Habbear thank you, but that is actually implemented and ruled out due to poor connectivity in a lot of regions.
Something in Agriculture. A smart seed, with an inbuilt battery and container, which ejects seeds in the soil at the right time of the year. All the farmer has to do is take the harvest and the plants out. At the right time, the device automatically pops out a new seed, and you could add some features like be connected to the mobile or something.
Sounds like a good idea. Feel free to pm me more details if possible.
and Coinhoarder, I believe all that is already implemented.
Id recogition software that is wearable.
Like a fingertip or eyeglasses that can do a password for whatever site your going to so to access your email account, bank account etc.
I like this too. But I used to think that since phones and laptops store this information hence it is hackable,and is why banks don't use it.
So far, I like ajaxmor's idea. Will let this be open for a few more hours and decide. thank you all for the wonderful ideas so far.
