The AquaPak is a small device that can pasteurize water. The pack uses solar energy to heat the water that has been placed inside up to temperatures to pasteurize it and thus make the water safe for drinking for both those out enjoying the great outdoors and for those that lack any other source of safe drinking water.

In many countries safe water is a large issue. Many thousands of people die each year due to the pathogens, the bacteria,viruses,and parasites, etc, like cholera and salmonella that can be found in the water. This issue is more significant in the poorer, rural areas of certain countries, because of this effective methods for creating safe water with devices that are affordable have been few and far between. This solar powered pasteurizer should eventually cost only around $2 to produce due to its manufacture. It is constructed from cheap, robust materials, for example low cost polyethylene plastic and bubble wrap is part of its construction. The pack is strong enough to survive a 10 foot drop test, due to the bonding of the plastic at the edges with tapered seals.

In laboratory testing the AquaPak killed 99.99% of the pathogens that were present in the water. The pack achieves this by using solar energy to get the temperature of the water inside over 65 degrees C. The pack can take 4 to 5 liters of water at a time and it can take around 2 hours to reach pasteurization temperatures, simply fill it with water and lay it down flat in the sunlight. The pack can be refilled many times a day, allowing it to pasteurize enough water for a family of four to use in countries with bright, hot days.

The AquaPak has an indicator to show when the water has reached the correct temperatures. To save on costs the pack uses a WAPI (Water Pasteurization Indicator) which is a small low cost glass tube that contains bright orange soy wax. This wax has a melting point that is equal to the temperature needed to pasteurize water. When the wax has melted you know the water inside is now safe for consumption.

The AquaPak is a cheap and simple method to provide safe drinking water to many people, thus significantly reducing needless deaths. The AquaPak is available for sale in many countries for use by those that enjoy life outdoors, for example camping or hiking. It allows them to reliably and efficiently rid the water they collect from rivers or streams etc from any pathogens.

The AquaPak Water Pasteurizer is just $26.99.

The Hydropal Filter Water Bottle is a simple idea that could have a large impact on both your wallet and the planet. The bottle filters water so you can fill it from any tap and get that fresher filtered water taste at any time.

Tap water is often said to have a taste, anything from ‘odd’ to ‘horrible’ . The Hydropal filters out many impurities, volatile organic compounds (VOCs), chlorine, pesticides, herbicides and many other man made chemicals are all removed, though thankfully fluoride is left alone.  This then takes away the odd odors and tastes from the water making it fresher tasting.

The filter uses activated carbon to absorb both chemicals and solids in itself. The polymer filter has been impregnated by a high concentration of activated carbon which basically is carbon that has been carefully treated to make it highly porous. The high levels of micro-porosity in the activated carbon give it an extremely large surface area which allows it to act well as a filter, absorbing the impurities in the water easily.

The Hydropal Filter Water Bottle has a non spill cap and holds 750ml of water. Each filter should last 250 refills or up to 6 months. Extra filters are easily purchased for the bottles prolonging the life of the bottle and so reducing the amount of plastic thrown away significantly. The bottle itself is even made from 35% recycled plastic. For those currently buying bottled water this water bottle offers a way to save money and reduce the amount of plastic being sent to landfill (or to be recycled).

Prices for the Hydropal Filter Water Bottle are around £10.

When you evaporate and condense water, the condensed water is 100% pure water. This means the purified water is completely safe to drink, as nasty chemicals and bugs do not evaporate with the water. The WaterCone is a very simple gadget that purifies water by the process of evaporation.

Water is poured on to the black tray. As water evaporates, it condenses on the inside of the clear plastic cone. The condensed water then runs down the sides of the cone into the outer tray. When the outer tray is full, you then drain it into your water vessel of choice.

The Water Cone can hold up to 1.7 litres of dirty water at a time, and it only takes a few hours for the water to be condensed. It costs around $30 (even less with mass production I’d imagine), so is easily cheap enough for mass distribution. The cone is designed to last about 5 years, so that’s a great level of usage for a very low-tech water purification eco gadget!

Petra Wadstrom is a Swedish inventor has developed a solar-powered water purifier that could provide billions of the world’s poorest people with access to clean and disease-free drinking water. The purifier treats 10 litres of water at once, all within a compact case. The cost of the unit is to be set at around just $35, which would make it very affordable for many aid agencies.

The Solvatten uses solar energy to treat the contaminated water with ultra-violet (UV) rays. The UV rays essentially render all bacteria and viruses inert. The purifier does not need any special technical skills and is completely portable. The price, ease of use and portability make it a great device for developing countries who need access to safe drinking water.

The SteriPEN is an eco-friendly gadget ideal if you’re travelling to areas with typically unsafe drinking water. The SteriPEN will allow you to refill your water bottles (rather than buy bottles from a shop) and ensure the water is safe before you drink it. The pen uses shortwave ultraviolet light which damages the DNA of bacteria, viruses and protozoa, rendering them harmless.

It takes just 45 seconds to sterilise 500ml of water. A single charge of 4xAA batteries can treat up to between 90 and 105 litres of water. If you use a rechargeable battery (such as with a solar charger), the SteriPEN is completely portable and green.

The SteriPEN costs around $90, or about £50-£70 in the UK.
