Solar power stations outside Earth
Solar panel arrays are being
used to power space stations for a long time, but harnessing energy
from outer space is still at beginning stage. In Earth solar panel
arrays are used to harness electric energy during the day time. A
huge portion of solar energy is lossed due to reflection and
absorption by the atmosphere.
Solar energy has to be stored
in battery to backup for times when sunlight is not available . If
space based solar stations are successful then we can harness solar
energy for 24/7. In 2015 Japanese Aerospace Exploration Agency(JAXA)
transmitted 1.8 kilowatts of energy across a distance of 55 meter
using microwaves. Safety protocols for transmitting such waves should
be taken into consideration by the nations.
There is still a long way to
go to achieve this but if proper resources are available then space
based solar stations can provide remote electricity to anywhere on
Earth.
