Toaster-sized Evapolar cools, humidifies and purifies the air
Most so-called portable air conditioners stretch the definition of "portable," but the Evapolar isn't one of them. In a form factor about the same size and weight as a small toaster, the unit packs an evaporative cooling system to cool and humidify the air, while an evaporative nanomaterial based on basalt fibers that was developed for the Russian military helps purify the air.
Desktop units that humidify and purify the air, and perhaps even offer a bit of cooling, have been around for some time. But most have a minimal effect except in a very small space – say a few meters. The Evapolar is essentially like having a mini in-window evaporative cooler that you can unplug and take with you, but it’s potentially more efficient and healthier.
The Russian team responsible for the device boasts experience in the production of evaporative materials for industrial air conditioning systems and say the evaporative nanomaterial based on basalt fibers that forms the key part of the unit has proved its worth in industrial air conditioners in the Moscow subway for a number of years.
Its creators say the 1,680-g(59 oz) unit is 12 times more energy efficient than a traditional split system air conditioner, consuming a maximum of 10 W and boasting a maximum cooling power of500 W. Running off mains power, the device itself measures 160 x 160 x 165 mm (L x W x H) and has awater tank capacity of 710 ml (24 oz), which should provide around six to eighthours of cooling. The company also claims that it can drop temperatures by a maximum of 17° C (30.6° F), but this is only in very dry and hot conditions, with the average temperature drop around 6 to 8° C (10.8 to 14.4° F).
Still with a week to run, the team's Indiegogo campaign has raised over US$160,000 of the $100,000 goal and still has pledges available at the early bird price of $179, with the retail price expected to be around $400. Currently color options are limited to black or white, but more colors are planned for the future. If all goes to plan, backers will start receiving their units in June 2016. If you can't wait, you can build your own by paying $60 US for the company's DIY kit.

It's water and a fan which is why it works only in dry environments because it is humidifying the air by evaporating water... Hardly a new idea and all they did was add fancy lights and some industrial design.
Not to mention 500 W is only 1000 or 2000 Btu/hr of cooling power, a 500 sqft room requires many times that to actually cool the space. I would love to know the test conditions that they were able to see a 17C drop- perhaps in a super dry room that was already very hot with 0 ventilation and great insulation.
Cool but highly suspect of the innovation here.
I do not in any way want to discourage but it would have been better had there been a third party endorsement at least of a prototyp.
