Whooshh transport launches salmon at 22 mph, saving lives, Ep. 170The Salmon Cannon, aka Hydrovision, is a fast and safe transport for salmon currently being tested in the wild and in commercial fisheries; and the Barak kit turns everything else into an e-bike.
[MUSIC] Hello, my name is Stephen Beacham and here's what's happening this week on CNET's Crave blog. [MUSIC] Disney is developing tops that are able to spin despite their irregular body shapes. The top spins because of its. Equally distributed, perfectly symmetrical body mass that once put into motion creates a moment of inertia, which is the rotational inertia of an object. The object being rotated has a very low resistance which allows it to spin for a long period of time. When an object is oblong. They're not evenly distributed like a teapot, for example, it will topple. The handle and the spout make it unstable. Disney's research zurick has developed an algorithm that redistributes the mass inside a 3D printed top. The mass inside the object is hollowed out. Certain areas, making the weight of the top evenly distributed and able to spin on its axis gracefully. For other objects that might be too difficult to balance because of their intricate detail and small pieces, 3D printed casts using different materials like metal are printed out. Built into the tops to help evenly distribute the weight so that they will be able to spin as well. Disney is also using this algorithm for 3-D printing oddly shaped yoyos and figures that can balance themselves in different standing positions. Electric bikes are picking up in popularity, but there's only one problem. They are really expensive. Now, e-bike builder and do it yourself enthusiast, Micah Toll, has created a solution for those of us who are too lazy to pedal ourselves. The Barak Electric Bicycle Conversion Kit allows you to electrify your bike and is currently available on Kickstarter. The kick. Comes with four easy to assemble pieces. First, you replace your bike's front wheel with a motor wheel, which comes in two sizes, 20 inch and 26 inches. Then you install the throttle of your bike's handlebars. You then connect the battery and the throttle wire. To the controller, and boom, you're good to go. The kit comes with your choice of a 350 watt battery good for lightweight riders, or a 500 watt battery for more power. There are four different versions of the Barak e-bike kit to choose from and it ranges in price from $655 to $585. Britain's Tate Museum in London is offering after-hours tours of the museum in the dark using remote controlled robots that you can operate via the internet. For 5 nights beginning August 13th, you can sign up to drive a robot through a museum in the dark. Taking in the beautiful works of art. Or telepresence robots equipped with headlights, designed by space exploration technology company RAL Space, can be steered by users to view the museums priceless works. Users will be queued on the website, taking turns steering the robot for a few minutes. I know what you're thinking, I'm gonna knock over on of those statues with my robot. But think again. The robots are not allowed to get close to any of the artwork and the interface will warn you when you're too close. There will be a live stream of the museum tours that you can watch in real time as you wait in the queue to drive your own bot, so check out the dates in the blog. Whooshh Innovations, known for their suction tube fruit transport machine, which safely blasts fruit through a network of tubes without bruising it, has been hard at work developing a salmon cannon. Actually I think it's called the Hydrovision 2014. In an effort to save the lives of migrating salmon that may get trapped near dams. And man made structures in the water. Whooshh Innovations built the salmon canon to help fish get upstream faster and easier, increasing salmon populations in the long term. The salmon cannon works like a pneumatic tube. Fish go in one end and the soft fabric of the tube forms a seal around the body of the fish, creating a vacuum, which propels the fish through the tube at a speed of around 11 to 22 miles per. Per hour. The fish pops out on the other end landing safely in the water. [INAUDIBLE] Innovations has been testing the salmon cannon in the Pacific Northwest and found that the salmon will happily swim into it on their own launching them up an incline to their desired destination, which is upstream. The salmon cannon. Obviously would be a great addition to fishery speeding up the production and transport of thousands of fish a day. [MUSIC] Alright guys. Thanks for watching the show. As always you can find all these news stories at cnets crave blogger crave.cnet.com. Make sure you follow Crave on twitter @crave.
