Sky Serpent: new and efficient way to produce clean energy
Posted by: | Comments
This is always nice to see a creative idea developped in someone’s garage. Well, this is exactly what Doug Selsam did with his “Sky Serpent”. His impressive design uses twenty-five small turbines instead of the massive blades on a modern wind power plan. To get a better idea, Environmental graffiti explains the technology :
Doug Selsam’s Sky Serpent is the right invention at the right time: traditional turbines are perpetually on back order, and he has 3kw of generation capacity that’s far more affordable and requires fewer materials to build.Selsam, who attended college at UC-Irvine but didn’t graduate, has very little formal training in the ways of physics or wind power, which is probably what left him prepared to break the mold. “This is a 1,000 year-old design” he says of the single-bladed turbine, “I knew if I could get more rotors, I could get more power.”
While on the surface that is in fact true, it flies against the dogma of the engineers and physicists that dominate the wind power community. The complicated physics of ensuring each rotor doesn’t simply encounter the prop wash of the ones in front of it, may have been enough to drive them away. However, Selsam figured out a method: he’s found the proper angle to align his string of rotors at in order to ensure they all have flow, and the optimum spacing for the rotors themselves.
So far, Doug sold 20 dual-rotor turbines that produce 2,000 watts and is getting a lot of attention from engineers. Let’s see where it leads, but it’s clearly a nice technology.

Sky News has an old but interesting and funny article on a company about to commercialize flying saucers:
US company Moller International has begun to manufacture parts for its Jetsons-like personal flying pod, the M200G Volantor.
The M200G is the size of a small car and is designed to take off and land vertically.
Company founder Dr Paul Moller calls the craft “the ultimate off-road vehicle” as it is able to travel over any surface.
“It’s not a hovercraft, although its operation is just as easy,” said the aeronautical engineering boffin.
“You can speed over rocks, swampland, fences, or log-infested waterways with ease because you’re not limited by the surface.”
You can read the article there:

I must admit the whole thing sounds like a scam, but the article wasn’t released on April 1st and Sky News is not a small news network. You can also visit the company’s website: Moller.
The Earth’s axis DIDN’T shift
Posted by: | CommentsSummer Solstice is near and theories are flowing about the axis shift. The sun is too far north, the sun isn’t setting at the proper place, etc. I wrote a previous article about the Earth’s axis shift, just stating that it was completely nonsense to think that the axis of rotation changed but now, I would just like to provide a simple everyday life example of why it doesn’t make sense.
This example is called satellite T.V. I’m sure you know roughly how satellite T.V. works and that the antenna at your home as to be in direct line of sight with the satellite of your satellite T.V. provider. It does make sense, if you want your antenna to receive signal, it has to be in line with the satellite, otherwise it doesn’t receive any signal. Trust me, it’s not something roughly aligned: moving your antenna of a single degree can make a difference. Now, if you want to be able to communicate with the satellite day and night, it has to stay in the same position. How is this achieved? Well, that kind of satellite is called a geosynchronous satellite:
A geosynchronous orbit is simply an orbit that allows the satellite to remain apparently stationary above the same location on Earth.
In order for a satellite’s orbit to remain stationary above the same location on Earth, the satellite’s orbital period (the time required for one complete orbit) needs to equal the Earth’s rotational period - one day. Because the satellite orbits at the same rate the Earth rotates, the satellite remains stationary above the same longitude on Earth.
In addition for the satellite orbit to be truly geostationary, the orbit must not be inclined to the equator. Otherwise the satellite will oscillate in a north south direction above the same longitude.
Just like that:
So that’s why you are able to stay connected with the satellite at all time. Now, remember when I said moving your antenna of a single degree would make a difference, well now imagine if the Earth’s axis would shift! The Earth does move, but not the satellite. There aren’t any physical bindings between the Earth and the satellite which means your antenna is no longer pointing toward the satellite. So if you are still able to watch satellite T.V., the Earth’s axis is the same.
Also, it is ridiculous to think it wouldn’t have important impacts. Just the length of days would be different! I strongly encourage you to have a look at this video as it’s pretty good to understand the basics:
I hope it cleared it all!
Zeta Report, Aliens and Nancy Leider (She’s crazy)
Posted by: | CommentsRemember Nany Leider from the website zetatalk.com? Well she’s crazier than I thought. In the following video, she talks about aliens on other planets and how they look different from us. In fact, they are either insects, mammal or reptiles. How does she knows? Well she met them. Stupid question hey?
Can you watch this without laughing?
Exploring Life’s Origins
Posted by: | CommentsI Stumbled Upon a great website I would like to share with you. The website is called Exploring Life’s Origins and the purpose of the website, as you can imagine, is to explain life’s origins. it is brought in a very graphical way which facilitates understanding and it’s aimed at everyone. There are easy explanations of complex stuff like DNA and evolution backed with videos and images. Have a look and spend a couple of minutes there, it’s worth it:
Man jumps from plane with no parachute
Posted by: | CommentsAgain, just when I thought I had seen everything, here comes this article from Yahoo News:
DUANESBURG, N.Y. - A 29-year-old man leaped out of a plane at 10,000 feet with a camera but no parachute Saturday. His body was found next to a house with a damaged roof, police said. ADVERTISEMENT
Sloan Carafello of Schenectady, who was observing on the flight, followed an instructor, student and videographer out the door, wearing no skydiving gear, officials said.
Police said they did not suspect foul play but would not elaborate.
Robert Rawlins, pilot and owner of the Duanesburg Skydiving Club, said he was flying the single-engine plane and had begun to close the door when Carafello jumped.
His body was found next to a house west of Albany.
If it’s not a suicide, I wonder how you can forget about your parachute!
Are we being a little paranoid here?
Posted by: | CommentsDo you know about the “NukAlert portable radiation monitor and alarm?”. If your answer is no, here’s a little description:
More than just a radiation detector, the NukAlert™ is a patented personal radiation meter, monitor and alarm. Small enough to attach to a key chain, the device operates non-stop, 24/7 and will promptly warn you of the presence of unseen, but acutely dangerous levels of radiation.
Used nationwide by federal, state and local first responders, law enforcement and the Dept. of Defense, the device is the ideal solution for increasing individual security and awareness of radiological threats. It will be very reassuring to know, with confidence, when you and your family are out of the worst danger.
It looks like that:
So, for the cheap price of 160.00$, you get your own personal nuclear monitor. Can someone tell me the damn purpose of paying 160.00$ for that and carrying it with you everyday? Ok, you’ll be able to tell if you are exposed to radiations…But does this happen to you very often?
Finally, here’s a little demonstration:
