Metal silicates or phosphates are deposited on a heated substrate by the reaction of vapors of alkoxysilanols or alkylphosphates along with reactive metal amides, alkyls or alkoxides. For example, vapors of tris(tert-butoxy)silanol react with vapors of tetrakis(ethylmethylamido)hafnium to deposit hafnium silicate on surfaces heated to 300° C. The product film has a very uniform stoichiometry throughout the reactor. Similarly, vapors of diisopropylphosphate react with vapors of lithium bis(ethyldimethylsilyl)amide to deposit lithium phosphate films on substrates heated to 250° C. Supplying the vapors in alternating pulses produces these same compositions with a very uniform distribution of thickness and excellent step coverage.

A sub-surface tubing arrangement for use in a direct exchange (DX) geothermal heating / cooling system includes a primary sub-surface liquid refrigerant transport line, a primary sub-surface vapor refrigerant transport line, at least one sub-surface heat exchange refrigerant transport line functionally connecting the primary sub-surface liquid refrigerant transport line to the primary sub-surface vapor refrigerant transport line, and either vertical or horizontal supplemental sub-surface refrigerant line connected to one of the primary sub-surface liquid or vapor refrigerant transport lines.
