re: Twin Creeks solar panel technology

Actually, Jacques Cousteau came up with the idea more than a half-century ago, set up trials using tidal turbines at dozens of locations throughout the world, and determined that it really didn't take huge amount of tidal flow to create lots of electricity. It all depended upon the placement of the tidal generator in relation to the normal tidal flow patterns. Cousteau's generators used relatively large, turbine blades that were well balanced and relatively lightweight. Consequently, he was able to generate a considerable amount of electricity in areas with tidal changes as little as 2 feet.

He too was concerned with the entrainment of small fish into the system and developed a fairly complex filter that prevented the vast majority of fish from entering the turbine. Keep in mind that these were merely trial runs using small systems, but with today's technology it would be very easy to duplicate his efforts on a large scale and do so at an affordable price. Jacques Cousteau, IMO, was an incredible genius who was well ahead of his time.

Cousteau made some nice films about the ideas and research of OTHERS. He did help to popularize the "aqua lung", but even that was invented by someone else.

Cousteau was very charismatic and pretty damned good at self promotion. But he was no scientist, or even an engineer.

Back to the point of the OP.

Thank you for sharing.

I look forward to the day when the US can reclaim a leadership role in solar technology MANUFACTURING...

Hopefully, the technology and manufacture will remain based in the US (for a change).

Not gonna happen without government subsidies, etc - which are of course a dirty word, these days...

Don't count on it, we'll still likely be buying our panels from the Chinese...

Twin Creeks will not be manufacturing panels themselves, what they have developed and are marketing is the machine capable of this new type of manufacture...

Quote:

Unlike other solar startups with new manufacturing techniques, Twin Creeks has no interest in producing its own cells, modules and panels. Instead, it will build its proton-firing machine and sell the device to any solar company that wants it.

"We're not a panel or a cell maker - we make big machines," said Chief Executive Officer Siva Sivaram. "Once one of them uses this, the cost advantage is going to be so large that everybody will be forced to use the same technology."

.....

The company has not yet sold any of the machines but is in discussions with several companies in the United States and China.

Re: Twin Creeks solar panel technology

Adam.. fixed the title for you..

There has been a trial run of tidal power off of Race Rocks near Victoria a few years back. I never heard how it went or if it's still in place - essentially a submerged turbine rotating in the tidal stream. Plenty of places where the water flows swiftly enough around here, but in our various narrows there would be some considerable impact in navigability and power transmission.

Re: Twin Creeks solar panel technology

If the Gulf Stream didn't shift around so much, and wasn't so far offshore, it would be a great location to place tidal generators.

Inshore, in the mid-Atlantic region, Overfalls Shoals at the mouth of Delaware Bay immediately comes to mind. Definitely not a navigational hazard, incredible tidal flow and right in the middle of one of the largest, metropolitan regions of the United States.

You could place several tidal turbines at the mouth of Chesapeake Bay at the Inner Middle Grounds, a location that is not navigable because of the shoals, but tidal flows resembling a waterfall scream through the area every day. There are several non-navigable inlets between Wachapreague, VA and Cape Charles, VA that could also be utilized. This particular region experiences huge tidal changes up to 10 feet. The volume of water passing through these inlets during a single tidal change is probably equal to the average flow of the Susquehanna River.

North Carolina, South Carolina, Georgia and Florida all have non-navigable inlets that could easily be utilized with tidal generators. Keep in mind that the generators are merely anchored to the bottom in a high tidal current location and the inlets are not dammed up like a river that uses the water for a hydro-electric facility. Therefore, fish and small boats can still pass through the inlets as they did prior to installation of the turbines.

I look at tidal generators as a far more viable solution to energy independence than solar or wind, both of which are expensive and unreliable. Those tides have been with us since time began and they'll continue to be there until the Moon crashes into the Earth. I can't think of any, more powerful, force on the planet than the ocean's tides. Unfortunately, we continue to overlook that force as an inexpensive, clean, constant, source of energy.
