An efficient, accurate, and stable solution to the
electron transport problem is presented.
The two-stream approximation is discussed in detail,
but the solution is developed for the general multistream case.
Applied to the photoelectron problem, it is shown that
accurate escape fluxes are obtained using only 10
altitudes distributed over the region 100 - 1000 km.
The local equilibrium, two-stream, and multistream solutions
to the photoelectron problem are compared.
In addition, a recursion relation for the moments of the elastic
angular scattering phase function is presented.
