Utility company Southern California Edison (SCE) has confirmed plans to build a massive 909 MW wind farm in Oregon. When completed, the facility will be one of the largest fully permitted wind power sites anywhere in the world.

The installation will be located in Morrow and Gilliam counties in North-Central Oregon, and will consist of 303 3MW wind turbines spread across a 30-mile radius. The project, called Caithness Shepherd’s Flat, will generate around two billion kWh of energy, roughly 10 per cent of SCE’s total alternative energy portfolio.

When finished, the Roscoe site will become one of the world’s largest wind farms, boasting a total of 627 wind turbines capable of powering more than 250,000 of the state’s homes.

If you need a refresher on thin film solar technology, check out two of our previous posts. The important thing to remember here is that thin film solar is lighter than silicon panels, and uses different wavelengths of light.

In May of 2008, Magco Inc. installed 27kW of Unisolar’s triple-junction laminate panels. That’s 4,900 sq ft of thin film goodness. The building contains a warehouse and offices, and it has a metal roof. The solar panels were literally glued to the roof.

Total installation cost: US$215,000 (including inverter and hiring a master electrician)

Energy produced each month provides about 1/3 of Magco’s total needs. That may not seem like a lot, but recall that this includes a warehouse with associated heating/cooling, machinery and equipment. Magco anticipates producing about US$9,000 each year from the panels. So let’s do the math:

Not many bloggers are able to witness the technologies we research and write about. It’s one thing to be able to buy afford a cool “green” gadget (usually not very green), but another to see the many forms of solar, wind, geothermal, etc., which are always changing and developing around the world. So when my employer decided to go solar, you might imagine my excitement.

At the moment I work for Magco Inc., a Tecta America company. Tecta is a national commercial roofing corporation that can install green roofs, solar lighting, and solar panels alongside a variety of traditional roofing systems. This solar project is pretty straight forward: our building has a big, flat roof on top of a hill without any shade. You’d have trouble finding a sunnier spot for solar panels.

I was double delighted when I heard that they ordered thin-film solar! Naturally inquiring minds wanted to know: why and what kind?

There is a little family of asexual plants commonly known as duckweed, and otherwise known in the botanical world as lemnaceae. These smallest flowering plants are lean, lime-green, clean, eating machines. Lemna is the most common of this family, and has quite a profound impact for its size. Each plant has one paper thin leaf the size of the tip of an eraser. They thrive in freshwater lakes, streams, and ponds high in nitrogen, ammonias, and phosphorus. As they feed on these “excess nutrients” the tiny plants help remediate the water on which they live atop.

Though these lime-green plants are tiny, there is no need to call them fragile. They can grow in full sunshine or dense shade, and they endure a challenging range of ph levels. They hibernate during the cold months at the bottom of their watershed and, come May, the plant “springs” up and gets to work cleaning its ecosystem. This tiny plant has been known to cover bodies the size of football fields in just a couple months. It goes unsaid that these tiny soldiers are friend and not foe when it comes to water remediation.

When artist and engineer Viet Ngo established a company back in 1983 called Lemna International that applauds and utilizes the capabilities of these mini soldiers, we weren’t surprised. Ngo, a first-generation Vietnamese immigrant, and his colleagues got a little fame when they designed a carefully engineered art installation in 1990 on Devils Lake, ND. Funded by the EPA, they designed and implemented the beautiful 50 acre, 9 channel, intestine-like system that extracted all detrimental phosphorus, nitrogen, and algae from the wetland before the water reached a bay of Devils Lake. This $50 million project encouraged the group of designers, artists, and engineers to combine the profoundly simple yet complex water remediation technology with other environmental infrastructure problems to clean up the earth. Over 25 years later, the company is managing its success with innovation, consciousness, and integrity.

Lemna International designs environmentally responsible and economical wastewater treatment technologies that naturally clean our polluted waterways. They design for everything form dams to freshwater remediation to drinking water treatment plants, pipelines, and distribution systems. Based in Minneapolis, MN the company has designed and implemented over 300 projects in 16 countries.

The company does not stop at only providing us with clean water. They make sure our water stays clean by removing any harmful waste and either safely putting it in landfills built to international standards, or incinerating it to generate electricity and heat in facilities equipped with air pollution control systems. Their impressive profile of clients ranges from industrial food manufacturers and tire plants to hospitals. They additionally serve a number of cities worldwide.

As the company gained momentum with their patented water remediation technology, they have branched out into additional sectors of environmental infrastructure including transportation, alternative energy, and general infrastructure. Like the lean, lime-green, clean, machines that duckweed are, Lemna International is actively seeking to fix any environmental problem a private or public client might have with an ingenious and unique solution!
