The Lightning GT has a technological advantage over the Roadster, or so it seems, depending on whether recharge time is an issue for owners. The company says the car takes 10 minutes to recharge, if charged from a three-phase power supply (those found in industrial buildings, compared to the residential single phase). The Tesla Roadster has an estimated 3.5-hour charge time from a residential outlet.This approach to charging electric batteries might solve a critical problem for the industry. A 10-minute wait is not that much different from the time people usually spend today filling up their cars.
I use this blog to gather information and thoughts about invention and innovation, the subjects I've been teaching at Stanford University Continuing Studies Program since 2005. The current course is Principles of Invention and Innovation (Summer '17). Our book "Scalable Innovation" is now available on Amazon http://www.amazon.com/Scalable-Innovation-Inventors-Entrepreneurs-Professionals/dp/1466590971/

cnet reports that The Lightning GT, a new electric car, boasts not only four seconds 0 to 60mph acceleration, but also a super-fast charging time:

The interesting thing to make note of is how the 10-minute charge in being marketed. First, its a 10-minute charge using a three-phase power supply (found in industries), which would need infrastructure to support it. Second, its a 10 minute charge for 90 miles only, if I am not mistaken. I would be interested to see how long does this car need to recharge with the help of the residential single phase power supply.
