: 'Proposal to combine (1) Nicola Tesla's "Valvular Conduit", patented in 1920, which is essentially a one-way fluidic valve, and (2) the Anaconda Bulge Wave concept of having rubber tubing move up and down with ocean waves, in order to provide a simple and cost-effective mechanism for harnessing sea wave energy.'

Combining Two Great Ideas

In reading a biographical book, Tesla: Master of Lightning today, I came across his "Valvular Conduit" diagram, patented in Feb. 3, 1920 -- one of his last.

Then this evening I received an email suggesting that I interview someone from the Directory:Bulge Wave Anaconda by Checkmate Sea Energy project, in which a rubber tube in the sea propagates bulges through the tube with the movement of the waves.

As I looked at their diagram, I immediately thought of Tesla's patent that I had seen earlier. "What would happen if you implemented Tesla's Valvular Conduit into flexible material so it could undulate with the waves?" I wondered. I would think that it would create a strong pumping action in one direction. One end of the tube could be attached to the input of a turbine, with the other end attached to the output of the turbine, in a closed loop. The turbine would be on land or on a platform at sea, while the tube extended out into the waves of the sea.

The fluid in the tubes could have high lubricity (while also being environmentally benign) so as to promote longevity of the turbine.

Alternatively, a Tesla turbine could be used, and what flows through the valvular conduit tubing could be an inert gas.

This would be particularly feasible if there could be some way to easily mold the Tesla Valvular Conduit pattern into flexible material such as rubber.

The tubing could even be arranged somewhat like the artery-vein system of a warm-blooded organism, going from large to smaller and smaller tubes, then coming back to larger and larger tubes where it meets the turbine. The tubes could be made to look like Kelp, so they blend in with the sea.

Open Source

In publishing this here at PESWiki, I am hereby open sourcing this renewable energy idea, opening it up to the world community to ponder, test, improve, and implement.

As good models are developed, we can list them here, along with the component parts, so they can be replicated and commissioned.

The objective will be to come up with as simple and powerful a system as possible that makes the system easy and inexpensive to build, install, and operate.

Third Idea for Low-Head Stream Aps

Dear Sterling,

I recently stumbled across your interesting proposal

to combine Nicola Tesla's "Valvular Conduit", which is

a one-way fluidic valve (has it ever been prototyped?)

with the Anaconda Bulge Wave concept of flexible

tubing which moves with ocean waves - for harnessing

sea wave energy. That does make a lot of sense, if one

is near an ocean.

If there has never been a prototype of Tesla's valve,

however, it is unclear what net pumping pressure is

added by the wave action but on first blush, it could

be substantial.

However, it occurred to me in looking at the proposal,

and beyond that to mental images of land-based

alternatives - that your basic system may not be

limited to sea wave energy.

Think of the concept as being transposed to a low head

creek or stream. Obviously low-head streams do not

have waves and yes- there are available some low-head

turbines which are increasing in efficiency. In the

end, it will be how much bang-for-the-buck is

available, as always.

In the spirit of open-sourcing, let me try to

verbalize what could be a "third idea" for combining

the previous two with the addition of "virtual waves"

which are supplied by a slight elevation drop on land,

and some simple earth-work.

First to backtrack: On you site, of course, is the

"Directory:Zotloterer Gravitational Vortex Power Plant" which is

one solution for low head streams. But that one is not

low cost and involves a fairly substantial investment

in precision concrete casting and probably requires

non mass-produced generator equipment (due to the odd

intermediate sizing).

As an alternative to this kind of low-head dam, which

is still a dam (and which are government regulated

since there is always risks with any dam) there is the

modified spillway. By this I mean simply a man-made

channel or passage which does not even need to be of

concrete. This would alter a short stretch of an

existing stream or creek in a risk-free way, which

avoids the definition of "dam".

The "virtual wave" part is simply a result of the

contouring of the underlying ground - with

packed-earth or covered with "shotcrete" form

permanence, in the form of permanent low-crest

standing waves.

As long as there is some drop (head) along the way,

then these stationary waves operate as "virtual", and

could provide a pumping action when combined with the

Tesla valve (T-valve). The underlying wave contours

need simply to support a number of flexible tubes

(such as an array of converted fire hoses) which are

spaced periodically with the one-way T-valves. Perhaps

one short section of T-valve is located in every

through for every tube along the way.

The hope, and it is only that as of now - is that the

net effect of the combination would be a cheaper

version of a low-head dam, and one which is

unregulated, yet possibly having higher effective

pressure at the venturi than would be suggested by the

elevation alone, due to the one-way pumping action of

wave acceleration.

Plus this design could implement the mass-produced

molded pelton-type tubines which are now available at

a fraction of the cost per unit of power of expensive

one-off turbines. The T-valve also should be mass

produced, as well.

I could imagine a situation where most of the flow of

a small creek is being fed into an array of perhaps a

dozen sections of flexible fire hose, which are placed

over artificial "waves" with a low head, and each hose

having a small generator at the end, T-vales upstream

and dumping the water back into the same creek bed in

the end - but at a downstream location- possibly

short-circuiting a natural bend.

Anyway - just more food for thought until the T-valve

is actually prototyped and tested. Every kW-hr of

non-fossil, non CO2 energy helps in so many ways and

the open-sourcing of many of these hydro and wind

concepts may expedite that goal.

Right here. This idea of implementing the Tesla Valvular Conduit into a wave-riding tubular system originated here at PESWiki.
