Fuel cell technology for data centers isn't widely used yet, but for some companies in areas with high electricity costs or where there are mandates -- or tax incentives -- to find alternative energy systems, moving off the public grid and plugging into an unconventional power source may make financial sense.
Products like Bloom Energy Servers convert methane from natural gas or biogas, both of which are cleaner alternatives to coal and oil.
While larger companies like Apple have made significant investments in fuel cell technology to power their data centers, most traditional facility operators may be reluctant to let go of their generators and embrace this relatively new source of energy. It's only a matter of time before a hacker infiltrates your system and holds your files hostage.
Windows systems administrators can check out this guide to see what enhancements are coming in Microsoft Windows Server 2016. The release of Microsoft's latest server OS gives organizations a chance to rethink their IT infrastructure.

Leviton light switches, occupancy sensors, hotel card readers, and other energy-saving RF devices are powered by kinetic energy -- no batteries required. Leviton LevNet devices, using technology from Enocean, can save energy and hassles in MDUs including hotels and dorms. It’s easy enough to update a multi-dwelling unit (MDU) with energy-saving automation if the devices require no new wires. Even button-less LevNet products have ways of harnessing energy without the use of batteries.


Occupancy sensors, for example, are powered by the slightest changes in energy states, for example, the rise and fall of the temperature or ambient light. The magic is not just in the energy-harvesting technology but in the structure of the RF communications.
Two-way mesh-networking solutions such as Z-Wave (which Leviton supports in different lines) and ZigBee may be lightweight compared to WiFi, for example, but they require too much energy to operate without wires or batteries.
The same is true for standard security sensors which are always listening for activity on the network. On the other hand, LevNet switches and other devices are not constantly at the ready, waiting for instructions from a sensor or controller. When a user enters the room, he hits the light switch, generating the energy to power the radio transmitter. In addition to the occupancy sensors, wireless light sensors are available, powering themselves with built-in solar cells that draw on available ambient light. Other products in the LevNet line include thermostats, handheld controllers and the latest introduction: motorized shade controllers.
Hendler explains that the complete line is ideal for MDUs, including hotels and dorm rooms, where residents tend not to care about energy usage. Most notably, the European-style card holders in the LevNet line make perfect sense for these venues. Typical LevNet scenario: wireless, kinetic-powered hotel key card sets lights and temperature to comfortable settings when the room is occupied, and energy-saving levels when unoccupied. The Wireless Self-Powered Hotel Key Card Holder is designed to create energy saving solutions for the hospitality industry.

For example, turning the water heater, lighting, maintenance of indoor temperature according to schedule, irrigation management, stove, coffee maker, oven, remote opening of doors and all appliances with consumption up to 3000W. An individual Bloom Server produces 200 kW of energy and can be stacked to add more energy capacity to meet the particular data center's needs.


But in areas where the power grid is unreliable, a fuel cell installation may be one way to save some green while keeping the lights on. If you reside outside of the United States, you consent to having your personal data transferred to and processed in the United States. A new adapter turns Somfy RTS-enabled wireless controllers into LevNet (Enocean)-compatible devices.

After a set amount of non-activity, the sensor signals a LevNet-enabled wired RF light switch to turn off, and the cycle begins again.
Furthermore, swapping out batteries in potentially hundreds of living units would be untenable for the maintenance crew. Inserting a Key Card provides the energy to transmit an RF signal to LevNet RF Receivers that control lights or other devices in the room. Julie majored in Economics at the University of Michigan, spent a year abroad at Cambridge University, earned an MBA from the University of Texas at Austin, and has never taken a journalism class in her life. When entering a room, a Key Card is inserted into the switch and an RF signal is sent to the Receivers that control the loads in the room. The individual Receivers then communicate with their corresponding loads to close the circuit. WiCo represents smart Wi Fi plug that serves as a high distance remote control for electrical appliances up to 3 kW.
When the user exits the room and removes the Key Card from the switch, another RF signal is sent to the Receivers to open the circuits. Furthermore, it is provided with a temperature sensor and can act as an intelligent thermostat.
