Izumi claims their run-of-river turbine is cheaper than grid power
A Slovenian turbine-generator that is designed to work in relatively slow and shallow moving water
supposedly could not only provide clean energy but at a price point many times
cheaper than the cheapest grid power presently available.

Slovenian inventor, Vladimir Markovic, is not bashful about touting the virtues
of his run-of-the river turbine design, which he thinks can come in 70 times
cheaper than solar and wind, while being far more reliable; and 7 times cheaper
than grid electricity in Europe where he resides.
Though that optimism is probably borne of the "my baby is the most
beautiful baby" exuberance that is common for inventors, the design has
been given thumbs up by our New Energy Congress, listing it among the "Top
100 Clean Energy Technologies." Back in October of 2008 when we first
learned about this technology, then New Energy Congress member, Mark Dansie said
of it: "If manufactured using modern materials and production methods, this
is real top 10 material. I did some math, and replacing the pumps with
sealed submerged genset could supply huge volumes of electricity at install
costs less than wind turbines."
With the water, sand, rocks and other unfriendly environment found in rivers,
it's hard to imagine that a river-borne turbine system could produce electricity
more cheaply than what one can presently get from the grid. Markovic told
me "all driven units, pumps, generators or other elements are closed and installed in
a central drum, which is placed inside of a concrete plate. That way, all driven parts are
securely protected against pieces of wood, gravel and other dirtiness which can be present in the river."
The company has recently presented a new video, which they have allowed us to
post on our channel; and they have prepared a document
explaining the math and logic of the design. In uploading this video,
which originally didn't have any audio, I randomly clicked on a music track that
YouTube had in its offering, and it turned out that the audio I first selected
matched up very well with the visual elements in the video.
Regarding his latest generator design, Marcovic told me (slightly edited):
" I actually produced [it] based on standard industrial parts (for piston pumps for water or
air, etc.). Practically, I am not patent protecting centuries known designs of solenoids and magnets, but actually only the systems of driving at least three solenoidal units as one integrated solenoidal generator
in such way that everything is offering constant electric tension and operates even with
the smallest number of driving revolutions. The electrical results we have reached are excellent, because everything even calculated to operate with
[as low as] only three or more revolutions per minute."
The company is entertaining licensing agreements for deploying the
