A company called Solyndra pioneered the solar tube but this new invention by UK-based Naked Energy may just take cylindrical solar to a whole new level. Called Virtu, the product includes an integrated photovoltaic cell in a vacuum tube to generate both electricity and warm water at the same time. The setup keeps the PV cool to optimize energy production and maximizes space with a combined PVT solution.
This is a net-zero energy showhouse in the Belgravia neighborhood of Edmonton. The home, built by Effect Home Builders, has been open on Sundays and displays the solar-powered approach to reducing the use of fossil fuels. A massive rooftop solar array feeds energy into the grid and produces as much energy as will be needed on an annual basis. In addition, the home has several other green aspects.
