Inovative design projects at this year's Royal College of Art Degree show range from a scheme to get power from poo to a chopping board that measures what you eat.
The Innovation Design Engineering course is a joint masters degree run with Imperial College for graduates of disciplines such as engineering. Students have to make working prototypes of their designs and think about sustainability and manufacturing.
Shruti Grover, noting the problem of open toilets in India, has designed a system that allows people to collect their faeces in bags and hand them in for turning into biopower in return for 'points' which can be redeemed against the power produced. She reckons it could meet a quarter of households' energy needs in parts of India and has even designed a hydrogen sulphide detector to scan bags as they are contributed.
Chris Pinches has designed an indoor clothes horse that won't steam up your windows. Humi folds down to store under a bed. Pull it out, pull it up and Humi fans dry the clothes with only 43W of power (compared with the 3kW of a tumble dryer). The moisture is contained in catridges. Pinches is now working on ways to regenerate those cartridges, driving off the moisture at a slower rate than a traditional airer would.
Sebastiaan Wolzak's NUTRI system analyses your food to help you and your family monitor what you eat. As well as the aesthetically pleasing design, he has also built a prototype loaded with electronic sensors to help identify the foods that pass over your chopping board and into your cooking pot.
Other projects include Peter Krige's ingenious water tap design for African slums; Daniel McLaughlin's terracase luggage made from old wool carpet; and Bobby Petersen's paper pulp hemlet and pigeon tower to redomesticate pigeons and harvest phosophorous from their faeces.
The show at RCA Kensington runs until 30 June, 12-8pm daily, at RCA's building next to the Royal Albert Hall on Kensington Gore, London.
