On June 20, 2017, two companies, Kitty Hawk and Uber, announced their plans to bring flying cars to reality very soon.
Sooner than you think, flying cars may appear in the skies. Imagine never having to worry about traffic, stoplights, or road construction. A flying car can get somewhere much faster than one traveling by road. On the other hand, imagine having to avoid planes and other flying cars. Also, what if your battery (电池) dies when you arc in the air? And, how will you know where to get down on the ground?
Kitty Hawk is a tech company supported by Google co-founder, Larry Page. Kitty Hawk president, Sebastian Thrun, helped start Google’s self-driving car project. Kitty Hawk expects its first flying cars will go on sale by the end of this year.
According to the Kitty Hawk website, the car is electric-powered and will be able to travel up to 40 kilometers an hour. As of now, the car can only be flown over fresh water. However, Kitty Hawk has not yet announced the price.
At a conference last week, Uber announced plans for flying taxis to begin carrying passengers. Unlike the Kitty Hawk company, Uber does not plan to build a flying car. Instead, it will use the resources of partner companies.
Uber says its flying taxis will use electric power and can travel up to 241 kilometers an hour. The company said that could cut the travel time between San Francisco and San Jose, California from 2 hours on the road to 15 minutes in the air. Riders can use the Uber app to book a flying taxi to take them to their destinations. The company has not yet said how costly air taxi travel would be compared to road taxi travel.

The transition from old fuels to new will be slow, as will the development of new technologies that present feasible alternatives to fossil fuels or help eliminate food and water problems. All current technologies are inadequate, and new ones will probably not be commercially possible by 2025
