&gt; Sure, but if you&#x27;re going to holistically include the cost of the science in the comparison price per KWh you should also balance it against the cost of dealing with the consequences of sustained carbon emissions from other types of power generation.<p>Guess what? They all still beat fusion hands down. Think of all the cows that farted and then died to feed the researchers. Think of all the carbon emissions generated by the actual research. Think about the real, actual return we have today.<p>You seem to be banking on the fact that we actually CAN produce an efficient fusion reactor in the near future. Total efficiency of our investment is very, very, very dependent on how fast it can crank out.<p>Now compare it to military investments and you might get somewhere....<p>EDIT: if you disagree, I&#x27;d obviously love feedback. It just seems silly to think that fusion is at all something we can depend on being able to pull out of our ass. The manhattan project was never a sure thing.
