MM,
Before we get too exited about savings by using DC instead of AC, we might
look at where and why we have this large differences in the energy use by
appliances. Let us first establish the fact that a conversion as such, will
cost us between 3 to 10%, depending on method, size and

Each of these conversion actions may have
consequences in terms of lost energy, but I haven't yet figured out
the losses. This has come up for me

The reason why I ask, is to know what could be gained by only a storage
solution, by utilizing rate differences. If you have low rate prices, they
are normally 50-60% lower than normal rates. With a battery storage
solution, would it be feasible to charge during discounted time and that
way

I have done some superficial research, and my preliminary conclusion is that

is the determining factor. For household-scale energy storage, batteries are
the
most economic solution for storing electricity. I did some rough calculations,
and
concluded that with realistic

could you discount the alternative of hot water storage in large, insulated
tanks if the energy is to be spent in an hydronic system for a combination of
space heating, swimming pool heating, and heating the driveway

Glenn,
I do not think that water storage was excluded. Darryl also mentioned the
building mass, which most people forget. It is solutions with storing heat
in water and at the same time wasteful systems who are working on
eliminating the influence of building mass. The discussion was about
