What's an (allegedly) easy way to reduce your energy use? Dry your clothes in the great outdoors.

The first of it's kind. A laundromat supplied with solar power, significantly reducing dependency on the grid.

We find these little nuts interesting (and also wonder who discovered them) but apparently you can use them in your washing machine in lieu of detergent. SoapNuts are the shells of a seed from trees grown throughout India and Nepal. These shells give a soapy substance when they come in contact with water (the seeds are discarded) and it's said that 1kg of the nuts can wash 100 loads. Simply pop 6-8 shells in the cloth bag and throw them in your washing machine – these will last about 3-4 washes. Your wash will come out clean, but without a smell, so if you like the scent of clean clothes just add a few drops of essential oil to the wash beforehand. SoapNuts can also be used for other things as well, like washing windows, cars or pets. When the shells have been used to their full extent just throw them in the compost pile.
