facts about science

Recently, researchers are concentrating on biofuel that is obtained from algae as this might prove important in the near future seeing that it replaces human usage of fossil fuels. The advantage of this biofuel is that it is environmental friendly. They help curb the effects of carbon that has been released to the environment. But this would require large scale usage of this fuel around the world.

One of the main drawbacks of biofuel comes when it is being manufactured. The first difficulty comes when the algae are separated from the growth medium. The other is that the algae need to be dried before the fuel can be obtained. This process of drying is very crucial in the harvesting of biofuel.

Decomposition process is responsible for the formation of fossil fuels. This type of decompositions can be classified as anaerobic. This process takes million of years for organisms to decompose and form fossil fuels. Fossil fuels can be categorized into coal, oil and natural gas. These fossil fuels constitute a huge percentage of the world’s energy production. Read on to know more significant facts about fossil fuels.

Random Facts about Fossil Fuel

• Crude oil has many characteristics one of them s that t has a pungent smell. Since it is normally located underground, exploration and study of an area has to be done to determine viability of mining the oil.

Biomass can be defined as any living matter like animal and plants. This form of energy originally comes from the sun. Plants convert the energy from the sun to biomass energy by the photosynthesis.

Interesting Facts about Biomass Energy

• This form of energy is renewable and is capable of producing electricity. It is renewable because plants can always be grown again to produce more biomass. One way of utilizing biomass is done by burning for example garbage to produce electric power.

• Biogas is also is a product of biomass. Biogas is mainly used for heating purposes

Rainforests may be beautiful but they are in danger of being cut down. Rainforests layers hold most of the world’s diverse wildlife and if they are destroyed, that will eliminate the animals as well. Read on and find out more interesting rainforests facts.

Many people might not know this but there are rainforests even in Alaska. The only place that doesn’t have rainforests is Antarctica.

Rainforests are essential to human life. They have a lot of trees and trees are necessary for us to breathe clean air. They also help us to have clean water as well.

Many scientists claim that hydrogen will soon become the energy of the future. It might even replace fossil fuel, which are today’s main energy sources. With the current technology, hydrogen gas is obtained from splitting methane. This method cannot be used in large scale because it produces harmful products like carbon dioxide.

But some scientists have developed a promising method of producing hydrogen. This process is called electrolysis. Electrolysis is the process of splitting water molecules into hydrogen atoms and oxygen atoms. This form of electrolysis is specifically called high-temperature electrolysis.

Researchers are currently working on full scale plants that are capable to produce around 2.5 kgs of hydrogen gas every second. This is a big step since in comparison 1kg of hydrogen gas is capable of producing the same energy as one gallon of gasoline.

Tidal energy is as result of the sun’s and moon’s gravity effects on earth. With this form of energy, electricity is produced by the use of ocean water. This energy is produced when the level of the oceans changes (i.e. tides). More interesting facts about tidal energy will be brought to you by these science facts. Read on and enjoy.

Significant Tidal Energy Facts

• Tidal energy can be traced back to ancient times. It was used in places like Spain and Britain, in the form tide mills. It involved operating a water wheel. These water wheels were rotated using water that flowed via sluices.

For centuries, people have been searching for ways to cool down from the hot humid heat. Before the convenience of air conditioning was invented, ancient peoples had to haul loads of ice to their homes and use old fashioned machines or even slaves to fan themselves off. Which we know is not the best way to cool down. It still can be very humid air and feel sticky around you.

Once there started to be more technological advances, textile factories in the 1700s started to attempt at inventing an air conditioning system. In England, they created a system that could heat up their warehouse and also help to ventilate the air. The problem with this though is that it got too hot and that compromised the workers’ health.

Light is an electromagnetic wave that moves at a speed of 300,000 kilometers per second in a complete vacuum. Currently nothing can move faster than the speed of light. Read on to learn more interesting facts about light.

Light would take around 1.3 second to move from the moon to the earth. At this speed, one could reach the nearest star outside the solar system in around 4.5 years. Still, at this speed crossing the galaxy on its width would take an astounding 100,000 years.

Since distances in space are great, scientist use a unit called a light year to measure distances in space. One light year can be defined as the distance light would travel in a whole year. A light year is equivalent to 6 trillion miles.

The year was 1948, when the 1st computer (nicknamed “Baby”) was made. The computer contained a mere 1024 bits (1kb) of data. Before this computer came into the scene, computers had to undergo rewiring each time they needed to be programmed for another task.  Electronic reprogramming was used in this computer.

Fun Facts about Laptops and Computers for Kids

• Baby could run an incredible 700 instructions every second using only 1,024 bits of memory. Even with this low processing power, Baby was considered a computer.

Coal which is mainly made of carbon can be categorized as a fossil fuel. It is the chief form of energy used to produce electricity. The main disadvantage of coal energy is that it is the biggest source of carbon emissions to the atmosphere. Though, coal is mainly carbon it can have other elements like sulfur nitrogen, and hydrogen in varying concentrations. More facts about coal energy as you read on.

Interesting Coal energy facts

• This form of energy has been present since ancient times. That is around 3000-2000 BC. Coal has significantly played a role in the growth and development of China and India. This is because it is cheap and is found in many parts of the world.
