The short answer is no.

Your first link is to a device that gets cold on one side and hot on the other when you pass an electric current through it. It will make some electricity when you heat one side *_AND_* cool the other.
Where do you see that you get 1 volt when you do that? Also, how much current?

Your second link is to a device that requires 3 volts input to produce 5 volts output. 1 volt will not do it.

After you fix all that, it will take hours to charge your n900 a few percent.

You will have better luck using a golf cart motor to push a full cement truck.
