Can pushing the door store energy

Does opening a door increase energy?

"Opening the door" should be interpreted as accelerating the door to a certain rotational speed. My own answer is no, since the change in force would be proportional to the distance required to open the door and therefore the total energy would remain the same. You need to think of where the energy you are giving to the door is going; friction.

How much energy does it take to close a door?

It takes the same amount of energy to close the door no matter where you push on it. But when you push farther away from the hinges, you spread out that energy transfer over a longer distance (the same angular distance, but a longer actual distance).

Does door use affect energy generation potential?

The impact on the motion and energy generation potential of several parameters such as the door mass, door width and damping of the generator were considered. It was found that door use has potential for electrical energy generation. For a swing door somewhere in the region of 10 J could be expected from a single action.

Does a hinged door take more energy to open?

Assuming an ordinary hinged door (without any springs), would it take more energy to open it when applying force in the middle of the door (point b), rather than at the end of the door (point a), where the door knob is? "Opening the door" should be interpreted as accelerating the door to a certain rotational speed.

Does human use of doors generate energy?

Specifically, the energy generated by human use of doors has also been investigated [2, 3, 5, 6]. The main goal in most energy harvesting applications is to capture waste energy that would otherwise be lost or ignored. When capturing human energy, the goal is often to make the process invisible and thus not unusually burden the user.

How much electrical energy can be generated from a single door?

Experimental testing revealed that 12.7 mJ of electrical energy could be generated from a single door use, however this reduced to 3 mJ when the power conditioning was included. It should be noted that the aim was to power a sensor node, which was achieved, as opposed to harvesting as much of the available potential as possible.
