In 2014 while touring Wales as tourists from the States we happened to drive by the plant. On a lark we decided to stop and take the offered tour. It was an education. I had never realized that plants had to be built to manage surge demand. That visit started a process to learning more about back up systems for other plants in the USA and backup systems for homes. All of that started us down a road were two years later we bought our first EV, then recently a second. Now we’re trying to figure out how to generate solar energy and then store it for later use and for emergency backup.

Peter Najar It seems pretty easy really. 1) you have to have a backyard with a mountain 2) make sure there's a lake on top 3) excavate the mountain 4) build a huge waterpower station inside 5) Profit!
@Bluswede6 жыл бұрын
Peter Najar First you need to own a fair parcel of land at the top of a hill. (helps with wind generation) Then you put up a water tower with enough volume/head pressure to cover a few days without wind or sun. Then you install enough solar and wind to cover pumping the required volume of water up the water tower PLUS the 25% system losses WHILE running your home at normal usage. You'll need to determine the 'average Solar hours' available daily at your location as a part of this calculation, also. That should cover it...all mechanical storage versus a battery's electrochemical storage. Now balance the cost versus a large 'flow battery'. (there IS a Fully Charged episode on these) It won't be cheap, and you need to be in the right 'situation', but it's doable! There ARE residential-sized wind and water turbines out there, or you can build your own. (search KZbin for how-to videos, and do a lot of math!) Also...make sure you account for charging your EVs, AND be aware that you can also use them as storage batteries with the right software!

bren106 I think you've misunderstood what this station does. It's doesn't 'generate' power it stores power generated elsewhere and then re-distributes it. This is not renewable energy in the common meaning of the phrase, it's only renewable in the same way a battery is. In fact if you understood what was explained, this is 75% efficient so therefore it CONSUMES power. For every one of those 12,500 times it has been generating electricity, in the ratio of 3:4 it has also effectively consumed 16,666 'times'.

1 cubic metre of water has a mass of 1000kg, potential energy is given by m x g x h = 1000 x 9.81 x 1 = 9810 joules. If this energy is discharged in a second then that's equivalent to 9.81kw, I'm not sure where the guy gets 1kw from?

9.81kW for one second is 9.81/3600 = 0.0027 kWh to lift a ton of water 1m. Therefore mgh for a ton of water falling 600m would be 5886000J, or 1.6kWh, which is a lot closer to the mark.

One question: How are you people getting kilowatt hours from a metric tonne of water flowing from a one meter height, through an unknown restriction, in an unspecified amount of time? Kilowatt hours is a time-dependent measurement and kilowatts is not. Also...the equation that Robert quoted, roughly, at 3:55 IS, indeed, 1kg dropping 1 meter equalling 1 kilowatt...but that has seconds as a component that need to be cancelled out in the next step (where you stir in time or flow rate) by also adding in the 3,600 sec/hour conversion if you want to get to kilowatt hours as your final answer. This is why some attempts are off by a factor of 1,000... Be Good almost had it but got distracted by the mental picture of a glob of water free-falling through space, instead of flowing through a pipe and turbine at a more measured pace, while doing the work of generating electricity. Andy Lee Robinson took something from his daily life and did a comparison that made hands-on sense to him...he gets the prize! I intuitively knew that Robert's 1, 1, 1 formula was right, but the math wasn't working for me...(it's been a while!)...I finally worked it backward using the flow rate of a small petrol-powered water pump to confirm my belief, then searched the interwebs a bit to find a similar, step-by-step, problem and suss where my math had gone wrong.

Bluswede, thanks for your comment... I'd just like to fix your confusion - kilowatt hours is *not* time-dependent! It is a unit of energy, regardless of time. Think of it like a bucket of petrol. You can spend 1kWh in 1 second (3.6MW) or one year (114mW) - it is the same quantity or work, but if you spend it quickly then that represents more power. Power is an instantaneous quantity, a rate of flow. like litres per second or J/s. Energy is J/s x time = J. Potential energy, mgh, says nothing about time - that is the energy to raise a mass by height against gravity, or released. If you want to do this quickly, then you need more energy quickly, ie. more joules per second = power. Hope that helps.

Conservation of energy principles do not require details of the processes of how one form of energy is converted into another. Lifting one cubic meter of water by one meter with respect to some arbitrarily chosen datum point near the earths surface requires a force acting opposite to the force of gravity over a distance of one meter. This also can be understood as the amount of energy to be transferred from the surroundings into the cubic meter of water where it is being stored as gravitational potential energy. Potential energy quantifies the work that gravity potentially could perform on the amount of water when it is returned back from its final position to the initial datum. This analysis yields an upper bound for the maximum amount of energy that the water possibly could transfer back to its surroundings. A real life process where water falls a couple hundreds of meters and gravitational potential energy is converted into kinetic energy, then passes through a turbine producing shaft work which is transformed into some electric potential difference by some generator will have irreversibilities and thus every conversion of energy will reduce the amount of useful work which can be performed with that initial amount of potential energy we started of with. Hence no details are required of how the cycle is performed by the power plant in order to state upper limits of what it can possibly do (or for that matter one cubic meter of water falling one meter). Here's how the computation was done: mass of one cubic meter: 1 m^3 = 1000 l = 1000 kg change in potential energy with respect to some datum to one significant digit: ΔPE = 1000 kg * 10 m/s^2 * 1m = 1E1 kJ unit conversion to kWh: 1 kJ = 1 kWs 3600 kWs = 1 kWh answer to one significant digit: ΔPE = 1E1 kJ * [1 kWs/kJ] * [1 kWh/3600 kWs] = 3E-3 kWh = 0.003 kWh. One mental experiment to adjust your intuitions: 1 cubic meter equals 100 buckets containing 10 l. To me it is fairly obvious that with some effort I could lift the filled buckets 100 times by one meter and put it into a 1 cubic meter box. I also know just how much effort is required to maintain some continuous power output above 100 watts [see kzbin.info/www/bejne/iWWyZqmlhKikd7M] much less an output of 1 kW for one hour resulting in 1 kWh. There is no way I possibly converted that much energy with my buckets.

The public Tour is fantastic where you board a Bus in llanberris Electric Mountain visitors center in the town, and are then taken under the mountain. You have to remove all Metal, Mobile Phones and place then in Bags. I was lucky enough to be there when they turned on one of the Turbines. The Initial Noise shook the Floor and the noise from that spinning Turbine is incredible, creating a Giant Electro Magnet , hence reason you cant wear any metal.
