Syr Darya River Aral Sea
This is the Syr Darya river where it flows into the North Aral sea. This structure appears to be used to stop the flow of water or reduce it as needed. The water is replenishing the once shrinking North Aral by means of a 30km world bank funded dam.

Solar Impulse Prototype First Flight
Solar Impulse video showing the short first flight of its prototype solar-powered aircraft, HB-SIA, on Dec. 3. Weighing 1,600kg, and with a wing span of 63.4m, the aircraft flew 350m down the runway at Duebendorf, Switzerland, reaching an altitude of just 1m. The first flight was made on battery power. The aircraft’s 11,600-plus solar cells will be connected for full flight tests, to begin early in 2010 at Payerne, Switzerland. The solar cells will recharge the batteries in flight, allowing the aircraft to fly through the night. A 36-hour test flight is planned for mid-2010. The tests will validate the design of a follow-on aircraft, HB-SIB, with which the Solar Impulse team plans to attempt a round-the-world flight in 2012.

Solar Electric PV Car Automobile – Sun Sprint 2000
Solar energy can power vehicles. Anyone can build their own model solar powered car with an inexpensive PV panel and a small electric motor. Larger versions that carry an adult as seen in the “Solar Challenge” and “Race the Sun” contests.
Building model solar cars can be done by children students from ages 10 to adult. Subjects can be global warming, climate change, peak oil, energy supply, photovoltaics, and the future.

Solar Powered Energy Efficient Rammed Earth Home
The historic town of Mesilla, New Mexico is located next to the city of Las Cruces, New Mexico in Southern New Mexico. A perfect setting to create history. Soledad Canyon Earth Builders mission is to build homes that will be historic homes. Homes that will last through many generations. Bill Perry and Sally Williams home located in Mesilla will be one of these homes. The home was completed in 2006. It is situated on five acres with the all coveted view of the Organ Mountain from most rooms in the home. Construction began in 2005. It is a 3,445 square foot home with an 852 sq. ft. garage and 604 sq. ft. of portals. The homes electrical usage is powered by the sun. Sixteen Photovoltaic solar panels are mounted on the roof of the home gathering the sun to generate electricity. Enjoy the tour—look for those 18 rammed earth walls.

What are some positives and negatives about solar power/energy?
not homework just wanting to know.
The positives are: free after initial cost so there will be a payback. It’s slow but better efficiency is coming a long. Payback for an average Solar thermal system (heats water) is relatively quick. About 6-10 years. Consider the system will last 20+ that’s a pretty good return on investment. No pollution involved.
Cons: People who are going solar are not looking at cost in dollars. They are looking at the cost of doing what we’re doing to the environment.
They want to leave a smaller footprint. What is the cost in the long haul if we continue to pollute the earth? Will we have enough money to turn it around in 10, 20, or 30 years?
A good start is a solar hot water system. With the current tax credits it just makes sense. Everyone talks about solar electricity being too expensive and that is true but not solar thermal. It’s the biggest bang for your buck!
Where can I learn all about green living like rural off the grid ect?
I saw a show of some people living off the land with solar energy, bio diesel, farms, earth made walls, vegetable oil and hydrogen cars, ect.
I would like to see a site or a book or a community that would teach me so I can have thorough knowledge and learn all the ins and outs and learn what works and what doesnt ect and break from a lot of spoiled ways and other things that I am not even aware of.
