An Ethernet Host Adapter is a host adapter for Ethernet networking and is also called by a variety of other names such as: Ethernet Adapter, Network Adapter, LAN adapter, Ethernet Card, Network Card, Network Interface Card (usually abbeviated NIC) and so on.
In addition to electricity, fuel cells produce water, heat and, depending on the fuel source, very small amounts of nitrogen dioxide and other emissions. The energy efficiency of a fuel cell is generally between 40â60%, or up to 85% efficient in cogeneration if waste heat is captured for use. The fuel cell market is growing, and in 2013 Pike Research estimated that the stationary fuel cell market will reach 50 GW by 2020.
Fuel cells operate without combustion, so they are virtually pollution free. Since the fuel is converted directly to electricity and heat, a fuel cellâs total system efficiency can be much higher than internal combustion engines, extracting more energy from the same amount of fuel.
