Finally people are listening to physicists instead of garage inventors and pitchmen for vast scale solutions. I wrote a paper on pumped hydro in 1980 for my physics class. The problem is it only works where you have the terrain. The super low resistant flywheel is very promising for the traditional grid retrofit. The non day compressor/swamp cooler ( freeze by compression at night, thaw by day) for an industrial scale is beautiful. the best human solutions always use the simplest Newtonian concepts. Yes these physical concepts are old, but it is how they are applied that make them genius or bullocks. All normal energy is converting potential to kinetic energy and then constantly transforming it, sometimes to a more useful potential energy. Every time you transform, you lose some portion to inefficiency/waste, and typically that becomes pollution.
Flywheel dude. It needs to be 100 times bigger like the size of a Ferris wheel. Made of cast iron and spun up by geothermal. Always in motion slower rpm and provides baseline energy.
I've been thinking about this kind of battery last year and after a great effort until I got to the result،I rejoiced and said this is a new invention would change the world, but I discovered it already exists. The same idea and mechanism of work that I reached without having any idea before
This is very smart I mean the ice battery Flywheels aren't that great except to sustain a load long enough for the actual backup power to kick in, unless...as you see here, it's VERY BIG and VERY HEAVY
I think the point was to show how we can create batteries out of all sorts of things, which are so much cheaper than typical batteries that it might be worth it to use them instead, despite any decrease in efficiency.
What is the difference between cheap electricity and expensive electricity? How long does it take to charge up or store momentum energy in the flywheel? Seems like they're forgetting to mention something?
Certain regions in the US have smart meters, and you get charged more per kWh during peak hours (7-9 am and 5-9 pm), which is done to discourage people from overloading the power grid. As for how long flywheels take to charge, that's sort of a loaded question. That's like asking how long it takes a battery to charge--are we talking about the battery in an iPhone (30 minutes), or the battery in a Tesla (14 hours)? If the shaft can take a lot of torque, you could charge it in a few seconds! But my guess is that they're designed to reach a full charge over 6 hours or so.
A quick calculation gave me about 140 MJ of energy per flywheel. That is assuming a cylinder with radius of 0.6 metres, mass of 2.25 metric tons and spun at a rate of 8000 rpm. That energy translates into about 39 kW-hours of energy storage. Enough energy to power two households for about a day. I believe they designed these flywheels to extract 10 kW of continuous power out of them for four hours so it would be safe to think their design capacity can be 40 kW-hours.
@@Spacekriek That's cool, but hard to imagine that installed in a home to replace batteries. If batteries were to get cheap enough for large scale residential use, this flywheel seems far more dangerous. Also I imagine just the parts alone cost more than batteries today. Hey, you were close (32 not 39) amberkinetics.com/product/
@@matthewfuller9760 I've been reading up a bit as far as the cost is concerned (energystoragereport.info/amber-kinetics-flywheel-sales-next-year/). In 2017 they had the price at $325 per kWh capacity. That is already a very competitive price when you compare the expected life of the flywheel system to a normal gel type battery (30 years vs about 6-7 for the gel). With the technology and economies of scale being as they are I do believe they will become much cheaper as the demand grows at the domestic level. As far as safety is concerned, I see they install their flywheels just below ground level. I can only imagine that the developing team either had some spectacular incidents where they experienced catastrophic failure or they are just taking no chances. Worse comes to worst, if that happened at your house you would probably just hear a very loud thud and the floor would shake a bit. At least the damage would be absorbed by the earth beneath you. Come to think of it, there is always some kind of warning sign that would come up just before that happens. If I were the engineer working on this system I would have some kind of braking mechanism kick in just before things really explode.

I really hate that they dumb it down for people that don't understand kWh. 4 hours is a nonsensical measurement. In theory if you applied enough electrical load on it, you could almost immediately bring it to a dead hault. Alternatively, if there is minimal to no load on it, it could spin for days or weeks. It's like regenerative braking in electric vehicle.
@@Spacekriek I'm not a 100% and could be wrong, but I'm quite sure your math is completely off. 39kWh isn't much. My flow heater has 24 kW max, and during a usual shower it's at 12kW iirc. My oven uses a shtload too, with the oven heating and two plates on it'll already cut power to further plates, I assume because it's at it's 21kW max rating then. Let's assume 10kW for both. So, cooking diner for thirty minutes = up to 5kWh, three people on average showering for 10 minutes each per household = 5kWh. One household, not stinking and not hungry = 10kWh. With all the other utilities I'd rather say it's 2-3 households with three persons each. Even if I'm way off there's no way that's enough for even five average households nowadays. Edit without edit: Just looked it up, the average electricity consumption in the US is just shy of 30kWh per day. So, yeah... Edit: I'm a rtrd. Somehow I read two thousand households, no idea why...
@@heinzhaupthaar5590 Please see my reply on Rikkerd Harderz's comment a bit lower. My calculations were purely based upon the physical properties of the flywheel (39 kWh compared to 32 kWh according to the mentioned website). I think I managed to come pretty close to the truth. You might well end up with 32 kWh after considering the input and output losses.
New to this stuff, I have two questions: 1st: The Ice Cooler at 3:20, does it blow out humidity such as a so called Bog Cooler? or is it dehumidified through the a.c. unit? 2nd: The 5000lb flywheel shown at 5:20, Could in theory, sense it's levitated by magnets, and in a vaccum, be spun my hand or a bicycle tire, producing much more energy than the little pedal bike generators I see everywhere? Thank you for your time if you answer, i appreciate it
As I understand it, the frozen a/c system simply takes advantage of the ice to cool the coils instead of a refrigerant, like Freon, running through a compressor to produce the cold coils. So it probably should not blow humidified air anymore than a typical air conditioner would. This is based on a VERY limited understanding of the system, so I could be way off. Be strong and courageous!
Huge Wind farms, solar plants, when exceeding demand during the day, sure - if they are in locations where molten salt systems are illogical due to cold climate, i see this as a good alternative. However the question is how much power does it take to get it to this 8000rpm and how many kwh does it generate afterwards. How much energy is lost is the question, 5-10-20%? as when converting to different form of energy you get losses anyways. depending on how much loss it is, it would be a good alternative, but it is to remember that you would need an Equal amount of capacity to store as the capacity to produce. so that at peak production, if demand is low, example wind farm, at night. It would need the ability to store all of the energy its producing. so that early morning the grid would have a high surplus stored
Nope, because you've still got peak loads, which spike ever higher with population and wealth, and storing excess electricity generated during low demand hours to use during peak demand could be cheaper and more efficient than building and maintaining extra power plants that only come online when peak loads have to be met. Whether the plant runs on natural gas, wind, solar, hydro, or even just a coal-rolling F350 on a giant hamster wheel for maximum liberal triggering, power storage would be cheaper, more efficient, and more reliable than running as many as 1/4 of US power plants, if the batteries are cheap and long-lasting enough. 30-40 years instead of the current 10-15 would more than do it. That last part is what the physicists are working on.
