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.
The new composites manufacturing innovation center is intended to be a source of grand challenges for industry, like the kind that got us to the moon under JFK. These aren't the words its new CEO Craig Blue used, but that's the idea and the vision behind the Institute for Advanced Composites Manufacturing Innovation (IACMI).
The 100% solar-powered airplane Solar Impulse 2 is prepping for its upcoming flight, becoming the first plane to fly around the world without using fuel. It's able to do so because of above-average performance by all of the technologies that go into it, especially materials.
As the 3D printing and overall additive manufacturing ecosystem grows, standards and guidelines from standards bodies and government organizations are increasing. Multiple players with multiple needs are also driving the role of 3DP and AM as enabling technologies for distributed manufacturing.
A growing though not-so-obvious role for 3D printing, 4D printing, and overall additive manufacturing is their use in fabricating new materials and enabling new or improved manufacturing and assembly processes. Individual engineers, OEMs, university labs, and others are reinventing the technology to suit their own needs.
For vehicles to meet the 2025 Corporate Average Fuel Economy (CAFE) standards, three things must happen: customers must look beyond the data sheet and engage materials supplier earlier, and new integrated multi-materials are needed to make step-change improvements.
