Starting to bust water into its basic elements

The basic electrolyser design is finally finished. After a lot of steel cutting and drilling, I've finally finished the first prototype of the machine which will tell wether or not pulsed electrolysis of the water, through special frequency and pulse duration control, can by itself be the key to making the process several times more efficient than conventional DC electrolysis.

For now there are a few issues to resolve, namely:

• Make the seal on the top cover air tight - even though the container was bought under the premise that it would be air tight, in practice is was verified that it was not;


• Control circuit FET transistor is heating up too much under a 4 Amps load - must check if the gate voltage is being enough to cause it to switch from cutoff to saturation and not somewhere in between. According to the device datasheet, it dissipates up to 150 Watts of power. In this case it has to dissipate around 40-50 Watts of power (10 to 12 Volts at 4 Amps), which is probably too much for the 25 cm^2 heat sink installed.

This is the complete setup (electrolyser + control unit + DC power supply):

Water - alternate fuel source and a panacea for mankind?

When it comes the time to pay after filling up the tank, you dearly wish your car could run on anything cheaper than stinky old gasoline (or diesel). Wouldn't an entire global economy depend on this precious product, and you could establish a parallel with other things like drugs, where the desperate sense of necessity leads to the unavoidable obligation of paying a large sum of money just to obtain a given ammount of it.

I start this blog with a great, not so new idea that I decided to reimplement and see working with my own eyes. The principles behind it are not new at all and go back to the early days of RADAR technology (1930's), in a time where microwave radio research was taking place to improve the accuracy of this type of equipment. The need for guiding radio waves through a low loss medium and to be able to selectively pickup signals coming from a particular direction (in this case echoes from the emitted pulses) led to the design of different types of microwave antennas. These antennas had to be both compact (in order to fit into small airplane compartments) and efficient (output most of the signal from the transmitter in a particular direction and receive with exceptional gain the signal returning from that same direction).
