  • Power from Wind: A History of Windmill Technology

    Sep 12, 1996The wind is a fickle source of power. Windspeeds are frequently too low to be of any practical use, so that windpower has generally remained a marginal resource. Since the inception of windpower around 1000 AD, technology has been deployed to obtain the most economical power from wind. The author traces its technical evolution, concentrating on the growth in understanding of wind

  • This Powerpod Compact Wind Turbine Is More Powerful And

    Nov 19, 2020Instagram. One 1kW Powerpod generates as much as three times more power than a pole-mounted turbine because the shell funnels the wind to an advanced blade system within the pod, which increases wind speed by 40%. This acceleration of wind speed generates electricity even when wind speeds are low, so more power is created, more often.
