An airy-fairy idea. It won't "take off" for a long, long time, if ever.
Reasons:
1. Power lines and trees - major hazards.
2. Popularity leading to cluttered skies.
3. Noise.
4. Safety of those in the sky and those on the ground.
5. People on the ground with air rifles, lasers, AK47's (USA), and potato guns using them as target practice.
6. Privacy issues like what we have with drones in cities.
7. Energy consumption & cost.
8. Severe weather mitigation.
9. Lack of take-off/landing areas.
10. Regulations and licensing hassles.
Let's not forget taxes. As electric cars are being purchased by a small minority, the Victorian government has announced imposing a 2.5 cents per kilometre tax on them to prevent "losing" revenue from petrol taxes. With such an aircraft, don't even think for a minute the taxman won't have his hand in it.
