Green Water

If you're up on your environmental news, you already know water is a big issue. We're not only running out of clean tap water, we're spending billions of dollars and polluting the environment as we haul bottled water all over the country (much of which comes from municipal water supplies). Drought is such an issue here in California, desalinization plants are starting to pop up in the Pacific, but they're controversial too because of the negative effects on our fragile aquatic ecosystems. It's only a matter of years before water is more prized than oil.

So what's the answer? How to avoid water wars in the near future and how to quench our thirst for clean drinking water in an increasingly toxic environment? One answer might be the new technology behind DewPointe Atmospheric Water Generator. Made by Atmospheric Water Systems, the DewPoint device, which looks like a sleek, futuristic water cooler, extracts water from the air, filters it, and keeps about six gallons, hot and/or cold, in storage as long as the unit is plugged in. Maybe best of all, the water is 99.99% free of all chemicals and contaminants and the device only costs about $0.60 per day to keep plugged in, much like your fridge.
So how does it work? Well, without getting too technical, the DewPointe makes indoor rain, condensing and collecting the moisture much like a dehumidifier might. But unlike a dehumidifier, the water collected is filtered many different ways (including pre- and post-carbon filtered and ultra-violet-ly). According to Atmospheric Water Systems, there are 3.1 quadrillion gallons of water in the atmosphere for the taking at any given time—a big number that might produce big-time relief in the future. Anyone already have the DewPoint or another, similar device? Let us know what you think.

The Most (and Least) Expensive States for Staying Warm This Winter

It’s that time of year again: Temperatures outside have plummeted, while your monthly heating bill is on the rise. If you want an idea of how much heat will cost you this winter (perhaps you blocked out last year’s damage to your bank account), one reliable indicator is location.

Average energy expenses vary from state to state due to factors like weather, house size, and local gas prices. Using data from sources including the U.S. Energy Information Administration and the Environmental Protection Agency, WalletHub calculated the average monthly utility bill totals for all 50 states plus Washington D.C. in 2017.

The personal finance website looked at four energy costs: electricity, natural gas, car fuel, and home heating oil. After putting these components together, Connecticut was found to be the state with the highest energy costs in 2017, with an average of $380 in monthly bills, followed by Alaska with $332 and Rhode Island with $329.

That includes data from the summer and winter months. For a better picture of which state’s residents spend the most on heat, we have to look at the individual energy costs. Michigan, which ranks 33rd overall, outdoes every other state in the natural gas department with an average bill of $60 a month. Alaska is close behind with $59, followed by Rhode Island With $58.

People living in Maine prefer oil to heat their homes, spending $84 a month on the fuel source. All six New England states—Maine, Connecticut, Rhode Island, Vermont, New Hampshire, and Massachusetts—occupy the top six spots in this category.

So which state should you move to if you want to see your heating bill disappear? In Florida, the average household spends just $3 a month on natural gas and $0 on heating oil. In Hawaii, on average, the oil bill is $0 as well, and slightly higher for gas at $4. Of course, they make up for it when it comes time to crank up the AC: Both states break the top 10 in highest electricity costs.

Why Are Glaciers Blue?

The bright azure blue sported by many glaciers is one of nature's most stunning hues. But how does it happen, when the snow we see is usually white? As Joe Hanson of It's Okay to Be Smart explains in the video below, the snow and ice we see mostly looks white, cloudy, or clear because all of the visible light striking its surface is reflected back to us. But glaciers have a totally different structure—their many layers of tightly compressed snow means light has to travel much further, and is scattered many times throughout the depths. As the light bounces around, the light at the red and yellow end of the spectrum gets absorbed thanks to the vibrations of the water molecules inside the ice, leaving only blue and green light behind. For the details of exactly why that happens, check out Hanson's trip to Alaska's beautiful (and endangered) Mendenhall Glacier below.
