It’s Easy Being Green

Would you believe that it is possible to have a floating greenhouse in New York that actually produces food? Well it is and the full scale greenhouse operation on the Hudson River in New York has once again opened its doors for all to see. The project is called the science barge and is a prototype of a sustainable urban farm. It also serves as an education center. Last year, more than 3,000 school students made their way through the Science Barge.

So what makes the floating greenhouse so special? Inside the greenhouse they grow tomatoes, cucumbers and lettuce with zero emissions and no runoff into the Hudson River. The barge is powered by solar, wind and biofuels and harvests irrigation water by filtering from the Hudson River and catching rainwater. The developers say the Science Barge requires 7 times less land and 4 times less water to grow than conventionally grown crops. In a city like New York, land has skyrocketed to the point that it would be nearly impossible to grow food in town. Riverfront barges could be the answer to the dilemma. Some studies have also suggested that there is enough rooftop space in New York to grown enough food for the entire city.

What are the hopes? The non-profit group New York Sun Works wants to demonstrate that it is possible for cities to reduce their global footprint by looking at ways to provide their own food. They say most land in cities is contaminated and shouldn’t be used to grow food anyway. That’s why they think they’re hydroponic growing system is the best, most sustainable way to grow!

Here’s another interesting toilet upgrade that can help you save water in the long run.  The Sink Positive is a toilet tank lid replacement that could help you use less water and encourage healthy hand washing.  The lid replacement includes a small sink that turns on after you flush the toilet.  As the water runs out of the tap and down the drain, it refills your toilet bowl.  It’s a simple idea that could be effective and essentially refills your toilet using grey water.  Apparently the design has been popular in Japan for some time now but is just now catching on in the U.S.

I personally think the sink would make more sense if you could turn it on whenever you wanted but nonetheless it’s a smart idea.  To find out more about the Sink Positive, visit their website.

There are thousands of sites spread across our globe where groundwater supplies have been contaminated due to dirty factories, military installations and the dumping of toxic waste.  These so-called superfund sites are left to sit until the expensive cleanup operation can get underway and have undoubtedly a harmful impact on our environment and supplies of drinking water.  But one scientist at Rice University has come up with an amazing solution, one that could leave at least part of our planet gleaming!

Chemical engineer Michael Wong developed a gold detergent that is amazing effective at cleaning up water contaminated with toxic waste.  No, this isn’t a hundred dollar bottle of soap that the likes of Paris Hilton would bathe in twice daily!  Typically cleanup of these sites containing the cancer causing chemicals TCE and PCE costs millions of dollars and it never really gets rid of the problem.  TCE is an industrial solvent used to clean greasy machinery and while it smells sweet, the after-affects are anything but.  The current cleanup method is simply a process that moves the chemicals to another spot.  The federal government has suggested that just to clean up the 1,400 military sites would cost $5 Billion.

Wong realized he could combine gold particles (molecule sized) with palladium (another metal) and sprinkle the resulting mixture over contaminated water.  What happened was pure genius!  The gold detergent broke down the TCE and PCE and turned them into a more eco-friendly gas, ethane, and chloride salt.  The gold detergent works about 100 times faster than the current groundwater cleanup method which involves pumping water through charcoal filters to remove the TCE and PCE.  Wong and his partners at Rice will now deploy the system at an actual cleanup site to see just how effective and cost-efficient their gold detergent can be.
