But the US already has airbases in Greenland and northern Canada... so taking those countries over would surely be less useful or cost-effective than investigating the feasibility of an ice-classed carrier battle group. 2025-06-13T10:43:12Z https://njump.me/nevent1qqsrj3kemrcwv2a9s6el8wvkcrgtcukcxhxwqpscy943k33jm84990qzyq3zcx0mmjgxxqenj4k45nmmmfx97p9fel6498r63krcr2dg480nuqcmsp2 In reply to <a href='/nevent1qqs8ae9maxy0kyuwhmwk7hku7dhucs7n33ea0al63a247hjn82zzztc258sw8'>nevent1q…8sw8</a><br/>_________________________<br/><br/>Assuming there is rational reasoning here (obviously not always the case), then the only reasons I can see for wanting Greenland or Canada are (a) To profit off charging vessels for passage through &#34;internal waters&#34; on northern routes (I *think* this would only apply to Canada, but not sure); or (b) If you expect to become such a pariah state that you are unable to negotiate for access to natural resources in those places.<br/><br/>(not an expert though) 2025-06-13T10:18:37Z https://njump.me/nevent1qqsfdfgxvl0guzwnp8xclvgc45dnhmf05cnac9lh79sk96l48nlf0qczyq3zcx0mmjgxxqenj4k45nmmmfx97p9fel6498r63krcr2dg480nu2anjsj In reply to <a href='/nevent1qqs8e9ksft34rcal0ymwwdcyj256cyz5wqkrqw734nsvq7nrmln59aqygktev'>nevent1q…ktev</a><br/>_________________________<br/><br/>I&#39;m curious about how Peertube instances will cope with the costs of storage and bandwidth, which I imagine will be substantial compared to Mastodon and similar.

Because while Mastodon and similar servers seem to get by quite well with crowdfunding and volunteer effort, any but the smallest Peertube instance is going to need extensive storage and probably (depending on how it works) bandwidth. Both of which cost.<br/><br/>What am I missing? 2025-06-09T11:05:47Z https://njump.me/nevent1qqsf72mucjsxnh3f0mmfkm659ld263npc3m35pzqj3wdmwljaqpfl2gzyq3zcx0mmjgxxqenj4k45nmmmfx97p9fel6498r63krcr2dg480nuhacuf9 Looking for a live map of UK #power cuts.

That won&#39;t change for any sensible amount of money. Hywind is a technology demonstrator, but for a fully commercial project this might be a factor in not using that particular design off Scotland! The Kincardine farm uses a different platform which needs much less water depth. 2024-08-25T15:33:32Z
