Aquapod Emergency Water Storage is a low cost way to safely store 65 gallons of clean water, a 14 day supply for a family of four.
Not exactly an overlooked innovation since the plastic technology to make this cheap is fairly new. This does use an existing resource, the bath tub, to provide the strength to store the water which weight 520 lbs (236 kg). Using the bathtub this way allows the Aquapod to be much thinner plastic and thus lower cost. It also uses a space which won’t be used during an emergency. If the water is not running the bath tub won’t be used so storing water there does not take up extra space. Furthermore it uses the readily available supply from the faucet, assuming to have time to prepare for an outage. The kit comes with a hand pump making it perfect for use when power is out.
