I want to ask about trees?

Question

Can this trees can make frie energy? I think putting a wire that are connected to the branch or near the leavs?Will it make energy?

How about banana trees?

How about sand in the desert at the surface of the ground?
and also cactus plant?

What i ment about the sand is the heat of the ground?

Answer 1

That is a very good idea in theory, however it would not work. You could not possibly gather electirical energy from a tree for the sole reason that it does not produce any.
All living organisms need some sort of energy to live and grow, but not all energies are the same.
The type of energy that a tree uses is call ATP. It is the most common form of energy that is used by living things.
A tree gets its energy from a process called photosynthesis. you've probably heard of it. The magical little dealy where plants get energy from the sun? Well here's how it works. Inside a cell of a tree, a part of the cell (or an organelle) called the chloroplast, combines 6 molecules of CO2 (carbon dioxide) and 6 molecules of H2O (water) and uses the enery from the sun to combine these in a chemical reaction. The result is C6H12O6 (glucose, that's sugar to you and I) and 6 molecules of O2 (oxygen). After it has made this glucose, it uses it in another process in another organell (the mitochondrea) called cellular respiration. Here it takes the glucose (C6H12O6) and combines it with oxygen (6 molecules of O2) to produce 6 molecules of CO2, 6 molecules of H2O and finally the whole reason it's been combining things in the first place... 36 ATP energy. This energy is not the kind however that you use to power your computer though, that is electrical energy. Nice originality though, keep it up and some day you might save us all. =]
