The drawings below are diagramtic only ,the size of parts ,the pully wheels the expansion elements and element racks would need to be calculated. contact: kentsoft189@yahoo.co.uk
Operates day and night does not need direct sunlight to work
This relates to using the thermal expansion and contraction of a solid material, liquid or gas to turn a generator (3) producing electricity via a high ratio gearing system as shown in Fig 3 below, and expansion/contraction element(s) (4) shown in Figs 1 and Fig 2 below
The machine is designed to complete a day/night continuous cycle , although it may not be possible to complete the full 12 hour cycles the machine will still produce an amount of electricity and still run continuously unatended.
Figure 1 below shows an expansion contraction element (4) comprised of a solid material possibly a length of pvc plastic tube or box section (pvc has a high thermal expansion rate). Figure 2 below shows a jointed spring return element (4) possiply filled with alchohol, mercury or nitrogen that also have a high thermal expansion rate, the drive elements (4) would normally be placed externally and be open to the atmosphere.I have found a metre length of pvc pipe or sqaure section can expand to approx 2.3mm and alcohol filled spring return metal tube can expand to approx 2.4mm depending on tempratures, therefore say a 10 metre long expansion/contraction elemnt could expand by about 23mm and could be located on a roof or a in garden say or virtually anywhere conveinient
Fig 3 below shows a diagramatic view of a high ratio gearing system driven by an expansion contraction element (4) and turning a generator (2) to produce electricity.The high ratio gearing system is comprised of double pulley wheels (1) connected by cables that are fixed to each of the opposing pulleys (mainly not connected by belts) and of course limiting the length of run of the the gearing system to the amount of cable available on the pulleys, of the two pulleys on each wheel one pulley is driven by the expansion push of an expansion/contraction element (4) via the drive arm (7) and the other by the contraction pull of the same expansion/contraction element (4) via the drive arm (7). therefore the machine resets itself to run continuosly. It would maybe more practical to have a higher ratio between the wheels (3) at the lower load end ,(the generator (2) end) of the gearing machine than at the higher load end (drive arm (7) end) with the use of belts to connect the pulleys at the lower load end rather than the large amount of cable that would be required at this end. The gearing system is driven by the drive lever arm (7), the wheel (11) that is connected to the drive arm (7) only makes a part revolution and not a full revolution. A sping adjustable break section (13) maybe necesary to avoid damage should the element(s) (4) expansion or contraction exceed the gearing systems ability to absorb any more movement. All parts of the drive lever arm are connected by four pin bearings (14)
Of course the generator would run mainly depending on the change of temprature between night and day but it may also be possible to get runs on intermediate changes in temperatureIn total a machine that runs continuously unaided to produce electricity via the temprature difference mainly between night and day
The wheels of the high ratio gearing system could be placed in a horizontal position rather than a vertical position if required
It maybe possible to create a compact expansion/contraction element rack taking up less room and easier to site ,possibly fitting on a vehicle. Fig 4 below shows an example of an element rack consisting of a stack of element holding trays (8) placed one above the other. Swivel bearings (9) passing the movement of each element (4) on to the next . With a fixing point (6) to stop movement of the first element on the top tray and connection point (5) to fix the last element on the bottom tray to the drive arm (7). There are connections (10) to to connect one tray to another and connection point (5) is also used to carry the combined total movement of a trays elements to the first element on the tray below or above depending on wether an expansion or contraction movement is occuring.The connection point (5) could aso be used to connect the last element to the drive lever arm (7) of the high ratio gearing system.It would be neccesary for the racks structure to be sturdy and the bearings to be high precision to avoid any element movement loss
But of course the higher the gearing ratio the shorter (or lesser the number of) the expansion/contraction elements can be
Long expansion/contraction elements could be placed on rooves with maybe more than one high ratio gearing pair with generator with each element (4), with the gearing system and generator placed internally in a loftspace possibly or alternatly it maybe possible to link all the elements together to drive a single generator
It should be possible to make a complete machine at low expense with a very long lifespan
Of course many different configurations of elements and ratio gearing are possible depending on individual circunstances
It seems with the creation of renewable energy every little helps
