This is Good News Friday, where we find some good economic, energy, and environmental news and share it with PP readers. Please send any positive news to [email protected] with subject header "Good News Friday." We will save and post weekly. Enjoy!


The Power Of A Penny (Tiffany D.)

We’ve only just scratched the surface when it comes to using collectibles to increase and diversify your investments. Collectibles, or what we often refer to as “quiet wealth,” are a way of protecting your assets not only from upheaval in the market, but also from the uncertainty we are facing with a government that has accumulated more than $19 trillion in debt and is militarizing our police force. In fact, collectibles are a wealth solution that we explore with subscribers of The Bauman Letter to add an extra layer of protection in these troubling times.

Humanure: The Next Frontier in Composting (jdargis)

Before you say, “ick!” it’s worth noting that this was common practice until the flush toilet was invented some 400 years ago. In China, “night soil” was collected from each urban household along with the garbage as recently as the 1960s; returning human waste to the land was seen as vital for maintaining soil fertility on the farms that sustained city dwellers.

New images of Saturn’s walnut-shaped moon dazzle scientists (jdargis)

In earlier research, Porco and other planetary scientists have suggested that Pan, as well as Daphnis and some of the other small moons in the Saturn system, were once denser cores that had about one-third to one-half their present size. These cores were perhaps shards left over from other collisions. Over time these cores opened gaps in the rings and subsequently have gathered ring material at their equatorial regions. This material appears to have bunched up at the equator not due to gravity, but rather to forces of the moon's rotation.

The three wonders of the ancient world solving modern water problems (jdargis)

One such baoli restored by the Aga Khan Trust for Culture (AKTC) was built in the 14th century in Hazrat Nizamuddin Basti, a medieval village in Delhi named after Sufi saint, Hazrat Nizamuddin Auliya. In 2008, parts of the baoli walls collapsed due to sewage water seeping into the structure and the local residents using it as a rubbish dump. The pool was drained and the rubbish, garbage and sludge that had accumulated over the past 700 years was removed to reach the foundation of the baoli some 80 feet below ground level. While the water in the baoli is still not potable, it can be used for cleaning and agriculture.

Nothing fishy about new solution for aquaculture wastewater treatment (suziegruber)

The team set up four identical bioreactors, varying only in retention time, or the amount of time it takes for water to travel from end to end. "Retention time varied from 12 to 55 hours in the four bioreactors. If you're trying to treat a lot of water, you want a lower retention time so you can keep it moving through. But the more time you give those bacteria to take the nitrogen out, the more effective they are. We were trying to find a balance between moving water through quickly and making sure it's staying in there long enough to get treated properly," Christianson explains.

Arid land to a fertile Eden: permaculture lessons from Portugal (lambertad)

They started from the top of the hills, hit hardest by erosion and overgrazing. “The wind and the water eroded all the fine earth that should serve as a sponge for the rainwater,” says Mueller. “We started to manipulate the situation so these places retain the rainwater falling on them. Then you start to build structures like swales, which fill with rainwater and slowly filter into the earth.”

Top food companies say there are billions to be made by cutting food waste (jdargis)

Dave Lewis, a group chief executive at Tesco, said that some governments have lagged behind in addressing the food-waste issue because much of the data available to date have been aggregate and relatively simple. In many cases, the information available hasn’t broken down food waste by industry sector. For example, in the UK the dairy industry has very little waste (roughly 1 percent), while the produce industry is in the 20-percent range. This suggests that the two industries would require very different approaches to further reduce food waste.
