There is much talk that we should conserve water and energy to save the planet. Usually, this involves sacrifice. Let’s face it, apart from masochists, most of us do not like sacrifice. But there are some great energy saving ideas that allow us to conserve with no sacrifice.
A simple idea is to shower like a submariner. We are all told we should shower instead of taking of a bath to save water. This saves some water. But occasionally when I have stayed in a hotel with a shower in a bath I have put in the stopper to see how much water I used. Often my shower will more than half fill the bath. There is a water saving for showering relative to filling the bath but it is not absolutely massive.
But when showering on a submarine or other naval vessels you have to conserve water. Fresh water is scarce on any sea vessel especially submarines. On ‘Das Boot’ and other WWII submarines there were no showers and sailors shared bunks sleeping in 3 shifts, but modern nuclear submarines are not so cramped. But they can be underwater for weeks on end without surfacing so they do need to conserve fresh water.
So how do they shower? Turn on the water and wet their bodies. Turn off the water and shampoo and lather up. Turn on the shower again to rinse and that’s it. There is a major water saving because the water is not left running while lathering. There is the added benefit that half the soap isn’t rinsed away before it has a chance to soak in properly.
I have started to use a variation of this technique and am saving lots of water, and more importantly, the energy used to heat it. In high summer my solar panels produce enough hot water to waste but now after the autumnal equinox, I have to supplement the solar energy with expensive oil water heating. I wet myself, turn off the water, shampoo and lather, rinse my hair and face only, turn off the water, add conditioner to my hair and rub it in, turn on the water slowly to rinse my face and off again, rub shaving oil on my face, turn on the water slowly to rinse again and shave. Finally, I turn up the water full blast and rinse the conditioner from my hair and the soap from my body.By learning to use the on off knob in the shower I am saving lots of hot water and it is no sacrifice! Save water and energy. Shower like you’re in a submarine!
