Not only that, but you need to accelerate at or near apogee in order to achieve orbit or your path will be ballistic and you're going to hit the ground again. That's a fact of physics that can't be changed. Something without an engine or fuel can't do that.
the package could definitely include a small booster engine to circleize its orbit, but that would add more complexity.
It also invalidates their "without a drop of fuel" claim.
