Providing clean and free energy for the world is a key foundation for a heaven on earth and actually very simple to do.

It is all explained In "The Present" Read it for free at Truthcontest(¤)com. (See page 53)

He uses the term 'power' alot in this video, when he should be referring to energy. . .

Isn't nuclear power also solar power, just from a different sun than our own? I mean uranium was created through nuclear fusion in stars.

[Conor Tiffin]

Power is an energy per unit of time. As a rate of change of work done or the energy of a subsystem

[Jacob Hagel]

No, it's the day off for Christmas.

Nuclear and Solar power will make a great team in the future.

If solar panels were cheaper I'd buy some right now!

It is true that without gravity there would be no flow and you could argue that. However it is besides the point. To clear things up geothermal energy is thermal (heat) energy originating from the ground, hence it's name geo-thermal. The majority of this heat arises from radioactive decay in the Earth's core. Radioactive decay of elements born in long gone supernovae which had nothing to do with our sun and "solar". Simply look at the wiki page on geothermal for more info :)

I know this was 5 months ago, but you could argue that gravitational pressure causes the flow of geothermal energy due to the temperature gradient between the core and the crust.

With the advances in capacitors, specifically carbon based super-capacitors (not sure if i got the name right, but i'm close enough for google to point you in the right direction) storing energy would be more efficient, less wasteful, with less pollutants. And you can store more power in relation to mass of the capacitor as opposed to batteries. we are remarkably close to having all the pieces to use solar power as a primary energy source. And by close i mean a few decades at least.
