Today, we're very dependent on cheap energy. We just take it for granted - all the things you have in the house, the way industry works.

Having kids has been a fantastic thing for me. It's meant that I'm a little more balanced. In my twenties I worked massively, hardly took vacation at all. Now, I, with the help of my wife, I'm always making sure I've got a good balance of how I spend my time.

Our modern lifestyle is not a political creation. Before 1700, everybody was poor as hell. Life was short and brutish. It wasn't because we didn't have good politicians; we had some really good politicians. But then we started inventing - electricity, steam engines, microprocessors, understanding genetics and medicine and things like that. Yes, stability and education are important - I'm not taking anything away from that - but innovation is the real driver of progress.

You need to understand things in order to invent beyond them.

I choose a lazy person to do a hard job. Because a lazy person will find an easy way to do it.

We should all grow our own food and do our own waste processing, we really should.
