This is very interesting and proof that there are plenty of technological solutions.
So, how much of YOUR money have you invested in this so called technology? I will have more respect if you are a doer and not just a talker.
I have invested in clean tech and renewable energy.
Not sure how to go about investing in something like this.
I don't have the kind of resources to be that terribly intersting for sophisticated investors, but I certainly would put 5% of my portfolio into this type of investment.
