Being new to the site, I searched for over 30 minutes for this thread only to find no discussion on the topic.
I build natural gas fired power plants for a living. Though not an expert on R&D and pilot projects, I am familiar with and hear the discussions about them. I see no logical reason we should ever run out of energy. I personally believe that before I die, we will have economically viable single home nuclear generators available that will run for years. In fact the largest obstacle to their implementation will be the federal government trying to figure out how to tax their usage. Taxing ALL future usage at the point of sale will make them wholly unaffordable.
Crash Course makes the mistake (IMO) of citing historical political decisions based on nuclear opposition as a basis for predicting future political decisions regardless of public demand. When houses go dark, factories close their doors, and the public is relegated to walking or biking, I GUARANTEE the president's pen will smoke at the speed with which he/she removes one regulation after another in his/her effort to get more energy online.
Chris has good points and I think it wise to practice many of his ideas solely on the basis of common sense. But how does the life-altering scenario play out if the predicted energy crisis doesn't pan out thereby negating the "life-altering" aspect of his solutions? Will you not have needlessly made yourself poorer?



Chris,
I have really enjoyed your presentation and have turned many people on to your Crash Course. It is nothing short of magisterial. However, I must take exception to some of your analysis in the energy chapter.
You are correct that surplus energy is declining and that costs of liquid fuel will take a larger proportion of our incomes. But I don’t believe this will be an exponential rise. When oil is priced over $50 a barrel, it can be produced synthetically using the Fischer – Tropsch process. Essentially coal is chemically united with water to release the hydrogen in water and wed it to the carbon in coal. This produces an eminently usable liquid fuel. This process was used by Nazi Germany and Japan to produce fuel during WW2, when fossil fuel was embargoed. South Africa also used the process when they were embargoed in the Apartheid era. They actually continue to produce diesel to this day.
This process requires a large investment, but if oil remains priced over $100 for long it can be economically achieved.
The four energy hogs (US, China, Russia, and India) all have massive amounts of coal. The US alone has 2 trillion tons of coal and uses about a billion tons a year. Even if we increase our consumption tenfold it will last for centuries. There are some Environmental consequences with CO2 increase, but they can be sequestered at costs that are not astronomical.

I agree that ethanol and hydrogen are probably a dead end, but your remarks on uranium seem off the point. We can run the ultrasafe Pebble Bed nuclear reactors for safe power and a smaller amount of Fast Breeder reactors to produce Plutonium for the fuel to use in them. France is doing this now. We treat Plutonium as nuclear waste for political reasons rather than scientific reasons. A Breeder reactor can double the amount of Plutonium fuel in less than ten years. Nuclear might be a tough sell to the US public, but the risks are quite manageable. When faced with a choice between a rapid fall in living standards or the small risks of Nuclear, I think the nuclear option can be sold. Also Nuclear is Green as far as Carbon output.

I also recommend that you take a look at the recently released book “Physics for Future Presidents”. It is written by Richard Muller, PhD, a Physicist at UCAL Berkeley and a recipient of the MacArthur Fellowship. It is a very readable and accessible explanation of energy in its many forms. I would hope at least one of our dumbbell candidates would also take a look.
Please keep up your truly exceptional work. Thanks for your efforts, I look forward to your next chapter.

Aleister Purdurabo
