Susan Murcott, Bob Lange, and Richard Komp are three grassroots environmental activists who are changing lives all around the world.  Susan is a water researcher whose work on simple water filters has benefitted the lives of hundreds of thousands of people from Guatemala to Ghana.  Her latest project is building a block of toilets for a school in a village in Ghana, the second project of this kind she has been involved with.  Bob is a physics professor who has been doing science education in Africa for many years, an activity that morphed into installing small solar systems for villages in Tanzania and now into designing, building, and installing efficient cookstoves with the Maasai people.  This year, his work is expanding into Uganda.  Richard is a solar expert who has worked on everything from the physics of solar electricity to building solar stoves from scrap.   He has been teaching people all around the world how to do solar as a cottage industry for about three decades now.  His latest idea is to outfit a sailboat as a floating solar workshop that can teach people throughout the Caribbean how to better their lives with simple solar technologies. You can read his reports on his international work at http://www.mainesolar.org/Komp…

I consider myself immensely privileged to know all three of these remarkable and remarkably effective people.

This greenhouse at the former historic Fisherville Mill in South Grafton, Massachusetts, sits on the banks of a canal by the Blackstone River.  It is cleaning stormwater runoff and water contaminated by #6 fuel oil, also known as Bunker C oil, which leaked from underground tanks.  At the end of the process, 95% of the hydrocarbons are removed without the application of chemicals, using only ecological design.

The Blackstone River can rightfully claim to be the birthplace of the Industrial Revolution in the USA as in 1790, Samuel Slater built the first water-powered spinning mill in America for Moses Brown, a founder of Brown University, in Pawtucket, RI using the Blackstone River as a power source.  By October 7, 1828, the Blackstone Canal from Providence, RI to Worcester, MA was completed and became the original industrial corridor of the United States.  Some say the Blackstone was the hardest working river of 19th century America with its water powering factories all along its length.

Perhaps now it will become an example of 21st century American technology that uses ecological systems thinking to clean up the wastes industrial development has left in its wake.  

On June 25, the world’s largest solar ship, the MS Tûranor PlanetSolar (http://www.planetsolar.org), was docked in Boston and hosted a symposium on water and climate change, “From the Alps to the Atlantic.” This 35 meter by 23 meter catamaran is currently on the DeepWater expedition, harvesting data from the Gulf Stream after a maiden voyage around the world on the equator.  From Boston she is bound for St John’s, Newfoundland, Reykjavik, Iceland and finally Bergen, Norway.  After the transatlantic DeepWater expedition, the PlanetSolar will work with the Waste Free Oceans Foundation (http://www.wastefreeoceans.eu) to clean up European waters.  The research team from University of Geneva is headed by Professor Martin Beniston and consists of climatologists, physicists, and biologists.  

The PlanetSolar has 512m2 of PV cells and the largest civilian mobile battery in the world providing 20 kW of electricity, 17kW for two 60kW electric motors,  with 3 kW for life on board, for an average speed of 5 knots and a maximum speed of 14 knots.  The PlanetSolar is a traveling experiment laboratory and sampling station working on water issues around the world with room for a crew of nine.

The symposium included talks on the global water cycle including river systems (http://www.globalrivers.org), glaciers and mountain water resources (http://www.acqwa.ch), ocean ecology, acidification, phytoplankton and zooplankton biology, and other issues.
