Introducing Power Spout – Micro Hydro Systems

power-spout-logo-web

Even a small stream can generate consistent, clean, dam free, renewable electricity at a price per Watt lower than solar or wind.A single PowerSpout at a site good enough to generate 1kW can produce enough electricity for a typical house for a year (>8,000 kWh/yr).The small (18 inches wide),all-weatherPowerSpout PLT is one of the most reliable, cost-effective generators around because we have spent a decade making micro-hydro efficient and affordable.
