Why can't we just set these up so that stronger animals than us turn them? Horses, cattle, dogs, etc...set up a dog run, put some harnesses on some big mastiffs, and let them run and have fun all day long.
How about solar photovoltaic electric energy used to produce HHO (low amps + super high volts) and as hydrogen is produced, have a generator produce electricity form the hydrogen to recharge multiple batteries for home use and actually sell the excess energy to the electric company? That should be happening now. Oil companies might have killed Stan Meyer but they can't kill us all.
DAN, could you please do a video on HHO as a usable power resource as this is a great video and i also hear that this a great way to power your car and help the environment at the same time... i hear that this type of system (hho) is also something that can improve your fuel economy. BTW great video and say hi to the wife for me :D
Put peddles on the generator axel instead. Less work. I want to reconnect the HHO as heat energy, turning a turbine to help peddle, reducing the work to make the HHO to create the heat energy to run the turbine, and so on...
I wonder how much crabon you produced doing this. I bet you produced more greenhouse gas than a nuclear plant or even burning coal would have to produce the same amount of power
@tahoeskiier The point was to generate HHO not electricity. Electricity is used to generate the HHO. The electricity comes from the pedaling. What he is doing is an electrolysis of water. Water doesn't contain carbon. So he wouldn't have been producing any CO2.
I hope you're not using a stainless steel electrode... It puts extremely poisonous chromium into solution, which can then be absorbed through your hands, get into groundwater, etc.
Really, the only safe and non-oxidizing common electrodes for this are platinum or pure carbon. Pure carbon is my choice, as platinum is over budget ;)
You might also consider using hydrogen peroxide in pure water to give conductivity, as it ionically dissolves into water and consists only of hydrogen and oxygen.
Excellent HHO production demo. This is what HHO skeptics trying to say about HHO boosters ( IT DOESN'T WORK ) because it takes more energy to produce HHO than the energy it can put back. There's the PROOF, Dan Rojas can hardly pedal the bike and almost no HHO is being produce, but if the HHO generator will be turned off, of course he would be able to pedal the bike again. So maybe the NAYSAYERS were right this time, until one HHO sucker can modify a real working HHO BOOSTER.
wow at first it didnt sound like it but more into this video the guy sounds alot like zack galifinakis.... dude can you say HOW DARE YOU SHE'S A NICE LADY!!!!!!!! HAHAHA
Why the heck aren't we producing hydrogen using solar and wind? I hear that compressing it is illegal, why? it's a good way to store energy which is the main problem with wind and solar power.
Great video and fascinating experiment that proves just how hard it is to get electrons to move along a conductor (to generate electricity). I realise the gearbox ratios will make it more difficult to turn in your set-up but it shows that in nature - there's no such thing as a free lunch. It takes effort to spin a conductor in a magnetic field... in the words of Homer Simpson - ''Damn stupid Lenz's Law''
I love your bike mount, no welding and much better then the others Ive seen! Ill have to build me one. Have you hand wrapped a pan cake generator head? I think it might be ideal for this set up. My dad had one and it looked like something you could duplicate. Unfortunately he sent it down to my cousin so i cant examine it and try to duplicate it any more.
when using stainless plates, be very careful about what you are doing with the waist water, as the hexavalent chromium can leach out of the stainless. that shit is nasty very very nasty
I think one thing this shows is how much energy is needed to split water. Lots of people think that hydrogen fuel cells are going to be some kind of free energy solution. "Hydrogen is the most common element in the universe!"
Problem is, most of it here on earth is stuck to oxygen or carbon.
This is cool. If you could rig the bike with more gear settings so it's easier to ride, you could generate electricity while getting your daily exercise.
I am sorry, I don't really get the point to the HHO generator...
At first, you showed the pure output of the generator, and reached 8.9 amps just at a very low rpm with the hand. Then you connected the HHO tank, and achieved 10.2 amps, at many times the rpm - what was the purpose of the tank in this case?
you want as close as possible 2 volts between 2 plates, anything more heats the water. insert as many neutral plates as needed between the active plates to divide your source voltage to end up with 2 volts between adjoining plates. with this design however (meshed plates) you get tons of current leakage anyway....
now you want to plot watts over time. Then, try to calculate the force required to turn the pedals, and then you can calculate the efficiency of this process. From there, playing with different densities of potassium hydroxide may give you a max efficiency. In fact, via newton's method (in mulitple dimensions) you could numerically find the best combinations of MANY factors to raise efficiency of joules in vs. joules out. More math, dan! MORE MATH!
why we need a bike to power it dont we have wind or sun? ok for fitnesclubs that could be realy cool then you woulnd not have to pay for the membership ... hehe thats it cool a fitnesspowerplantclub ^^ .... ok not perfect but a idea ;).
I think this is awful way to power things. Human powered devices are stupid for practical domestic use cuz electricity and gas are still super affordable and very widely easy to access but it dependeds who you are and where you are. All I am saying is this is not my cup of tea.
@cgw34743474 No! I would find a better way like candle lighting or I would use solar for charing my batteries. Worst thing when being poor is being hungery not powerless. I think this human powering stuff is backwards thinking. If you fill your mind with engineering theory and watch nature do her thing you can almost invent your way out of a bad situtation. Educate your self and don't wait for it to arrive at best buy or walmart. Best things in life are free from the environment around us.
Hmm connecting that to a small bike motor would make fucking epic bike for example! If you could do that and sell it? That would be fucking amazing! I mean you first use your pedals to charge batteries... Thats a workout for ya! Then you power up your Electric Engine and tada!
How about using a solar panel to make the power to generate the hydrogen and use that to power stuff? would that work or would it be better just to use the solar power as it is? - I mean use the solar in a setup like you had to make the hydrogen gas then burn the gas to make an even greater amount of power by driving a steam turbine or similar? Or does that sound stupid?
Forgive me if I sound a bit dumb, but I thought that the more IONS there were in the water (electrolyte) the EASIER it would be for the current to flow between the plates AND for more electrolysis to occur - kind of by if anything, lowering the resistance as well.
You should ride that bike more Dan... all that panting makes every one excited.
@callmeshane303.Yes it's the current that controls the rate of electrolysis.
Think GPS has fixed voltage, and is changing current.
Reducing the resistance of the cell allows more current, but the voltage can never be dropped below the electrode potential needed (for water is about 1.4V).AS P=V*I useful power generating Oxy-hydrogen in watts is 1.4*current. Lower resistance of current path through the water, means better efficiency, but voltage has to be reduced to keep power constant.
You were losing a lot of power transfer with your bike set up. Essentially your seat looks like it needs to be moved back and raised so you get all of the power from your leg extension. Even so, 255 watts is a lot of work. Gearing will not reduce the work needed to produce the 255 watts but would allow a higher rpm which would make it more aerobic rather than anaerobic. 160-180 Watts over 30-45 minutes is very feasible.
255 peak, humans dont pedal much more that if anything! usually about 100w cont. thats why some areas restrict electric pedal cycles to 200/250w motors max. - I do like your gearbox on that motor, was looking at a motor just like that but without gearbox, was 36v 500w, was going to bike it to help get the shopping home, a gearbox on it like that may help make the batterys last longer
Tried square rods, mounted in an a*b grid vertically with spacers on both sides near each end?
It significantly increases the effective electrode area and if you're running the cell with no neutral plates all that's needed is for a*b to be even and alternate the polarity supplied to the rods. Found with a 1cm square rods, very small spacers a 4 by 4 cell the cells resistance was low to pull a half decent current on 5V and with straight tap water. Other patterns will allow for neutral rods.
here is a good suggestion for you . I see thgst yoiu have trouble at the week point of the peddling so if you add a flywheel to the mix it will smooth out the rmp's . just add a heavier tire to the back of the frame. and i would sallso suggest that you use potassiun nitrate instead of that caustic stuff. Safety first my friend
just think of it as your training for Tour de France. by the way how would you collect the hydrogen? in this video you are just losing all of your effort into the air.
I'm not understanding the point of this video either, wouldn't it be cheaper to connect the bike to a grid tie inverter or a deep cycle battery? If you make HHO, you are losing 189 of those precious 225 watts as heat. Sorry, I'm with AverageJoe8686, snowman3514, DJRockinRob and ryobie1 on this one.
Don't feel compelled to post videos every week, as an experimentalist, realize how difficult it is to come up with a science video on a regular basis. Focus on quality, not quantity.
i think you should put up more video of that hydrogen generater think it would be more interesting of a video than a guy that cant pedal a bike to try to get his point across, and im sure its hard as hell to turn that motor, how well does it work of you put that thing on a battery charger?
@AverageJoe8686 Yes, that would be part of it. The other part is to demonstrate that it IS possible and to give someone a kick in the brain cell to try something else with his basic idea. What I like about Dan is that he is NOT AFRAID TO TRY SOMETHING NEW even though it may not be CURRENTLY practical or useful. Someone else may see it though and go, "WOO HOO, that is the info I needed for MY idea!"
I played with one sun panel recently and had an irresistible urge to say "I'm your host Dan Rohas, thanks for watching and enjoy our videos" when I was done xD
Ideally you want the voltage to be about 1.23V per electrolysis cell. (run in series to increase the resistance). Additional voltage is needed to overcome the electrolyte's resistance.Resistance increase with spacing between electrodes, and decreased with increasing conductivity of the electrolyte. The power lost as heat= (V-1.23)^2 /R
@GREENPOWERSCIENCE, as you well know, the conversion losses in your generator drive, in particular (electrical losses, but mostly: the spur gearing of that gear motor, that is not designed for driving the motor, but driving the output shaft) are huge. I bet you were inputting many hundreds of Watts momentarily, but most were lost in the gear motor. It's an interesting demo, but, the old story holds, that most such generating schemes are not optimal. They need to be custom made, direct drive.
@GREENPOWERSCIENCE Dan you are absolutely right, it is in fact a dead short meaning it would be much more harder for pedaling or you might not be able to pedal it at all.
Ever try to use your solar panels to generate HHO for your car so your generator will not be loading your engine? As I understand it the gas is difficult to store and if you are to use it you would be better served using it as produced. I ahve seen people use HHO generated from the alternator but that loads your engine wears out your alternartor with solar panels I bet you could produce enough HHO to assist combustion inyour engine providing benefit that way?
Interesting: Just saying - if you could pedal enough to do 20Kmh or 12mph on flat ground - no wind, then switch that output over to a generator, then run it into a HH-O generator; then feed those gases back into a fuel cell, to feed that power back into a efficient DC motor - to drive you on your bicycle, on the flat ground ---- I wonder how fast you would go then?
@icovada "Oh fuck really" - thanks for the insight.
So can you show us the maths in terms of proportionally stepped losses at each change of state based upon using reasonable "store bought" items and their efficiency?
I just like to "understand" the whole process in an objective way, instead of a subjective way.
@callmeshane303 : I'd actually like to see what the average energy value of food is, then calculate in all of the losses from the farm, to the consumer, to the cooking and digestion, then to the generator, to the HH-O unit, to a fuel cell, to a battery, then back to an electrical motor - based upon gross national averages; Which I think overall is the general principle of renewable energy sources.
@callmeshane303 ----Is it really 1000 units of energy at the well head and 500 units of the sun, that after all the transport, fertiliser, conversion losses, etc., that makes it back into your bicycle back wheel as 5 units of energy?
I'd like to actually sit down and work it all out to get an accurate picture of the total energy cycle.
Any takers from the national bureau of statistics etc.?
@callmeshane303 This would imply several variables, depending on what kind of devices you buy etc, but if you knew the laws of thermodynamics you wouldn't have even asked that
Hey dan, what would you think about putting some sort of flywheel on it to help maintain your momentum? or heck, maybe a few shifts of gear perhaps? I'm wondering about that myself; for instance, if you were to leave the back well on it and add an extra gear to the opposite side of where the bike's default gears are at a very tight ratio, and attach that chain the motor at a slightly wider ratio.. that way you can get its inertia built up, and keep it going at a high speed. Pace is important.
Hmm dont think i get it ... you used a pedal powered generator to provide electricity for electrolosys that produces hydrogen? Why? would you save the h2? how? isnt there a solar pannel(s) you could use to power a DC motor that could replace you on the bike? I get that it was hard, but at that level of difficulty vs return doesnt it file in the "not worth it" category?
@DJRockinRob better to attach a solar panel directly to the electrolysis tank, then collect the hydrogen. Hydrogen stores energy FAR more efficiently than batteries; it's just that it's... extremely flammable, and needs to be compacted at a rather high pressure in order to store any amount sufficient for storage. Once it's stored, though, and as long as you're not stupid with it (the same can be said for most dangerous things) then you can tap that energy for fuel cells OR internal combustion!
@DJRockinRob Under our current LOW COST energy society it may well be "not worth it". At some point in the future LOW COST energy will go away and then this will be a GREAT IDEA!
plates are better than wires, you got too much current leakage. also you should use 10 guage wire because you could be drawing too much amperage, and the wires will get hot
@ryobie1 at this point, it seems more viable than doing exercise for NO material gain at all. Electricity is practically a universal currency even in the third world; every civilization that calls itself a civilization needs electricity at some point even if only for their cell phones. Generate power while exercising and it can ice the proverbial cake of getting into better shape very effectively.
I'm just a diesel mechanic but I'll make a suggestion anyway. If a plate that size requires such a huge generator load, why not chop it into something 1/4 the size. That might be something you can maintain for a while. Your legs have a power band (just like a diesel engine) where maximum power is produced at a certain RPM. For a cummins diesel engine it's about 1500 to 1800 rpm but with your legs it's about 60 rpm. Trim the plates down until you can reach 60rpm with a comfortable pedal load.
Dan, there's no such thing as a neutral plate in an open electrolyte bath with screen material for "plates". To your generator it still looks like a dead short. Take a look at my new "Batt-Cell" series. With straight DC I have hit 5.92 ml/min/watt efficiency so far. You can also check my FAQ at alt-nrg*org.
Try making Sahubergers generator - it works on compressing the water. the compression happens by using centrifugal force and narrowing tubes at the exit. This force is spinning the tubes and sucking up more water.
At 200 watts I figure you can light up about 4 bedrooms with 25 watt CFLs.
And you said it was like riding uphill in 10th gear. Ha! Makes me have more respect for all the work electricity does for us in a day... Excuse me now, I'm going to go turn off some lights.
one would think you would have put gears on here for finding out how to generate hho by human you'd figure out gears would help you even more...not rippin' on you just observing
I always had an idea that local Gyms could have this kind of tech so that when you excercised you could generate power and send it back to the power company,..paying for your membership (if you worked out enough) ...perhaps if you generated enough ..you could even get payed haha..
Hey..Cool generator..Thats showing the work to get the energy,store it in a battery and turn the same motor..put the wheels on and ,,,this is so cool,

Tried square rods, mounted in an a*b grid vertically with spacers on both sides near each end?
It significantly increases the effective electrode area and if you're running the cell with no neutral plates all that's needed is for a*b to be even and alternate the polarity supplied to the rods. Found with a 1cm square rods, very small spacers a 4 by 4 cell the cells resistance was low to pull a half decent current on 5V and with straight tap water. Other patterns will allow for neutral rods.

i think that a flywheel and a lower gear ratio and shifting would be more beneficial. it would get rid of the pulsing effect of your pedaling.

here is a good suggestion for you . I see thgst yoiu have trouble at the week point of the peddling so if you add a flywheel to the mix it will smooth out the rmp's . just add a heavier tire to the back of the frame. and i would sallso suggest that you use potassiun nitrate instead of that caustic stuff.

I'm not understanding the point of this video either, wouldn't it be cheaper to connect the bike to a grid tie inverter or a deep cycle battery? If you make HHO, you are losing 189 of those precious 225 watts as heat. Sorry, I'm with AverageJoe8686, snowman3514, DJRockinRob and ryobie1 on this one.

Any ideas how to keep the gases from mixing?
--
Ideally you want the voltage to be about 1.23V per electrolysis cell. (run in series to increase the resistance). Additional voltage is needed to overcome the electrolyte's resistance.Resistance increase with spacing between electrodes, and decreased with increasing conductivity of the electrolyte. The power lost as heat= (V-1.23)^2 /R

migxp1 1 year ago
@GREENPOWERSCIENCE, as you well know, the conversion losses in your generator drive, in particular (electrical losses, but mostly: the spur gearing of that gear motor, that is not designed for driving the motor, but driving the output shaft) are huge. I bet you were inputting many hundreds of Watts momentarily, but most were lost in the gear motor. It's an interesting demo, but, the old story holds, that most such generating schemes are not optimal. They need to be custom made, direct drive.

Ever try to use your solar panels to generate HHO for your car so your generator will not be loading your engine? As I understand it the gas is difficult to store and if you are to use it you would be better served using it as produced. I ahve seen people use HHO generated from the alternator but that loads your engine wears out your alternartor with solar panels I bet you could produce enough HHO to assist combustion inyour engine providing benefit that way?
cdltpx 1 year ago
Interesting: Just saying - if you could pedal enough to do 20Kmh or 12mph on flat ground - no wind, then switch that output over to a generator, then run it into a HH-O generator; then feed those gases back into a fuel cell, to feed that power back into a efficient DC motor - to drive you on your bicycle, on the flat ground ---- I wonder how fast you would go then?

@icovada "Oh fuck really" - thanks for the insight.
So can you show us the maths in terms of proportionally stepped losses at each change of state based upon using reasonable "store bought" items and their efficiency?
I just like to "understand" the whole process in an objective way, instead of a subjective way.
callmeshane303 1 year ago
@callmeshane303 : I'd actually like to see what the average energy value of food is, then calculate in all of the losses from the farm, to the consumer, to the cooking and digestion, then to the generator, to the HH-O unit, to a fuel cell, to a battery, then back to an electrical motor - based upon gross national averages; Which I think overall is the general principle of renewable energy sources.
callmeshane303 1 year ago
@callmeshane303 ----Is it really 1000 units of energy at the well head and 500 units of the sun, that after all the transport, fertiliser, conversion losses, etc., that makes it back into your bicycle back wheel as 5 units of energy?
I'd like to actually sit down and work it all out to get an accurate picture of the total energy cycle.
Any takers from the national bureau of statistics etc.?

snowman3514 1 year ago
Hey dan, what would you think about putting some sort of flywheel on it to help maintain your momentum? or heck, maybe a few shifts of gear perhaps? I'm wondering about that myself; for instance, if you were to leave the back well on it and add an extra gear to the opposite side of where the bike's default gears are at a very tight ratio, and attach that chain the motor at a slightly wider ratio.. that way you can get its inertia built up, and keep it going at a high speed. Pace is important.
Stonehawk 1 year ago
Hmm dont think i get it ... you used a pedal powered generator to provide electricity for electrolosys that produces hydrogen? Why? would you save the h2? how? isnt there a solar pannel(s) you could use to power a DC motor that could replace you on the bike? I get that it was hard, but at that level of difficulty vs return doesnt it file in the "not worth it" category?
DJRockinRob 1 year ago
@DJRockinRob better to attach a solar panel directly to the electrolysis tank, then collect the hydrogen. Hydrogen stores energy FAR more efficiently than batteries; it's just that it's... extremely flammable, and needs to be compacted at a rather high pressure in order to store any amount sufficient for storage. Once it's stored, though, and as long as you're not stupid with it (the same can be said for most dangerous things) then you can tap that energy for fuel cells OR internal combustion!

@ryobie1 at this point, it seems more viable than doing exercise for NO material gain at all. Electricity is practically a universal currency even in the third world; every civilization that calls itself a civilization needs electricity at some point even if only for their cell phones. Generate power while exercising and it can ice the proverbial cake of getting into better shape very effectively.
Stonehawk 1 year ago
I'm just a diesel mechanic but I'll make a suggestion anyway. If a plate that size requires such a huge generator load, why not chop it into something 1/4 the size. That might be something you can maintain for a while. Your legs have a power band (just like a diesel engine) where maximum power is produced at a certain RPM. For a cummins diesel engine it's about 1500 to 1800 rpm but with your legs it's about 60 rpm. Trim the plates down until you can reach 60rpm with a comfortable pedal load.

2. If you do that, you'll get the maximum hydrogen yield per calorie burned (if I understand the problem).

Dan, there's no such thing as a neutral plate in an open electrolyte bath with screen material for "plates". To your generator it still looks like a dead short. Take a look at my new "Batt-Cell" series. With straight DC I have hit 5.92 ml/min/watt efficiency so far. You can also check my FAQ at alt-nrg*org.
