Watt hours is simple to calculate:watts = voltage X amperage. Assume 12.8 volts for DC and 120 volts for AC. DC is actually more complicated, since voltage can drop as low as 11.4 volts iflead acid batteriesare drained down, which can also make the inverter conk out. Accordingly, if the...
A RUDN University physicist has developed a formula for calculating Hawking radiation on the event horizon of a black hole, which allows physicists to determine how this radiation would be changed with quantum corrections to Einstein's theory of gravity. This formula will allow researchers to test ...

There's got to be a ton of inefficiency caused by charging and discharging the batteries all the time. The design circling around a portable battery also makes it pretty power thrifty at the same time. Just curious as to how it actually pans out. Laptops have typically been more robust in...
