... http://tinyurl.com/b7433wh ----------------------------------------- If it pans out it will be great! As to people here complaining about solar and the cost. Read the first paragraph in the article. "Solar power is inefficient. Whenever those plains of panels are laid out, the sunlight they convert into stored energy also degrades their effectiveness. With each day the panels spend smoldering under the sun, they become more unreliable in harvesting the rays. For many new systems, designed for lower cost and flexibility, degradation is a huge issue: In just 60 hours, efficiency can sometimes plummet as much as 90%. " And you want to mortgage your kids and grandkids lives to pay for this crap? If they can get efficiency and lifespan at an affordable cost, they go for it. Affordable cost is not having the government subsidize the cost, as that is just shifting who pays the money. |

Of those I would say water. China and India/Bangladesh are already fighting over water from Tibet (maybe a bigger issue than the Dalai Lama) There are also water wars developing in Africa. ----------------------------- We are much more likely to have wars caused by a shortage of water than a shortage of oil. As we are running short of potable, fresh water now. A lot sooner than the end of oil. The earth is still creating oil and gas deep in the ground, but fresh water is becoming more tainted and not being created at the rate we need it. |

Desalination might turn out to be the best application for solar energy. |

Affordable cost is not having the government subsidize the cost, as that is just shifting who pays the money. Almost every invention when first developed was too expensive, unreliable, etc. And an alarming number remain that way until they fade away. Go find a stack of popular mechanics magazines from the 50s and 60s and you will see that far more than half of their "wonderful inventions" are not with us today. As Tim Wilson says "where the **** is my jet pack?" http://forum.grasscity.com/music-gen...im-wilson.html Yeah, the car, the bike, the lawnmower, the electric light, the outboard motor, the refrigerator, the air conditioner, the cotton gin, the steam engine, the rifle, and on and on...... All too expensive and unreliable when first brought out...... |

We were there a few years ago and there were miles of brown fields next to some green ones, simply because of water rationing. === Stop me if I'm wrong but I believe the central valley depends on snow melt for their irrigation water, which in turn is influenced by cyclical ocean temperature patterns in the Pacific. This is the same issue which is causing low water in the Colorado River reservoirs which in the case of Lake Powell and Lake Mead, are down about 60 feet from their maximum levels. Yes but the open question is how fast are they using that water. It is still a finite resource and consumption goes up every year. Actually I think the dams are lower than that unless they are up from when we were there. I am not sure if I have any pictures of the "ring around the tub" but it was striking and more than 60 feet high when we were there. It was certainly a long walk from the marina buildings down to the docks. === The marina buildings are now on floating docks which can be moved in and out (mostly out at this time). The launch ramps are incredibly long, probably close to 1/4 mile. 60 feet is my estimate, might be more. According to this web site lake Powell is almost 81 feet below full pool. http://lakepowell.water-data.com/ All it takes is 3 to 5 years of above average snow fall to bring it all back. One of the issues is that we guarantee Mexico a certain minimum amount of water every year, something like 1.5 million acre feet if my memory is correct. |
