How many cities/states will buy into this?
How much maintenance ($/time) is required for these solar lights on a monthly/yearly basis?
This is on top of purchasing and installing.
How often are roads/highways being resurfaced/repaved?
When I think about living here in Toronto, roads are being resurfaced or repaved almost every year. They city scrapes the roads down and than repaves, it would be extremely time consuming to remove each solar light and than reinstall, which would cause huge delays in getting the roads done.
Great idea, not practical. Lightposts are a one time installation, change a light bulb every couple years, minimal maintenance required and they do the exact same thing. AND far less lightposts are required vs solar lights. You would need hundreds if not thousands to cover one stretch of road. Adding all that up in there really any savings?
