so each time we hit on the keyboard, there will be some kinetic energy
involved, is there any opportunities in collect and recycle them into maybe
battery or other uses?
maybe a good ppt project?

wonder how much energy is needed for the wifi/bt signal for wireless
keyboards.
maybe a chance for the keyboard to self-sustain?
hahaha....

I guess you'd ask yourself why a keyboard needs to generate energy. What's
wrong with absorbing energy from a battery or cable?

it does not "need" to.
but the energy are "wasted".
i do not know the technical details, but i heard prius is collecting the
energy during braking, then store that into battery.
this is what i thought, any opportunities to collect and re-use this "wasted
" energy for key board hitting?

How do you define wasted though. Keyboard is exposed to light, temperature,
altitude, magnetic field, all can be converted to some energy, why not ask a
keyboard to collect these "wasted" energy?

每个键分配一个频率，然后每次击键产生一个该频率的信号，
电脑直接pickup。这样可以避免发电和存储电能。
比如钢琴击键就完全可以直接通过电脑麦克风pickup，中间不需要经过
任何电路转换。可以在弦旁边弄个小的电磁转换装置，跟电吉他类似
那种，或许就可以做到不怎么发出声音但是转换成电磁波发射出去。
