Here’s another idea for disconnecting from the mains electricity grid – not cheap to buy, but cheap to run on a pint of diesel per hour. It’s the WhisperGen off-grid heat and DC power generator sold by Volpower NZ Ltd, Auckland, distributor of Volvo Penta marine and industrial engines. The company shot to notice last year when, after a five-year product trial, it won a $300 million contract to supply British electricity and gas giant Powergen with 80,000 domestic AC units over the next four years. These will be installed in British homes as replacements for conventional hot-water boilers, running on natural gas to generate AC power and hot water. But natural gas is running out and rising in price.
