wind energy for $18 million

Bay City will purchase a chunk of its electric power from a Gratiot County wind-turbine farm.

The Bay City Commission on Monday, Aug. 19, voted 7-2 to buy $18 million in electricity generated by the Beebe Community Wind Farm near Ithaca during the next 20 years.

Bay City Electric, Light & Power must comply with a state mandate to provide at least 10 percent of its electricity from renewable energy sources by 2015. The utility has 20,200 customers.

Phil Newton, the city’s electric utility director, has called the contract and its accompanying price a good deal because the cost is lower than he’s seen from other wind developers.

Other communities have already purchased Beebe’s wind farm energy include Holland. The West Michigan community joined four other member utilities of the Michigan Public Power Agency earlier this year in purchasing 26.4 megawatts of power from Beebe.

Bay City’s agreement would be to purchase 4.8 megawatts through the MPPA, a supply agency the city and other smaller municipalities belong to as a group. The initial year will cost Bay City about $45 a megawatt hour, for a total of $700,000.

Commissioners Elizabeth Peters and Chad Sibley protested the length of the agreement. Peters wanted to see an opt-out clause in the contract.

“Energy prices are going to go down,” Sibley said. “At this point, locking (the city) into a 20-year commitment might not be in our best interest.”

Newton previously said Bay City’s 2013 average cost to purchase power was $59 a megawatt hour. Landfill gases run at $85 a megawatt hour and coal-based power costs the city about $54 per megawatt hour, he said.

The cost of the wind-turbine energy increases during the contract’s 20-year term, rising to about $72 per megawatt hour in the final year.

Workers at Siemens Energy, a plant in Hutchinson, will build portions of wind turbines for a project in the northwest United States.

Siemens has an order from Portland General Electric company, a public utility in Oregon.

Hutchinson workers will build the nacelles and hubs for 116 wind turbines. Crews will start installing the wind turbines in 2014. Once the project is completed, it’s expected to generate enough power for 84,000 households.

With a diameter of only 11 mm

The Optoelectronics Company, a leading global manufacturer of innovative optoelectronic components and distributor of OCLARO (Opnext) laser diodes and Panasonic glass lenses, has launched another innovative and cost-effective range of laser diode modules optimised for compact integration into OEM applications where size is critical.

With a diameter of only 11 mm, the modules are ergonomically designed with a small form factor for integration into a wide range of applications such as industrial and medical alignment, low level laser therapy, inspection and sensing where a tiny package is essential to fit into very compact spaces.

This new range of laser diode modules combines a high performance OCLARO (Opnext) laser diode with externally adjustable optics, a Panasonic aspherical glass lens, sophisticated electronics and rugged modular anodised aluminium housing to provide a reliable, energy-efficient and precise laser source for OEMs, end-users and systems integrators. A key feature is the brass lens holder which enables smoother, more accurate focussing by using a finer pitched thread.

“As applications get more sophisticated and devices get smaller, these laser modules are a perfect solution for OEMs to design in where space is at a premium”, commented Tony Pope, Managing Director, the Optoelectronics Company. “Combining high performance with energy efficiency, they require less power, generate less heat, have longer lifetimes and fit into smaller spaces than other laser sources” he added.

The CW lasers produce a high-quality elliptical beam at 5 visible and infrared lasing wavelengths, (635 nm, 639 nm, 660 nm, 830 nm and 852 nm), and offer a combination of low noise and output stability with powers of up to 75 mW. For easy identification they can be supplied with coloured end caps or customer specified engraving on the rear sleeve. Mechanical dimensions are 11 mm diameter x 49 mm length.

With an operating voltage of 3 – 6V DC and a broad ambient temperature operating range from -10 degrees C to +50 degrees C, the modules are also static, surge and reverse-polarity protected and RoHS compliant. Electrical connections are made via 300 mm external flying leads.

Custom lasing wavelengths, from 405 nm to 852 nm, and power options are available on request. Both standard and custom configurations provide OEMs, end-users and systems integrators with complete cost-effective laser solutions.

NextFab Studio hosts prototyping how-to during Philly Tech Week

NextFab Studio in South Philadelphia hosted “Product Prototyping in 60 Minutes”  for 30 engineers, entrepreneurs and artists interested in creating products using the advanced technology available at the studio.

NextFab staffers presented participants with the prototyping steps using a digital house number design, then demonstrated how the product was constructed using the studio’s equipment, including various software programs, a wood-carving ShopBot, a stone cutting Waterjet machine and the Arduino microcontroller.

The event was NextFab’s first prototyping demo and part of Philly Tech Week.

NextFab’s president and founder Evan Malone worries about the loss of manufacturing in the US and wants to show that advanced computer-controlled machines can spur innovation. He said he hopes that the event will show people interested in these technologies the thought process behind turning an idea into a product, and also a few of the pitfalls they are likely to encounter along the way.

“People get excited about an idea and rush in without considering whether the direction they’re headed in is a good one for their ends goal,” said Malone, who explained paying attention to excitement-killers like financing, legal issues and marketability early on can mean success for product creators.

The studio operates like a fitness gym. Members can use NextFab’s equipment, take classes or receive assistance from trained staff members. Biomedical engineering student Melissa Stagnl joined NextFab to learn more about electronic and mechanical programming. “I’m interested in creating a sleep mask that will help with lucid dreaming,” said Stagnl.

Software programmer George Alexander is considering membership and was impressed with the studio’s 3D printing machines and laser cutters.  The prototyping presentation gave Alexander a concrete idea of how the South Philadelphia studio could assist him in creating the jewelry he hopes to make. “The amount of activity that there is in the rapid prototyping and 3D printing area, lots going on in the world, and Philadelphia, this is really where it’s at.”

Today, the pressures faced by PPM center largely on customers seeking offshore solutions, typically from China, Malaysia, and other low-cost areas of the world. As a result, the company has created a niche for machining high-end medical components that, “no one else wants to cut, because it is just not profitable for them,” John says.

He goes on and describes PPM’s manufacturing style as probably a little different, positively attacking CAD models in Pro-Engineer, and then generating our machine code in the same CAD package, returning seamlessly what the client ordered from solid geometry to the reality of actual products manufactured exactly to specification.

“Using Haas technology, we get greedy,” John notes. “We utilize a fourth-axis rotary head to machine four sides of the workpiece with one fixture, and then we flip it, and we are done in two operations, before it goes into our finishing department for deburring.”

Typical materials processed on the Haas machines include 17/4 stainless steel, 400- and 300-series stainless steel, titanium, cobalt chrome, and PEEK (polyether ether ketone). In terms of the latter, PPM has just secured its first order for PEEK, and production of these parts will be on Haas technology.

“We are a no-debt operation – we buy our equipment, pay it off, and move on,” John explains. “The Haas machines are particularly good for us, as is the price structure. The machines we acquired were not $500,000, as some makes; they were a lot less, so we had the means to bring them in as needed, and we could own them outright. In addition, for the size of product that we manufacture, the machining envelopes and tables are just the right size, and the machines have no problem holding the close tolerances our parts require.”

John and his family understand fully the importance of the parts they are making, the difference they can make to a recipient’s life, and the need to pay close attention to specifications and quality.

Turf-cutters issue warning to Deenihan

South Galway turf-cutters have warning that any repeat of last year’s siege at Clonmoylan Bog near Woodford may not end peacefully.

Six representatives from turf cutting organisations, including bog owners from Clonmoylan, Barroughter and Ardraigue Bog Action group, met with Minister for Arts, Heritage and the Gaeltacht, Mr Jimmy Deenihan on Sunday evening in Limerick and told him that they would be resuming the cutting of turf on protected bogs in ten weeks’ time.

Their return to the raised bogs, designated as Special Areas of Conservation (SAC) under the EU Habitats Directive, comes despite the Minister’s revelation that the Government will issue fresh contracts to survey the 53 SAC bogs nationwide.

In a statement from the Department of Arts, Heritage and the Gaeltacht, a spokesperson said that Minister Deenihan “has always made clear his availability to meet with turf cutters and their representatives to discuss the issues, including compensation and relocation, which arise from the protection of raised bog habitats”.

However, Mr Dermot Moran of the Bog Action Group, said turf-cutters were “hoarse” from telling the Minister that they would not be relocated. He accused the Department of Arts, Heritage and the Gaeltacht of “foot-dragging” on the issue.

The six turf cutters met with Minister Deenihan at the Strand Hotel in Limerick, but requested that Mr Seamus Boland, chairman of the Peatlands Council, remain outside of the meeting on the grounds that turf-cutters were not adequately represented on the council.

Mr Moran said turf-cutters would have missed out on last year’s turf-cutting if they had heeded the Minister’s advice and would miss this year’s if they awaited the outcome of fresh consultations.

He said that he was hopeful even more people would be cutting turf this year and predicted that, weather permitting, cutting would begin in April.

Among the issues raised by the turf cutters with Minister Deenihan was a request for compensation for damage done to a turf-cutting machine during the ‘Siege of Clonmoylan’ in June last year.

The machinery, the property of a Mr Francis Donohue, was set on fire during a stand-off between turf-cutters and members of An Garda Síochána and the National Parks and Wildlife Service (NPWS) and Mr Moran said the Bog Action Group may have to consider legal action to recoup the cost of the damage.

Mr Moran said the turf-cutters told the minister that such tactics would not succeed and warned that a repeat of the June stand-off may not end as peacefully.

“They [turf-cutters] will be more fired up than the last time. That siege ended peacefully; it could very easily go the other way,” said Mr Moran.

Machine Tools and Cutting Tools to Global Market

Mitsubishi Heavy Industries, Ltd. (MHI) is taking an important step to intensify its proposal-based marketing of machine tools and cutting tools to the world market through a new approach collaborating with Federal Broach Holdings, LLC, a company MHI acquired this April.

Going forward, MHI will aggressively explore demand from customers seeking enhanced production efficiency and machining accuracy in the automotive and aircraft industries, and will support them through machining systems combining the technologies of the two companies. As part of this initiative, MHI will present its machine tools and cutting tools at the International Manufacturing Technology Show (IMTS) 2012 to take place September 10 through 15 in Chicago, Illinois, in collaboration with Federal Broach, to demonstrate their high-level solutions for diverse needs in a broad range of fields.

In pursuing synergy effects from the integration of its business operations with those of Federal Broach, MHI looks to explore global markets leveraging the two companies’ respective business bases. Major targets are automotive-related industries and manufacturers of jet engines and turbines that use the broaches and broach machines produced by Federal Broach, as well as users of automotive, construction and industrial machinery in the Asian markets, where MHI is in a position of solid strength.

Together the two companies will offer potential customers proposals on various machine tools and cutting tools, including gear cutting machinery, as well as know-how in selecting optimum machining technology. This approach is designed to help customers extend their range of machining process choices according to their specific needs: for example, enhancement of mass-production capability, greater machining accuracy or cost reductions. In addition, integration of the two companies’ production and production-control technologies will enable shorter delivery periods and provision of finely tuned servicing and support leveraging their respective operating bases.

At IMTS 2012 MHI and Federal Broach will jointly propose systems capable for high-speed precision machining of workpieces, including gears. MHI will present its “MVR30,” a double-column 5-face milling machine, and two gear machines: the “SE25A,” a dry-cut gear shaping machine, and the “ZE40A,” a universal gear grinding machine capable of numerically controlled (NC) high-precision machining of post-heat treatment gears. The MVR30 provides highly accurate, high-speed machining and has an abundant delivery track record, mainly for machining of metallic molds for automobile parts and parts used in various large-size machines.

The ZE40A is capable of accommodating both generating grinding and profile grinding and can be applied to machining of diverse workpieces. Federal Broach will exhibit various cutting tools: helical broaches used to process the inner teeth of helical gears, which are found in the automatic transmission gears of motor vehicles, and “pine tree” type broaches, which are used primarily for machining grooves that mate blades and turbine discs in the fabrication of jet engines and turbines for power generation plants.
