Energy Opportunity

Energy opportunity

Many African states have committed themselves to realising milestone development goals in the near future. Development is measured by using an array of indicators, these include having clean tap water, tar roads, and electricity amongst other things. When a vast majority of a country’s population has unhindered access to these amenities, it can be said that development is on an upward trajectory. The move towards development presents numerous opportunities for new technologies and renewable energy to be introduced in these countries. For instance, there are still many communities without electricity and electric power. An article in the Economist reports that… read more

Producing Power From Food Waste

Food waste to energy

In countries like the US, food wastage has become as serious a problem as pollution. In 2010 more than 35 million tons of food was wasted in the U.S making up 14% of total municipal solid waste. More than 30 million tons of items that are not recyclable are thrown away creating landfill. Both the economy and the environment are affected by food wastage. Households spend a geat deal of their budget on food, and any wastage is a cost to the budget. Efficient food purchasing, optimal storage, and careful preparation can save you money. Not only on a household level,… read more

Power From The Body

Power from the body

Obtaining power from the human body may sound like a crazy idea, but scientists have started to take this idea seriously. There are various ways one can obtain power from the body such as heat, body movement and vibrations metabolism. One obvious form of energy harvesting is using well known piezo-electricity technology, which means converting human movements and vibrations into electricity. Researchers from the University of Michigan have developed a prototype using piezoelectricty to charge pacemakers installed in human hearts. Generally, pacemakers are introduced to do the work of the heart which has become weak but patients face many and regular… read more

Hungry Electronics

Power consumption

Modern electronic gadgets have jaw-dropping functions making human life simpler in several ways. Their smartness can be seen in many ways such as speed, functionality, multitasking capabilities etc. but one main thing modern electronics manage well is power usage. Modern devices are not only highly functional but they are extremely power conscious. It has become mandatory for devices like tablets and notebooks to manage power cleverly, just like an electric car that goes to an idle state and consumes less power. Older gadgets lack this power-management capability as they only have two states – either On or Off. “Off is… read more

Thermo Electric Uses

power from car tailpipe

We put lot of sweat and engineering to produce energy which runs our lives, but as much as two thirds of this energy gets dissipated as waste, particularly in the form of heat. Recent reports show that a new material can bridge the gap between energy produced and wastage through heat. An international team of researchers has developed a new material which generates charges from the temperature variations across its two ends. These thermo electric materials, when commercialised, will find their place in a variety of applications. Let’s take a simple example. A car drinks a lot of energy to… read more

Cooling Down The IT

Inside a data centre

Computers have virtually fashioned another world for humans, with recent encroachment like cloud computing, computers have become another home for humans giving them utmost services with a very little effort, but there is a serious problem with so called “data centres” which are volcanoes inside a room, it has been found in a recent research that more than half of energy consumed by data centres are used to cool down millions of processors inside boxes. This heightened problem has caught the attention of various design firms whose major job, now is to work in reducing the power consumed to cooling… read more
