  • GAN is not just faster and smaller, it’s side effect is also efficiency.

    But it’s currently still a high end way of going power switching. So it’s more expensive, so not all power supplies use it yet

    House power wise our biggest users are AC appliances (heat pumps) they do not benefit from a more efficient DC adapter. Power chart

    A phone at 5000mah who charges every day from 0-100% would use 5Ax4.2Vx365d = 7,665 Kwh x €0,22 = €1,68 (excluding efficiency loses). This is too small to make reasable investments in phone adapters. But I do see that a better computer power supply (when use regularly) can make a difference to your power bill







  • For anyone looking for some cheap help tips:

    1. Block the sun from comming in, by hanging a curtain or bed sheets on the outside of the window. Of course real shutters would be even better, but price and time wise this gets you there.

    2. Close your windows in the morning BEFORE 8:30 or so. Open then after 20:00 BUT ONLY iit’s colder outside. Keep them open during the night. You can not cool a house down with warm air. Yes it’s warm inside, but it’s even hotter outside so opening a window during the day does not help you. If you like a breeze, buy a fan








  • A battery is energy per volume.

    So instead of buying a big battery, we have a small one and all the devices go along with it. The house and water is heated when the battery is charging. And the setpoint is lowered when energy is expensive.

    This extends our our “battery capacity” without the investment into more electrical batteries
