We can and probably are trying that very thing, but the way plants do it creates sugars and fibers, not creating free electrons.

It's just not something that we can replicate completely for our purposes.

One thing we might be able to do is capture the carbon emissions from burning plant material, like sugars, then use the CO2 from those emissions to feed a new generation of photoelectric cells. There would probably be loses in the system, but...

I think that the biggest problem with trying to use plant-based photosynthesis for electrical power generation is that photosynthesis is the creation of sugars through the combination of CO2 and water, utilizing energy from the sunlight.

Those sugars are great for animals to produce heat energy, but not good at generating electricity directly.

Meaning, we would need to translate the sunlight into sugar, then use the sugar to generate one kind of energy, then use that energy to generate power. Each step involves a decrease in efficiency.

Plants overcome that efficiency issue by growing larger and taller, to get more sunlight. Animals overcome that issue by eating more plants or eating more plant-eaters.

Photosynthetic power plants would have to become exponentially larger to overcome three or more steps of inefficiency.

Eating doesn't give you energy right away, in most cases, and overeating often has energy that doesn't convert quickly.

Potato chips, meat, bread, rice, etc, are calorie dense, but full of complex carbohydrates and fats that need to be broken down into more simple sugars.

That process actually uses energy in the short term, before giving you a boost of energy later.

Simple sugars, like those found in juices and desserts, don't need to be broken down, and provide energy very quickly to the body.

So, what happens when you overeat? Your body shuts down to process the food, then has nowhere to go with the excess energy. That energy is then converted into fats and stored in the body for later.

Theoretically, in any group of people, the majority of the body will be average in knowledge and intelligence, and few will be outlying to the top or bottom. This creates a "bell curve", a hump in the graphical representation of the class.

If everything is done right, then the majority of students will receive a similar grade, hopefully around 70 (passing) anyway.

But if the concepts are harder, the whole class might get dragged back, putting the average grade lower, let's say 68, failing if you just grade the tests.

Grading on the curve corrects for the fact that they are doing the best they can, pushing the passing score down to 67. It allows for a teacher to fudge the numbers and allow for fewer failures for little mistakes.

But if you have a student that greatly excels in the test, that throws off the Curve. Among other things, it suggests that the subject matter wasn't all that hard and the "barely failing" students simply failed to learn the lesson.

I get that a lot. Someone will rapid fire like 5 points on Twitter (where space is limited), and I'll address points 1, 2, and 3, and they will shoot back about how I refuse to talk about point 5 before I am even done with point 4.

So, I address point 5, and they use the fact that you can't see the whole threads at once to accuse me of not addressing point 3, then fire off 5 more points.

And even if I do manage to address all of them, they just argue that one of the responses just doesn't apply in the situation, accuse me of acting in bad faith, and block me from responding further.

And in their twisted mind, that means they won.
