promising option uses carbon nanotubes, which not only can store far
more electricity by weight than lithium ion batteries but also retain

Also, I included this video for conceptualization purposes only.
The battery pack weighs 200lbs. In 10 years this will make a good
comedy film. It's like looking at a steam engine in a volkswagon.
(however it does fly) The new generation of technology will shrink
that battery pack down to 5lbs, and the size of a cigar box.
Once that occurs, you will see power beyond your imagination
that will outrun a Cessna Corvalis TT.
