There are not really that many circumstances when one would require a battery free water purifier. Although the albeit limited occasions you may require to purify water without the use of electricity, the SteriPEN Sidewinder, may prove invaluable.
Claiming to be the “world’s first battery free water purifier”, the SteriPEN Sidewinder, with its ability to sanitize water with the crank of a handle, would make a great accessory for outdoor enthusiasts. As campers, travellers, mountaineers, or anyone exploring the off-beaten track, needn’t be worried that they may be drinking water laced with a tinge of goat faeces, and can almost immediately quench their thirst by purifying water from lakes, streams and rivers. As the SteriPEN Sidewinder, thanks to a UV system that destroys waterborne viruses, bacteria and protozoa, can sanitize up to a litre of water in just 90 seconds.
Being lightweight and portable, this eco-friendly product has no filters to clean or parts to replace, and will sit snugly beside the camping stove, Swiss army knife and sleeping bag in your rucksack. Excitedly musing over the Sidewinder’s unique capabilities, the SteriPEN website states:
“We wanted to create a product with the same reliability our customers have come to expect from steriPEN, but untethered from batteries. With a lifetime of 8,000 treatments and no replacement parts necessary, sidewinder is ideal for extended trips, and an ever-reliable tool for emergency preparedness.”
Although with a price tag of £150 we suspect that many campers may still ‘chance their chocolates’ with goat-poo infested water, or adopt the painfully slower but significantly cheaper method of boiling water on a camping stove, letting it cool down and then drinking it. Having said this, we also suspect that given the current trend for festivals such as Glastonbury to be full of the well-off middle classes, the SteriPEN Sidewinder may be a common feature at this year’s Glastonbury – Although spending 150 quid on a battery-free water purifier to sanitize water from the streams of Somerset, would probably work out cheaper than forking out for the obscenely over-priced bottled water at Glastonbury. Hmm, room for thought…
