timescale for Earth to reach type one status

i'll refer you to the following from wikipedia:
* Type I - A civilization that is able to harness all of the power available on a single planet, approximately 1016 W (given the Solar constant for Earth, this value for Earth exceeds 1.74×1017 W).
* Type II - A civilization that is able to harness all of the power available from a single star, approximately 1026 W (the Sun outputs approximately 3.86×1026 W).
* Type III - A civilization that is able to harness all of the power available from a single galaxy, approximately 1036 W.


so how long till we reach that status? As in also, what sort of discovery will be a landmark towards achieving that end? I would have thought geothermal use for electricity production? but maybe its AI so that machines can be more efficient?

A really great discussion that took place on this topic (with the same source even) can be found here: Types of Universal Civilizations; Type 0, I, II, III, IV, V ... God?

We're somewhere hovering around Type 0.95, I believe.

thanks a lot... i really should have googled it.. 3pages of info there!!! thanks again
