what about bio engineering muscle cells that produce more power per volume by using a type of myosin that produce more power or even a new man-made type of myosin that the new bio engineered cells could produce on their own?. is there any discovery about types of myosin that produce more power...

We can increase tendon thickness and muscle density or may be even improve their composition. Can we do the same with the cartilage of joints?. Can we potentially make a molecule or some kind of nano stracture/machine that carries oxygen more efficiently than hemoglobin?, may be we can do the...

what exactly is the difference between slow twitch and fast twitch muscles in terms of stracture?. From what I read fast twitch muscle fibers are larger, so their greater force production is because they are larger?. If we make muscle fibers larger their force production will increase?.

I see that chimpanzees have simillar levels of muscle types iia and iid(is this also called iix or iib? accodring to other articles there are 3 muscle fibers: type i, type iia and type iib which is also called iix) and from articles I read type iix produce more force than type iia and in...

I know this is a hypothetical question, but we can still have a general idea for how we could do it in the future. I wonder how theoretically with good enough technology a human can achieve a super-human strength(or close to it) without large muscles or non-biological components attached to...

i am considering learning in the university(technion) for something related to science, i am trying to decide between electrical engineering and materials engineering. also in the field of electrical engineering i saw that there is several routes on the subject in the university i want to learn...

i ALREADY readed that and i already asked "does triboelectric generator are just somekind of piezoelectric generators that work with much less pressure?" which means that i aware to that it uses mechanical energy. the thing that confuses me is that "power density". like if i take a...

but how does 98 watts are generated? from the friction generated by the pressure or just from the mere contact and separation of the layers?. what kind of energy does thos generators transform to electrical energy?. sorry for all my question but something here just really puzzles me

in the wiki article about nanogenerators there is an explenation(drawings) about "Vertical contact-separation mode of triboelectric nanogenerator" https://en.wikipedia.org/wiki/Nanogenerator#Triboelectric_nanogenerator and it doesn't look like there is much of a friction here. anyway what is...

other forms of energy conversions makes sense to me but what kind of energy triboelectricity actualy converts?, you can press piezoelectricity enough and produce electric current or move a dynamo and produce electric current but with triboelectric generator from what i understood all the current...

recently i began reading about triboelectric effect and triboelectric generators(and/or triboelectric nanogenerators) but i really need somebody to explain me this. those generators produce the amount of energy mentioned in this pic just from the contact and separation of the layers?. like if...
