There is an Alternative Way of Battery Power - SALT & SAND!!!

UTL COMMENT:- Green energy is a SCAM, however since we all have to look at prepping, this is quite interesting......

How the world's first sand battery stores green power - BBC News
The world's first fully working "sand battery", which can store green power for months at a time, has been installed by Finnish researchers.
The developers said this could solve the problem of year-round supply, a major issue for green energy.
Using low-grade sand, the device is charged up with heat made from cheap electricity from solar or wind.
The sand stores the heat at around 500C, which can then warm homes in winter when energy is more expensive.

Homemade Salt Batteries running Thermo-Electric fans! Easy DIY! Salt & Sand Batteries.
Homemade Salt Batteries running fans! Salt Batteries are easy to make and can power a variety of Thermo-Electric Device's and in this video it will show two DIY Salt Batteries running several thermoelectric fans.

Here in the video they use HEAT POWERED FANS.
The fans themselves create their own electricity using the thermal energy stored in the Salt that electricity is then fed into the fan's motor which turns the blades. Note that sand can be used in place of the salt.
