More thoughts on Drones / Flying Cars

with 2 comments

Yesterday I posted about an NPR article about flying cars, and my opinion that the best way to make these a reality is to have them become laser powered.  It is interesting that this week’s Economist also has an article about flying cars.  If you thought this idea was far fetched, NASA has done some experiments of a proof of concept.  But getting power to a drone/flying car alone is not enough, because there is still a need to have enough energy stored in the drone/flying car to stay aloft for s sufficient period of time if the incoming power stops working.

So, we also need a breakthrough in power storage, where more energy can be stored with less weight in a given space.  Battery technology is not the long term answer.  They weigh too much,  charge too slowly, and have too short of an effective lifespan.  This is why nanotube supercapacitors are what will be needed to have ubiquitous flying transportation become a reality.
