The other day I watched a movie entitled "the age of stupid". Long story short, it shows the point of view of someone who, around 2055, survived a human species near eradication and built a tower with all the digital records of mankind and a bunch of other stuff too, like frozen animals, art pieces, etc. Just imagine a Noah's arc on steroids - except for the fact that it's not an arc, it's a tower.
Anyways, he basically spends the entire movie preaching about our inability to be smart about the environment and supporting his words with snippets of TV news (actual footage from our times) about the environment, what oil companies are doing in developing countries, what we do with our cars and our planes, and so forth. This made me realize that I'm probably not doing enough for the environment and should start doing something about that fact.
In any case, today I just read about a new breakthrough in solar energy harnessing. Scientists made a discovery that allows a new type of solar panel to be 6x more efficient than traditional zync panels (the ones typically used today in solar power installations). It can even work underground! Can we ditch oil once we figure out how to replace plastics, now? :)
