The science of heat engines was begun and nearly completed in the mid-1800s. Unfortunately, since then it took a serious left turn into nonsense, which would be okay if that nonsense was not also causing close to ten times the CO2 footprint necessary for our heat engines, whether in our cars or electric grid. Near-unanimous opinion in the scientific community says global warming is caused by humanity's CO2 footprint. Unchecked global warming could turn the major continents into deserts with flooded coastlines. So it is long past time to get the science of heat engines right. Fortunately, it's not yet too late to cut way back on humanity's CO2 footprint. Buy this book and write your congressman today
