Beaming energy to Earth from space has been more chat than reality over the decades. But things may be changing.

First, look for a National Press Club address in Washington, D.C. this Friday that will detail a demonstration project concerning point-to-point wireless power transmission.

What’s being spotlighted is a project that involved a wireless power transmission effort between two Hawaiian islands 148 kilometers apart - that’s more than the distance from the boundary of space to the surface of Earth.

The press event at the National Press Club is being hosted by the National Space Society.

For those folks that have not been given a positive charge of advocacy regarding satellite solar power, the key idea is that space-based solar power satellites in Earth orbit would harvest plentiful solar energy in orbit - then convert that energy for transmission down to terra firma for distribution over power grids.

Such spacecraft, it’s hoped, would help reduce our carbon emissions to virtually zero as proponents showcase the idea as the only energy technology that is clean, renewable, constant and capable of providing power to virtually any location on Earth.

By the way…that Hawaiian demonstration is to be featured in an hour-long special Friday night on the Discovery Channel - one small part of an eight-part series on geoengineering concepts meant to tackle global climate change - as well as pushing new and sustainable energy source concepts.
