Why I'm Hot for Solar

I feel quite strongly that solar power will be the single largest source of electricity generation by mid-21st century.  In fact, just a simple extrapolation of the growth of solar power tells us it will be for sure.


Consider that the earth is almost entirely solar-powered today and the fact that we’re not a frozen ice ball at, say, 4 degrees kelvin, it’s due to the sun.  And the whole ecosystem is powered by the sun.  

There’s just an itty bitty amount of energy that we need to do complicated human things.  It’s a tiny amount of energy compared to what the sun puts on the earth every day.  And we just need to capture a little bit of that and turn it into electricity.  But we need to accelerate that process as well because we have an unpriced externality in the effects of carbon fuels, and even to some degree, uranium and other fossil materials.  

So we have to try to accelerate that with innovation.  That’s what SolarCity is about.

Giving octopuses ecstasy reveals surprising link to humans

A groundbreaking new study shows that octopuses seemed to exhibit uncharacteristically social behavior when given MDMA, the psychedelic drug commonly known as ecstasy.

Surprising Science
  • Octopuses, like humans, have genes that seem to code for serotonin transporters.
  • Scientists gave MDMA to octopuses to see whether those genes translated into a binding site for serotonin, which regulates emotions and behavior in humans
  • Octopuses, which are typically asocial creatures, seem to get friendlier while on MDMA, suggesting humans have more in common with the strange invertebrates than previously thought
