We also reported on a Stanford University study that calculated that there's enough wind near shore and over land combined to produce at least half the world's power demand by 2030, using what the researchers say is the most sophisticated climate model ever created.
As the installed base of turbines has grown, manufacturers view operation and maintenance services as an increasingly important revenue stream. That's been especially true during the industry’s current slowdown. One reason for the contract price drops has been better service performance of the turbines themselves. Another is more competitive bidding among turbine manufacturers for service contracts. It's interesting to note that the period covered by the analysis coincides approximately with the worldwide financial downturn, which put the brakes on growth in many industries and heated up competition.
One reflection of turbines' improved performance and improvements in wind farm management is the fact that the contracts' average availability guarantees reached 96.9 percent. The report noted that such guarantees for actual energy production are becoming more common.
The participants in this first Operations and Maintenance Price Index expect contract pricing to remain relatively stable until at least 2015, according to the report. The most competitive pricing of all markets occurred in the US.
In the future, the Index will be updated twice a year.
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.
Instead of sifting through huge amounts of technical data looking for answers to assembly problems, engineers can now benefit from 3M's new initiative -- 3M Assembly Solutions. The company has organized its wealth of adhesive and tape solutions into six typical application areas, making it easier to find the best products to solve their real-world assembly and bonding problems.
Many of the materials in this slideshow are resins or elastomers, plus reinforced materials, styrenics, and PLA masterbatches. Applications range from automotive and aerospace to industrial, consumer electronics and wearables, consumer goods, medical and healthcare, as well as sporting goods, and materials for protecting food and beverages.
Engineers trying to keep track of the ever-ballooning number of materials and machines for additive manufacturing and 3D printing now have some relief: a free searchable database with more than 350 machines and 450 different materials.
At JEC Europe Dow Automotive introduced a new ultra-fast, under-60-second molding cycle time for its commercial-grade VORAFORCE 5300 epoxy resin matrix for carbon composites. It's aimed at high-volume automotive manufacturing.
