Why I'm Hot for Solar
Elon Musk is an engineer, entrepreneur and philanthropist of best known for co-founding PayPal, SpaceX and Tesla Motors.
He is currently the CEO and CTO of SpaceX, CEO and Product Architect of Tesla Motors and Chairman of SolarCity. Musk is best known for having created the first viable production electric car of the modern era (Tesla Roadster), for designing a private successor to the Space Shuttle (F9/Dragon) and creating the world's largest Internet payment system (PayPal).
Musk left home in 1988 at the age of 17, without his parents' support, and in part because of the prospect of compulsory service in the South African military during Apartheid.
Musk sold his first company, Zip2, for more than $300 million to AltaVIsta in 1999 and used that money to start the company that would become PayPal. When eBay bought PayPal for $1.5 billion a couple years later, Musk embarked on a couple of big, bold projects: SpaceX (commercial space flight) and Tesla Motors (electric vehicles).
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.
It's a development that could one day lead to much better treatments for osteoporosis, joint damage, and bone fractures.
- Scientists have isolated skeletal stem cells in adult and fetal bones for the first time.
- These cells could one day help treat damaged bone and cartilage.
- The team was able to grow skeletal stem cells from cells found within liposuctioned fat.
Gut bacteria play an important role in how you feel and think and how well your body fights off disease. New research shows that exercise can give your gut bacteria a boost.
- Two studies from the University of Illinois show that gut bacteria can be changed by exercise alone.
- Our understanding of how gut bacteria impacts our overall health is an emerging field, and this research sheds light on the many different ways exercise affects your body.
- Exercising to improve your gut bacteria will prevent diseases and encourage brain health.
A groundbreaking new study shows that octopuses seemed to exhibit uncharacteristically social behavior when given MDMA, the psychedelic drug commonly known as ecstasy.
- 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
