Understanding of the principles useful for life, but to work effectively with devices perhaps not necessarily.
Now about the difference of versions - a lot of homemade products will not give you the efficiency that you can get a "factory" method. I have other production capabilities, i.e. the conditions for making that impact on the efficiency and on the knee not to repeat in any way. But in many cases it is possible that handmade enough for tasks (e.g. with family).
The reason for the publication is simple - as with version 1.0 using I the interests of the environment and society care about themselves, somehow influencing the world in which they live.
There are certain processes that destabilisateur it. This is normal. The bad thing about what I wrote - in the minds of people advertising camel

in the picture of the world and the cows from the "buttermilk" - they pick the wrong picture of the world themselves and contribute in their places of accumulation of ADDITIONAL chaos into the world.
It's just man-made dangerous.
If you stabilize even the rare individual points, this slightly stabilize the situation in General - you know, like a patch of broad ties to patch...
The device contains many elements that promote it in large quantities to the world of commercial long, tedious and useless. To buy will be those who need a high efficiency and it is justified from the point of view of a ratio the price quality.
But homemade will do the rest.
It's just different niches and to each his own.
BJ 1.0 long been available for free and works great... I haven't laid out the charging system 1.0 in order to sell the older version, them then not. It happened.
The stabilizer is now urgent, so I'll go in accessible.
By the way this even has a beneficial effect on society as a factor in the introduction of "everyday magic"

Yes. I understand that it is not comparable with the population, but I don't have super purposes, it is enough to run what I was capable of at the moment.
Just money you can earn and spend, and conditions of life - they are long-term, because incomparably more important.
It is worthwhile to keep a healthy balance.<
