Lifter with HV power source

[starcruiser]

I built a lifter some years ago using a car coil, GM coil controller and a signal generator to drive the controller which is basically a darlington pair switcher (switches the ground line to the coil).

You could try a cheap flash circuit perhaps to generate enough tension to create lift.

BTW, the RC helicopters (I fly them) can consume high current when the disc is loaded. There are smaller ones, less than 12" in length which uses a single cell Lipo battery (3,7v) at 500maH and can do most of what a larger one can. Most of the motors are brushless with Neo magents for the field and PWM controllers for the drive, these can be 80+% efficient in operation.

For those looking to hafve a smaller power suppluy (battery) Lithium Polymer Batteries can source high current for short periods of time, the 500maH pack i mentioned above can source several amps at 3.7v. The larger packs come in various voltages, the most used are 12v, 24v and 48v configurations, the larger packs have a higher current sourcing ability up to several hundred amps.

a 24v 5000maH pack with a 35C discharge rating can source  5 x 35 = 185 amps for a short period of time without damaging the pack.

Yes, I know LiPo batteries are very powerfull and quite lightweight.

I believe that there is not big interest in building so light and so specific power supplies, there is nearly no reason to do it.
So I think there are lot of areas of possible improvements.

I am PCB engineer so I want to try some experiments with this.
Also I believe that we can create much better concept of the lifter.

By the way, why we should believe NASA? We should test it ourselves if it really does not work in vacuum at all.
That mean, we should make own decissions and get to own results.

By the way I am in a process of building/designing very light HV power source.
It could weight around 20g only with output power approximately 200W.

I will share all needed data and schematics if this goal is achieved sucessfully soon.

It seems ION propulsion is there for more than 40 years right now and is very efficient and already used by NASA and others for years.

For example Deep Space 1 was first module with Ion Thruster released in 1998. And as I understand it uses very same principle as Ion Wind in our Lifters.
Of course there are some modifications so it differs from ion wind lifter. For example Ion magnetic accelerator, very similar to this used in CRT displays.
Instead of air it uses an exotic gas, mostly it is Xenon.

It is known that it is cca 50x more efficient than Jet propulsion. Deep Space 1 achieved 4.2km/s speed, so for me and lot of scientists this propulsion is very worth and _IS_ designed for deep space flights too with such modifications.

From my lifter experiments I recall, that a lifter does not need straight DC, it could be pulses or even spikes. But the pulses or spikes have to go in one direction (AC will not work). So, one does not need smoothing capacitors but at least one high Voltage diode is necessary (to rectify the current coming from the secondary of the high Voltage transformer).

Polarity is important. Once you have built a lifter switch plus and minus around and test which way works best. Negative air ions are heavier than positive air ions, therefore you want to shoot off negative air ions.

The higher the Voltage the better, starts to work with 20 KV, I used 37 KV  from a colour monitor (very dangerous, be careful, wear gloves).
