Also I notice Cr-Steel's elastic yield strength at 400C is about 87% of its strength at room temp and I don't think it does alter significantly over these timescales at that temperature. It will be interesting to see how high it

I've never found it well argued that appeals to nature are inherently fallacious to any good philosophical or logical standard. The common advice that they are fallacious has always struck me as ideological with explanations relying on

Does this case extend to general advice though - that people should stay invested in fossil fuel companies in order to regulate them a bit? It should follow that if we invest more in fossil fuel extraction we can regulate them more. It seem
