Do you mean the overall feel or actual electrical power?

Or are you talking about the fuse box / electrical panel for the entire house?

overall feeling....i hear about that some objects or shapes can take energy from nature.

The products we design now are made with new stuffs. Service layers, video, animation, subscription models, customization, interface, software, behaviours, places, radio, data, APIs and connectivity are amongst the immaterials for modern products.

Immaterials are the new substrates for opportunity and risk in product design.

Making the invisible yet physical visible – the miasma of frequencies and info flows we unavoidably wade through everyday – for better or worse

Are we talking Feng Shui, physics, geothermal or solar energy? Just curious. In other words...what are you hoping to achieve?

Get rid of your florescent light bulbs and put the old fashion light bulbs (incondescent) back in. Put in dimmers to save energy. The warmth of the light will make you feel warmer. The cool lighting from the florescent bulbs make your rooms feel cold and dreary. Zapping all the energy out. Keep out clutter as it will cause irritability in a room. Use monochromatic color schemes (various shades of the same color) for a soothing room.

i am talking about natural energy, in our nature there is positive and negative energy. some objects or shapes absorb negative energy.

This sounds more Feng Shui to me...am I on the right track?

i think ,, tell me more about that

I am fairly ignorant on this topic, but have heard that quartz crystals are used for positive energy. I have also heard that decluttering helps positive energy flow. There are many articles and info on positive energy and Feng Shui to be found simply by "googling"...I would do that..and maybe someone else has something to share. Wish I knew more to tell you, and good luck..For me music and people I love brings me positive energy.
