2017, Dyson announced a significant expansion programme in the UK, opening a new high-tech campus on the former RAF Hullavington Airfield in Hullavington, Wiltshire, about south of its Malmesbury site. It has been suggested that research there will focus on battery technologies, following the acquisition of US start-up Sakti3, and robotics. Headquarters relocation to Singapore On 22 January 2019, Dyson announced plans to move its company headquarters to Singapore, citing its intention to be closer with its fastest growing markets throughout the Asia-Pacific as well as stating its unhappiness when dealing with the European Union (EU), which it perceives as being overly bureaucratic. Its headquarters are located at the St James Power Station, a former coal-fired power plant which it leased. The building underwent restoration works from 2019 to 2021. It officially began moving to its headquarters in end-2021; the now restored St James Power Station was subsequently officially completed on 4 March 2022. In 2022, Dyson announced that it would be investing a further S$1.5 billion in Singapore. Products Dyson designs, manufactures and sells household appliances such as vacuum cleaners, air purifiers, hand dryers, bladeless fans, heaters, hair dryers, and lights. Research projects Robotic vacuum cleaners In 2014, Dyson invested in a joint robotics lab with Imperial College London to investigate vision systems and engineer a generation of household robots. In 2001 the company had been close to launching a robot vacuum, the DC06, but James Dyson pulled it from the production line as it was too heavy and slow. In 2016, Dyson launched the 360 Eye, and in 2021 the 360 Heurist. Collaboration with universities Dyson funded a professorship at the University of Cambridge Department of Engineering in November 2011, adding to earlier funding of post-doctorate research. The Dyson Professor of Fluid Mechanics focuses on teaching and researching the science and engineering behind air movement. In addition, Dyson invested hundreds of thousands of pounds in a Dyson research branch at Newcastle University in May 2012, to investigate the next generation of Dyson digital motors and motor drives. Solid-state batteries In March 2015, Dyson invested in its first outside business, paying $15m for an undisclosed stake in US battery start-up Sakti3, which is developing solid-state batteries. Dyson acquired the remaining stake in Sakti3 for $90m in October 2015. Dyson researchers had been working on battery technology since 2010. In 2017, Dyson abandoned its licensing of patents held by the
