Its 3500km to the nearest large population centres (northern China) that could absorb that sort of energy so transmission as electricity unlikely. 2500 km to Hokkaido Quote Share this post Link to post Share on other sites

More like 20km Has anyone done a serious estimate of the costs? The Tidal barrage in S Korea is about 7km long and cost $560m Quote Share this post Link to post Share on other sites

Andrei Moutchkine + 828 July 12, 2022 Just now, NickW said: Neither the South Koreans or Japanese want to be subject to energy blackmail. Ie - agree with us or we cut off the supply. There is no energy blackmail, it is a European invention. The current reduction in the flow rates on the North stream is due to Canada impounding the Siemens compressors during the maintenance. Otherwise, pipeline sales work similar to LNG ones. Don't buy if you don't want any. Both Japan and Korea already buy a lot of Russian LNG and coal.

Average water depth is over 50m. + you have to get down to bedrock to make a seal. In essence this is an order of magnitude larger than the largest dam in the world and you are working in the ocean. It is why most do NOT recommend trying to build dams for tidal power but rather multitude of other forms such as forms of wiers. Quote Share this post Link to post Share on other sites

The dam is to be made from prefab blocks housing turbines, which are loaded with ballast and sank where they need to be. Quote Share this post Link to post Share on other sites

According to wiki the proposal for this tech in the Sea of Okhotsk is called Tugur and from what I found is only 6.8GW. Much smaller than either of the Penzhin proposals.

It is still just as stranded, though? They have developed a standardized prefab block, containing a widget called the "orthogonal turbine" which has the property of being orientation-independent. https://www.hydropower-dams.com/articles/the-new-orthogonal-turbine-for-tidal-wave-and-low-head-hydropower-plants/ Most of the documentation on it is in Russian, but the general idea of it appears to be similar to those wind turbines that look like eggbeaters and are oriented vertically, if you have ever seen any? It probably does not have to be fully dammed, either. They had some kind of trial with an Australian company called Atlantis, which appears to be in the "tidal stream" business.

It gives you some electricity, but is obviously less than perfectly efficient. I see that it is useful to start producing energy before the location is fully dammed.

Pretty hard to have traffic without cars... Nor is a citizen allowed to own a chicken or a cow... It is like Cuba's "free" Health care... Bring your own sheets, antiseptic to clean everything, gauze, and light bulbs otherwise the operation will be done in the dark without any antiseptic.. Of course you can't buy antiseptic, gauze etc, so... Good luck 1 1 Quote Share this post Link to post Share on other sites

Have you ever been to Cuba? The average "house" is a very poor run down shack There are no traffic jams because guess what there are no cars and even if there were the people couldnt afford to buy or run them. To get to work the average person has to walk to an intersection and wait for a government vehicle to stop and take them to their place of work (they have to stop by law). If no government vehicles go by then they just walk back home! the vast majority of vehicles are privately owned coaches taking vacationers to their hotels, they dont have to stop and therefore dont. The only person to benefit from Castro's coup was Castro and he became a billionaire based on Cuba's original wealth and watched his fellow citizens languish in abject poverty until he died! Free wifi haha nobody owns computers, if they work for the government wouldnt you expect that the employees didnt have to pay for the wifi they need to do their job??
