Default Balloon Lifted Antenna

I may have posted this before, I don't remember.

I have taken a Helium Balloon and lacquer coated wire, perhaps 100 feet, and
used the balloon to lift the wire. A single balloon, the metallic (Mylar)
kind, was sufficient to lift the wire and its spool. My ability to lift the
wire was limited by two factors:

1. A high tension wire was present in the front of my house:
2. The wind.

PLEASE NOTE, the two items above conspire to make the experiment quite a
dangerous one, as the distance that the wire can be lifted is limited by the
distance to the high tension wire. (whether 110 volts or 3000 volts).

The wind, even moderate, tends to take the wire considerably off a vertical
orientation. Perhaps more balloons would have given the situation a more
significant lift.

IF one were to live in an area without any high tension (110 Volt or the much
greater primary voltages) and had a sufficiently windless day, thereby
succeeding in lifting 100 ft or more of wire, how efficient would this be for
the purposes of receiving shortwave?

In theory, on property of sufficient footage, one could go 100 feet or more
away from the house, use the balloon to lift the wire, tie the balloon off
(actually it could be guyed, limiting its range of motion) with an independent
string or such, then take the wire itself back to the receiving station at the
house. This would produce a slope with the upper end of the slope considerably
off the ground.

Would STATIC be a serious consideration for such an arrangement due to the
exposure to winds?

Just a thought, as I am again at a property with insufficient acreage to
conduct such an experiment.
