I’ve been testing the Air Jet showerhead, and so far I’ve been impressed. This is low-flow showerhead, but it creates a high pressure shower experience using simple physics.
Flow batteries are a unique kind of battery — they have tanks that hold hundreds of gallons of the chemicals, called electrolytes. Flow batteries just happen to be very good at storing solar or wind power. Renewable power sources suffer from being intermittent, and less reliable for continuous power supply than coal or gas. Neither… [Continue Reading]
King Island is a small island off the Australian coast, near Tasmania. King Island isn’t connected to the mainland power grid, and apart from its own small wind farm it relied for a long time on diesel generators for its electricity. That changed in 2003 when the local utility company installed a mammoth rechargeable battery… [Continue Reading]
Gravity filters are more effective than other types of water filter, because the water drips slowly through the ceramic elements, and this process removes almost all the contaminants in water. The filters can be cleaned with a toothbrush and last for up to 2,000 gallons. This Berkey Light filter uses Black Berkey elements, and they… [Continue Reading]
Early on, low-flow toilets got a bad rap — and justifiably so — their flushing ability left a lot to be desired. But today there are many low-flow toilets on the market that work well. Terry Love is a plumber who reviews low-flow toilets. He takes his job seriously, installing some of the toilets his… [Continue Reading]
Have you ever spent time at the sink, judiciously adjusting the hot and cold water, to achieve that happy medium between “cold” and “scalding hot”? Well, we’ve been there too — and we’ve noticed that water streams down the sink in a meta-inefficient manner. That’s why these faucet restrictors are so handy. They attach like… [Continue Reading]
This was my first low-flow showerhead, and it’s still one of my favorites. The Earth Massage showerhead produces a fine spray or pulsing jet but only uses 1.75 gallons per minute. It works consistently in both low and high water pressures. A “soak and soap” button reduces the flow rate to 1.0 gpm for soaping… [Continue Reading]
