The point about how disparate technologies can sometimes come together to create solutions reminds me of James Burke's excellent BBC series Connections. Thanks for yet another interesting video.
A sci-fi book from the early seventies called "The Mote in God's Eye" has it's main character as a scientist who specialises in "Nexialism", looking at the edges of sceince subjects. ie how disparate sciences can work together to produce new processes that are outside of the disciplines. This idea fascinated me as a teen.
Hope you are ok Robert. You are missed by us all.
Now add in the raindrop generator 🎉
spot on lol !
Seems to me that this could be used to clean the solar panels on probes, rovers and other devices that are sent to land on Mars where dust that accumulates over time can be safely removed to extend their mission lifespans. I guess this is provided that this doesn’t excessively add to a probe’s cost, weight and complexity. If NASA, ESA and other space agencies and companies aren’t working on this already, they probably should. Thanks for the great video.
tribo-negative. now i know what to call my goth metal covers band ;D
Thanks for sharing your knowledge and time.
I remember the PBS shows Rough Science and Connections. Both were favorites because they showed the possibilities of hands-on science applications.
Thanks Robert for your research here. I'm an inventor and your mention of "disparate" technologies providing solutions is really well illustrated
by a man named David Warren a scientist who was involved in the investigation of an airliner crash in 1953. He felt having a record of pilot's communications in the cockpit would assist in determining safety issues etc. that contributed to the crash. Near this time he had seen a product at a trade show. A small audio recorder. This inspired the development of reusable recording media and then a cockpit voice recorder that could survive a crash.
Brush cleaning if dust and solid debris is on the panels causes minute scratching on the surface producing light scatter which will eventually lead to significant lowering of power production.
I think it could be simpler to use compressed air to blow the dust away.
That'll cost energy. And perhaps it is abrasive
@@so_what_else_is_new yes but very little energy and the system can be very simple. On the other hand a high voltage system with a very weak generator might end up non functional after a rain. Also a compressed air system might work with no changes for snow.
Compressed air would be effective for about 100 mm from the nozzle. It won't be simple at all. You would need tens of nozzles per panel or have them on a moving dolly. Control system for the air would have to be quite complicated to keep enough pressure for the active nozzles to do anything etc.
Integrated way for repelling the dust with electricity would be way easier to manufacture. Those wind powered hv-generators might be a problem, but more centralized system could be plausible.
@@orionbetelgeuse1937 I agree. For rain or snow it won't work.
@@villehietala9677 having hv integrated in the panel doesn't seem such a good idea. Also making a hv connection from an external generator seems prone to leaks and in the end not working. I can't see what's so difficult in having a dolly travelling on a rail or two rails which blows the dust from an entire row of panels (if the panels are fitted in a common stand).
thanks ....Robert
Great way to see the world and life
The power of generalists! Thanks Rob, as always, putting things in perspective. An absolutely fascinating video, with a well made and much required point, thanks! 😊
"Jack of all trades, master of none, but sometimes a jack of all trades is better than a master of one"
Looks good for the larger particles but it seemed to leave a layer of dust behind and if it's getting sand blasted by nature then a wipe with a microfiber cloth probably isn't going to take that much off its lifespan.
He finds any excuse to be a jerk. Unfortunately, as intelligent as Rob is, he is also extremely prideful and foolish when it comes to his ego.
@@JSabh wtf are you even talking about? jerk? because he thinks wiping hard granular material from delicate fabricated electronics might be labour intensive and degrading to the infrastructure? Take your lithium carbonate, please.
Sage words sir
7 days a week?! Do you ever have a day off? Thanks for the video, I agree with your point. Every discovery tends to be more significant than is obvious at first.
A weird question, is the cold destruction method of expanded graphite production fake? The one where you start an autocatalytic reaction with a very strong oxidiser over GIC. Do you what is the intercalation compound and what is the oxidiser they add I wonder 👉🏻👈🏻.
Can you do a follow up video on how to upgrade an ordinary solar panel in a cheap DIY fashion with a tribo-electric magnetic repellent system?
You gloat all you want, Another great video, thank you
Oh, now that is interesting... Triboelectric Wind Power... hmm... great video.
Can we make electrostatic laminates for furniture tops to keep them dust free?
Seriously, thanks, the answers are all before us for those who listen, I appreciate you sharing and teaching sir.
Cheers
You could probably make use of a laminated electret. Teflon or PET or a number of other polymers can be cooled in a high voltage field to lock in a permanent electric dipole polarization. Hundreds of volts can be achieved at least, perhaps thousands with the right material.
Imagine if an electret was several thousand volts, a cold plasma double layer could form from exposure to UV from the Sun
The absolute example of synergy. 1+1 sometimes equals 3
Why not use compressed air to clean the panels. I use a leaf blower to clear snow of my panels in Sweden. ; )
I think in the places you'd most use this, you end up slowly sand blasting the panels and degrading the performance.
Every copier/ printer technician understands the triboelectric effect. (Or should 😉)
Just shows you need polymath not people being insular in their activities.
Pilkington Lotus glass ?
Sounds like whimshurst or Vandegraaff
A very practical invention that could save millions of pounds worldwide.
fit your solar ac on it's back
can you make a video explaining emp and emp war
It fries the electronics (semi-conductors made out of silicon and germanium). Electrical systems are almost unaffected (closed loops will experience increased voltage).
@@amvkarthik and here i thought it fried every electronics you may know but not many people
EMP arise from nuclear explosions. The charged particles moving along conductors generate high EM fields that can be so high wires actually burn.
It does not even have to be a closed loop to work. Look into the Carrington event to see how a solar flare (a large burst of charged particles) has the same effect.
@@amvkarthikI think it will melt copper wires as well
@@so_what_else_is_new no. If any wire melts and shorts the circuit then a respective switched gear must trip. Electrical engineering solved that problem. I've experimented that myself during my hostel days😂
They could use that on Mars rovers?
in dests where water is NoT a premium. on earth. scuff sciff
And one hail storm.......
A layer of UV polycarbonate and it's protected.
But how do you keep the triboelectric generator clean?😂
Just short to earth! - it will 'self' clean - (timing is key here )
Seems a little silly to couple the triboelectric wind to cleaning a solar panel. I mean, yes, if panel starts clean, wind moves dust, so wind power can be converted to dust removal. But dust will accumulate without wind, just from molecular motion. And wind may occur with no sun, so no benefit to cleaning a clean panel with no sun. Sure, there's energy lost for each conversion, but it's probably better to take the 5-15% loss of energy to capture potentially 500% more and store it. So I'm not objecting to either idea, just the coupling of capture and use, when decoupling is more beneficial, probably. But who knows, maybe there are certain climates where this coupling works, assuming climate and weather don't change... I try not to dismiss things out of hand, but I do reject certain applications or technologiea from time to time. I try to tuck it away and be open minded about the possibility or such a discarded idea -- or modification thereof -- might be useful in other applications.
sounds like it would be useful on Mars . . . because NASA won't spend the money to send some teeeager up there to wipe the dust off the rover solar panels.
If generating power is what we need to do, then why don't we focus on that instead of making fixes for solar panels?
The power of static electric is wasted on solar panels... At least for the kind of power needed for cities.
You're missing the point imo
Use of static electricity "to power cities" would have..... "Undesirable consequences"
.
Ever received a "static shock" from walking across a carpet, etc?....
Well, the charge has to come from somewhere.
If you're taking huge amounts from let's say the air, the result is a charge imbalance..... Giving the "potential" for Lightning.
@@rogerstarkey5390 how is static electricity different that electricity? Is there anywhere static electric is not?
@@so_what_else_is_new maybe...
@@rogerstarkey5390 not to mention that it's unpractical and virtually impossible. Think about power flow.
How about a solar heated stirling heat engine pushed by wind building rpm, then loaded above an rpm on a generator?
Good Easter fellow TnTers
happy easter to you too mate!
I belive this could be VERY usefull at the moon (and of cause other planets) where the dust is attaching to everything, due to electrostatics.
Perhaps this is what happened, when we several times had seen solarpanels been "cleaned" mysterically on Mars vehicles ?
Can we get a sequel, please?
Potentially......
