So this combining AC and DC into a single supply, what does it do? How?

Well, the problem is that DC and AC are different.

And so various people have looked at the ways of providing both DC and AC to houses.

And the solutions which are around the people in Finland, for example, they provide DC to every house and then convert it to AC for all the historical things you have.

The Dutch have a scheme whereby they're going to put a separate network, distribution network for DC, but that entails lots and lots of cable and lots of digging up roads and disruption and so on.

In this country, we have what's called three-phase AC, which is used for farms and factories.

And our plan is to use three-phase AC for houses too.

Because it's so crucial, how would you transition to a new system?
