The place to start is Mt. Kilimanjaro in Africa.
Almost 20,000 feet tall, located a mere 3
o south of the equator, it's summit is above ~1/2 the atmosphere, it is the ideal geographical location to build an electromagnetic rail gun.
Until we get serious about lowering the cost per kilogram of payload space is going to stay out of reach, and to my limited understanding the least expensive, short term solution that we have the technology to construct now with no new breakthroughs needed in materials science or propulsion systems or power systems is to build a rail gun to launch non-human payloads into space.
I think Borneo also has some high altitude elevations near the equator, and of course Ecuador as well.
The wonders we humans could accomplish if we didn't waste our time and wealth on wars is beyond most folks imagination, and the fact that we are wasting our time and wealth on wars is of course tremendously evil in and of itself.

Of course those religious folks who are of a distinctive eschatological flavor (i.e. those who believe in some sort of preordained apocalyptic religious end to human history) mostly disagree that ending wars and using those resources for peaceful purposes is a good thing, but they're being exposed by politicians like Ron Paul
