Riversimple
The Riversimple car can reach 80km/hr (50mph) with a range of 322km (200 miles), with fuel consumption claimed to be equivalent to 300 mpg. The cars will be leased with fuel and repair costs included, at an estimated $315 (£200) per month. The company hopes to have the vehicles in production by 2013; next year, it will release 10 prototypes in an unconfirmed UK city Photograph: PR
Nominated by Wayne Hemingway and Sebastian Conran
"I use it two or three times a week." says Hemingway. "It's affordable, simple to use; the bikes are solid; the strap and basket holds my briefcase safely; the docking system has ensured that there is minimal theft; it's well-managed and, most importantly, it's helping to add critical mass of cyclists to a city that needs to teach car drivers (and especially taxi drivers) to be more tolerant of the cycling massive ... a triumph and welcome addition to this great city" Photograph: PR

The rest is stored in a battery for up to three days and can be used for any low-power application. Could prove revolutionary in public spaces, the judges suggest Photograph: Jennie Hills/PR
