iPlod, there's already a booming business launching satellites. Energy-wise, almost all the cost is from the first part, getting to LEO. If you can make that part cheaper (and hopefully more reliable than e.g. the recent SeaLaunch), it's fairly simple to include a booster to get your satellite (or evil death-ray platform) to the higher altitude you want.
PS - I agree with you on the overpriced microgravity Ferris Wheel, except that for all that money, we didn't even get a Ferris Wheel, just a one-armed, multi-winged purple people holder!
PPS - You should check out Bigelow Aerospace (?) -- it's wackos//////eccentrics//////////visionaries like that who will probably end up actually achieving real things. Imagine making $100s of millions from a hotel company, then using the money to pursue a dream of giant inflatable rooms in space!
