting voltage of about one volt to operate a clock.
