Harvesting solar power in space one step closer

From Tereza Pultarova for E&T Magazine:  Japanese engineering giant Mitsubishi has successfully demonstrated wireless power transmission over a larger distance paving the way for harvesting energy in outer space.
During the test at Mitsubishi Heavy Industries’ Kobe Shipyard & Machinery Works facility near Osaka, the engineers managed to beam 10kW of power through a microwave transmitter across a 500m distance.
 
As the beam of microwaves hit the receiver and got converted back into energy, its LED lights turned on using the received power.
 
Mitsubishi said the test ‘marks a new milestone’ in terms of both, the distance and power load, and verifies the firm’s space solar power systems (SSPS) concept.
 
Mitsubishi envisions SSPS will take solar energy generation to an entirely new level. Solar panels would be placed at geostationary satellites, which hang above a fixed spot above the Earth’s surface at the distance of 36,000km, and unhindered by Earth’s atmosphere would generate energy much more efficiently.
 
The wireless transmission system, freeing energy generation from the reliance on cables and wires, would then beam the energy to Earth using a microwave or laser technology.
 
Mitsubishi believes space-based solar power will revolutionise renewable energy generation and will in future become the world’s number one source of clean renewable power.

Joyce Solar Actuators are designed to precisely position smaller solar tracking equipment. Their robust and efficient DC motor (24V or 36V) keeps power consumption to a minimum. Travel speeds remain nearly constant regardless of the load. Ideal for rugged environments common to the solar industry, these cost-effective SA actuators have an IP65 protection rating. Self-locking features in the mechanism ensure that the solar actuator will hold position throughout the daily tracking cycle. Specifications: • Double clevis mounting for easy installation • Clutch for overload protection • Adjustable limit switches for flexible travel settings • Reed sensor digital feedback for accurate positioning • Duty cycle is 25% (4 min. running, 12 min. rest) • Lubricated for life
