About 7.5 kilowatt hours is needed to charge the Powerwall, providing about 6.5 kilowatt hours of power once charged. With some utilities, consumers can choose between flat-rate electricity pricing (the price is the same no matter the time or day or demand on the electricity grid) and peak-rate pricing.
Myth or Truth: I need 8 glasses of water a day. Myth. The Institute of Medicine says adult men actually need about 13 cups (3 liters) per day of fluid; adult women need about 9 cups (2.2 liters) of fluid. (You get about an additional 2 1/2 cups of fluid from foods.).
The old adage of 8 glasses a day is no longer true. Instead, think about how much you weigh and divide that number in half. That's how many ounces of water you should drink per day. For instance, a person who is 200 pounds, should drink 100 oz. of water per day to be adequately hydrated.(That's 12.5 glasses of water!) An athlete with a high level of muscle mass should drink even more, about two-thirds of their body weight in ounces per day.hat's how many ounces of water you should drink per day.
