Book review: Steve Jobs by Walter Isaacson

Steve JobsSteve Jobs by Walter Isaacson

My rating: 4 of 5 stars

Beautifully written. The narrative somehow allows the reader to connect with the character, though it is quite obvious that beneath the genius lied a psychopath. Could he have done things differently (as I used to believe before I read the book)? Could he have been a better person, especially towards other human beings? I strongly doubt it. I’m fascinated by how that bloke could, on the one hand, strive to make the world a better place and to empower human kind, and the other totally lack humaneness. He did make the world a better place: I can’t imagine how dull a world without Apple products. I suppose that’s why everybody is so passionate about him. You can’t totally love him. You can’t totally hate him either. In any case you can’t remain indifferent. I couldn’t let go of the book until the very last page.

  • Interesting facts about photovoltaics. via @doctorkarl
    - The energy pay-back time (EPBT) of a complete PV system (not only panels, but also wires and electronic connexion devices) is, depending on the solar irradiation of its location, in the range   of 19 months (just over one year and a half) to 40 months (three years and 4 months) for a roof-mounted system, and from 32 months (2 years and 8 months) to 56 months (4 years and 8 months) for a PV-façade. 
    - Based on a commonly admitted 30 year-long commercial life cycle, the energy return factor (ERF) is between 8 and 18 for roof-mounted systems, and between 5.4 and 10 for façades.
    - Varying widely from one country to another, using the energy   production mix from each country, 1 single kW of PV    panels (roughly 10 square meters) can avoid up to 40 tons of Carbon dioxide (CO2) during its whole commercial life cycle – 23.5 for a façade.
