Elon Musk, co-founder and head of product design at Tesla Motors Inc. (NASDAQ:TSLA), will speak tonight at D11, the annual conference from AllThingsD in Rancho Palos Verdes, Calif. He is scheduled to speak at 7:30 p.m.

As co-founder of Tesla Motors, Musk helped produce the world’s first fully electric sports car. The company’s Tesla Model S was named the 2013 Motor Trend Car of the Year, and, after paying off its federal loans nine years early, Tesla's stock is soaring.

The fiery industrialist also speaks his mind freely, often engaging in Twitter feuds with critics, so we can only imagine what the self-described workaholic will discuss at D11. Will Musk discuss his proposed “affordable” Tesla model for under $40,000? He has previously said the car would not likely be ready until 2017.

Musk has told Businessweek he was concerned with large-scale problems -- that humanity has no sustainable energy source and that “we are not a multiplanetary species.” His proposed Hyperloop device is a theoretical ultra-high-speed transportation mode and alternative to the plane, train and automobile that, as Elon Musk describes it, sounds like something out of "Star Trek." Speaking of sci-fi, filmmaker Jon Favreau said that Musk was an inspiration behind his depiction of billionaire genius Tony Stark, and Musk himself had a cameo in the 2010 "Iron Man" sequel.

Musk said that his proposed transportation device, the Hyperloop, would be solar-powered, faster than a plane and that passengers would not need a “specific departure time.” Perhaps he will elaborate on his plans for the device, not having discussed it in depth since last year.

Musk tweeted an article on Monday about how Governor Rick Perry signed a bill legalizing the temporary closure of Texas beaches for rocket launches. The bill is anticipating a commercial launch facility that SpaceX is considering building in Cameron County, Texas. SpaceX is also considering sites in Georgia, Florida and Puerto Rico. Will he make an announcement regarding the space transport and tourism company? Check back or follow IBTimes on Twitter for updates.

Musk got into his most recent spat last week after tweeting last week that Tesla was “the only American car company to have fully repaid the government,” goading Chrysler and getting a response from spokesman Gualberto Ranieri. Ranieri responded in a release that the information in the tweet was “unmistakably correct,” noting that Chrysler had repaid its loans two years ago.

Musk retorted by noting that since Chrysler is controlled by Fiat of Italy, it is not an American car company. He also said Chrysler “failed to pay back $1.3B. Apart from those 2 points, you were totally 1st.” Chrysler has not issued a second response.
