摘要： 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.

摘要： 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.

摘要： According to some embodiments, a power supply component for a computer server may include a physical input receptacle adapted to receive with of an Alternating Current (“AC”) plug and a Direct Current (“DC”) plug. An AC-to-DC rectifier circuit coupled to the physical input receptacle may convert AC current into DC current when AC current is received via the physical input receptacle. The power supply component may also include a DC-to-DC voltage regulator to reduce voltages swings. The power supply component might be associated with, for example, a computer data center.

摘要： 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.

摘要： 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.

摘要： A bus architecture for supplying power to loads in a datacenter includes a first DC bus including a first bus conductor and a first plurality of source/load groups. Each of the first plurality of source/load groups includes a first power source and a first plurality of loads, wherein at least one of the first plurality of loads includes a server rack. The first power source in each of the first plurality of source/load groups is sized to supply power to the first plurality of loads for the corresponding one of the first plurality of source/load groups. The first power source in each of the first plurality of source/load groups is also sized to provide excess capacity to be shared by the first plurality of loads corresponding to other ones of the first plurality of source/load groups.

摘要： A “data plant” accepts power-generation-capable raw materials and outputs processed data. The processed data can be delivered to consumers more efficiently than other forms of power transfer, including power transfer through electricity, steam, physical motion, and the like. Consequently, data plants can be located where power-generation-capable raw materials can be obtained inexpensively, for free, or where power-generation-capable raw materials are waste products for which the operator of the data plants can be compensated for processing. Self-powered data plants need not even be continuously fed with power-generation-capable raw materials and, if such data plants receive and output data via wireless communications, the self-powered data plants can require no physical connection or attachment at all. For example, a single piece of silicon comprising a silicon solar cell that generates electrical power and silicon circuitry that consumes it to perform data processing can be a silicon self-powered data plant.
