AI Thread Summary
To build a powerful single-celled battery, using easily accessible metals and an electrolytic solution is crucial. Sulfuric acid is suggested as a strong electrolyte, but alternatives like citric acid or lemon batteries are also considered for simplicity. Aluminum-air batteries are recommended as a viable option, potentially offering higher voltage and current. Comparisons between aluminum-air and citric acid batteries highlight the need for experimentation to determine the best performance. Overall, the project encourages exploration of various materials and methods for optimal results.

Hey guys, I'm new to this forum and I've been meaning to start a project of my own. I want to create a homemade battery that gives me the highest voltage and current I can have using only two-three metals and an electrolytic solution. It can only be easily accessed metals, as I live in a city and my biggest provider for materials and such is "Home Depot." Is sulfuric acid the best solution to use for this? Is it best to just go with a lemon battery instead? Thank You, I appreciate any help!

Try aluminum-air batteries:

How would that stand compared to a citric acid battery?
 

Thread '1:1 versus 2:1 Mechanical Advantage debate'

The rope is tied into the person (the load of 200 pounds) and the rope goes up from the person to a fixed pulley and back down to his hands. He hauls the rope to suspend himself in the air. What is the mechanical advantage of the system? The person will indeed only have to lift half of his body weight (roughly 100 pounds) because he now lessened the load by that same amount. This APPEARS to be a 2:1 because he can hold himself with half the force, but my question is: is that mechanical...

Thread 'Average velocity as a weighted mean'

Hello everyone, Consider the problem in which a car is told to travel at 30 km/h for L kilometers and then at 60 km/h for another L kilometers. Next, you are asked to determine the average speed. My question is: although we know that the average speed in this case is the harmonic mean of the two speeds, is it also possible to state that the average speed over this 2L-kilometer stretch can be obtained as a weighted average of the two speeds? Best regards, DaTario

Thread 'Newton's first law?'

Some physics textbook writer told me that Newton's first law applies only on bodies that feel no interactions at all. He said that if a body is on rest or moves in constant velocity, there is no external force acting on it. But I have heard another form of the law that says the net force acting on a body must be zero. This means there is interactions involved after all. So which one is correct?
