Patent number: 11639831Abstract: Cooling a first device and second device in a fashion to produce water. The method includes collecting environmental air from an environment. The environmental air is used to cool a first device. Cooling the first device generates first device exhaust air produced from the environmental air. The first device exhaust air is provided to a first device portion of a heat exchanger. At a second device portion of the heat exchanger, thermally coupled to the first device portion of the heat exchanger, second device exhaust air generated by cooling a second device is received. At the heat exchanger, the first device exhaust air is used to cool the second device exhaust air to a dew point, causing condensed water to be created from the second device exhaust air. The condensed water is collected.Type: GrantFiled: April 30, 2019Date of Patent: May 2, 2023Assignee: Microsoft Technology Licensing, LLCInventors: Christian L. Belady, David Thomas Gauthier, Sean M.

Patent number: 11011768Abstract: A fuel cell power controller tracks load current and fuel cell output voltage, and alerts on excessive fuel cell ramp rate, so another power source can supplement the fuel cell and/or the load can be reduced. A power engineering process makes efficient use of available fuel cell power by ramping up power flow rapidly when power is available, while respecting the ramp rate and other power limitations of the fuel cell and safety limitations of the load. Power flow decreases after an alert indicating an electrical output limitation of the fuel cell. Permitted power flow increases in response to a power demand increase (actual or requested) from the load in the absence of the alert. Power flow may increase or decrease in a fixed amount, a proportional amount, or per a sequence. A power controller relay may trip open on a low fuel cell output voltage or high load current.Type: GrantFiled: December 19, 2018Date of Patent: May 18, 2021Assignee: Microsoft Technology Licensing, LLCInventors: Di Wang, Sriram Govindan, John J.

Patent number: 10296073Abstract: Computing devices receive power from multiple fuel cells, consuming natural gas and outputting electrical energy natively consumable by the computing devices. The fuel cells are sized to provide power to a set of computing devices, such as a rack thereof. The computing devices of a failed fuel cell can receive power from adjacent fuel cells. Additionally, the fuel cells and computing devices are positioned to realize thermal symbiotic efficiencies. Controllers instruct the computing devices to deactivate or throttle down power consuming functions during instances where the power consumption demand is increasing faster than the power being sourced by fuel cells, and instruct the computing devices to activate or throttle up power consuming functions during instances where the power consumption demand is decreasing faster than the power being sourced by the fuel cells. Supplemental power sources, supplementing the fuel cells' inability to quickly change power output, are not required.Type: GrantFiled: January 9, 2017Date of Patent: May 21, 2019Assignee: Microsoft Technology Licensing, LLCInventors: Gregory Joseph McKnight, Shaun L.

Patent number: 10103574Abstract: Technology for concurrently powering equipment from multiple power sources, and the control thereof is disclosed. One example implementation of the technology includes a first power supply that powers equipment from a first power source and a second power supply that also powers the equipment from a second power source while the equipment is being powered by the first power supply. A target direct current (DC) output voltage of at least one of the power supplies is changed, thereby changing a ratio of the power being drawn from the first power supply to the power being drawn from the second power supply.Type: GrantFiled: June 21, 2014Date of Patent: October 16, 2018Assignee: Microsoft Technology Licensing, LLCInventors: John J.

Patent number: 10033210Abstract: A power supply is described herein which provides power to a load, such as a load including one or more computing devices. The power supply uses a slow-response power source (such as a fuel-driven mechanism) to handle a slow-moving component of the demand level presented by the load, and uses a fast-response power source (such as a battery or a capacitor, etc.) to handle a fast-moving component of the demand level. By virtue of this approach, the power supply can manage the load level as it appears to the slow-response power source, allowing, in turn, the slow-response power source to service even fast-changing loads—a task which it could not otherwise perform due to its native limitations.Type: GrantFiled: January 30, 2014Date of Patent: July 24, 2018Assignee: Micrsoft Technology Licensing, LLCInventors: Eric C.

Patent number: 9608284Abstract: A “Cascading Startup Controller” provides various techniques for quickly and efficiently initializing grids of interconnected fuel cells. In general, the Cascading Startup Controller dynamically controls heat exchange between fuel cells in the grid to produce a cascading startup of the fuel cell grid via an expanding pattern of excess thermal energy routing from hotter fuel cell stacks to cooler fuel cell stacks. This expanding pattern of excess thermal energy routing is dynamically controlled via automated valves of a heat exchange grid coupled to the fuel cell grid to decrease a total startup time for fuel cell stacks in the grid. Additional excess heat beyond that used to heat fuel cells to operational temperatures is then made available for a variety of purposes, including, but not limited to, preheating gas or other fuel for use by the fuel cells, local or community-based heating systems, heat-based energy cogeneration systems, etc.Type: GrantFiled: July 30, 2014Date of Patent: March 28, 2017Assignee: Microsoft Technology Licensing, LLCInventors: Eric C.
