What invention you what to see "ya" in order to protect the environment.?

Question

Me will like to see a machine where you drop a coin or two or three (inflation??) and with your own cup service your favorite drink. This will save a lot of plastic. Did you imagine, you will have cups for coffee, for water, green tea, coke, etc...

Answer 1

I would like a small fusion engine that runs on hydrogen.

Answer 2

It's not so much an invention as it is a change in a current trend.  I think that all states should charge deposit for all beverages, including bottled water.  This might reduce some of the landfill waste that is being eaten up by mounds and mounds of plastic from water bottles that people are too careless to recycle because they don't see an immediate "reward".

As much as I despise returning empty can and bottles, I would gladly do it in order to help preserve this earth for generations to come.
