40:20 What we thought what we sought to do with this book, Climate and Energy, the Case for Realism, is to bring together the work of 9 different climate scientists, including some of the world's top, people like Roy Spencer and and David Leggate, frankly, as as well as, John Christie and Patrick Michaels who sadly died just about a month after he finished writing his chapter for us, comparing climate models with the actual observations in the real world. Plus economists, environmental economists, developmental economists, looking at the impact of climate policy, not just on climate, but also on human well-being, as we switch from the abundant, affordable, reliable, scalable energy that we get from fossil fuels to the, diffuse expensive, unreliable, non scalable energy that you get from wind and solar, what happens? Well, you know, for instance, you have a 29% increase in, gasoline prices in the US over the last 4 years. That's rather steep inflation there. You you have, bigger increase in electricity prices.
