Why can't we generate electricity from Earth's electric field?

This may be very silly, but I need to understand this to get my concepts right.

Consider the fact that the electric field b/w the Earth's surface and the ionosphere is on an average $100$ V/m, then if we were to keep the terminals of a bulb around $1$-$2$ m apart (vertically) in the atmosphere, will the bulb glow? Why, or why not?
