i want to know what would be the best energy source for a project, when you dont want the energy source to be an issue with life of energy?

[Reply #1 on:]

Depends on how much energy you plan on using, how quickly, and for how long.

[Reply #2 on:]

enough energy to power tinkershield and waveshield and also LED lights for project and as long as i can go with a good clean energy source?

Come back when you've got a specification, not a wish list

Got a running stream nearby? I'd go with micro-hydro.

As AWOL said, come back when you have a spec. Also what do you mean by "clean"? Does that mean you won't be happy using batteries? You don't want to use a cheap Chinese power supply because of their pollution record? You don't want to use an expensive US power supply because of their pollution record? You want to energy harvest from the temperature differential in your lounge room? What?

You can always try a water paddle generator.
Do you live next to any streams?
