Fig

FIG. 3 is a section along the line III- III of FIG. 2.

The cell as shown in FIG. I comprises a gas-tight casing 11 which is formed from a non-corrodible material such as a plastics material as is known in the art. A plurality of cathodes 11 and a plurality of anodes 12 are supported within the cell by means of an electrically insulating central post 13, with the cathodes and anodes being spaced apart by means of insulating spacers 14. The anodes 12 are all connected in parallel to a positive terminal post 15 while the cathodes are all connected in parallel to the negative terminal post 16, these connections being indicated in dotted lines in the drawings. The cathodes and the anodes are preferably in the form of disc like plates of a suitable metal which is consistent with the composition of the electrolyte utilized so as to ensure a satisfactory life to the cell. The plates may be shaped to conform with the shape of the walls of the cell which may be circular in cross section as indicated or any other desired shape.

The central post 13 is preferably in the form of a tube which extends out of the cell as at

The lower end is of the tube is open so that air can be pumped into the cell through the central post 13 and enter the cell via the lower end 18 where it will pass up through the electrolyte.

This will keen the electrolyte constantly in motion and thereby assist in the rapid removal from the electrodes of any gases that might be adhering thereto.

In the modification shown in FIG. 2 and 3, the electrodes are each provided with holes 17 and in such a case the central post 13 is preferably formed with at least one air hole 19 adjacent the lower end 15 thereof. A deflector plate 20 is also supported by the central post 13, this plate being dish shaped so as to deflect air issuing our of at least one air hole 19 up through the holes 17 in the electrodes.

Such action further assists in dislodging any bubbles of gas clinging to the electrodes,

The cell also includes a gas outlet 21 so that the air which enters the cell together with the gases produced by the electrolysis can be exhausted out of the cell into a suitable storage tank (not shown in the drawings). If desired such storage tank can be arranged to accept the gases under pressure and for this purpose the air pumped into the cell will be pumped in under the required pressure. A gas drier (not shown in the drawings) can also be interposed between the gas outlet 21 and the storage tank.

Although the electrolysis will naturally produce considerable heat, nevertheless it can be found advantageous to install a heater in the cell, preferably in the bottom of the cell, to assist and facilitate the warming up of the electrolyte so that the cell reaches its most efficient operating conditions as quickly as possible.

Preferably also, current limiting means as is known in the art are employed so that the intensity of the electrolytic action can be controlled.

Means may also be provided for the automatic replenishment of water within the cell as the level of the electrolytic drops during use.

While it is recognized that the mixing of hydrogen and oxygen will create a dangerous explosive mixture, nevertheless by carrying out the invention as here in before described the risk of explosion is minimized.

The gases produced can be utilized for instance as fuel to power an internal combustion engine and for this purpose it is desirable, as before mentioned, to mix with the gases evolved during the electrolysis a proportion of air so that when the mixture is ignited within the cylinder or cylinders of the engine, the explosive force so created can be of the desired amount.

While in the foregoing description reference is made to the utilization of the mixed gases as a fuel, it will of course be understood that the gases can be separated for individual use by techniques as known in the art.

What is claimed is:

1. A process for producing by electrolysis of an aqueous liquid a combustible mixture of hydrogen and oxygen, comprising: electrolyzing the aqueous liquid into hydrogen and oxygen in an electrolytic cell having a gas-tight casing, a substantially central tubular post mounted in the casing and having an air inlet at its upper end, and a plurality of electrodes supported on the post and axially spaced there a long. alternate electrodes being connected to a first electrical terminal and to a second electrical terminal respectively connected to a respective poles of a current source and being mutually insulated, the post having an air outlet below the electrodes out of which flows air from the air inlet into the cell and over the electrodes; and a source of air under pressure connected to the said air inlet forcing a flow of air through the aqueous liquid contained in the cell in operation thereof the cell having in its upper region a common outlet exhausting the combustible mixture comprising air forced through the cell and hydrogen produced by electrolysis of said liquid in said cell.

2. The process according to claim 1 wherein the electrodes are discs each having a plurality of holes there through.

3. The process according to claim 1 further including a dish-shaped air deflector plate supported on the said post below the said air outlet.

USING SOLAR heat radiation ENERGY

a cardboard and tin foil cooker

By using some cardboard and some cheap al foil it is possible to capture the suns energy and use it to do some useful work. All that is needed is some pva craft glue ,a square cardboard box (tv box) and some cooking foil..

What you need to do is to remove the top flaps from the box and then cut the box from one corner to another so that what remains is a cardboard box with two sides and the bottom intact.

You need to fix to the inner box sheet of al foil so that the complete inside sections are covered with foil as shown in illustrations. It may be easier to use ,if you flatten the cardboard so that you can place it on a flat surface.

To place the foil on the cardboard cover the entire inner surface with a mixture of 50 percent of water and pva glue throughly mixed together.

Place the foil on this surface ,

To do this neatly and so the foil adheres neatly, place one end on the cardboard and glue and pull into place rather than just placing all the foil on the cardboard at one and the trying to flatten it out.

A survival version

When you have done this leave to dry it usually takes a couple of days.

You need also to make an adjustable reflector, that will fit corner to corner at the bottom of the box it make seem that you don't need it , but there is a considerable amount of heat that is lost if it is not reflected back into cooking zone.

Some of these units I have seen will take about 1/2 hr to cook something in the middle of summer ,I doubt this would be practical in the middle of winter a good suuny day is what is really needed.

If you make a survival version as shown above you will be able to flatten the unit and take it camping with you.

It no different to box angle version except the bottom two flaps are not joined together and you will need to mak a extra square section to place on the bottom.

If you get lost in the great outdoors they will make excellent signal mirrors as well. Aim the box just slightly ahead of the suns path for best result. It seems to work better if the cooking vessel is also black in colour.

Although not necessary if the unit not left in bad weather ,I have covered the outside cardboard surface with foil to offer some protection from rain.

Perhaps some adhesive plastic used to cover books could be used for the outer covering instead.

Solar Panel Basics

Global warming is a huge problem which will significantly affect every country in the world. Many people all over the world are trying to do whatever they can to help combat the effects of global warming. One of the ways that people can fight global warming is to reduce their dependence on non-renewable energy sources like oil and petroleum based products.
