Presidential Debates avoid climate change

It’s sad, but for the first time in 24 years, climate change wasn’t mentioned in the presidential debates.  This is an issue of growing concern to our national security and well-being, yet it’s become so incredibly polarized and political in this country that we can’t even talk about it.  That’s just plain wrong.  We need to set aside the politics and look at the facts, for this is an issue that will be harder to deal with the longer we wait.

UPDATE: The New York Times has a great article on this subject here, too.

Growing strain on our water supply

With an increasing population tapping depleting aquifers, much of this country (and the world) is on an unsustainable path that is going to lead to water shortages at some point in our lifetimes.  We will adapt, it’s what we’re good at, but we need to be aware of how water is being used in our lives to know what to change.  I’ve seen a few topics in the news lately that might not be obvious water hogs.

The first is fracking, for which the debate seems to focus on threats to our water supply, caused by leaking fracking fluids which threatens our groundwater supplies.  While that’s being debated endlessly, there’s another water issue being overlooked.  That is, the water that is used by the fracking process.  According to Frack Free Colorado, each well requires 2-8 million gallons of water to create, and may require additional water over its lifetime if it needs to be re-fracked.

Biofuel is talked about as one solution to our energy problems, providing both a local fuel source, and a lower carbon liquid fuel option.  Well, notice that word, ‘liquid’?  You guessed it, biofuel production uses large amounts of water.  The world consumes about 32 billion barrels of oil per year…that’s about 1.34 trillion gallons.  One gallon of biofuel takes about 3.25 gallons of water to produce…the math just doesn’t add up here.  When water shortages occur, the priority will have to be water for people and crops…there just won’t be enough water left to use for fracking or biofuel production.

Lastly, there’s the issue of groundwater pollution…which isn’t something most people really think about.  However, check out the EPA’s How’s My Waterway website to get the scoop on water quality of streams and rivers near you.  It’ll tell you about water tests for metals, pathogens, pesticides, etc.  You might be surprised by what you find…I know I was!

Crowdsourcing medical research

Researchers in Sweden have developed a genetically engineered virus that they believe may be able to fight some forms of cancer.  While that sounds great, they ran into a reality check when they looked at doing clinical trials…what they need to do to truly test this virus is going to cost one heck of a lot of money, and finding backers for that is not easy.  So, they’ve turned to the internet for help, hoping to raise around three million dollars to allow them to tackle the first phase of the clinical trials.  If that test is successful, the hope is that it would spur enough interest from big companies to foot the bill for continuation and completion of testing.  You can read more about it here, or check out the video below.

Making fuel from air

A company in England, Air Fuel Synthesis, has demonstrated a method of making a liquid hydrocarbon fuel from nothing more than air.  Well, more specifically, they say the process:

“captures carbon dioxide and water from the air, electrolyzes the water to make hydrogen, and reacts the carbon dioxide and hydrogen together to make hydrocarbon fuels”

Naturally, they believe it is a scalable process but is so far confined to laboratory volumes – they’ve produced five liters since August, which is fantastic but they have a ways to go.  What’s key here, too, is how much energy is consumed in this process, something that so far I can’t find details of.  If powered by solar or wind, though, a process like this could theoretically be nearly carbon neutral, yet still provide fuel to power cars and trucks.  Or, if coupled with a utility-scale solar panel installation, some excess solar energy could be funneled to this process during the day, producing fuel which can power generators during the night when the panels aren’t producing.

A quick video primer on Dark Energy

If you’re curious about dark energy, check out this short video giving a high-level overview of what dark energy is (well, at least what we know about it, that is…we don’t really KNOW what it is), and how scientists are working to learn more about it.  There’s also a great FAQ on the subject at Discover Magazine’s website…it’s really long, but then, dark energy is a complicated subject!
