Solar boat is an electrical boat which is powered by solar energy utilizing solar panelsbatteries and other necessary electrical accessories. They are quiet, independent and clean engines. Here, batteries store free energy from the sun. The available sunlight is converted into electric power by solar cells which are temporarily stored in batteries. It is used to drive a propeller through an electric motor. Typically, power levels are within a few hundred watts to a few kilowatts. A specific solar boat can run on solar energy depends on its technical design, the amount of solar cells carried, the solar climate where it is based and its pattern of use.

There are very few grid connections on the seas and inland waters as well as along their banks. People living on inland waterway crafts, houseboats, sailing boats and space stations are dependent on batteries just like the owners of electrically propelled boats. But batteries sometimes discharge and need to be recharged. In this scenario…

Bioplastics

What is Bioplastics?
Bioplastics are the bio based plastics produced from renewable resources like corn starch, pea starch, vegetable fats and oils. On the other hand, conventional plastics or fossil fuel plastics are produced from petroleum. Conventional plastics create more greenhouse gas which is very dangerous for our environment.
Petroleum is very limited resource in the earth. It becomes expensive day by day. One day, this resource will be finished. During burning petroleum products like plastics, carbon is emitted and it causes the climate change. Conventional plastics are harmful by-products and chemicals. In this situation, bioplastics can offer an alternative solution. Sugarcane ethanol is a significant substitute of petroleum in the production of plastic. These bioplastics contain same physical and chemical properties like conventional plastic. They also maintain full recycling capabilities.

Applications of Bioplastics
Bioplastics are used in packaging items. They are also used…

Biomass

What is Biomass?
Biomass is the biological component which is obtained from living organisms of nature. It is also referred as plant based material when energy is produced from biomass. At the same time, biomass is also applicable for both animal and vegetable resultant components.
Biomass is a renewable energy source and it can re-grow quite quickly. Sun's energy is captured by plants' chlorophyll through the photosynthesis process. Here, carbohydrates are created by converting carbon dioxide from the air and water from the ground. They are complex combination of carbon, hydrogen and oxygen.

Basically, plant materials are either broken down by micro-organisms or burned. After burning, carbohydrates are transformed into carbon dioxide and water and release the energy harnessed from the sun. This process is known as the carbon cycle in the earth.In this technique, biomass works like natural battery in order to store solar energy.Appropriate utilization of biomass can enhance the l…

Hygroelectricity

Image
For long time, It has been a great mystery how electricity appears in the atmosphere. But, recent research says that atmospheric water vapor can turn into electrical charge. They are calling it hygroelectricity which means humid electricity.Now, it is realized that hygroelectricity is one kind of static electricity which appears on water droplets and can be moved from droplets to small dust particles. It is a common phenomenon in the earth's atmosphere. Hygroelectric charge exists in thunderstorms volcanic eruptions and some  dust storms which creates lightning. Once, scientists believed that water droplets in the atmosphere were electrically neutral and remain same even after coming into contact with the electrical charges on dust particles and droplets of other liquids. But, recent research says that an electrical charge can be picked up by water in the atmosphere indeed.

Scientists had been charmed by the idea of harnessing the power of thunderstorms for long time. After laborat…

Green Furnace

What is Green Furnace?
Thefurnace which uses renewable sources like natural fuel for their operation is called green furnace. Typically, a green furnace uses olive pits, nut shells, wood, wood pellets from forest residues or surplus industries etc. Green furnace is fed by bio fuel which is more cost effective than conventional fuels like diesel, propane etc. Moreover, due to stability of the price of bio fuel, uses of green furnaces are rapidly increasing in order to generate heat in any home heating system.
Biodiesel is profitable due to it's high calorific value per unit weight. It appears as a form of renewable energy and contributes to protect our environment and energy sources of this planet. If we compare it with fossil fuels, we will observe that one kilogram of pellets contains half the calorific value than a liter of diesel. That means, in order to produce same amount of energy like one liter of diesel, two kilos of pellet or olive stones are required.

Hydroelectric Power

What is Hydroelectric Power?
Hydroelectric power is the technology of converting the kinetic energy of flowing or falling water into electrical energy.
How does it work?
A dam is constructed where there is a big river or a natural lake in a valley. Water is reserved in the reservoir of the dam. There is the water intake near the bottom of the dam. Dam creates pressure so that water can produce more electrical power. Gravitational potential energy stored in the water and this energy is utilized to rotate turbines of generators in order to generate power. These turbines are constructed within tunnels in the dam wall.
With great pressure, water flows inside these tunnels and helps to rotate these turbines. Water can provide huge pressure due to the great height at which is kept in the dam. If the difference of height between the water levels and the water where it flows is very large, then there is the possibility to gain more power out of the water for its greater potential energy. This dif…
