Did you know the US state of California produces so much solar power they have to PAY other states to take it? Granted some of that is due to contracts with existing power companies.

This is Quint BUILDs entry for the #VeritasiumContest. Contest details: https://www.veritasium.com/contest In case it wasn't clear from the video, the smaller battery has a higher voltage, but that just means the bulb will "eat" through it even faster than if it were the same voltage as the larger battery. Key takeaways: - Higher voltage (V) pushes more current (I) thru the same bulb (V=IR or I=V/R, Ohm's law). - The smaller battery is a stack of many tiny sandwiches (higher voltage) which gets "eaten" very quickly. - Current always completes a circuit to ground (bulb was pooping ground symbols). Not covered: - Battery capacity is rated in amp-hours, but this is not a measure of power or energy. - Power=Volts x Current (watts), Energy=Power x Time (watt-hours) - Battery chemistry (Alkaline vs. Nickel or Lithium) affects battery capacity significantly. - Cheap battery brands often lie about capacity, so buyer beware! - Batteries often don't include rated capacity on the label. Rather they publish runtime charts under various conditions on their websites. Derek is a man after my own heart, exploring and sharing, even when the results are controversial. What a cool way to capitalize on his bet, generating a surge of short STEM videos online! What do you think, should I do more videos like this one? It was a lot of work cramming that much information into 60 seconds but I enjoyed every moment!

One of the first father/son projects we ever did (2015). Thought I'd release it on this channel and see what you all think. Though it does run purely on solar power, the 60 watt panel is not enough to run the 150 watt motor. Thus it has a ridiculous amount of battery storage that after a day of charging can run the thing in the dark if necessary for a couple of hours. It can do that as fast as I can sprint which means it leaves me behind about half way around a track. When we took it to a track it maintained 11 mph (18 kph) until the plastic hubs started to melt. I've since upgraded all hubs with bearings but haven't done the speed test again to find out how much faster it goes.

How much wind power can you get on a car? In this video we go into the theory of calculating wind power and how the Betz limit restricts us to just 59% of that. Then we go for a drive with two different wind turbines and measure how much power they're able to output. If you missed part 1, check it out here: https://youtu.be/MlwK4kCrXB0 I expect this to be at least a four part series and will try to get a part published each month. It's going to be a lot of work but I hope to stick to the one-video-per-month cadence if I can. Wish me luck! Quint A huge thanks to my super awesome Patreon supporters who made this video possible.

Can a wind turbine in front of a car harvest FREE energy? This question came to me during a long drive my final year of engineering school. Now we're going to find the answer. Part one explores the fundamentals of wind turbines using the principles of wind on your hand. In part 2 we'll dive into how much power is available and the theoretical limits on what we can do with it. I expect this to be at least a four part series and will try to get a part published each month. It's going to be a lot of work but I hope to stick to the one-video-per-month cadence if I can.

This is part 4 of my series on generating power from rain gutters. We're not just squirting water on a propeller, I show how to calculate the power available and harness an increasing percentage of it.

A lot of engineering involves iteration. In this video I iterate through several turbine designs, searching for the most efficient conversion of the water jet to mechanical power. The logic that a smaller diameter will spin the generator faster, quickly runs up against the total power available and efficiency of the turbine itself. Lesson learned: power generation is not as simple as we'd like to think!

Though I calculated 2 watts of available power and planned on only collecting 50% of it, the actual output was only .19 watts. In part 2 I design and build a permanent magnet alternator then rectify the AC into DC power to enhance the efficiency. In part 3 I iterate nozzle and turbine designs to see if we can get a full watt of power.

A lot of people wonder if there's any power in the rain falling on our roofs. This video series starts with the theory of how much power is available then attempts to achieve it in practice. It was a lot of fun to BUILD, hopefully you enjoy it and learn something in the process. For those in the comments that insist I didn't compensate for the angle of the roof in the rainfall calculation, did I not say "once I calculate the horizontal distance..."?

I want to have the option of taking a month off and not keep taking your money just because another month has passed! Thanks for watching... -Quint Harvesting hydro power from rain gutters! It sounds impossible but it works. This is part 1 of a video series on the theory and implementation of capturing hydro-electric power from the roof.

This video is for educational purposes only. Do not attempt to replicate anything you see. The warnings and examples of injuries and destruction of property are there to educate you about the dangers of flammable gases. Static electricity really can detonate flammable gases like acetylene so don't mess around with it! Oxy-acetylene welding itself is extremely dangerous and should not be attempted by unqualified individuals. I intentionally did not detail the many safety precautions I took nor the actual filling of the pumpkins because I don't want anyone to be tempted to try it themselves. There are plenty of bad examples on YouTube with little if any educational value and I will not be included in that group. If you just want to see the biggest boom, step forward to 5:12. To learn more about Gustaf Dalen see Wikipedia article: https://en.wikipedia.org/wiki/Gustaf_Dal%C3%A9n He was such a badass inventor that he kept on inventing even after losing his eyesight to an explosion! For anyone interested, the reason acetylene is so powerful is the triple bond between carbon atoms. Propane only has a single bond between carbon atoms but can still do plenty of damage. Calculating the "enthalpy" of the chemical reaction predicts a greater release of heat with acetylene than other gases because of that triple bond. One of the many things I learned making this video is that propane is used professionally to cut steel like acetylene, it just isn't as hot and requires more oxygen to do it.

I've been topping off a leaky tire for weeks and staring at my garden hose wondering if I could use it instead of my compressor. The answer is YES!!! The goal of course was to make a video demonstrating a clever use of physics to solve a common problem in a creative way. In no way do I actually recommend this as a practical solution! At some point I will create a video explaining the calculations and post it on my 2nd channel, BUILD2. When I do I'll put the link here.
