This is a bit far fetched as it does not mention any power density figure. Being compressed likely squeezes out micro watts. Off by at least 6 orders of magnitude.
What's interesting is that these materials can be used as sensors, building small voltages/sending small currents when deformed.

- gs17 2y agoI wondered how the math works out in reality. https://energy-floors.com/products/kinetic-dancefloor/ https://energy-floors.com/products/kinetic-dancefloor/ implies one tile is rated at up to 20 W output. The 44 tiles Coldplay has would then be up to ~800 W (some of them seem less accessible). I guess I don't know enough to figure out how much it saves compared to the emissions of lugging it around, but I'm kind of skeptical it actually "boosts sustainability".

- falcor84 2y agoThey have a solar product too, but their main approach is this: > The weight from each step across Pavegen tiles creates a small vertical movement of 5mm-10mm compressing an electromagnetic generator and creating a rotary motion to produce 2-4 joules of off-grid, clean energy. https://www.pavegen.com/what-can-pavegen-power https://www.pavegen.com/what-can-pavegen-power
- BriggyDwiggs42 2y agoThe solar tiles make me concerned but I suppose I don’t immediately see an issue with the pressure tiles. I hope they turn out useful. Really just down to the life expectancy of the tiles.
- is_true 2y agoI would love to walk over one of those, my guess is you would feel more tired after, similar to walking on sand

- soulofmischief 2y agoFor sure, any energy taken out of the system is coming out of your pockets. How much it taxes each individual is the question, and who profits from that energy extraction. But if we're talking a couple joules I don't really see how this is worth it. Comes across as more environmental individualism propaganda
- lupusreal 2y agoIt is already common for flooring material to yield when stepped on, for ergonomic reasons. Normally that energy all becomes heat. In principle at least, you could capture some of it as electricity without causing pedestrians to exert extra effort. Seems useless though. Every dollar spent on this sort of fancy flooring, which is doubtlessly more expensive than carpet and/or foam rubber mats, is a dollar that isn't being spent on solar panels.
- cjbgkagh 2y agoAFAIK They even had schools designed to limit the students bypassing these generators. Something about having the role of a child being to generate a miniscule amount of electricity seemed very dystopian to me.
- rcxdude 2y agoIt's a scam with investor's current understanding of technology.
