Yes. It also works with incompressible flows. I have yet to give mine a test with water. I want to build an acrylic window for it first, and ink the incoming water.

Well. Describing our ideas without a diagram breaks down rapidly. I imagined a valve bobbing in the water, slowly elevating the water in a reservoir with each wave undulation. Thin…

Tesla was an amazing man. Though our tools are impressive, I am still far more impressed by the human mind. A good use of tools relies on the exploration of consciousness. If both …

That's a good idea. I've seen some of the wave generator concepts out there, and everyone seems to be trying different concepts for harnessing those oscillations. No one has it nai…

I have done lots of experiments with 3D versions of this valve. I even did some with a traveling rotation along the axis, so that it looked like a helix. Unfortunately, those were …

1. All one-way valves depend on flow. If there is a higher pressure from A to B. And that's the direction of resistance, then in a valve with moving parts, a ball or diaphragm of s…

The current use for Tesla Valves is in microfluidics. On the macro level, people generally use one way valves that have moving parts. To harness the flow of a fluid being acoustica…

If you are still waiting for that day, you can get the valve 3D printed now from my shop: http://www.shapeways.com/model/292339/tesla_valve.html And if you already have a 3D printe…

In will work in many regimes. In the microfluidic literature, the valve is judged by its diodicity. Different flow rates, sizes, and viscosity, results in different geometry for th…

My jet engine is unique. There are actually many no-moving-parts jets. Each with different drawbacks. A ramjet cannot start from a static position, mine can start from a static pos…

Someone did a TIL on reddit and I popped in to answer questions there, too. http://www.reddit.com/r/todayilearned/comments/obyxj/til_tha...

In regard to a fractal design being more efficient, you have to check out these topology optimized valves. They are really beautiful and peculiar, and have many branching channels …

The Tesla Valve is a leaky valve, which is why we still use one way valves with moving parts. The amount of leakage depends on the design of the valve and how well it suits the inc…

I find that device fascinating too. That's why I designed the 3D printed Tesla Valve in the article. Things with no moving parts are amazing. Especially the esoteric ones that seem…

I'm the one who made that 3D printed Tesla Valve shown in the pictures and video. I'm currently inventing a jet engine with no moving parts. If anyone wants to ask questions about …

Agreed. I think that was Cringley's best point, and also why I sometimes get frustrated in the valley. Some people say they like ideas here, but what they really like are startups …

I am an author and have a book distributed over Kindle. People who bought my book wanted to buy it, and people who pirated it wanted to get it for free. That's okay with me. The tw…

In a way you are both right. There are currently two aspects of the American space industry. One, the moribund aerospace giants that are largely just making the same old rockets, e…

I was asleep when all of these replies came in. And I had it set for me to approve all comments because I had been getting spam. I approved your reply just now.

I just canceled my Facebook account today, after thinking about it for some time, and specifically in reaction to recent events. The type of decline illustrated in this timeline is…

Thank you for posting this. In light of the recent stuff that Facebook has done, I'm deleting my account. I'm glad I'm not alone in seeking the information on how to do that exactl…

You have to be careful with something like this because you might be clinically depressed. I developed anxiety and depression when I was in college. Part of that was a feeling I wa…

Whether others seem interested in the idea. I have only recently started projects that random strangers have sought me out over, and it is encouraging. Also, the feeling of a wheth…
