One of the most economically lucrative idea: Currency exchange predictor. What if you knew when the dollar price will go up and by how much, when will it fall. You can earn and pretty much make a living out of this knowledge. And you know what is behind all of this BI !!!
Using the basic knowledge of currency exchange, some awareness of world affairs and guts to invest money is all you need. I had done a very detailed report back in India but sadly it seems I have lost it. Here I have collected the 10 years of U.S. $ data from::
http://www.bankofcanada.ca/rates/exchange/10-year-lookup/
and made something very trivial but on similar lines.
As we see a periodicity in the trend of how US dollar changed over time. Anyone can capitalize on this information and earn bountiful profits.
Industrial Use: I will take my own example here. My company was based in India and our client was GUESS, US. My company used to get money in dollars and it had to pay us in Indian Rupees. This knowledge of when to get the maximum return from our $ earnings made my Vice President put this project infront of us.
