The drive towards green computing continues with the launch of a new PC from services firm Adept IT.

The Kentish company has introduced what it claims is the world's first carbon-neutral PC. SoftXpand has been designed for small businesses and other organisations to run eight workstations off one PC. Adept IT claimed that with the energy savings from the machine, companies could see a return on investment within two years.

According to an Adept IT spokeswoman, the appliance has been planned from the outset to be energy efficient. "The SoftXPand appliances have been designed to reduce the environmental impacts during manufacture, use, and at end of life. Each PC comes with five years of GVA certified carbon offsetting with Carbon Life to neutralise the energy consumption during use." She said that SoftXPand appliances used 16 percent of the energy a standard workstation may use.

Last month, Canadian company Userful launched an open source software product that allowed 11 workstations to be run off one PC. The Adept IT spokeswoman said that the SoftXPand option would be attractive for those companies who wanted to run a physical device.
