Working in tandem with PhD student Robert Rudolf, Reuben developed the first instance of technology that will allow energy consumed by mains connected equipment to be measured without the need for a monitor between the equipment and the wall socket.
The technology uses state of the art sensors with elegant calibration and measurement algorithms.
This resulted in an innovative new device that is a non-invasive multi-core current clamp which can be fitted around a cable and removed with ease. This approach removes the need to access sockets and to power down equipment for the fitting process.
Reuben's spinout company, Joulo, was acquired in 2015 Quby, Europe’s leading develop of smart thermostats and energy displays.
Following the sale of Joulo, Reuben co-founded Future Worlds, an on-campus startup incubator helping aspiring entrepreneurs to change the world with their ideas at the University of Southampton.
“Being involved with the Hub has been extremely useful with its opportunities to network with experienced business owners and entrepreneurs, many of whom have experienced the difficult decisions we are facing numerous times before. There is no question that these opportunities are vital to developing business ideas and raising the profile of our technology.”
