There is a fair amount of background on what Shinra is doing post-meteor, but none of it pertains to revenue, unless I'm missing something (I never actually finished DoC - I've only read summaries). According to the novellas and what I know of DoC, Shinra provides substantial financial support to the WRO and provides Geostigma medication as a public service. They built a monument, provide medical services, attempted to perform research on Geostigma, and procured some of their original staff. Thanks to the Turks, they managed to secure some assets when the meteorfall chaos ensued. They appear to still be a fairly formidable company in spite of their massive losses. Aside from perhaps liquidating some of their assets, I'm wondering how they are generating income. What is/are their product(s)/business? Spreading thin on random projects and relying on liquidation is not a great business strategy, so I think it's safe to assume that alternative energy sources are a major and obvious source of interest, but I don't recall any of the novellas actually making reference to Shinra's source of income or Shinra involvement in other forms of energy, such as oil. Do we even know where Edge's electricity comes from?
