Using graphene to filter and desalinate saltwater

As the global population increases and water supplies become less predictable due to global warming, finding sources of clean drinking water becomes even more critical. Just ask residents of Cape Town, which expects to run out of water around April 12nd! The obvious solution is to desalinate ocean water, but that’s a very energy-intensive process. Well, researchers in Australia found a way to use a graphene film to act as a filter; its structure allows water molecules to pass through but blocks larger contaminant particles. Most membrane filters get clogged up quickly, but this one keeps working even as it gets coated in contaminants. It’s nowhere near a commercial product yet, but is a promising solution to a growing global concern.

The end of the road for the internal combustion automobile engine

The days of gas-powered cars are numbered. Sure, electric cars are cool and promising and are gaining in popularity worldwide, but an announcement by Volvo really helps make clear the powertrain of the future.  As reported by MotorAuthority, Volvo is no longer working on any next generation gasoline powered engines.  This doesn’t mean they’ll stop SELLING them any time soon…the current generation can last quite some time, I’m sure.  But they’re looking ahead, and they apparently don’t see the profit in developing new gas engines, not with the rise of electrics.  A big step, really, and one I expect other car companies will emulate.  Or…maybe it’s just a publicity stunt?  Volvo is owned by Chinese company Geely…so are they making this announcement for the eco-friendly news benefit, while actually planning to switch to Geely engines in the future if electrics haven’t reached the point needed by then?

Also in electric vehicle news…delivery company DHL did the math on Tesla’s new semi truck, and figured they’d break even on it in less than two years, compared to a conventional diesel truck.  For large companies that are willing to invest in capital equipment like this, switching their short/mid range fleets to electric is really a no-brainer!  It’s only a matter of time, too, before trucks like the Tesla are suitable for long-haul trucking.

Extinction nears for right whales

The news is bleak for North Atlantic right whales, a critically endangered species with only around 400 left.  After a year which saw 18 known deaths (most of which are due to getting tangled up in fishing gear), there have been no new calves sighted this year, worsening an already downward trend in births.  That kind of math doesn’t bode well for the future of this species.

The Boston Globe has a longer article on this if you’re interested.

Kids fighting to protect the climate for their future

Climate change is not something that will impact the old farts in Congress, which perhaps explain their inaction on the issue.  It will, however, greatly affect today’s children.  I’ve been watching an effort to use the American judicial system to force change on this issue, and while its original trial date of February 5th was delayed due to Trump tactics, that case is proceeding.  It’s worth reading more about at ourchildrenstrust.org.  From the website:

Their complaint asserts that, through the government’s affirmative actions that cause climate change, it has violated the youngest generation’s constitutional rights to life, liberty, and property, as well as failed to protect essential public trust resources.

The reason for this blog post though, is to raise awareness of a new initiative, this one targeting the government of Washington state.  Their approach is similar, arguing that the state’s actions,

…severely endangers plaintiffs and their ability to grow to adulthood safely and enjoy the rights, benefits, and privileges of past generations of Washingtonians due to the resulting climate change.

It’s hard to argue with this line of reason.  Well unless you’re a climate change denier of course!   Read more here.

The sound of silence

So I’m curious…has anyone heard of studies looking at the effect of spending all day, every day, in a noisy environment?  Not at a harmful level, but, say, music playing in the background all the time?  I’m really liking my new HomePod and realized that it’s basically playing music for me all day long, all the time.  I’m not growing bored with the stations like I did with Pandora (through the Amazon Echo), so I just leave it on.  I DO still get out to enjoy the silence on my long runs…just kinda a new thing for me, to always have music playing in the house…
