Applied science: alternative energy source

The reserves of oil and metal on Earth will at some point be exhausted. The creature is entirely different. They are reproducible - meaning they are "immortal". There are many projects to research alternative energy sources based on biotechnology. This source of energy can be obtained from plants, from garbage and from . organisms themselves.

Experts from the US Agricultural Research Organization, led by Dr. Charles Lee, devised ways to use mushrooms as biofuel. More precisely, the ear fungus (cat ear mushroom) is very easy to grow in Southeast Asia. Atrium is often used as food. It has the ability to extract a degrading yeast for absorbing nutrients. Scientists decided to genetically engineer, responsible for producing this enzyme. If it not only decomposes wood, but also disintegrates other waste, it can be taken from both ethanol as fuel.

Ohio University researchers have found a way to utilize eggshell as a fuel because its main ingredient is calcium carbonate. When heated, it turns into calcium oxide, which can absorb carbon dioxide.

A German farm owner, Christian Koch, invented a device to treat any kind of biological waste including weeds in the garden. The ' ingredients ' in the pot are heated to 300 degrees Celsius, making the hydrocarbon separate. The creative German used the catalyst to convert them into Diesel oil and used it to run his own car.

People also experimented with turning daily waste materials into fuel from improving domestic waste treatment technology. After sorting, organic waste is put into a special device for composting, composting, fertilizing vegetables and ornamental plants in the garden. The inorganic substances are added to the incinerator by pyrolysis method.

The idea of ​​burning garbage in a furnace is not new. Since 1874 people in Nottingham have built the first incinerators. Following their example, big cities in the US like Boston, New York, Philadelphia also do the same. But soon after, the local government found that the way to treat such garbage affects the living environment, especially since plastic products become popular, the burning of garbage creates substances when very harmful to health.

When pyrolysis of solids, it is burned in an oxygen-free environment at temperatures between 400 and 700 degrees Celsius. In the early stages of the pyrolysis process, soot is obtained in industrial use. rubber, and when most of the carbon is burnt will produce a gas that has a composition similar to natural gas, which can be used as fuel. It is likely that in the near future, there will be generators combined with incinerators to recover gas for domestic use and slag after burning will be buried in the waste dumps in accordance with ecological standards.

Recently, MagCap Engineering in Massachusetts cooperated with inventor Gordon Wald of the University of Illinois (USA) to test a device to produce electricity from any living tree. Wald built a device consisting of a metal needle plugged into a tree and an electrical diagram to filter the current and adjust the voltage. Electricity is generated enough to charge the battery of a mobile phone. If the tree is used as a direct power source, the less the leaf, the higher the voltage gain.

Japanese scientists go even further. They built devices that can produce electricity . human blood. Food is the main source of energy. In fact, the capacity of a 'human battery ' does not exceed 100 watts. Theoretically, thanks to this invention, it is possible to plug a light bulb into the body to illuminate the road in dark places or for electrical equipment when there is no other way.
