Tesla Model S dyno test

I love cars…especially the sounds they make.  Which is why I found this particularly interesting – it’s a dyno test of the all-electric Tesla Model S!  It’s strange, hearing an electric car do this.

For comparison, here’s one of my favorite dyno test videos of a fossil-fuel car, in this case a turbocharged Lamborghini Murcielago.

Climate change in the news

cracked-earth-textureClimate change is becoming more of a focus for me…we’re learning more and more, but also starting to see more effects of this.  So, I’ll be posting summaries, like this one, of various climate change stories I find on the web, rather than posting them one at a time.

First up, the latest National Climate Assessment, produced by more than 300 government scientists and outside experts, paints a bleak picture for this country.  The report, still in draft form, predicts warming and more extreme weather events.  Read more here.

A forthcoming report from the Intergovernmental Panel on Climate Change was leaked online (not due to be released until September of 2013 as it is not yet peer-reviewed), and paints a grim picture for our civilization…if we continue on our current path, warming will be ‘a catastrophic and unmanageable 10F over much of Earth’s habited and arable land.”  The report also concludes that it is ‘virtually certain’ that human activities are responsible for this global warming.  Read much more about this report here.

The World Bank is raising the red flag about global temperature increases above 4C (7F), saying that “we’re on track for a 4C warmer world marked by extreme heat waves, declining global food stocks, loss of ecosystems and biodiversity, and life-threatening sea level rise.”  Food security is in doubt as temperatures rise, with crop yield reductions and extreme temperatures likely leading to shortages and hunger.  What’s worse is that this 4C ‘danger zone’ is something that our current policies can’t even meet – we’ll overshoot that easily.  Read more here.

The BBC reports that current CO2 emissions are too high to curb climate change, and are increasing, rather than decreasing as we need.

The Washington Post reports that, while there is a wide range of predictions from the various climate models, the National Center for Atmospheric Research is finding that warming is likely to be on the high side of predictions – not good, as it means we’ll substantially overshoot the target world leaders have agreed upon as the limit to avoid catastrophic consequences.

It’s basically all bleak news these days…but what makes it worse is that we have the technology and resources, right now, to make significant reductions in our CO2 emissions but we fail to act.  Future generations will pay the price…and it doesn’t have to be this way.

2012 was the hottest year on record for the US

Not surprisingly, 2012 was the hottest year ever (in recorded history, since 1895) in the continental US.  The 53.3F average temperature was 3.2 degrees above the average for the 20th century, and one degree above the previous high set in 1998.

Also interesting was that, while there were 362 all-time record highs set across the country, there were zero all time record lows recorded.  2012 also ranked as the driest year since 1998, and with 61% of the continental US in moderate to exceptional drought.

Read more in the USA Today or Washington Post.  And let’s hope for a more average 2013…and the political and social willpower to end this crazy terraforming project we’re on before it’s too late.

Lego Mindstorms EV3

GyroBoyLego is releasing its third iteration of the popular Mindstorms robotic construction platform, called Mindstorms EV3.  If you don’t know what Mindstorms is…well it’s more than I can get into in a simple blog post here.  It’s basically a fantastic way to teach kids about robotics.

Read this article at GeekDad for a rundown on what’s new in EV3.  Pretty much what you expect…newer, better, with smartphone integration.  While this latest release is targeted towards educational users, I expect this to appear on many kids’ Christmas lists later this year (and probably on some parents’ lists, too…).

Mindstorms EV3 should be shipping in the second half of this year.

Gravity travels at the speed of light

Researchers in China have managed to measure the speed of gravity, cool!  They found that it travels at roughly the speed of light (.93 to 1.05X, specifically, with a relative error of 5%).  This doesn’t really uproot any scientific doctrine, but anytime we can scientifically prove things like this it helps the whole field advance.  Read more here.
