Abstract: Techniques are described for implementing a cloud computer system to provide access to a custom execution environment for execution of custom executable instructions. Users may be able to configure one or more different types of template execution environments, e.g., a virtual machine environment, each of which can be used to establish a type of custom execution environment. Users may configure the template execution environment with regard to settings, states, resources, permissions, or other criterion related to an execution environment. Upon request, a custom execution environment (e.g., a child execution environment) may be established for running one instance of a custom executable instruction. The custom execution environment may be based on the template execution environment. The custom execution environment may provide a secure, isolated environment for execution of a custom executable instruction. Access permissions for the custom execution environment may be configurable depending on a type of execution environment desired.

Abstract: A method and apparatus for load balancing trapped solar energy using small masses of low-boiling-point fluids to absorb heat in an evaporator situated in higher heat reservoir near the ocean surface using the latent heat of evaporation to convert a portion of the heat to another form of energy in a turbine or other heat engine, providing a variety of energy related service applications to end users from the converted energy, depositing a residual latent heat of evaporation in a deep ocean heat exchanger situated in the lower heat reservoir, using the cold seawater as a heat sink. A latent heat of condensation warms the cold seawater making it buoyant. The warmed water rises slowly by convection to the higher heat reservoir where the heat is recycled in a turbine or other heat engine. The condensed liquid is pumped rapidly back to the ocean surface to complete the fluid cycle.
