@Elizabeth – I think in NY we could have the small wind turbines and solar panels on top of roofs on skyscrapers. Solar panels could also be on streets to light up the street light there by at least contributing something to the power grid.
@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,
Altair has released an update of its HyperWorks computer-aided engineering simulation suite that includes new features focusing on four key areas of product design: performance optimization, lightweight design, lead-time reduction, and new technologies.
At IMTS last week, Stratasys introduced two new multi-materials PolyJet 3D printers, plus a new UV-resistant material for its FDM production 3D printers. They can be used in making jigs and fixtures, as well as prototypes and small runs of production parts.
In a line of ultra-futuristic projects, DARPA is developing a brain microchip that will help heal the bodies and minds of soldiers. A final product is far off, but preliminary chips are already being tested.
Focus on Fundamentals consists of 45-minute on-line classes that cover a host of technologies. You learn without leaving the comfort of your desk. All classes are taught by subject-matter experts and all are archived. So if you can't attend live, attend at your convenience.
