Plan to Tap T-ap the Earths Earth's Interior And Get Heat for Our Houses H oases HE temperature of the earth from T THE JL 50 GO to 75 feet down being always about the same summer and winter it has occurred to an Englishman named l to utilize this as a source of warmth In winter and coolness coolness coolness cool cool- ness In summer The temperature at those depths being heing between 45 and andO 50 O degrees 1 F. F It would not be possible to get from this source enough heat to make a room really warm but there were weeks last winter when a stead steady Indoors temperature of about 50 O de degrees rees without fires Cires would have brought happiness to millions and saved huge plumbers' plumbers bills And there will be days das in the next f few w months when it would be bo delightful to have ha air at a temperature of 50 60 degrees degrees degrees de de- de- de grees pouring from radiators into oura our a apartments e a is Tho British British Patent Office thought enough nough of Mr Idea to grant granth h him hm m a patent upon It His plan is put Into effect in three ways which are arc only varieties of at one This Is In the sinking of a well to the required depth and placing placing- therein a tube closed at Its lower end In this tube Is placed a smaller tube open at both ends The upper end of ot tho the larger tubo tube opens in the room room to be warmed the cold air descends through the smaller tube Is warmed In the depths and rises through the larger larger tube The circulation Is automatic according to the Inventor but may be f fig 2 d t Fig 9 91 up 1 i I Apparatus for lor br bringing subterranean temperature to the tho surface ace Fig l 1 I.
