Innovation at everyones feet: Laurence Kemball at TEDxRio+20

[@laurencekemballcook739]

Hi Guys, We have been working really hard to reduce the costs of manufacturing the tiles as we begin to reach scale. When we first started the tiles did indeed cost in excess of $30,000 for 8, the current costs are nearer $5,000 for the same 8 tiles. We will eventually bring the price down to a level similar to standard flooring tiles. In line with the development of the manufacturing we are improving the efficiency of the tiles too, a bit like they did with Solar when it was first developed over 50 years ago. I appreciate your support and watch this space as we continue to push the envelope of the technology further.

What about your concept applied to shoe soles?

[@achalagrawal5598]

Hello sir, your idea is very great but can you give me more information about the materials which are use in manufacturing of it.

Super bajar a la 6 parte, da esperanza y lo que coloque en otro comentario, SI SE MASIFICA esto baja y permite el I+D+i, les escribi un correo...

Outstanding work. What would be the cost per unit to mass produce Pavegen blocks?

[@AdeAderinto]

Any idea of costs?

[@boulosselazarus5012]

ya how much does each tile cost?

I'm sorry, this is just a silly novelty. Yes, a few LEDs can be lit and using "human powered" generation at, for example, gyms where we pay to dump energy into a load is probably not a waste but these tiles are. The energy isn't free, the human does more work walking on these than otherwise and their efficiency is very low. One could argue that it's better if humans put more energy into walking, given obesity trends. But the terribly low power available from a footstep makes these nothing more than a gimmick. Their own site has a "live" display that indicates (viewed today) that about 400 footfalls produced 0.8 watt hours of energy. To put that into perspective, to keep a 10 watt LED bulb (equivalent to a 60 watt incandescent) on for 6 hours would require 30,000 footfalls (60*10*400/0.8). Where I live, these 60 watt hours would cost about $0.008 (8/10 of a penny).

Absolutely useless. What a waste of money.
