Did you know that bubbles can clean water? Specifically, dissolved air flotation (DAF) and ultrasound are two methods of making water safer with bubbles. DAF can be used to replace sedimentation in municipal drinking water treatment. Large particles are typically settled out using gravity, but with DAF, bubbles are produced by an oxygen tank pumping air into the bottom of a basin and small particles attach to the sides of the bubbles. The bubbles rise to the top of the basin and the particles are swept off the surface of the water by a skimmer.
On Sunday night we arrived back at the University from our trip to Hubbard Brook Experimental Forest in New Hampshire. There were around a hundred researchers who attended the annual conference there. And let me tell you, not a single one wasn’t in shape. The mountain was steep, with an occasional dirt path leading the way, but other times you had to bushwhack to get where you were going. Although I had no cell service or internet for miles around and people were scarce, the restaurants we ate at were pure heaven. In the picture above: Woodstock Station and Brewery, view from Shamrock Motel of the White Mountains, the lab, and view of the brook. Continue reading “Hubbard Brook”
Echoing Green is a non-profit organization that provides support to entrepreneurs with solutions to social issues worldwide. Once an entrepreneur presents their idea, they are granted 90 thousand dollars to start their business. Financial advisers and other professionals support each business as they take off with their innovations. I chose to cover three such innovations and their creators on the blog today because I find non-profits essential to humanity. Sometimes it gets discouraging to think about how much financial support is needed to start a business. With Echoing Green, those issues are taken care of and inventors are allowed to do what they do best. They are free to create.
I ended this semester right by traveling to the boonies where my friend owns a quaint little cabin. It was hot in Cuba, NY but not nearly as hot as the real Cuba. I have to share my experience because the cabin was such an efficient use of space! There were 16 people having a blast in that cabin and there was still room for more. The bathroom had a great shower, toilet, sink, soap, and there was a microwave, stove, oven, and fridge in the kitchen. There were bunk beds everywhere, a master bed, even more places to sleep upstairs, couches, a television with a gaming system, the list goes on…It was very organized. My friend said his grandpa bought the cabin years ago and fixed it up himself. They even added their own balcony to the second floor. The cabin was practically livable. A lot of thought and upkeep went into it, but the result was amazing.
When trends die, where do they go? You may be surprised to find that junk can go in more places than just the trash. In fact, there are five possibilities:
- Combustion – incineration is a popular method used in regions such as Japan but not the U.S.
- Recycle – recycling companies melt down certain materials so they can become new products
- Reuse – for example, rinsing out your starbucks cup and using it again instead of throwing it out
- Re-purpose – for instance, turning a broken sled into a new shelf

I was standing in front of the window of our small apartment. I could barely see it at my height. Perhaps it is one of my first memories. The sky was a purple and pink hue. It looked so pretty but Mom said there was a storm. You shouldn’t stand near a window in a storm. Continue reading “Storms”
