It’s about time people got a memo about what the French got right. Yes Nuclear Energy, a nuclear power grid. It’s about time America got more nuclear too.

Come on folks, nuclear energy is the future! WHY TRY TO GET AROUND IT?!!!!

Doesn't the making of ethanol...( The actual distilling, or whatever they do...) take energy of some sort? Isn't that the point they are making?
This is correct. Studies in the US have shown that the net-energy expense is either equal or exceeds what it takes to produce ethanol, truck it to refineries, add the right mixture, etc. And then there's the separate issue of how taking corn out of the food supply and pouring it into our gas tanks artificially inflate food prices -- all done with enormous taxpayer subsidies to the ethanol industry. It's a sick cycle.

It just gets better and better, doesn’t it?

I’ve noticed lately that there is less and less talk about “global warming” and “climate change”. The BS is starting to dissipate, even though the slimestream media doesn’t want to report on the discoveries of all the fraudulent claims, the vast amount of money that was intended to be sucked out of the populace and basically what was the grandest fraud/scam ever attempted. It’s the story of the new century, yet what do we hear from them?

Crickets.

It ain't about biofuels, it's about gov't programs -- the latter are not designed to actually accomplish what they're said to be for, but rather to put some money in certain people's pockets. :') Thanks Ernest.

The actual energy for distilling is relatively low because of the use of heat exchangers.

What does that mean?

The heat input to the heat exchangers is energy and has to come from somewhere.

The energy input lasts a long time and distills quite a bit of alcohol or whatever you are processing out of the biofuel mass. It's quite efficient compared to the country still making moonshine that we often visualize.

So you are saying the fermentation creates heat that is then recovered and used in other areas of the process, if I read that correctly.

Not quite. Fermentation only produces a little heat, too little to recapture profitably. It's distillation that allows for reusing the heat through a regenerative heat exchange system. As alcohol-free liquid flows out, it pre-heats the alcohol-laden fluid that is ready to be distilled, cooling to room temperature as the fluid is heated to near the boiling point with negligible loss. The design is copied from nature:

"Counter Current Circulation": Arctic animals try to keep their temperature constant, but their legs remain cold, while their head and body core remain warm. This seems like a difficult feat, but with an adaptation called countercurrent heat exchange it requires little energy. In this system of circulation arteries, which carry warm blood from the heart to the extremities, lie very close to the veins, which carry blood from the cold extremities of the body back to the heart. In this way, heat from the warm arterial blood is transferred to the colder blood in a vein, thereby cooling the blood in the artery and warming the venous blood. Thus, as blood from the body reaches the extremities, it is already cooled and loses very little additional heat to the environment. Conversely, cool blood from the extremities is warmed prior to reaching the body core and does not shock the heart or reduce internal body temperature. The countercurrent exchange system has been well studied in both the arctic fox and the caribou, which maintain their core temperature nearly 30°C higher than their appendages.

"Well....now what?"
I could asked the same question.
