Elon Musk is so difficult to keep up with as
he spreads his time between massive projects that each would
consume other mere mortals.
His space roadster and
Starman was one of those projects that we marveled at, but has
since almost slipped from memory. It has traveled more than a
half million miles so far. Here is a site that is still tracking
the vehicle as it continues to fly in orbit around the sun at a
speed of 13,561 mi/h. LINK

Energy and Power
Energy is measured in Joules. Power is measured in Watts. Energy is how far you can run. Power is how fast you can run.
When it comes to batteries, Elon Musk says, "It’s really rare that there’s a big breakthrough because there are so many constraints. You can easily improve, say, the power, but then it’d make the energy worse."
Current electric cars have batteries that provide less power and less energy. This is why the Nissan Leaf has a range of only 84 miles (one-third that of the Tesla Model S) and takes three times as long to get to 60 miles per hour.
Musk's Tesla Gigafactory, being built outside Reno, Nevada, will be the second-largest building in the world by volume. It opens in 2016 and will be complete during 2020. His plan is to build enough batteries to reduce the price and improve the power and energy of batteries, so electric cars can go faster and farther. (The latest edition of the Model S received a score of 103 from Consumer Reports, which was a problem only in that Consumer Reports ratings are typically scored out of 100. The magazine had to revise its scale in response to the record-breaking result.)
In addition, the plant will produce large batteries that store energy in homes and even larger batteries that do the same for utilities and businesses. One of its goals is to make home and business solar power more practical. Current prices are already half what other battery manufacturers charge. Musk says, "The issue with existing batteries is that they suck. They’re expensive. They’re unreliable. They’re stinky. Ugly. Bad in every way." His new battery plane are on the path to fix those problems.
In addition to CEO of Tesla Motors and Space X, Musk is also the chairman of solar energy provider SolarCity.
