Designer Victor Ong designed his Double-O cooking system to address the issue of limited living space in a world with an ever expanding population. To address cooking needs in smaller apartments or dorms, the Double-O concept utilizes a slide out, tabletop plug-in, two burner solution which ekes out more cooking surface in less space.
Designer Victor Ong explains his solution as such:
In the year 2020, household sizes will be smaller and there will be more singles around. A predicted trend is towards small/medium sized households - consisting of 1 to 3 people. Double-O is a compact and integrated cooking system for urban living, small households and even student dwellings. It is an innovative cooking unit that serves the need to prepare simple and wholesome meals using one appliance. An additional feature of the Double-O is the sliding motion that creates an extra cooking space. It is easy to clean because the sliding base is removable and it is made of wireless contact.
Victor's Double-O concept was amongst the many entries in Design Boom/Electrolux's imagine the home in 2020 competition way back in 2005. We're a little disappointed we have yet to see something like this come to fruition on the consumer end, but note this vacuum concept looks very much like an available model (an Electrolux, branded as TOSHIBA). Unfortunately, most current space saving cooktop solutions aren't so beautifully designed as the concept Double-O, but the Alpes Inox fliptop might hold you over until Electrolux (hopefully) takes the Double-O from concept to consumer product.
