Google’s solar panels: lucrative and self-cleaning

Written by Auke Hoekstra

google_pvYou might know that Google employed an impressive 1,6 MegaWatt of solar panels on it’s Google campus. You might think that Google only does that to project a green image. Well think again.

Google now estimates that payback time will be 6 to 7 years. That means they got around 12% of interest on their virtually risk-free investment. Not exactly a losers bet!

And after these 6 years the solar cells are not written off. They will go on producing energy for another 20 years of so. How’s that for a smart investment!

Furthermore, Google found that cleaning tilted solar cells is unneccesary. Just let the occasional rain do the work. So the investment is not only risk-free but also hassle-free.

If you live in a sunny location, put those cells up! By now they are cheaper than when Google bought them so your investment could be even more profitable.

It good to be green!

Spirals visualizing progress

Written by Auke Hoekstra
May 18, 2009

To chart our journey ahead, I think it’s useful to realize where we came from, physically and psychologically. When you want to visualize that, spirals are apparently the way to go.

On the physical level I’ve found this beautiful visualization of Evolution, credited to the Enclyclopedia Universalis (HT visual think map):

stevespiral-small

From wikipedia comes this three dimensional spiral:

geological_time_spiral

Both try to make clear how things are speeding up at an incredible rate.

New for me was the fact that people have also used the spiral to visualize our mental evolution. Steve McIntosch does a nice job:

spiral-consiousness

Where “integral consiousness” seems to have many somewhat incoherent believers, there is a rather practical approach behind this called spiral dynamics that I might have to look into in the near future. This summary in particular caught my eye:

Spiral Dynamics describes what Dr. Graves termed biopsychosocial systems along a continuum that forms an expanding spiral. The term, bio-psycho-social, reflects Graves’s insistence on the importance of a multidisciplinary, multidimensional approach to understanding human nature:

  • “Bio” for the neurology and chemical energy of life and the organismic part of us
  • “Psycho” for the variables of personality and life experiences, our temperaments and sense of self and relationships to other
  • “Social” for the collective energy in group dynamics and culture as the interpersonal domain influences human behavior in collective settings ranging from small groups and families to corporations and entire societies
  • “System” for the interdependence and action/reaction of these three upon one another in a coherent whole according to principles laid out in General Systems theory and other approaches to how things work and interact.

Sounds extremely interesting!

Let’s close with another visual, that gives a little bit more specifics on spriral dynamics:

BIG oil: some factoids

Big Oil still rules supreme, that much is clear. I’ve added Sweden for comparison. The total Oil sector is comparable to a large nation like the United Kingdom or Germany.

forbes-top-10

Of all the profits in the top 100, almost 50% was made by the 18 big oil companies.

Six of the worlds ten largest corporations are oil companies. Together their income is bigger than that of Canada, Russia or India.

Royal Dutch Shell is the worlds largest corporation. It’s revenues in 2008 where more than 50% of the total Dutch GNP. So the roughly 100.000 people employed by CEO Jeroen van der Veer earned more than half of what the 16 million people ruled by Prime Minister Jan Peter Balkenende earned. I’ll let you guess who is more powerful…

Maps of the Earth as a superorganism

Written by Auke Hoekstra

I’m fascinated by the idea that the earth can be viewed as a supersystem or a superorganism with humanity as it’s superbrain. Super here does not mean superior. It just means that your primary focus is at a higher level of abstraction. But can you visualise that?

I’ve included some examples for your enjoyment. Please let me know if you find others!

The myth of our peaceful past and violent present

Written by Auke Hoekstra
May 16, 2009

There’s terrorists that have it in for us and each night you can watch countless crime-series.
But how many people realy die a violent death?

dutch-deaths3

As you can see, in Holland it’s unusual to die of a physical cause. Only 30 people out of 900 (3%) die that way. The main causes are falling, suicide and traffic accidents.

But to die because you where attacked by another person is really a rare feat. It happens to only 1 (one!) person out of every  100.000 each year. That’s a 0,001% chance!

So are you afraid to die? Stop worrying about violence! It’s bad for your blood pressure and that’s the biggest personally avoidable cause of death on the planet.
Want to take it a step further? Don’t smoke and lose the extra pounds!

So why are we obsessed with physical deaths?I think it’s a holdover from our hunter-gatherer past. In those day’s, being attacked was a very real possibility:

deaths-due-to-warfare1

As you can see, the relative number of casualties of WW I and II pales in comparison to the violence endemic in current day hunter-gatherer tribes. And in the past it was probably even worse. Keeley calculates that in the past, 87% of tribal societies were at war more than once per year. So far for our idylic picture of the noble savage: our much lamented civilization is definitely doing something right!

Why not treat yourself to this talk by Steven Pinker on the decline of violence?
