Top 6 Clean Tech Innovations Of 2011 [Slideshow]

Top 6 Clean Tech Innovations Of 2011 [Slideshow]
  • 1 of 6

2011 is almost over, and that means it’s time to reflect on what we’ve accomplished, both personally and as a society, so that we can make our resolutions for a better new year.

Although the fight for a cleaner, more sustainable world suffered repeated setbacks in the political realm (at least in America) there were still plenty of promising developments in the clean technology industry. While politicians continue to stymie government investment in clean energy, transportation, and agricultural advancements that could slow society’s contribution to climate change, entrepreneurs, engineers, and scientists haven’t slowed their work.

The clean tech industry saw more funding in 2011 than ever before, providing hope that while the clean tech revolution is woefully behind schedule, it’s still on its way.

On the following pages you’ll find six of the most promising clean tech innovations of 2011. Think we missed one? Share it in a comment!

1. Clean Rivers Project: Washington, D.C.

DC Clean Rivers Project

Washington D.C.’s Clean Rivers Project will all but eliminate the 2.5 billion gallons of wastewater overflow into the Anacostia and Potomac rivers.  The tunnels come as the area’s largest infrastructure project since the Metro was built and will clean up area rivers as well as the Chesapeake Bay.

These are great ideas, thanks for sharing - I'm assuming some of these are still in production stage...

I love the useage of the fluorescent light bulbs, but they have to be built much better than they are. Seeing that Chinese manufacturers have made the lions share of these products, I suggest that a challange for better longetivity to their poor manufacturing processes bulbs be made by the governments of the consumers. Say, a world wide standard light bulb longetivity be established and that every light bulb manufacturer must prove through continuous life testing that their product will meet these demands. Contrairy to one's beliefs, China can and does produce some quality designed and manufactured products. They just need to be goaded into doing just that.

This comment is directed to Tom W. and Steven M. as I thought they might find it quite informative:

While this motor is still in development, along with related research and development of derivative works, it is exactly what Steven M. was referring to. Steven is correct in that there are variations of this out there that aren't 100% efficient, but are working prototypes, while the Howard Johnson motor isn't complete yet. Progress on the Howard Johnson motor, along with its derivative works and variations, is continuing daily. The goal of the Howard Johnson project is to provide all of the plans, in an Open-Source arrangement, so that anyone could build one and benefit from the project.

Just a little food for thought for today :)

These are some great inventions and changes and I hope we continue on this track and I want some of those window boxes...

I've finally figured it out. Republican support for the NRA and wanting guns in the hands of everybody…
