Abstract: An attachable and extendable saw and methods for cutting an object on a work surface with the attachable and extendable saw are provided. The extendable saw can include a saw blade housing coupled to a main body by at least one extendable member, the saw blade housing at least partially covers a saw blade and the extendable member can be configured to move the saw blade housing and the saw blade between a retracted position and an extended position relative to the main body. The extendable saw can also include a motorized unit coupled to the saw blade and configured to rotate or provide other blade movement to the saw blade and a switchable device or unit disposed on the main body and having at least one contact surface that facilitates attachment of the extendable saw to the work surface, said contact surface being switchable between a magnetized or vacuum state and a non-magnetized state or non-vacuum state, respectively. Attachment of the saw blade to the attachable and extendable saw is provided for.

Abstract: Methods for forming a geothermal well are provided. A method for forming a geothermal well can include drilling a first wellbore having a substantially linear segment connected to an arcuate segment. A second wellbore can be drilled to connect to a terminating end of the arcuate segment, thereby forming a wellbore loop. A thermally conductive tube can be disposed through the wellbore loop.
