Elon Musk has described Tesla's humanoid robot as the most important product it is developing in 2022, with the potential to be "more significant" than the company's car business. The as-yet unreleased Optimus robot is being built to serve as a general purpose robot, though early versions will have more limited factory-based applications. Mr Musk said during an earnings call on Wednesday that a working prototype of the Tesla bot will be unveiled at some point this year. The world's most valuable auto manufacturer is designing Optimus in a humanoid form in order for it to carry out everyday human tasks, such as shopping in a supermarket. "Essentially in the future, physical work will be a choice. If you want to do it you can, but you won't need to do it," Mr Musk said during the Tesla AI Day last August.

Steve Langlais, Sea Ray president, said: 'CES presents a unique opportunity to debut the new SLX-R 400e in front of an audience that will truly appreciate its beauty, capabilities and incredible suite of new technologies.' 'This pioneering new model, which will be available in 2020, showcases the kind of unique, advanced technologies that are worthy of the world's largest consumer electronics show.'

A US government agency claims it has battery technology that could outdo anything dreamt up by the likes of Bill Gates and Elon Musk. Advanced Research Projects Agency-Energy (ARPA-E) – a branch of the Department of Energy – says it has several next-generation battery storage projects in the works. While the organisation won't go into details about its technology, it says it has found the'holy grail of batteries' could transform the US electrical grid within five to 10 years. Ellen Williams (right), director of Arpa-E, said her agency has helped kickstart a dozen high-risk projects based on newer technologies that could soon outperform Elon Musk's (left) Tesla batteries The battery division of Musk's Tesla Motors turned a profit in the fourth quarter. This came after the first shipments of its rechargeable products helped to reduce losses from the company's auto business.
