Tesla turbine
Tesla turbine The Tesla turbine is a bladeless centripetal flow turbine patented by Nikola Tesla in 1913. It is referred to as a bladeless turbine because it uses the boundary layer effect and not a fluid impinging upon the blades as in a conventional turbine. The Tesla turbine is also known as the boundary layer turbine, cohesion-type turbine, and Prandtl layer turbine (after Ludwig Prandtl). Description[edit] View of Tesla turbine "bladeless" design Tesla wrote, "This turbine is an efficient self-starting prime mover which may be operated as a steam or mixed fluid turbine at will, without changes in construction and is on this account very convenient. This turbine can also be successfully applied to condensing plants operating with high vacuum. All the plates and washers are fitted on and keyed to a sleeve threaded at the ends and equipped with nuts and collars for drawing the thick end-plates together or, if desired, the collars may be simply forced onto it and the ends upset.

Coffee Filter Roses
Back in my failed former days as a window dresser, I got some good advice from Tanja, the Grand Dame of the cosmetics department. Originally from Romania, Tanja was widely renowned for her eyebrow waxing skills and had arrived at a point in her career when she only had to take one appointment a day, then happily dragged it out all afternoon. Most of the time was spent smoking and laughing and singing gypsy folk songs about beet salad, then more smoking and dispensing advice about important things like men, business, and unwanted hair. Of the many things I learned from Tanja, there are three golden nuggets that stand out; Never brush your teeth with blue toothpaste.Men with excessively bushy eyebrows are likely to cheat on their wives.Women will buy anything wrapped in roses *Women married to men with excessively bushy eyebrows should expect a lot of roses. A week after Tanja dropped that old chestnut, my new boss gave me the task of revamping a central display table. SHAZAM! Materials: 1.
Build a 15,000 rpm Tesla Turbine using hard drive platters
Here's a project that uses some of those dead hard drives you've got lying around. In the Tesla Turbine, air, steam, oil, or any other fluid is injected at the edge of a series of smooth parallel disks. The fluid spirals inwards and is exhausted through ventilation ports near the center of the disks. A regular blade turbine operates by transferring kinetic energy from the moving fluid to the turbine fan blades. In the Tesla Turbine, the kinetic energy transfer to the edges of the thin platters is very small. To build a turbine like this, you need some dead hard drives, some stock material (aluminum, acrylic), a milling machine with a rotary table, and a lathe with a 4 jaw chuck. Wikipedia has a good review article ( as well as articles about I run my turbine on compressed air (40 psi), and it easily reaches speeds of 10-15,000 rpm. I have more details on my webpage (

Project Funded! Thanks, Kickstarter backers! | Treefort Five
We did it! Treefort Five has officially been funded, and at 511%! It’s been a very busy few months getting this idea up and running and I’m so thankful for all the love and support! Backers, you really have made my daydreams a reality and I can’t wait to reward you for your support. So, what are the next steps? “So you’re over 500% funded, where’s that all going?” All of that extra funding is going toward bulk ordering larger quantities of materials for boxes (I can now order a run of 100+ rather than just 50 at a time), while also funding upcoming boxes. And after all of that, a few things to keep in mind: “So how can I keep up-to-date with Treefort Five’s progress?” And that sums it up! Thank you all again from high up in Treefort Five! - Danielle Like this: Like Loading...
Tesla turbines for highschool students
Here are some photos of some Tesla Turbines my Highschool Engineering students created as part of their studies into mechanisms and power transfer. Their brief was to investigate experimental power generation systems and create a prototype using available materials. I have provided the Task Overview below. Once the turbines where complete we tested their RPM and efficiency using a car timing light, changed and improved parts such as bearings etc and retested to see improvements in efficiency. Task Overview (scenario) Global - Tech Engineering are a socially conscious Engineering firm. The system must have the following considerations: high efficiency. made from available, cost efficient materials (preferably recycled or low impact materials). environmentally sound (no harmful by-products or toxic materials). small – scale or easily disassembled. be able to be mass produced in a standard workshop.

Student invention lets Guatemalans pump water on the go
University of Sheffield student Jon Leary was required to “make something useful out of rubbish” as part of his dissertation. What he ended up doing was transforming lives. As part of his studies as a Mechanical Engineering major, Leary spent four months in Guatemala. View all Leary developed the system while still in the UK. “The inspiration came from regular pannier racks that are used on touring bikes to carry things over the back wheel of a bike” Leary told us. The bicibomba movil was introduced with the help of Maya Pedal, a local organization that champions pedal-powered technology in the region. The mobile aspect of Leary’s invention, however, makes it attractive to farmers. Jon’s device can reportedly be made quite easily, using standard tools along with old bikes, bits of metal, and scrapped electric centrifugal water pumps. Jon’s project was funded by the University of Sheffield´s Department of Mechanical Engineering and Engineers Without Borders.

A 3D printable AEP7 laser pistol (Fallout)
A fully 3D printable version of the AEP7 Laser Pistol from fallout 3 and New Vegas. It can be printed in around 30 hours and requires 1kg of material. It requires a lot of support and is challenging to print, but the pay-off is most certainly worth it. All the files to build it can be found at my thingiverse page It was painted using acrylic paint and weathered with a small paintbrush and black paint. It has a working laser diode (else it wouldn't really be a laser pistol).
