Wind Power Operating, Maintenance Costs Drop 38 Percent
The costs of wind power are falling, not only for turbine cost and performance, but also for operating and maintaining wind farms. Shown here, Siemens service engineers work in a wind turbine's gondola. (Source: Siemens)
Ann, that is an interesting point you raise. As costs come down, the payback period will shorten.
Actually, I was visiting a cousin who has a farm in central Illinois. As we were driving to lunch one day I noticed the one wind turbine in the area. On asking him about it, he said the problem was the payback period on them. I guess some people get paid rent to allow tuebines to be sited on their land (like farming rents) while others get involved in the financing of the turbines. Even for turnines to power the farm itself, he said that these are way too expensive to be worth it. These guys are very practical and hard headed. If it does not make sense they don't do it. They are also generally well educated, informed and tech savvy these days. They have to be.
On a related issue, I asked him about corn stalks for ethanol production. They were all still laying around his farm and all the others in the area. I guess the problem is that they have to bundled to be sold to the processors. As long as crop prices are so high because of international demand it will not be worth the extra time and effort for the farmer to do this.
Materials and assembly methods on exhibit at next week's MD&M West and other co-located shows will include some materials you should see, as well as several new and improved processes. Here's a sampling of what you can expect.
The Food & Drug Administration has approved a 3D-printed, titanium, cranial/craniofacial patient-specific plate implant for use in the US. The implant is 3D printed using Arcam's electron beam melting (EBM) process.
The upcoming MD&M West and co-located shows in Anaheim next month will be host to a huge variety of technologies and special events like the Golden Mousetrap Awards. Here are five reasons for medtech professionals to attend.
Many of the new 3D printers and printing technologies in this slideshow are breaking some boundaries, whether it's build speed, new material types, density and quality of 3D-printed circuit board layers, or build volume in a hybrid printer. We also give some recent market statistics.
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.
