In order to have a self-contained power unit for a
lifter we need a lightweight means of creating high
voltage in the tens of kilovolts range.
To quantify it, a lifter can be made at a thrust to
power ratio of about 1 gm lifted to 1 watt power
Here's a lithium battery to put out 30V DC:
Amp Hours: 4000 mAh
Rating: 10-12C continuous, 20C (80A) burst
Output: 29.6V Nominal, 4000mAh
Dimension: 50mm x 245mm x 28mm
Weight: 656 grams
There are lightweight converters to convert the DC to
AC for a tesla coil:
DC to AC Inverter with the 555.
However to power the lifter we need say 30,000V. A
problem with transformers is that their ferrite cores
make them too heavy for the lifter to raise.
So my question could you make the transformers to
power a tesla coil be air cored?
Then another question is could you make the toroid on
the tesla coil be lightweight?
