Engineering

Energy supply systems for remote applications such as: telecommunication systems, village energy supply, home industries, agriculture processing center, drinking water supply, and public health facilities utilizing locally available energy sources such as solar micro-hydro, wind, biomass, and combination of them (hybrid).

Technical systems utilizing renewable energy sources for communication sectors (i.e. photovoltaic, micro-hydro), such as: base transceiver station (BTS), repeater station, radio communication (e.g. sea navigation, railway crossing, radio beacon, and highway information system), cathodic protection, traffic signaling (e.g. light house, buoy, barrier flasher).

Decentralized power supply systems and rural electrification, such as: stand-alone photovoltaic, floating PV for coastal areas, micro-hydro power, biomass, wind energy converter, and hybrid power systems.

Mechanical and electrical for private houses, real estates, commercial buildings, and industries.

Lift, escalator, passenger conveyor, and other within-a-building transportation types.

Biomass gasification to replace the use of fossil-fueled energy.
