/diy/ - Do It Yourself

Looked again at the EcoloBlue site. The package deal on their most expensive model is $4300, but you can buy the 7 gallon (26 liter) version standalone unit for $1000. You don't need an inverter if you're running everything in your compound on 12V DC. The panels you can buy your damn self for $1.10-$1.15/Watt wholesale. Unless you were planning on having the machine make water at night, you don't need batteries, but you can get Edison cells yourself at 6.6 Watts/$ if you wanted to.

My point is you can get water from the air for cheap, only $1000 for the actual device. The rest (batteries and panels) you were going to buy anyway. Note this is 1/3rd the cost of a new refrigerator.

My question is, if your whole house is running 12V DC, do you need a power supply unit for your computer? How would that affect your average laptop or desktop?
