> Very interesting. Just how much NEA material is there?
I couldn't give you hard and fast numbers, but I know that the number of NEAs discovered has gone up significantly since Gerard O'Neill published his plans.

Not sure if Hop David's website would have info on this, but anyway here's the URL:

Another website which discusses use of NEA materials is here:
