At $40 for the device, if these all get used just once more, it paid for itself. And I assume I can get more than one re-use out of each one. Admittedly, each additional use cycle will be shorter, but if offered a 90Â¢ return on each dollar, then 75Â¢, then 60Â¢, then 50Â¢ etc. who wouldn’t take it?
This might be something that green-leaning city councils should consider underwriting for their citizens, as it will keep hazardous waste down while possibly increasing the awareness of improved electricity storage.
As for the risks of using this, I haven’t seen any issues so far. There is a chance that a battery could burst but other than a mess to clean up, I don’t see a huge issue there. And it’s not 100%: I have a dozen or so batteries that wouldn’t charge (the device signals if it has an unrecoverable battery loaded). But to cut down the amount of hazardous waste by 80% or so is still a clear win.
The Google has a bunch of stuff on this topic.
