The decreasing power requirements of consumer electronics combined with an increasing environmental mindedness of consumers and the increasing use of portable electronic products has set the opportunities for human power as a viable alternative to batteries. No use of batteries means an environmental benefit as well as a consumer benefit. It will lead to new product concepts offering real porta...

I never thought I’d favor nuclear power. But here it is: I believe nuclear energy is our last best chance to stem the tide of climate change. Time is running out for reversing greenhouse gas emissions and transitioning from the fossil fuel age. Nuclear power must occupy a larger share of our energy mix and replace coal-fired power plants. For energy policy, I think “near-term” decisions should ...

In this paper, a multi-objective optimization method is implemented by using of genetic algorithm techniques in order to determine optimum configuration of solar chimney power plant. The objective function which is simultaneously considered in the analysis is output power of the plant. Output power of the system is maximized. Design parameters of the considered plant include collector radius (R...
