Simple Things

Innovation in developing nations

Science has always helped mankind with all it can to make life simpler and healthier. Revolutions happen around the clock from fountain pens to rockets helping humans in one way or the other. Certain innovations are made accidently while some are invented to meet problems but in most of cases they don’t reach the common man quickly or are too pricey for them to afford. Simple technology and easy-to-use innovations are better in places where energy, education and materials are plentiful.  In developing countries where resources are scarce  it could even be as simple as developing a water bottle but it makes a… read more

Cheap Renewable Energy

Power inverter research

At Indiana University – Purdue University Indianapolis an assistant professor, Afshin Izadian, has invented a new class of power inverter that could help put cheaper and more efficient renewable energy products on the market. The power inverter that he created employs just a single switching transistor and generates infinite-level voltages. Power inverters are the main technology of several renewable energy technologies. Solar power, battery storage, electric vehicles, motor drives and manufacturing robots all use inverters to generate AC power efficiently. The current inverters with multiple switching transistors generate limited voltage levels, are heavy, and require filters to reduce the harmful effects… 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

A Big Deal

Offshore windfarms

In the upcoming presidential election, jobs are still a major issue to voters, and the candidates are expected to present plans to increase job growth and sustainability. Recently released jobs reports indicated unemployment dropped to 7.8%, though the people who exist on the fringes claimed it was a conspiracy—unemployment could not be that low. Let us assume the number is, in fact, real, and the job climate is getting better. “Getting better” doesn’t mean “no longer a concern” though, and there is a proposed development which could generate up to 70,000 jobs and 7,000 megawatts of energy. The Atlantic Wind Connection, funded… read more

Clean Coal Conundrum

Carbon sequestration

The term “clean coal” sounds paradoxical, but it is theoretically clean.Well, if “clean” means “not in the air”. Theoretically, coal can be “clean” in two different ways. Carbon sequestration captures the emissions from burning coal before they exit through the smokestack, and stores them deep underground where they can’t escape. The technology isn’t available for carbon sequestration now, and likely won’t be for decades. Further, the process isn’t economically viable, but if it is a component of a clean energy policy, then its progress will accelerate from additional resources. The other way to have clean coal is to use what’s called a “scrubber”, which… read more

Rooftop Turbines

Rooftop wind turbines

Most wind turbines are placed offshore due to their sheer size and the possibility of dangerous incidents when and if they breakdown. Wind turbines are now being placed on top of buildings.  Rooftop wind turbines include a guard to save from incidents from the blades but questions are normally asked about the efficiency of the turbine and whether or not it is cost worthy. Typically, any device that can save money and energy from natural sources is a favorable incentive. The real issue with rooftop turbines is the cost to install and maintain them.  The regular cost of a rooftop turbine… read more

Solar Industry Stabilization

Solar Industry Stabilization

On the heels of a record-setting 2011 for photovoltaic manufacturing and sales, the 2012 end-market doesn’t look like it will come close to matching those numbers. NPD Solarbuzz, a research, analysis, and consulting firm for photovoltaic products, stated there will be just less than 30 GW of photovoltaic demand in 2012, citing global trade barriers and market consolidation as the main reasons of the decreasing marketplace demand. As a result, the companies which manufacture photovoltaic products that survive the market could be set for big rewards in 2013. Solarbuzz went on to say it believes next year will experience a… read more

Energy Storage Required

Energy storage

It is very easy to forget about the logistics of energy systems when there is so much drama and conflict surrounding the energy sources, but it is imperative that energy storage is not forgotten when a final renewable energy policy is implemented. Producing a vast amount of energy from renewable sources is excellent, but it is generally accepted that a successful renewable energy policy will produce more energy than the demand calls for, which would require storage and preservation if intentions are to not waste the energy. This is not a new concept, nor is it foreign. Refrigerators solved the… read more

Alternative Energy Travel

Electric and hybrid vehicles

It has been predicted that gas-powered vehicles will be replaced by electric and hybrid modes of conveyance within 50 years. This would be a tremendous benefit to our planet, as well as other areas of everyday life impacted by alternative energy transportation. The importance of these ecologically conducive vehicles in today’s automobile research/development cannot be overstated, and here’s why: Health Benefits- Regional pollution will be dramatically reduced when a growing section of the population switches to EV’s (Electric Vehicles) or hybrid automobiles. Carbon emissions can adversely affect personal health if a driver is in or near a vehicle with poor… read more
