and we will not surrender until free energy will be enabled all over the world, to power planes, cars, ships and trains.
Free energy will help the poor to become independent of needing expensive fuels.
So all in all Free energy will bring far more peace to the world than any other invention has already brought to the world.

Yes, he made the CLAIM but did not back it up with proper measurement or analysis.

  I see Tinman's comments are still there,bit more diplomacy required MileHigh.

Yes, he made the CLAIM but did not back it up with proper measurement or analysis.


What measurement and analysys he did make was backed up by the fact that he disregarded the excess energy still stored in that hybrid capacitor. And even given that his numbers still come out on top. Now lets mention the cost to produce each. Now we have a problem Huston. pound for pound his setup will always win because his methods of production vastly outweigh the costs of lithium ion. And that is a winner in my mind. Not only that is the benefit that his design as shown is not poisonous to us or the environment.... Can lithium Ion claim that?


And by the way in all courts that I have known it isn't the burden of proof on the claimant it is the burden of proof on the accuser. You make a claim, "he is misleading people". Then prove it or get off the soapbox. Watch his other videos about producing all the components and try it yourself. Do the scientific analysis as accurately as you want and quit this crap. You prove he is misleading people! Not by looking at a video meant to inspire experimentation but actually build the thing. Otherwise he has no intention of helping trolls. And that is exactly what I see here.. MH trolling him not from doing it but sitting back and spouting BS about this and that.


The whole aim for him is to inspire others to do, not talk crap behind his back. If there is no valid concept here for you then move on and let it go. Is it wrong of him to inspire others to have fun while experimenting and doing the experiments? No way.. is it wrong for you and others to mock him and call him names when hes has shown what he has done? YES! It's no wonder he hasn't come to these boards. Not because he doesn't believe in these forums and technologies but because there is always a few out there that take all the fun out of experimenting and finding something of interest to inspire others to get that same excitement out of it. He wants others to experiment and yes if it comes down to it he will test it scientifically when it is appropriate ie like selling it to a manufacturer like Tesla or other companies. You and the others are not funding his work. You have nothing invested other then watching a rough video to present rough calculations to see how it stacks up to the current technology. And yet you profess he is misleading people. PROVE IT! The burden is on you not him.


If he completed the test it would have made the calculation more in his favor yet you guys don't understand that do you? Even with that and even if he missed the mark by 50 percent or even 70 it still would have been better then the lithium ion battery with way less material used and all of the safety the materials he uses provides.

  Lets look at a similar device the lithium ion capacitor:


"A lithium-ion capacitor is a hybrid electrochemical energy storage device which combines the intercalation mechanism of a lithium ion battery with the cathode of an electric double-layer capacitor (EDLC). The packaged energy density of an LIC is approximately 20 Wh/kg generally four times higher than an EDLC and five times lower than a lithium ion battery. The power density however has been shown to match that of EDLCs able to completely discharge in seconds.[1] The negative electrode (cathode) often employs activated carbon material at which charges are stored in an electric double layer that is developed at the interface between the carbon and the electrolyte.


The positive electrode (anode) was originally made with lithium titanate oxide, but is now more commonly made with graphitic carbon material to maximize energy density. The graphitic electrode potential initially at -0.1 Volts versus SHE (standard hydrogen electrode) is lowered further to -2.8V by the intercalation of lithium ions. This process step is referred to as doping and often takes place in the device between the anode and a sacrificial lithium electrode. The pre-doping process is critical to the device functioning as it can significantly affect the development of the Solid Electrolyte Interphase layer. Doping the anode lowers the anode potential and leads to a higher output voltage of the capacitor. Typically, output voltages for LICs are in the range of 3.8–4.0 V but are limited to a lower voltage of 1.8-2.2Volts. If the voltage is brought any lower lithium ions will deintercalate more rapidly than they can be restored during normal use. Like EDLCs, LIC voltages vary linearly adding to complications integrating them into systems which have power electronics that expect the more stable voltage of batteries. As a consequence, LICs have a high energy density, which varies with the square of the voltage. The capacitance of the anode is several orders of magnitude larger than that of the cathode. As a result, the change of the anode potential during charge and discharge is much smaller than the change in the cathode potential.


The electrolyte used in an LIC is a lithium-ion salt solution that can be combined with other organic components and is generally identical to that used in lithium ion batteries.


A separator prevents direct electrical contact between anode and cathode."


"Batteries, EDLC and LICs all have their own properties, which make them suitable for specific applications. The lithium-ion capacitors have a higher power density as compared to batteries, and LIC's are safer in use than LIBs, in which thermal runaway reactions may occur. Compared to the electric double-layer capacitor (EDLC), the LIC has a higher output voltage. They have similar power densities, but energy density of an LIC is much higher.


The Ragone plot (figure 1), shows that the lithium-ion capacitor combines the high energy of LIBs with the high power density of EDLC's.


Cycle life performance of LICs is much better than batteries and is similar to EDLCs."


Omg what did it say?


"""""""""""""The lithium-ion capacitors have a higher power density as compared to batteries"""""""""""""""""

Omg the sky is falling....

So maybe he is onto something without the use of lithium and lithium ions for current boosting. Just maybe he has a novel idea that worked. And worked way better then using toxic chemicals and exotic metals.

What he did say is that for a given amount of material used he could store more in his hybrid then a lithium ion battery of more material. Pound for pound he is exactly right. Even with the rudimentary analysis he has done he shows this and given the fact that he did not discharge his hybrid fully in that video I would say that shows the errors were fully acknowledged to be his advantage in this case. You seem to focus only on what you want to see and don't think anything about the fact that the test was not fully complete when he cut off the test early due to time restraints.

No, in fact RMS has not proven anything because his measurement is a total fail.  He is just measuring current flow without accounting for the voltage associated with that current flow.

Pound for pound he has proven nothing and his conclusions are exactly wrong.

I will repeat to you that a 12-year-old that is very astute and is interested in batteries and electronics would not make that gross error.  Yet you have a grown man making a ridiculous mistake in that clip and the mistake is indefensible.  So you are just wasting your time in the face of incontrovertible evidence that his measurements are dead wrong.

You simply cannot make a mistake like that.  You can't in good conscience present junk data.  Or can you?  Look at all the YouTube comments congratulating him and how nobody here spotted the problem.

At this point you just want to be argumentative to push your own personal agenda.  "Those nasty people that insist you read the data on your multimeters and analyze it properly."  Yes, you have to read the data on your multimeters and analyze it properly with no exceptions at all.  Yes, you have to account for the voltage when you are making an equivalent ampere-hour measurement with no exceptions at all.

You are making "Bizarro World" arguments but the problem is this is not a Superman comic fantasy, this is real life.  You have nothing Jbignes5, nothing.
