Abstract India is the world’s fourth largest economy and has a fast growing energy market. India’s current power capacity is 30% short of demand. Coal and petroleum are the primary sources of energy. High ash content in Indian coal and inefficient combustion technologies contribute to India’s emission of air particulate matter and other trace gases, …
Want to live and use energy on Mars? Why not?
The problem of energy accessibility and production on Mars is one of the three main challenges for the upcoming colonisation of the red planet. The energetic potential on its turn is mainly dependent on the astrophysical characteristics of the planet. A short insight into the Mars environment is thus the compulsory introduction to the problem …
Fire Protection Measures
The measures to mitigate or lessen fire hazards are normally called “fire protection measures”. The National Fire Protection Association NFPA (U.S. organization charged with creating and maintaining minimum standards and requirements for fire prevention and suppression activities, training, and equipment, as well as other life-safety codes and standards) standards and local building fire codes set …
How much for the geothermal energy? Impacts, hm?
Economics Geothermal power requires no fuel, and is therefore immune to fuel cost fluctuations, but capital costs tend to be high. Drilling accounts for over half the costs, and exploration of deep resources entails significant risks. A typical well doublet in Nevada can support 4.5 megawatt (MW) of electricity generation and costs about $10 million …
Thumbs down to the nuclear energy
Although for decades the arguments against nuclear power have been –and still are- strong and valid, there is an increasing group of nuclear companies supported by scientists and politicians, who say we need nuclear power to fight climate change and to be independent. They also claim that all the problems associated with nuclear power are …
Technology future – The cost of inaction
Without new thinking on technology intervention, the future looks bleak. Unless the role of technology in the global economy is reconsidered, we risk becoming powerless to feed a growing population, combat climate change, meet energy demands and adapt to dwindling natural resources. The consequences could be disastrous – increased pollution, poorer living conditions, power struggles …
Please, help brave Japan people!
As you already know, Japan is suffering from the greatest disaster since world war 2. A tremendous earthquake, a huge tsunami and now radiation leaks have caused untold damage in this marvelous country of honest, industrious people. I am really amazed at and greatly impressed by the honesty, tenacity, self discipline, perseverance, and self respect …
Building a Sustainable Future in a Technology – Dependent World
For thousands of years, humanity developed on the back of technology innovation. Through our inventiveness, we have thrown off the shackles of evolution and forged our own destiny. The process has not been a smooth one – disease, pollution and modern warfare are just some of the less attractive by-products of innovation. Nevertheless, most people …
Renewables And The Impact On Environment
Alternative energy sources, especially with regard to air emissions. The likely life-cycle emissions (taking into account fuel cultivation, harvesting, collection, transportation and processing, as well as power plant construction, operation and decommissioning) from main renewable energy technologies and conventional electricity generation are shown in Tables 2 and 3. The results are purely indicative but show …
