An improved system for generating energy by exploiting wind at a height. The system comprising at least one generator placed on the ground and operatively connected to at least one device for capturing energy through at least one constraining element. The constraining element is designed to transfer mechanical energy generated, as traction force, from the device for capturing energy to the generator. Where the device is a non-constrained rotor, namely a rotor not connected to the constraining element, and is designed to convert wind energy at a height with the traction force having an intermediate direction between wind axis and a vertical line with respect to the ground.

Described is a device for measuring wind conditions during power kite activities. The device comprises an electronic processing unit, an anemometer, and a means of attachment to a power kite. The data from the anemometer is processed by the processing unit and stored locally or transmitted wirelessly to a secondary device (e.g. a smart phone or smart watch). The anemometer directly measures the apparent wind at the kite. In certain embodiments inclusion of an inertial measurement unit and a GPS unit provides a means of calculating the true wind by accounting for induced wind from kite and kiter motion respectively.

The present disclosure relates to and envisages a jetstream power generating system. Producing electric power from jetstream force presents specific, daunting, physics-based challenges, because jetstream forces are 30 to 50 times stronger than wind on the ground. The system is configured to harness the energy of these jetstream forces in farms as power generating infrastructure. The system comprises an airborne element configured to be subjected to lift forces while flying in a jetstream, a capstan drum, a tether coupled between the airborne element and the capstan drum, an arcuate guide track, a kite tracker displaceably mounted on the guide track, a conversion unit coupled to the capstan drum, a plurality of accumulators configured to fluidly communicate with the conversion unit, and a generator. The kite tracker is configured to securely guide the tether to rotate the capstan drum in a first direction with a force equivalent to the lift force to facilitate payout of said tether, and to rotate said capstan drum in a second direction when said tether is reeled in. The conversion unit is configured to be driven by the capstan drum, when the capstan drum is rotated in the first direction, to pressurize hydraulic fluid passing there through. Each accumulator is configured to receive, store and release the pressurized hydraulic fluid therein. The generator is configured to receive the pressurized hydraulic fluid to facilitate generation of electric power.
