BluArmor’s cooling technology mimics the human body’s approach to heat removal by using water, but with a twist – it cools a confined space, and continuously flows enough air in that space at temperatures below the skin temperature to accelerate heat removal. Think about it this way – if I had a fan next to me blowing air at temperatures lower than my skin temperature, wouldn’t I be at peace with the weather? The worst-case scenario for any water-based cooling solution is a hot and humid place where the air already holds a lot of moisture. Hence we ran a lot of our field trials in Chennai over the past summer and validated the technology through rider feedback and cooling measurements. We achieved 8-8.5 degrees of cooling when the ambient temperature was 38 deg C - keep in mind that the skin temperature is typically between 33-36 deg C. With BluArmor, water does most of the work in heat removal, and the electrical energy consumed is low. We are able to achieve cooling capacities of >20W while consuming ~0.8W of electrical energy allowing our cooler to operate from a rechargeable cell phone battery making it ultra-portable.
The body is very effective at maintaining its internal temperature by exploiting any and all heat-removal paths made available to it. We are all familiar with a number of localized cooling methods like splashing water on one’s face on a hot day, putting a wet towel around one’s neck right after a game, and using a table fan that directs/circulates air around one’s head/face. None of these approaches have any detrimental health effect because they all assist the body in what it’s trying to do – lose heat. ACs (and the like) can be discomforting if the directionality is poor; cold air directed at one’s temple, for example. We flow air at a temperature that is few degrees below the skin temperature and direct it in a way that it distributes better around the rider’s head/face thereby avoiding the irritation that comes with poorly directed air flow. Our body has such an uphill battle to fight with heat removal when we are outdoors that it thankfully accepts any help we can give it.
The cooling filter we use comes with anti-bacterial coating that eliminates germs and moulds. It also absorbs the virus and scale in the water preventing harmful air from being released at the outlet. A video showing how to clean the filter periodically will be made available on the webpage before the product is delivered.
You can expect ~10h of run-time on a full charge.
We don’t have a visual indicator for tank-empty in BluSnap. A full tank will give you about 2 hours of cooling, and we recommend that with BluSnap, you fill the tank before you start on your commute. We are also developing an integrated helmet that comes with advanced features like intelligent fan speed control (based on driving speed), water-level indicator, fan-speed change through voice commands, etc.
That’s an interesting question! While the product has been designed to fit existing helmets, we have made some design choices that allow consumers to get creative with how they use the product. BluSnap comes with an elastic band that makes it easy to snap it on to most surfaces. BluArmor’s technology is very powerful in how it aids the body in heat removal, and while we work on our roadmap in offering variants of BluSnap for different use-cases, we will be more than happy to watch how our consumers are putting this product to use.
