A Broker's Perspective on REC Trading
[LESS INFO] 1 VIEWS | ADDED 02:24:00 11/21/10
Charles Segerman, director of REC broker Clean Currents, tells Daniel Goldstein what happens when customers buy renewable energy credits from his company. Segerman says Clean Currents tries to educate businesses about green power - and the fact that they have a choice to buy it. He says many aren't aware that they have a choice, and that they can further select what type of green power generation they want to pay for. He says RECs can be bought through the company's Web site. He says the energy business is a wholesale-to-retail operation. The customer is selecting the wholesaler. RECs essentially support a wind farm - one that is somewhere in the grid and offsetting the energy generated by a non-renewable source. Basically, it's a financing mechanism for generators like wind farms. Segerman says each REC has a tracking number that allows for third-party organizations like the Center for Resource Solutions to verify that RECs are retired and not re-sold. He says as more people pay for RECs, it indicates a higher demand for green power, and that utilities should, in turn, buy more of their power from renewable suppliers. Segerman says its unclear whether consumers will demand more wind or solar in the future. He thinks customers want choice, but they are also concerned by the aesthetics of wind - the noise or the sight of wind turbines. Others are attracted to solar power because it offers on-site generation, where it's more likely that people can generate all their own power without using the grid. He says next big breakthrough could be battery storage, which can supply power when wind and solar generation aren't practical.

Samarai Roadable Vtol Helicopter Concept
[LESS INFO] 29 VIEWS | ADDED 08:56:15 01/24/10
This vehicle attempts to achieve full electric redundancy, including the event of a blade failure. It is named after the Samara (a single blade rotor - or Maple seed), attempting to integrated several of these counter weight balanced single rotors into a platform. Six blades is the minimum number of blades while being able to maintain control about all axes, with any single blade being able to fail.. It also tries to take advantage of highly responsive electric rpm change to eliminate cyclic and collective blade control. The animation shows some of the basic principles of this concept, as well as a low noise transition. This concept utilizes 400 ft/sec tip speeds, with high solidity blade/wing panels. The blade/wing panels are positioned so the structural loads are mutually sized for both rotor and wing panel bending moment issues. This vehicle would integrate new technologies, such as laser scanners for the front blades that can prevent blade strike by watching for any blade strike possibility, and take advantage of the ability to stop a single blade very quickly (on the order of 1 second) since the electric motor can also be used as a brake. While highly compact, we have already shown that the Oswald efficiency factor is greater than 1.7 through a vortex lattice analysis, due to the highly non-planar triple wing layout (so while the vehicle can fit in an 8 box with blades inward the effective span at cruise is 20. The discloading is only 6 lb/ft2 for this concept (assuming a 1320 lb weight for 2 passengers), so the power required is quite reasonable, while avoiding the slow cruise speed of rotorcraft through this stopped-rotor implementation. This concept is a hybrid solution, with a cruise engine (Rotax 914) in the back that also provides power to an alternator at hover, to minimize the batteries required. This vehicle has a sizable range, not like the fully electric tailsitter.

Twitter Vs Facebook Round 2
[LESS INFO] 8 VIEWS | ADDED 04:32:09 04/09/09
Hello, and welcome to Thursday. This is Mevio Tech. Brooks and Carlos bring you the top tech stories of the day.
Starting off...the Facebook/Twitter battle of the ages rolls into round two, as a new desktop client has thrown its hat into the Twitter ring. Seesmic Desktop is a new desktop Twitter client from Seesmic (the same company who also released the popular Twhirl Twitter client). It seems to be positioning itself as a rival for Tweetdeck . It has a very simple design, but it's best feature is the ability to use multiple Twitter accounts, which a lot of people have been waiting for in a desktop Twitter app.
Speaking of Tweetdeck , they have also released an update to their desktop app. It adds many new functions and fixes, especially in the area of resource management. It is now not so much of a memory hog. It has better support for short urls, and the feature that warms Brooks heart: better integration with Facebook without having to jump through complicated hoops.
Moving on to Facebook , CEO Mark Zukerberg announced on his blog that Facebook has now reached the 200 million user milestone. Along with the post, he release a video and a heat map showing the growth of Facebook as more users joined, where in the world they were joining from, and how they are using it.
This round seems to have ended in a draw again. We will see who will ultimately reign supreme.
Moving on... GM and Segway recently announced a joint collaboration to create a two-person urban mobility vehicle, named P.U.M.A. , or Personal
Urban Mobility & Accessibility. The vehicle seats two people, is battery powered and will run 35 miles on a single charge, and has a top speed of 35MPH. In the end it is basically a two-person Segway, but with a steering wheel. It might be nice, but I would love to see it try to deal with some of the hills here in San Francisco.
Brooks and Carlos wrap things up with a story about quantum computers, which for the moment are still out of our reach technologically. A group of designers and developers have come together to discuss where they would need to go, and have come to the conclusion that we would have to fundamentally change the way that software is written when the time comes.
That is all for the top tech stories today. Hey while your hear, you should go over and check out our other great networks: Men, Women, and Music. And remember you can always find more great stories about the latest in tech, video games, and much more right here at Mevio Tech . Also if you like what you see, then follow us on Twitter by going to www.twitter.com/meviotech . Let us know what you think, what you like, or anything you might like to see on the network.
So have a great Thursday, and we'll see ya tomorrow.

Home Movie Cameras
Movie cameras, although available before the Second World War, had an upsurge in popularity in the immediate post-war period giving rise to the creation of home movies. Compared to the pre-war models, these cameras were small, light, fairly sophisticated and affordable. Whilst a basic model might have a single fixed aperture/focus lens, a better version might have three or four lenses of differing apertures and focal lengths on a rotating turret. A good quality camera might come with a variety of interchangeable, focusable lenses or possibly a single zoom lens. The viewfinder was normally a parallel sight within or on top of the camera body. In the 1950s and for much of the 1960s these cameras were powered by clockwork motors, again with variations of quality. A simple mechanism might only power the camera for some 30 seconds, whilst a geared drive camera might work for as long as 75 - 90 seconds (at standard speeds). Even today there is a market among collectors for these types of camera, as the engineering and materials were of a very high standard. Whilst film stock, and the ability to process same, exists these cameras can still be used.
In the 1960s a new film format, Super8, coincided with the advent of battery operated electric movie cameras. The new film, with a larger frame print on the same width of film stock, came in a cassette which simplified changeover and developing. Another advantage of the new system is that they had the capacity to record sound, albeit of indifferent quality. Camera bodies, and sometimes lenses, were increasing made in plastic rather than the metals of the earlier types. As the costs of mass production came down, so did the price and these cameras became very popular. This type of format and camera was more quickly superseded for amateurs by the advent of video cameras, although some professionals continued to make use of its visual characteristics alongside larger format film and video cameras.
One of the continuing problems in film is synchronizing a sound recording with the film. Most film cameras do not record sound internally; instead, the sound is captured separately by a precision audio device. This is called double-system. The exceptions to this are the single-system news film cameras, which had? magnetic recording head inside the camera. A smaller balance stripe existed between the perforations and the edge to compensate the thickness of the recording stripe to keep the film wound evenly.
Since editing sound was very limited at that time, life sound unfortunately in this film is interrupted at every scene change.
