Heat lamp %26 mantle with cooling fan Free 3D model

This 3D model was originally created with Sketchup 13 and then converted to all other 3D formats. Native format is .skp 3dsmax scene is 3ds Max 2016 version, rendered with Vray 3.00 This is to take the bite out of winter with some modest frost-proofing to add as required, this needs validating - I'm proposing a shade that uses greaseproof/baking rather than rice paper lined in the upper hemisphere with reflective foil, a 50w terrarium bulb, a pc cooling fan to pull heat down and simply a piece of wood fixed corner edge on to the base - dispersing heat [more] laterally (could also be foil wrapped); All sat just off the floor [heat rises] - maybe good for 1.5 - 2m² - with a view to being able to run up to four of these from a couple of lorry batteries..., any pointers/advice/feedback welcomed...
