Your ideas to cool the Tube (and win 100k)
1 of 16
Last week Ken Livingstone offered 100,000 for an idea which would cool the Tube. Here are the best of your ideas.
Open top carriages, Richard Miller
2 of 16
Richard Miller of London offers a simple idea - open top carriages.
Aled Powell, ice power
3 of 16
Aled Powell: "Simply re-decorate the stations to make commuters feel like they need their winter woolies in summer."
Andy Glynn, fan
4 of 16
Andy Glynn: "Print maps on flame retardant paper. Passengers concertina their maps and have a handy fold-up fan."
Ed Shore, cooled seats and hand-rails
5 of 16
Ed Shore: "Insert coils of pipe in seats, and then put cold water through them. Use the same technique on hand rails."
Giles Hogben, cold water tank
6 of 16
Giles Hogben: "You have a tank of water for each train. At each station, you pump water out and cold water in."
Harry Sabbers, ice lollies
7 of 16
Harry Sabbers: "This would be both cheap to produce, requiring only water and flavoured syrup, and would be totally delicious."
John Cusick, freezer.
8 of 16
John Cusick: "Ice. Make the train a freezer while it makes human popsicles."
Joseph Yiu, light and water
9 of 16
Joseph Yiu: "Have water curtains. Different coloured lights can be artistic. People will be calmed when trains don't arrive."
Josh Bentley, London Eye.
10 of 16
Josh Bentley: "Crank up the power on the London Eye, and make it an oversized fan."
Julian Burgess, gondolas
11 of 16
Julian Burgess: "Replace tired old tracks and trains with canals and gondolas, the slow pace of travel will make it pleasant."
Mark Coates, wintry posters
12 of 16
Mark Coates: "Put up posters of wintry themes on the walls, snowmen and the like, it's all in the mind you know."
Nigel Wilkinson, heat curtain
13 of 16
Nigel Wilkinson: "A heat curtain would mean trains would stop cooled air going into the tunnels."
Omri Stephenson, peas
14 of 16
Omri Stephenson: "This solution could also be a promotional tie-in with a frozen food company. How can it fail?"
Phil Fanning, Thames
15 of 16
Phil Fanning: "Use the Thames as a cooling medium."
