The brain consumes about 25 % of the body's energy when at rest.

So for a typical person, on an average day, this equates roughly to 24 watts (based on 2,500 Calories/day).

But the energy usage of the brain does vary depending on the level of mental exertion. Studies have shown that when performing difficult mental activities, the energy usage of the brain increases.

About 10-12 watts, so not much. But to use that power would leave next to none to run your body, lol. So in my opinion, unless there is a way to slowly exercise the brain, to slowly compensate and replace the energy you are trying to harness then it would be a pointless battle.

But on the other hand our body generates a lot of thermal, and kinetic energy, which could if done right be upscaled to power lots of awesome things.

If you wanted to calculate the actual Watts (W) of the brain, here are some basic assumptions that can help illustrate what the value can be.

If you assume your brain burns about 25% of daily caloric intake, which on average is 2000 Calories per day (1 Calorie (US) = 1 Kcal (EUR)). And let's use the following conversions:

1 kCal = 1 Calorie = 4184 Joules

1 Watt = 1 Joule/Second

1 hour = 3600 seconds

Then over a 24 hour period, (on average), your brain is operating at an average power output load of:

500 Calories / 24 hours * 1 hour / 3600 seconds * 4184 Joules/Calorie = 24Watts

This is an average number. At night when you're sleeping, your brain is only operating at 20% of typical power output, so it's safe to say that during your waking hours (the other 2/3 of the day, 16 hours), the brain's power output is nearing:

24/(0.2)*2/3=80W

It's like a light bulb being on all the time - hence, why your head runs "hotter" than the your body tends to be..., and why it makes sense that it is closer to the lungs than the rest of your body (oxygenation, temperature regulation, etc...)

About 25 watts.

Solar panels can make enough watts to power your whole house if you have enough of them. Some solar panels will generate 50 watts, 80 watts or 120 watts.

The DC output of the XBox power supply is 135 watts.

Horsepower is a unit of power. 1 horsepower = 745.699872 watts The formula for Power is this: Power = Work/TimeThe SI unit of power is the watt (W), which is equal to one joule per second. The SI unit for work is the joule (J). The SI unit for time is seconds (s).

Amps are units of current, watts are units of power. Watts are the product of Amps times Volts. Watts = Amps x Volts.

Power is expressed in Watts

There are no watts to generate volts!! There is a relation that is watts = volts * Amps Generators are set up to generate a specific voltage regardless or watts or amps capacity it has.

A panel does not generate any current, the generating happens at the power plant. A 280 watt panel on a 120 v supply can supply up to 2.3 amps.

Your brain can power up a 40 Watts lamp (for as long as it lives). I really don't have the proof of this, but it's something a professor of mine told in the class of Pattern Recognition the other day (because we were talking about neural networks).

First calculate the power: P = I2R. Power will be in watts. Then multiply power x time to get the total amount of energy transferred. If the time is in seconds and the power in watts, the energy will be in joules. (In this case you need to convert the time to seconds first.)
