Non-fiction can be wonderfully entertaining (particularly periods such as the War of the Roses where so much happened in such a relatively short period) but some people like even more entertainment and so we have historical fiction (generally the emphasis is on fiction so take the history with a pinch of salt) for those people with regards to the War of the Roses can I recommend The Sunne in Splendour by Sharon Penman.
Not a lot of point in arguing when you are essentially correct, however if you are really looking for argument I'd say that your potential userbase of just aviation is slightly narrow as there are other areas I can see it being used though I am in full agreement on its not really going to be a mainstream energy source. In terms of other uses I am thinking things like some heavy plant, some heavy haulage (this more to do with max weight limits and current battery tech being heavy).
