Electric oxymoron.

Chinese Ehang unveiled an electric drone able to carry a passenger at CES. Batteries are said to last for 23 minutes of manned flight and once the four propellers are folded, the drone takes up no more than a parking. The company is ready to launch its very private flying object this year for up to 300,000 dollars. Question is, if regulators will ever allow it to take off.
