I watched a segment (on the Science channel) about BigBelly, a solar-powered trash 
compacting garbage bin that’s currently being used in some areas of New York. Built and developed by Seahorse Power Company and priced around $4,500, it crushes garbage based on some algorithm into eighth of its size when needed; thus, reducing the frequency of garbage collection. Well worth it, I think, considering the resources needed in a city like New York.
What’s really a nice feature is it can last up to 4 weeks (on full charge) without sunlight, and still crush garbage efficiently. This is definitely one of those innovations that we humans desperately need, since garbage is a big problem these days. Nice…
Don’t you love living in the 21st century? I do.
