In this report – a serious viewer suggestion: We examine the viability of re-charging the caravan’s battery using a homemade wind power generator strapped outside the van, as you cruise. What could possibly go wrong?

Some sites don't have mains power hook-ups, or maybe not enough available. Modern caravans need power for all sorts of things, eg pumping the water, running the gas central heating and lighting.
Solar panels can work quite well, but additional batteries present a few problems, mainly where do you put them, is there space? And with the added weight are you overloaded? If not can you balance the nose weight? Some caravans are not very well engineered like that but it is quite a juggling act.
I'm not familiar with the Hyundai's system. But the modern electrical systems I know tend to run at relatively low voltages, 12-12.5 volts going up to 15v on overrun. With the voltage drop across the van, effectively you can be discharging the battery in the van over the length of the journey. Having said that, turning the head lights on tends to up the voltage to a more suitable level.
That said, where can I sign up for the boobie screensaver?
Haha after that burn I reckon Rob unsubscribed faster than a virgin looking at a ming mole
Maybe he needs to take the hydroponic system out of the van🌿
The alternator is smarter than the author me thinks 😂
Honda have gas generators from 0,5kw to like 20kw if that doesn't floats your boat ask caterpillar they have like 3000kw ones. If you really want to run that barbeque really hot General electric is your choice, they have gas turbine powered pure beast mode 600 000 kw monster.
4:52 There might, unfortunately, be some truth to that statement :/
13:29 those aren't props, they're compressors. Low pressure, high flow, intended to generate maximum mass flowrate (see thrust equation). Easiest way to tell is by looking behind the rotor. On all of these engines you will find compressor vanes. These take the angular momentum out off the gas and do the rest of the compression. As it's only a single stage axial compressor, the absolute best pressure ratio you can hope for is about 1.3, however since there's no flow restriction (and since you'd really rather have no dP at the other end, again – see thrust equation) there isn't any compression either. It's just a very big, very high flow pump.
Low bypass turbofans, intended for supersonic applications, tend to have multiple stages of LPC and a de Laval nozzle at the end. The throat of the nozzle chokes the flow, limiting it to the local speed of sound, which allows compression to take place (hence the multiple stages). The expanding section following that essentially converts all that heat into momentum by accelerating the gas past the speed of sound.
In contrast, a prop is just a rotating wing. It's built to rely on the lift it generates as a spinning wing, so there's no mitigation in place for tip vortices, no flow conditioning after the blades and they tend to be limited to subsonic tip velocity, which limits their usefullness.
Kinda lost track of what this video was about at the 6 minute mark, something about tits?
I think you were a bit harsh there John. The guy asked a question and got his pants publically pulled down!
Hahahahahaha! "Huon Pine box" . . . "bury me DEEP at Maralinga" . . . too funny!, always good to end the vids with a good giggle! Thank you John, your wonderful and funny 'public service' videos are always very much appreciated – much more now in fact with the recent idiocy pervading our world. Thank you – don't ever stop. Wish you every success in your business through this uncertain time ahead.
