The Wright brothers had 5 major innovations that set them apart: 1. A propellor design that was 90% efficient rather than 50% 2. Wing warping for roll control 3. Rudder attached to the wing warping for controlled turns, solving the adverse yaw problem 4. Innovative balance in the wind tunnel, used the wind tunnel to design the airfoil, as all existing data proved to be wrong by a factor of 2 5. Lightweight gasoline engine The Wrights also engaged in an organized, step-by-step method of development, and carefully documented each step. Modern aircraft design can be traced directly back to the Flyer, and no other claimants. This is all in stark contrast to other claimants to first flight.

Mars Images Reveal Evidence of Ancient Lakes 128

Matt_dk writes "Spectacular satellite images suggest that Mars was warm enough to sustain lakes three billion years ago, a period that was previously thought to be too cold and arid to sustain water on the surface, according to research published today in the journal Geology. Earlier research had suggested that Mars had a warm and wet early history but that between 4 billion and 3.8 billion years ago, before the Hesperian Epoch, the planet lost most of its atmosphere and became cold and dry. In the new study, the researchers analysed detailed images from NASA’s Mars Reconnaissance Orbiter, which is currently circling the red planet, and concluded that there were later episodes where Mars experienced warm and wet periods."

Antarctic's First Plane, Found In Ice 110

Arvisp writes "In 1912 Australian explorer Douglas Mawson planned to fly over the southern pole. His lost plane has now been found. The plane – the first off the Vickers production line in Britain – was built in 1911, only eight years after the Wright brothers executed the first powered flight. For the past three years, a team of Australian explorers has been engaged in a fruitless search for the aircraft, last seen in 1975. Then on Friday, a carpenter with the team, Mark Farrell, struck gold: wandering along the icy shore near the team's camp, he noticed large fragments of metal sitting among the rocks, just a few inches beneath the water."

Every year, people accidentally kill themselves with home generators. If you're going to use one, do not bring it indoors. Do not run it in the garage, even with the garage door open. I had mine outside and was still getting CO inside from it - turns out the generator must be a minimum of 10 feet away from the house, with the exhaust port pointed away. The next thing is, don't plug the generator wiring into your home electrical wiring. This will put juice back into the electric company's wires, and can electrocute the poor guy trying to repair the wires to your house. So, to use a generator, use extension cords with it. Make sure they are heavy duty ones, a lamp cord will fry. Let me emphasize heavy duty. At least 12 guage. Pay attention to how much amperage you're trying to draw through the cord and make sure it is heavy enough. You can hook it up to your home wiring system using a device called a "gentrans", which will isolate the generator from the power grid. You'll need a decent electrician to install one, but if your power goes out a lot, it's worth it.
