- Try clicking on the various channels to see videos posted to that channel - if you're into music you can click the Music channel to get more music sifts - go on and explore! Use the "hotness" when you have opened the channel link to get videos that have gotten a lot of votes, or use "newness" to have a look at the new sifts.
  When browsing sifts you like, have a look at the Related Posts list to see other related videos, click the tags under the video title to see more sifts tagged with the same tags or have a look at other sifts from the same user in the More Posts By list. If the sifted video is in a play list, have a look at the play list to see other interesting videos the Sift users have linked together.
  Enter the Sift Lounge to chat with online sifters about anything and everything, or read interesting posts in the Sift Talk forum.
  The Top New Videos list is always full of interesting, current videos. It is always recommended that you have a look through the Top New Videos, but also have a look at these:
  - Upcoming Unsifted Videos - active video submissions that neither are published to the front page nor archived to the submitter's personal queue
- Have you seen a really funny, surprising, scary, interesting, cute or in any other way extra good quality video?
  Post and share it here - VideoSift is the best video aggregator on the Web, where we share, discuss, promote, and interact with the best videos out there on the web. Post it here, and share it with the large community of video-interested users. And - you are guaranteed to find more very good videos here already!
  Mind you, we only share videos you discover that someone else has made; if you "self link," by posting a video you have made, have posted or have interests in, you risk the ban hammer - read the posting guidelines before posting. The sift is NOT for promoting your own videos - it is for sharing videos others have made.

Why Don't We Get Electricity From Waves?

submitted by newtboy

Wave power hasn’t yet made a splash because it’s hard to use waves to spin turbines, and because the sea is a harsh place to build things.

To learn more, start your googling with these keywords:
Wave energy converter - a device for turning the mechanical energy of ocean waves into mechanical energy (flow of a substance) or electrical energy
Oscillating water column - an open-bottomed chamber filled with air and water, whose wave action moves the water column up and down like a piston, forcing the air out past a turbine
Attenuator - a long multisegment floating structure oriented parallel to the direction waves travel, where differing heights of waves along the length of the device flex the connections driving hydraulic pumps that can be connected to turbines
Oscillating body - a floating buoy that oscillates with waves, generating electricity within the buoy or by pulling on a generator or by pumping water through a turbine
Overtopping device - a reservoir filled by waves to a height higher the average nearby ocean, into which reservoir water is released, spinning a turbine
Biofouling - undesirable growth of organisms like barnacles and algae on underwater surfaces
Ocean wave - energy passing through water and causing it to move in a circular motion
Turbine - a machine for producing continuous power in which a wheel with blades gets hit by a fast-moving flow of water, steam, gas, air, or other fluid, and spins (often connected to a magnet that spins)
Induction - the production of an electric current in a wire by movement of a nearby magnetic field
