    Why not use turbine engines in cars?

    A good point. Also, my last contained BS. Sorry. Tesla did use axial turbine in combination with his turbine, but not in the way I described. In the referenced patent he describes an engine where the two are used in combination for achieving high efficiency. His turbine is "the first stage"...

    Why not use turbine engines in cars?

    Instead of compressing the input air, an equivalent of a "suction stroke" can be created by maintaining vacuum at the exhaust. For the most efficient operation of a centripetal flow turbine, you'll want this anyway, as the input fluid should never enter the turbine at higher pressure than that...

    Why not use turbine engines in cars?

    In a conventional gas turbine, yes. How about an external combustion turbine? One with discrete explosions? Have a look at the patent I linked few posts back. Designs for external, cyclic combustion gas turbines existed a hundred years ago. Sure they fell into oblivion, but that doesn't...

    Why not use turbine engines in cars?

    Turbines in power plants and aircrafts are designed for those specific applications. Ergo, to reach their peak efficiency over a narrow set of conditions. The efficiency of a Formula One engine would suck too, if you were going around 20mph. Turbines might very well be able to compete with...

    Why not use turbine engines in cars?

    When turbines were first put into cars, these were very probably the very reasons why the technology never took off. It's 2015 now, and hybrid cars are all over the streets. As discussed in the thread, 1 and 2 are no longer actual problems since the drivetrain can be electric. Materials for gas...

    Why not use turbine engines in cars?

    I'm curious about Tesla's (the inventor, not the car company) idea for a car engine. In his patent "Valvular Conduit", he describes a bladeless turbine powered by a small combustion chamber directly above it (Fig 4). The fuel gas and air would enter the chamber through special conduits that...

    Complete Removal of Matter from Space

    Imho, such area is the very definition of non-existence. If there's no mass nor energy it does not exist.

    Complete Removal of Matter from Space

    What comes to my mind is an area where there is absolutely nothing and is at temperature of absolute zero. But I'm wondering whether such area can exist even in theory.

    Why doesn't gravity speed up light?

    Gravity does not effect light because light does not have mass.

    Do Standing Waves Occur for All Frequencies?

    In your example, two speakers facing each other, there will always be a point right in the middle of the two where air moves into neither direction no matter what kind of signal is input. So the answer is yes.

    What Are Some Interesting Engineering Projects for Spare Time?

    Nikola Tesla's bladeless turbine has been claimed to reach efficiencies of over 95%. Nobody has ever come close. Try to design and build one with such efficiency, they are easy and inexpensive to make so if you do manage to successfully design one just patent your solution and live off the...

    Complete Removal of Matter from Space

    Because the scenario is absurd, it's a question impossible to answer. May I ask why you're so curious about that?

    Why not use turbine engines in cars?

    I think the main reason is the high cost of efficient microturbines. The most exciting project lately in this area, the Jaguar C-X75 hybrid car was canceled "due to the ongoing global economic crisis" (Wikipedia). I'm wondering whether low-cost solutions such as bladeless turbines are being...

    Nikola Tesla's Dynamic Theory of Gravity

    There's lots of misinformation on the subject, and almost no citations from Tesla himself so whatever I say can be totally wrong. But anyway here's an oversimplified version of what I have read: Tesla believed that all matter is formed out of "the primary substance" (not the classic aether)...

    Wireless Power? (The work of Nikola Tesla)

    If humanity had any sense of doing things right, we would still be hunter-gatherers free of the "how to run my toaster" -problem. :wink:
