Water is actually infinite if it does not leave the earth. We have the technology today to extract fresh water from the ocean. Its just expensive. People will make more money if water is not of abundance. Just goes to show that scarcity makes a lot of money. For example Oil. Instead of the US spending trillions trying to get oil from the middle east, if we spent that much making efficient cars, road systems, trains, we wouldn't need so much oil. Too bad wars make a lot of money.

Tourism is nice and very lucrative (especially with space), but how about you fund something truly for the betterment of the planet. It is no longer an argument that operating a heavily populated "civilised" nation is dependent on electricity (hell one could even make the same case for the internet which is wholly dependent on power).
But in recent years the amount of corporate and government funding for sources of electricity that can surpass the feared generator "break-even" point has waned severly and individual participation by backyard "fusors" (fusion engineers) has skyrocketed: the main difference between the approaches of thee two groups is that the funding goes to the tokamak designs which are inherently flawed at a design level (possibly on purpose) whereas the individual attention has long since shifted to the Polywell design which proved empirically to be much more efficient than anything ever built after the Navy pulled what little funding it had allocated to the project in 2006. its now 2010 and not much has changed electrically since the eighties because the power cost and thresh hold still exist and its all based on a system of planned obsolescence which has gotten bogged down in concepts artificially lengthened because the industries are unwilling to fund a change. What these venture capitalist are trying to do as far as offering a monetary reward for measurable change is great and exciting, though I believe it to be misdirected at whimsical advances.
Bottom line the field of Fusion needs our help more than we need more pictures of the moon, and a simple offer of monetary prizes coupled with the exciting of our inherent competitive nature seems to be necessary to change our world. In closing dream higher, fund Fusion.
