With all the emphasis lately on “going green” and energy-efficiency, we love this forward-thinking company and it’s new air conditioner. It’s the Millennia version 4 from SolCool One, a “hybrid” air conditioner that can cool a large room using solar panels, a wall socket, or even batteries for when the sun takes a vacation day. Because the system utilizes a maximum of 500 watts, the Millennia significantly lowers your electric bill—regardless of the power source (the batteries can run the device up to 24 hours). In addition, the Millennia can also heat up a room, purify water and even run other appliances. It is foreseen that if solar-powered air conditioners catch on in homes and buildings, the risk of blackouts in the summertime would be greatly reduced. The SolCool Millennia version 4 will be available in Mid-April for between $2000 and $3000 USD, plus installation, with benefits that far outweigh the costs.
