Lunar manufacturing will drastically reduce the cost of supplying Mars.

Very informative, thank you

When i was building Am transmitter.I use something like those to modulate the singal without being interferenced by main transmitter!

If you want to go sightseeing, go sight seeing. If you are going to get somewhere, then "stop to smell the roses" isnt a a positive.

Good idea, but you are missing a feed back loop to avoid oscillation at the switch point - and have a bit of hysteresis. Note that the LED lit up slowly proving my point. Btw. that 7 mV measurement across the 4M7 resistor - that does not compute.

Could you instead of the LED hook up the LED of an optocoupler and use it to drive a relay that would disconnect the load from the supply?

oh wow nice, didn't know that. A Schmidt trigger behind that and that would be perfect for my application, thanks.

Could you explain more about how this robot works? I'm doing a school project and wanted to use your project as an example. Thank you for your attention🙏🏻

My v w turbodiesel gets fifty five miles to the gallon and seven hundred miles per tank. Tesla 300 mi range and 30 min charge? I doubt 80% range is 300 and charge takes 30 min. Ha ha ha ha. Sure. You will add a day in Tesla. My Diesel is CHEAPER TO DRIVE. At $3.50/gal my cost $0.069 mile. You day 0.06 gor Electric? I doubt it.

Where and when can we source?

I felt asleep listening to presenter

Why is there a spectrum analyzer in the thumbnail lol?

Congrats on your channel. Go buy a microphone. Cheers.

Cool beans, Jon!

YOU NEVER STOP AMAZING ME JON..WOW😎

very well done

This is very well presented.

pete port here good to see u hope all is good

In addition to being a good bass player, you are also very intelligent.

Looking at the picture its almost certainly non isolated. Look at those big fat torrids! Smells Continuous Current Mode of some flavor. 4 channel synchronous buck boost converter perhaps. Inherently bidirectional and unfortunately non isolated.

more hand movments then details

What was she actually selling to us? Religion?

Blah, blah

An input of 12VDC significantly enhances energy efficiency with a 12VDC output load, enabling reduced system complexity while supporting sustainable 12VDC power solutions.

There is no need to add this many cuts between phrases on a stationary camera.

This video is garbage.

I'm not an electrical engineer, but the video just throws some buzzwords again and again, no content. Sorry, it is like the entire thing is fictional, made only for the views (I hope not)

I have been doing this for years. Many years. Perhaps I should also say that I am not all that special of a power electronics engineer. This is typical stuff.

ChatGPT, write me a few paragraphs on how DC to DC conversion improves efficiency….

When trying to fool people using AI fails!!!

Google this... Over 98% Efficiency SiC-MOSFET based Four-Phase Interleaved Bidirectional DC-DC Converter Featuring Wide-Range Voltage Ratio

RUclips does RUclips things... I don't know why this video was recommended for me. Basically this is a PR advertisement for some lab at a university. It's great that they do what they do - I just received my masters degree with a side specialization of a power electronics lab just like this, doing incremental research on tuning well known designs. But there is nothing new here, no breakthrough... Please do not spam us with useless ads.

So many words to say nothing.

The weapon industry is gonna go crazy with this

I appreciate your upbeat character and warm spirit that raises my intellect to new heights and you do so with a high efficiency with a liberal and advance master of the best thesaurus. You do have some great speaking skills but need to dive in deep concerning the details of DC to DC converters.

i learnt nothing

A whole lot of buzzwords and techno jargon, but zero details or explanations. I give the video a solid 2/10

No technical details? No test results? No power curves?

Fluff. You didn't even say how much power the device - or device design - could handle.

I don't think this is particularly new though. It looks like its just a synchronous buck converter. A good one, sure, but... still just a synchronous buck converter. Hard to tell since you didn't describe the actual circuit design. Note that the high-efficiency path is only going to be in one direction... its hard to get high efficiencies with a boost converter. You only really get them with buck converters. Also, large voltage differentials reduce the efficiency. DC-to-DC buck conversion is an inherently efficient process. In fact, if you look at run-of-the-mill solar charge controllers today such as Victron, those operate at efficiencies of 98% to 99% right now. And they have huge input voltage ranges. Current-day string inverters and micro-inverters such as enphase also achieve roughly 98% to 99% efficiency converting DC to grid-tied AC. That works because grid-tied micro-inverters are current-regulated devices rather than voltage-regulated devices. In fact, charge controllers are too. It is easier to tune the magnetic components (such as inductors) in a current-regulated design, and a lower switching frequency can be used as well... which all translates to very high efficiencies. Current-regulated designs do have some warts... the main one is relatively poor voltage regulation. That is, the output voltage or waveform can jerk around a bit as the load changes. But the cool thing about it is that you don't really care if the output does this in a grid-tied or charge-controller use-case because they are connected to the grid or to a battery, both of which are extremely low-impedance black boxes. Since the impedence is practically zero the voltage can't be moved all that much and it winds up just being a matter of current flow. -Matt

So it’s basically more directional instead of waves of hit or miss ?

Need to say how is the one that discovered or invented this material Adele Djellouli from ? !!!!

Your logo on top of the "chart" makes it worthless.

My take, at least with Tesla compared to an average ICE would be driving 2.5 hours in both before needing to stop for gas, bathroom, snack. ICE that stop takes about 15 minutes. Tesla takes about 30 minutes. So, each 2.5 drive chunk adds 15 minutes. But it smells way less like gas fumes each stop. And if YOU are driving, and safely, you’ll want to also check your phone and stuff. Which you can just sit and watch an episode of something on the car screen and then continue driving. You’ll arrive later but probably more mentally with it. And yea, eventually you’ll be charging faster than gas fill up and able to drive longer range, and it’ll be mostly autonomous driving. And if you want to go greener with fuel, it’s impossible with gas, and even if a portion of EV is with green then it is better than fuel, and with the growing amount of fuel it’ll be even more and more green energy as time goes on.

It takes 40 hours in a cybertruck, going from florida to california, as proven by out of spec motoring.

The EV crash has already occurred and manufacturers around the world are now trying to spin their way out of this giant hole that governments pushed them in to. The end of the whole green scam has already begun. Renewables (with the exception of hydro) are quite simply useless at scale. There have now been enough people to experience the 'green dream' to realise that it is actually a nightmare. Solar and wind factories taking up valuable farming land with hideous transmission lines criss crossing through national forests was not what was sold to us.

EV’s are inevitable. Charger locations increasing and batteries will get better. The model T had a 20hp motor, top speed of about 40mph and range of about 225 miles on a full tank. Gas stations were few and far between so many people preferred their horses, but today I can’t find a horse on the roads. Like the horse, EV’s will eventually replace most gas guzzlers.

Duuuude, silicon carbide is SiC!

Sand batteries become more efficient at scale due to the Surface Area vs. Volume physical properties. Volume increases faster than Surface Area giving you more storage capacity with less loss. Would be great to boost/augment the efficiency of existing thermal powerplants to also utilize the excess heat generated.

Okay, but why don't companies develop these types of energy storage systems for use by single-family homes with installed solar? No one every develops technology that has immediate cost efficiencies, and therefore technologies like this always end up being the subject of RUclips videos and popular science magazine articles. As you say, the battery is just sand, and the basic heating and insulating technology, integrated with a home solar controller, does not seem to be rocket science. Yet no one every makes a product. Frustrating....
