One of the leading voices in the campaign to rescue Lake Erie from dying again is a persistent, thoughtful, dedicated water protector promoting awareness of the Lake’s benefits, supporting lighthouse restoration, fighting resurgent algae and proposed new pollution sources, and seeking funding to restore all of the Great Lakes. She’s an example of the citizen action that has a fighting chance of fending off multiple threats to the Lakes and renewing their beauty and productivity.

An ecologist and an engineer at Michigan State University are working together to create robot fish that can better monitor various factors in aquatic environments.

Combining the brilliance of nature with some top-notch engineering, these two scientists are on to something and getting the funding for it.

The researchers are breaking ground with this and looking to raise water monitoring to another level.

California-based company Cereplast has revealed that it is developing breakthrough technology to transform algae into bioplastics, and predicts that it could replace 50% or more of the petroleum content used in traditional plastic resins.

Cereplast already makes plastic from renewable material such as corn starch, tapioca, wheat and potatoes, but is keen to trumpet the advantages of the new approach.

According to Frederic Scheer, Founder, Chairman and CEO of Cereplast, “Algae-based resins represent an outstanding opportunity for companies across the plastic supply chain to become more environmentally sustainable and reduce the industry’s reliance on oil.”

The researchers further warn that increasing temperatures in this vital, globally-extended ecosystem could “reduce the transfer of primary produced organic matter to higher trophic levels” (e.g., such as those that sustain corals and the many species that use them as habitat), interfere with the global carbon pump, and possibly set up a positive feedback mechanism, further increasing atmospheric carbon dioxide.

Lake Erie, declared dead by the news media in the 1960s because of widespread, repulsive algae blooms, is once again marred, this time by both old and new causes. Some scientists and lake advocates worry that the unsightly algae is a warning of a lake once again in decline.

Tom Bridgeman, a lake scientist with the University of Toledo’s Lake Erie Center, said, “I’ve never seen the water as green as it was this year — and it’s not showing any signs of dying off yet. This is a growing problem.” Increased phosphorus runoff from farms and city streets, coupled with the feeding and excretion habits of non-native mussels introduced through ballast water, is believed to be associated with the resurgent blooms.

The western end of the lake has suffered from a surge in microsystis algae this summer. Bridgeman hypothesizes that in addition to phosphorus, underwater sediment shifts are culpable.

As part of a National Science Foundation grant program to examine cutting edge ways to make nature work for us, a team of scientists at Iowa State University have been awarded $2 million to unravel how some plants and algae can make hydrocarbons and discover if the genes that govern that process might be isolated.

“These plants are capturing solar energy and creating something that’s chemically identical to petroleum,” said Jackie Shanks, Iowa State’s Manley R. Hoppe Professor of Chemical Engineering, in a statement.

The demise of retail giant Filene’s Basement may have a positive effect on proponents of vertical urban farming and algae biofuels alike. Since 2007, the developers of a Filene’s site in downtown Boston have been unable to find funding to move the project forward. But now Höweler + Yoon Architecture and their partner Squared have put forth a proposal to erect a temporary vertical, modular, algae bioreactor high-rise in its place.

Blue-green algae blooms on Minnesota lakes are linked to a dog death and illnesses, and apparently caused by runoff pollution.

The death of a dog after it frolicked in a Minnesota lake plagued with blue-green algae was a sad coda for a late summer in the state. Although no necropsy was done, a spokesperson for the Minnesota Pollution Control Agency said  “the circumstances and manner of death were consistent with exposure to algal toxins.” He added that the MPCA had received reports of several other sick dogs likely exposed to the algae.

Compounding the sadness, the dog that died after exposure in Fox Lake, a black Lab named Sady, was a wedding gift to the dog’s owners from a friend and soldier killed in Iraq.

Arizona Public Service, the state’s largest electricity provider, has secured $70.5 million in stimulus funds to expand an innovative project that turns carbon dioxide emissions from a coal power plant into biofuel using algae. While part of the funds will be used to scale up the algae processing portion, some of the funds will also be used to investigate the potential benefits of turning the coal into a gas prior to burning it for power.

The concept of creating two products — electricity and fuel — from the same process is known as cogeneration. In this case, the cogeneration also helps to reduce environmental pollution. It’s an idea that has been gathering support as a way to make coal less polluting while finding an additional revenue source to pay for the pollution control itself. In fact, a while back I reported on a similar pilot project in Oregon.

Imagine driving from San Francisco to New York City in a plug-in hybrid Prius that uses algae for fuel.

At the beginning of this month the first ever algae-powered plug-in set off on a ten day coast to coast demo from California to show that a plug-in hybrid can be fueled with green crude.

The algae fuel for the plug-in Prius was supplied by Sapphire Energy. They are developing an algae fuel completely compatible with current gas pumps and pipeline infrastructure.

In an effort to drum up attention and support for their algae-based biofuel, Sapphire Energy has announced they will conduct a coast-to-coast journey in their “Algaeus” plug-in hybrid. Part electric hybrid, part biofuel vehicle, Sapphire claimes the Algaeus will get 150 miles per gallon from its hybrid/biofuel drivetrain.

The Algaeus will visit 10 cities, starting in San Francisco on September 8th and ending in New York City on the 18th.
