Smart-City Technology Harvests Energy From Footsteps
These tiles can harvest energy -- up to 8 watts per footstep -- that can be stored and used to power streetlights or other infrastructure in urban areas where there is significant footfall. (Source: Pavegen)
I agree, Rob, but you're right, you have to have joggers on the tracks to see how the technology is working. I did sort of imagine it would be like the technology you find on those types of tracks, though. Maybe it would be good on some kind of university track, where they have running teams practicing and hosting events.
Hi,, bobjengr, the company was being a bit scant on details about how the technology works for proprietary reasons. I'm not sure offhand about storage but perhaps there is info on the company's website? http://www.pavegen.com/
Hi Rob, the last paragraph in the article suggested that the system generated enough power to run lights for 5 hours when installed outside a subway station in the United Kingdom. We are proposing a Proof of Concept on part of a jogging track in a local health & wellness center for evaluation purposes. A figure of 8 watts per foot step is mentioned.
You're right about softer surfaces being easier on the bones, Elizabeth. One of the suggestions for running training is to train on grass -- because it's easier on the bones and joints while tough on the muscles -- and doing the race on concrete where you get your speed.
One final and very interesting point, Elizabeth; maybe you could post a new report on this [related] topic: After reading how a crowd of thousands could be harnessed to generate electricity, it reminded me of another article where a crowd was harnessed to collectively "think" and solve complex scientific problems, in game-playing format. The boundary conditions of the problems are defined as the "rules" and considering possible solutions is the "game". Click the link to see how Carnegie Mellon's Computer scientist Adrien Treuille created and launched two such problem solving games, Fold-It, and EteRNA. I was absolutely awed and inspired by this story -- maybe you can share it with the Design News readers.
After Googl'ing Pavegen, I saw a few articles on their funding and finances. It appears as if they are always seeking funding, (Seeking Angel Investors, and other Equity Partners) but I didn't see any indication of them planning an IPO. So, I was wondering if you had information on their financial strategy for growth.
Wal-Mart will hold its second Made in the USA Open Call July 7-8, at its headquarters in Bentonville, Ark. The event will be a repeat effort by the world’s biggest seller of consumer goods to increase the amount of US-made products it sells in Wal-Mart stores, in Sam’s Club members-only wholesale outlets, and on walmart.com.
This year, Design News is getting a head start on the Fourth of July celebration. In honor of our country and its legacy of engineering innovation -- in all of its forms -- we are taking you on an alphabetical tour through all 50 states to showcase interesting engineering breakthroughs and historically significant events.
