One of the most common and regular warnings that we get on our cellphone is “Low battery!”. If unfortunately, the charger is not with us then we tend to borrow it from somebody or search for a charging point. If we are even more unfortunate then we have to stay paralytic till we get it going as the phone dies.
Think of a way by which you could charge your cellphone by using energy from something you primarily use your cellphone for. You talk!!! Look at this: Talk-powered cell phones? Nanoscale piezoelectrics could make it real http://www.networkworld.com/community/node/35879
from the post “A Taiwanese research institute on Friday revealed a folding display on a smartphone that allowed its screen to double in size to 5-inches.
The mock-up smartphone, developed to showcase the screen, is styled like other smartphones and opens like a book turned on its side so when open the display is on the top half and the bottom half is the keyboard.”
Here is a concept phone called the Glass Phone, by Yanko Design . I dont know if this will ever come to reality till we are alive, but this definitely proves that thoughts are centuries ahead of the facts. Watch this picture below… Isn’t this tempting!?
