Whose Lives Will Change Most as Fossil Fuel Prices Rise?

Fossil fuel prices will rise. There’s no doubting that, in the absence of any other supply of cheap, high volume energy, fossil fuel supplies will decline, and prices will rise as population continues to explode.  It is interesting to examine who is most likely to feel the effects of the change, as I don’t think many people, at least in North America where I live, are thinking about it.  In the end, it appears that the middle classes in the most developed countries and in the temperate climates will feel the effects the most.

Will Anything Reduce Global Birth Rates and Carbon Emissions Except Fossil Fuel Shortages?

Today the news proclaimed that agreements were made at the G-8 summit in Italy to hold global warming to a maximum of 2 degrees Centrigrade.  It was a very positive step to see that the United States has finally joined most of the rest the world in making a commitment to fighting climate change.  Will people really be able to do this, though?  And aren’t population and energy use just as important if not moreso?

Can a Video Screen Be Painted on Using Nanotechnology?

Combining the ideas of wi-fi, nanotechnology, microtechnology, and optics could produce a video screen that can be painted on a surface in layers that will then self-assemble into operating, light-producing video screens.  Perhaps each pixel could be a tiny nanobot incorporating one or more colors of LED that it can turn on and off.  Energy can be derived from a gel or circulating liquid bath (with the added advantage of cooling the nanobots).  The controls to make each nanobot turn its light sources on and off can be implemented through data-encoded near infrared light so as to be invisible.  Such a light might provide an energy source to the pixelbots as well.  Could a modulated light source transmit enough data to address each nanobot individually  and pass control information quickly enough for the whole screen assembly to produce real-time video?
