Developing Prospects for Oceanic Geothermal Energy Conversion

By Harry Valentine 05-09-2021 11:27:10

While the earth’s core is believed to be molten material, the majority of the world’s active volcanoes are believed to be releasing vast amounts of thermal energy on the ocean floor. Accessing that thermal energy and producing electric power would require significant advances in existing deep-sea ocean thermal energy conversion (OTEC) technology. Introduction The combination of recreational and commercial diving revealed a difference in temperature between surface seawater and deeper seawater in tropical regions. While surface temperature of over 95...

By The Strategist 05-09-2021 06:18:29

  There’s rising concern about the prospect of a major military crisis erupting across the Taiwan Strait as a result of China’s intention to force Taiwan to unify with the mainland. President Xi Jinping suggested in early 2019 that China must be and will be reunified, and noted, "It is a historical conclusion drawn over the 70 years of the development of cross-Strait relations, and a must for the great rejuvenation of the Chinese nation in the new era." He went...

Korea Adds Hydrogen Plant as it Approves Giant Floating Wind Farm Plan

Plans for Korea’s first large-scale floating offshore wind farm, proposed to be the largest in the world, cleared a key hurdle while a consortium of Korean companies also announced plans to add a plant to produce green hydrogen to the project.

VSM: Asian Shipbuilding Subsidies Put German Shipyards at Risk

German shipbuilding association VSM is warning of the risk of an "irreversible loss" of skill in the country's powerhouse marine equipment and shipyard sectors due to distortions in international competition. Without government intervention at the national and EU level, warned VSM, Germany's yards run the risk of significant decline over the next decade. Like others, German shipbuilders have been losing ground to Asian competitors for general-purpose merchant vessels for many years, and the sector has been sustained by specialization in...

What Are the "Internal Waves" That May Have Sunk the Sub Nanggala?

[By Callum Shakespeare] Last week might have been the first time you ever heard of “internal waves” - the phenomenon suspected of causing the tragic sinking of the Indonesian submarine KRI Nanggala the previous week, resulting in the deaths of the 53 crew members. So it may surprise you to learn that you’ve doubtless encountered internal waves before. They exist all around us in the atmosphere and ocean, although they are usually invisible. If you’ve ever been on an aeroplane experiencing turbulence, you’ve...

China's Climate Policy Has Major Implications for Trade

[By Stephen Minas] Diplomacy is not always diplomatic. This fact of international life was on full display during the recent meeting of top US and Chinese diplomats in Alaska. It has also frequently characterized the long-running United Nations climate negotiations – often with the same protagonists. A Chinese official’s declaration, prior to the ill-fated Copenhagen summit, that developed countries “would be getting a bill for a hundred years” of climate change is indicative of both tone and content. Underlying these confrontations...
