ELECTRICAL EXHIBITS AT WEMBLEY.

DOMESTIC LABOUR-SAVING DEVICES. The Electrical and Allied Engineering Section of the British Empire Exhibition, which occupies a floor space of about acres in the Palace of Engineering, has been organised by the British Electrical and Allied Manufacturers' Association, and presents a striking demonstration of the way in which electricity has come into use in every phase of our social and domestic life.

On the north side of the section there will be a completely equipped boiler house power station of C,OOO-h.p,, together with a sub-station. The power station is small according to present-day ideas, but everything has been done to make it illustrative of the operations carried on oil a much greater scale in the large super-power stations now being erected ill various parts of the country. In the boiler house every appliance available for Saving labour will bo shown. The 'c<ial, which i 3 brought to the station in trucks, is handled mechanically, and conveyed to a large blinker in the roof of the building. From there it passes to the boilers, which are stoked mechanically, and measuring appliances are installed by which the attendant can . see the amount of coal which is being used, tile temperatures at various parts ol the boiler, and the amouut of steam which is being supplied to the power station. Ho can thus tell at a glance all that is happening in the boiler house. In the power station by the side of the boiler house are installed three steam turbines with direct coupled generators, and below . this aro fixed the condensers by which the steam, after being used in the turbine, is condensed find conveyed to the boner to be used again. Along one side of the power station is iixed a switchboard, through which the electrical energy is supplied to the various parts of the exhibition, every circuit being under perfect control. Arrangements have been made by which the public will be able to see all the essential details of the plant. The electric energy supplied from the switchboard is not of the right volta£© for most purposes of the exhibition, and sub-stations and transformer stations are installed in various parts of the exhibition grounds. One of the most interesting of these sub-stations, near the power station itself, is arranged for ' converting alternating current as supplied by the to direct current, largely for the of the amusement park. In the Palace of Engineering lt.xnt are examples of slow-speed delivering power to the switchboard a well as oil engines and gas engines. West the larger applications of eleclri" power those of special, interest to the public will be the electric app lances for driving of trauis aid tram: wavs and those for use m factories, all^these aro well represented. There will be exhibits of railway motors and control gear and ol th * coaches electrically equipped, and the public will thus be able to see the deLils of equipments such as those used in the London Underground Railw ay | and other places. . ■ As to the applications of power m factories, numerous examples oi electricity applied to special purposes w. bo found, not only m this section, but also in the Mechanical and Shipbuilding Section on the south side of the Palace of Engineering, organised hj the British Engineers' -Association. Electricity makes its appeal, however to the greater number ol people through the help it gives in our everyi dav domestic life, and a special part | of/this section has been taken by the I Electrical Development Association, mpresentin" the municipalities and* ccn»panies supplying electricity, to demonstrate what electricity-can do to simplify and lighten the labour of domestic ! work. , , . . . This particular section, which is in the north-west comer of tho Palace of Engineering, near the entrance to the buiTding, will show the best and most economical ways in which electricity can be applied to lighting aQ d heating for domestic purposes, alid there "u ill bo examples of electric, cooking and cleaning which will interest ever} householder. The exhibits in this section will comprise individual items which will enable the (visitor to see the wide choice of designs available for each of these purposes. The. section will be laid out from the point of view of comfort, and will be an undoubted attraction to women visitors.

There is still another department in the Electrical Engineering Section, which represents the latest achievement, not only in the practical application of electrical science, but also in securing enjoyment in the home —i.e., tho demonstrations of broadcasting and exhibits of wireless appliances. All the leading makers of wireless appliances and "listening-in" sets are exhibiting, and facilities will be afforded throughout the hall for visitors to inspect the very latest products of the manufacturing firms to demonstrations of what those sets

are capable. With the rapid development in the technical side of wireless and the improvements in the quality of reproduction, these exhibits shorild provide a source of unfailing interest throughout the whole period of the Exhibition.
