I saw the theatrical trailer of the movie 2012. Of course I will not watch any disaster grand spectacle movies in the near future, but my mind wandered into another side as I thought about Planet Earth.
See, right now we have petrol. A person can fly to another place say Newyork or Chicago or Finland or Antarctica from Bangalore. Say about 50 years from now, I think the fuel reserves might deplete and petrol might be really costly. Might be in 50 years maybe more.
This also means, an alternate fuel must be examined. We might be heading towards an energy crisis. I did a quick google on Energy crisis and looks like :Hydrogen and Nuclear Fuels may seem to hold the key to our future generations.
Mankind maybe propelled by a Hydrogen based Economy. But from what I read (courtesy Wikipedia) : in practice, production of hydrogen from water requires more energy than the enregy released when the hydrogen is used as fuel. Free hydrogen does not occur naturally, and thus it must be generated by electrolysis of water or some other method. Countries in the world should start thinking of alternatives to Hydrogen production. How to produce Hydrogen cheaply and sell this ? => Very interesting stuff on the net.
Natural Gas might offer a quick solution to this problem, but H2 is a better option because, there is no ash and only water vapour is released which is environment friendly. GD might know better and have a better idea on this ...
And regarding Nuclear Energy it is the case of how well we can control the energy released and how efficiently energy can be utilized. You cannot generate 100000 deg centrigrade in an internal combustion engine. The engine parts may end up being vaporized. Also after hearing abt the side effects of Hiroshima (the hagaisha, hibakusha) and those people, I am really not sure whether Nuke is a great deal. However there is a lot of honcho talk regarding nuclear fuel as an energy investment .... Notice the way John Kerry says "China and India are among the many countries investing heavily in clean-energy technologies that will produce millions of jobs."
Lastly, communications and making the world closer might play a key role in the economies and I expect this sector to grow like anything. So, your super techno handsets can enable you to download a 23.5 Gigabyte leaked BBC Documentary and enable you to see the same in the loo and also act as a room freshner.
So people, invest your monies on these sectors ;-)
