I dont think it is mentioned that an inmate has to cycle continuously for 16 hrs; I think they might be logging the total number of hours that an inmate cycles, and then for each block of 16 hrs a day is deducted from the sentence.... Same comment for David Ashton above

Interesting idea although transporting the batteries will probably use more energy than was created by the bikes..... Hook it to the grid - small inverters are being used by rooftop solar cells now... Still though the 200w is not much, but perhaps to keep the TV on at home? BTW I think anything an inmate does above and beyond existing is great - especially if the activity helps them to pay back society, or at a minimum support themselves.
This kind of idea could be used in gyms, as mentioned above. Of course the resulting energy would be minimal to the total energy consumption of the gym facility, but every kWh saved is good thing. After all, cutting down the energy consumption is all about making small decisions and innovations that together result in big savings.
yup 16 hours of pedaling is a lot. Should be more like 8 hours or something.
BTW I really doubt, whether this kinda things will really help to solve the power problem. For pedaling 16 hours a day, the prisoners will have to consume "additional energy" as food. And there are 2x conversion losses in this process. ie food to stored fat, Fat to mechanical energy. Instead the food can be directly converted to energy for better conversion efficiency. Anyway, in this case the prisoners are getting some good exercise atleast :)
You could also use this for Gyms - pedal and generate and get reduced fees.....
Ref some of the comments above - anyone who is willing to pedal for 16 hours to get a day off their sentence must have something going for them. 16 hours is a LOT of pedalling.
well, yes, obviously. Although, you'd think that if the crime was severe enough, the jail sentence would be too long for peddling anything particularly meaningful off of it! But if it was, oh, I don't know, Tax Fraud or something... then I think it's an awesome way to repay one's debt to society. Not to mention the fact that keeping people in prison is expensive to local taxpayers, so why shouldn't they be put to work?
Drones are, in essence, flying autonomous vehicles. Pros and cons surrounding drones today might well foreshadow the debate over the development of self-driving cars. In the context of a strongly regulated aviation industry, "self-flying" drones pose a fresh challenge. How safe is it to fly drones in different environments? Should drones be required for visual line of sight – as are piloted airplanes? Join EE Times' Junko Yoshida as she moderates a panel of drone experts.
