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.

SpaceX catches Falcon Heavy nosecone with net-outfitted boat

It marks another milestone in SpaceX's long-standing effort to make spaceflight cheaper.

Technology & Innovation
  • SpaceX launched Falcon Heavy into space early Tuesday morning.
  • A part of its nosecone – known as a fairing – descended back to Earth using special parachutes.
  • A net-outfitted boat in the Atlantic Ocean successfully caught the reusable fairing, likely saving the company millions of dollars.

Politics & Current Affairs
  • A new report from a United Nation expert warns that an over-reliance on the private sector to mitigate climate change could cause a "climate apartheid."
  • The report criticizes several countries, including the U.S., for taking "short-sighted steps in the wrong direction."
  • The world's poorest populations are most vulnerable to climate change even though they generally contribute the least to global emissions.
