The Consumer Electronics Show is going on right now in Las Vegas, and there are some cool gadgets coming out - like a shower head that helps track your water usage while in the shower.

According to a Mashable article featuring the shower head, called Hydrao Smart Shower, connects to an app that lets you set three different alert intervals for gallons used. For each of those set intervals, the shower head will light up three diferent colors as warnings.

Here's what makes it even cooler - it doesn't run on batteries. It has a small turbine inside of it that draws its power from the water flowing through it.
