@Debera – yes wind turbines could only be used where there is wind, but my opinion is we should use multiple methods to generate renewable energy. There might be an instance where we don't have wind but have ample sun light; we could use solar panels to make use of the sunlight we waste.
@William – yes as you said wind is a free resource (for now) we need to make the maximum use of the natural resources we have. It's only the initial setup cost and may be a small service cost once in 6 months.
@Rob – yes you have a point, some don't get wind for most of the days, and this is when we should use a combination of solar panels and wind turbines to balance off. Do you think this will solve the problem?
@rainmaking - I am not much familiar on the sizes and the power the wind turbine generates. Would you know the size of a 70kW turbine? Can we not make it small and use a step up transformer to increase the power.
@pnadams – Well explained how wind turbines evolved, this is basically the same methods that was use sometime back, the only difference is now we use modern technology to make it small and harvest more energy.
@tekochip – Yes turbines have many moving parts, but I don't think it would make much noise other than the noise of the wind. I think that because the wind turbine generate energy not consumes it. Any engine that consumes energy will usually make sound when it burns the energy,
In a bid to boost the viability of lithium-based electric car batteries, a team at Lawrence Berkeley National Laboratory has developed a chemistry that could possibly double an EV’s driving range while cutting its battery cost in half.
Using Siemens NX software, a team of engineering students from the University of Michigan built an electric vehicle and raced in the 2013 Bridgestone World Solar Challenge. One of those students blogged for Design News throughout the race.
Robots that walk have come a long way from simple barebones walking machines or pairs of legs without an upper body and head. Much of the research these days focuses on making more humanoid robots. But they are not all created equal.
For industrial control applications, or even a simple assembly line, that machine can go almost 24/7 without a break. But what happens when the task is a little more complex? That’s where the “smart” machine would come in. The smart machine is one that has some simple (or complex in some cases) processing capability to be able to adapt to changing conditions. Such machines are suited for a host of applications, including automotive, aerospace, defense, medical, computers and electronics, telecommunications, consumer goods, and so on. This discussion will examine what’s possible with smart machines, and what tradeoffs need to be made to implement such a solution.
