I read that book as well... one of the tangents was (paraphrasing from memory) when he secured financing from J. P. Morgan for a proof-of-concept wireless transmission tower (the Wardenclyffe tower). He then dramatically scaled up his plans without consulting with Morgan and tried to motivate this by picturing the project as a reflection of Morgans position in society -- surely you can see that only the best will do! After running out of money, he kept asking J. P. Morgan for more money for the rest of Morgan's life... and a large part of Morgan's sons life!
