SpaceX Update

The FCC has granted Elon Musk's SpaceX a license for up to a million terminals that will allow Starlink satellites to deliver broadband service. The decision was shown in a public notice from the FCC on March 18. “Granting this application would serve the public interest by helping to speed broadband deployment throughout the United States by authorizing the ground-based component of SpaceX’s satellite system,” says the FCC.

GeekWire reports that Starlink satellites are being made at the SpaceX facilities in Washington, at a rate of 6 per day. 360 satellites have been launched, with thousands more to come. The service is slated to begin in 2020.

More Satellites

Last month I wrote about a handful of companies adding satellites for new internet and TV broadband services. LINK
Elon Musk is at it again. SpaceX has just filed for permission to add 30,000 more satellites to the 12,000 already approved. The company has deployed a few of the first 12,000 already and plans to have more deployed by the end of 2019.

There are strict international rules for deployment size, weight, height of orbit, wave length for transmitting signals, etc. Nonetheless, many "experts" (fearmongers) have complained that space is cluttered with too many satellites already and worry about accidents as they might bump into each other.
To add perspective, as of January 2019, about 8,950 satellites were placed into Earth orbit since 1957. About 5,000 of those were still in space, according to the European Space Agency. Only about 1,950 of those are still functioning.

As of 2019 here are 276 million cars and trucks on the roads in the United States alone. There are over 1.4 billion cars, trucks, and buses around the world. Neither figure includes off road vehicles. Since space is infinitely larger than earth, it seems unlikely mankind will be able to fill it up any time soon.

Artificial Intelligence

Making sure Artificial Intelligence (AI) does what we want and behaves in predictable ways will be crucial as the technology becomes increasingly ubiquitous. It is an area frequently neglected in the race to develop products, but DeepMind has now outlined its research agenda to tackle the problem.
AI safety, as the field is known, has been gaining prominence in recent years. That is probably at least partly down to the overzealous warnings of a coming AI apocalypse from Elon Musk and Stephen Hawking. It is also recognition of the fact that AI technology is quickly pervading all aspects of our lives, making decisions on everything from what movies we watch to whether we get a mortgage.
That is why DeepMind hired researchers who specialize in foreseeing the unforeseen consequences of the way we built AI back in 2016. The team has spelled out the three key domains they think require research if we are going to build autonomous machines that do what we want.

In a new blog designed to provide updates on the team’s work, they introduce the ideas of specification, robustness, and assurance, which they say will act as the cornerstones of future research. Specification involves making sure AI systems do what their operator intends; robustness means a system can cope with changes to its environment and attempts to throw it off course; and assurance involves our ability to understand what systems are doing and how to control them.

Where is Starman Now

Elon Musk made history again with his sending a Tesla and Starman into space. Here is a website that is tracking the car in real time along its journey. Fun short term diversion. 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.
