So, for the kitchen in 3015 I proposed the 'Walking machines'. They operate as a public service and his main purpose is to provide you pills with the main nutrients that humans needs, taken by genetic modified molecules. They walk through the city putting on your 'kitchen'(an electronical device) the pills that you and your family needs.
Its main advantage is the reduction of waste and trash (also reducing air and earth pollution), and the efficiency of the time spent on eating and cooking.
I took as an inspiration the idea proposed by British architect Ron Herron in 1964 published in the avant-garde architecture journal Archigram called 'The Walking City'.
