November 22, 2016: Recycling and reusing have become very useful method for creating energy and electricity. They are not only environment-friendly but also easily available energies. We have seen cow dung being used as important energy resource for producing biogas. Recently a Mexican scientist Gabrial Luna-Sandoval has come up with a new invention whereby human urine can be used for generating electricity.

Humans pee about one and half liters a day. Gabrial’s new machine processes them and the urine gets turned into biogas which serves as a household heater to take a hot shower or can be used for cooking as well. The machine uses electrolysis and hydrogen in urine to produce biogas. This creates electricity or replaces natural gas.

According to Dr. Gabrial “15 ml urine is enough considering that we produce 1.4 liters of urine and if there are 3-4 members in family then the family can pay enough to cook”. This method of electricity generation can have far reaching consequences, it can be used for future calling use in Mars.

Even the water used for energy will not go waste, as the filtered water can be used for drinking purpose as well. These are the certain possibilities that it has.

British researchers, on the other hand, have developed microbial fuel cells that use live bacteria that feed on to inter-generate electricity.

Argentina is not lagging behind in generating renewable energy volunteers from Sumando Inerhias are recycling the trash to create solar energy. This will help in running water power heaters. This will be a great source of relaxation for communities that lack electricity and water. Apart from creating solar energy, they are also teaching them about recycling. Thus it’s a two-fold benefit scheme for the community, as it can not only use the energy but can even actively take part in its generation.

A local resident Angel Guelari says that ‘these are things that we throw away and they contaminate the environment, we can use them for practical things like having water in the house it’s good to recycle.’ Sumando Inerhias saw an increase in its number of volunteers over the years and they hope to build solar panels for three thousand families per year now, as reported by VOA news from Washington DC.

Renewable energy is not only cleaner but also safer and less polluting technique in the generation of energy. The shortage of resources can be curbed by switching over to a renewable form of energy.  Community participation plays an important role in these forms of energy. It helps in creating awareness and judicious use of resources.

Old Dusty Kilogram Swapped for Something More Stable: Scientists

It has taken years of work to fine-tune the new definition to ensure the switchover will be smooth.

After years of nursing a sometimes dusty cylinder of metal in a vault outside Paris as the global reference for modern mass, scientists are updating the definition of the kilogram.

Just as the redefinition of the second in 1967 helped to ease communication across the world via technologies like GPS and the internet, experts say the change in the kilogram will be better for technology, retail and health — though it probably won’t change the price of fish much.

The kilogram has been defined since 1889 by a shiny piece of platinum-iridium held in Paris. All modern mass measurements are traceable back to it — from micrograms of pharmaceutical medicines to kilos of apples and pears and tons of steel or cement.

The problem is, the “international prototype kilogram” doesn’t always weigh the same. Even inside its three glass bell jars, it gets dusty and dirty, and is affected by the atmosphere. Sometimes, it really needs a wash.

“We live in a modern world. There are pollutants in the atmosphere that can stick to the mass,” said Ian Robinson, a specialist in the engineering, materials and electrical science department at Britain’s National Physical Laboratory.

“So when you just get it out of the vault, it’s slightly dirty. But the whole process of cleaning or handling or using the mass can change its mass. So it’s not the best way, perhaps, of defining mass.”

What’s needed is something more constant.

So, at the end of a week-long meeting in the Palace of Versailles, Paris, the world’s leading measurement aficionados at the International Bureau of Weights and Measures will vote Friday to make an “electronic kilogram” the new baseline measure of mass.

Just as the meter — once the length of a bar of platinum-iridium, also kept in Paris — is now defined by the constant speed of light in a vacuum, so a kilogram will be defined by a tiny but immutable fundamental value called the “Planck constant.”

The new definition involves an apparatus called the Kibble balance, which makes use of the constant to measure the mass of an object using a precisely measured electromagnetic force.

“In the present system, you have to relate small masses to large masses by subdivision. That’s very difficult — and the uncertainties build up very, very quickly,” Robinson said.

“One of the things this [new] technique allows us to do is to actually measure mass directly at whatever scale we like, and that’s a big step forward.”

He said it had taken years of work to fine-tune the new definition to ensure the switchover will be smooth.

But while the extra accuracy will be a boon to scientists, Robinson said that, for the average consumer buying flour or bananas, “there will be absolutely no change whatsoever.” (VOA)
