This invention relates to hydrogen production using combined heat pumps and a thermochemical cycle. Low grade waste heat can be upgraded to higher temperatures via salt/ammonia and/or MgO/vapor chemical heat pumps, which release heat at successively higher temperatures through exothermic reactions, or vapor compression heat pumps that upgrade thermal energy with phase change fluids. Using this new approach, low grade heat or waste heat from nuclear or other industrial sources can be transformed to a useful energy supply for thermochemical hydrogen production.

Upgrading waste heat with heat pumps for thermochemical hydrogen production

A portable rest device for a laptop computer is made of a thermally-conductive material, and comprises a top face for receiving the laptop computer and a bottom heat-dissipating three-dimensional pattern. Due to this design, the portable rest device dissipates 1) the heat generated by the laptop computer and captured by the top face, and 2) the heat generated by the user when the bottom heat-dissipating three-dimensional pattern is disposed on the user's lap.
