Doctor Barnett's Amazing Audio Solar Cyclonator



A 12 volt PA system powered by a tandem bike dynamo. This provides Safe Free Energy anywhere.

Designed and bult by Doc Barnett - Crewed by The Doc himself, Stu:Art, Goatoid and Dr M.

Total success has been achieved at many venues around the UK.

The references listed below give some examples of bike power systems.

The block diagram of the mechanics for the Cyclonator tandem is shown below. The alternator is shown bottom centre, marked A on the drawing, with an idler wheel, marked I, shown level with it but the other side of the rear wheel. 8mm polyurethane belting (Redthane belt from Wyco in Slough, an equivalent belt being also available from Bondaband) is used as drivebelt for both alternator and idler. The belt is heat welded to the required length, 2950mm in our case. Losses due to belt slipping are reduced by the high wrap factor by including the idler wheel. Note that lead sheeting added to the rear wheel as flywheel isn't shown on the drawing. The extra inertia due to this flywheel action makes starting the bike a lot easier.

I have CAD design files for the elaborate power control circuitry which efficiently controls the power being pedalled into the battery, but for simplicity I'd recommend anybody first trying this thing out to follow Nick Mercer's instruction sheets (see reference 2) for the initial electronic design. Only once the system is proved to be going would I suggest adapting it to include my control circuit.


It shouldn't be too difficult then to dismantle the alternator to remove its voltage regulator and provide access points with additional cables to the slip rings which supply controlled power to the field coil.

The advantage of my design is that my controller is primarily a switch mode power regulator in which the voltage trip level of 14.4V is used as an additional protection against overcharging, whereas as used in a car, the regulator has only the voltage regulation function and will load the engine (your legs) with several hundred Watts if it wants to, as it does when the battery voltage is anywhere below maximum. The range of output power when using my controller is 30 - 110 Watts output power. Although it's possible for one cyclist to generate this full power for short bursts, it's better to spread the load over two people powering one generator, hence the tandem design.
