Join Matt Ferrell, and his brother Sean Ferrell, as they discuss electric vehicles, renewable energy, smart technologies, and how they impact our lives.
Heat scavenging is best achieved by having all of your heat sources in one utility room. New German homes have these. Fridge and freezer compressors can be detached and extended to operate in the utility room rather than the kitchen. You can install a vent fan behind the oven to draft air past it and into the utility room or outside. Putting your server rack into your utility would be a huge gain to you personally.
Except there will inevitability be also D-D fusion which produces neutrons. You can't tell deuterium to fuse only with hellion, deuterium will also fuse with deuterium
For your server room to water heater heat pump, all you need is an 8” duct and your heat pump has a way to attach a duct to either the air intake or output.
7:40 Heat exchangers work: but the difficulty is that you don't want to send particulates from your kitchen , laundry, and bathroom through your heat exchanger. So you need to add what are essentially HEPA filters to the line, which would require periodic replacement. Not replacing the filter would be a fire hazard.
I have a second home in VT. I tried to get Tesla to install soalr and battery but Tesla gave me a bit of a run around about my roof. I replaced the roof and still they cancelled my order. So i then just ordered a Powerwall from Tesla. They installed that. I signed up with VT's Green Mountain Power virtual power plant so they can use my battery to maintain the grid. So far it happens about once or twice a month. They pay you up front for the kWh they can use so they paid me about $3600 when I signed up for 10 years. That is great as it helps off set the cost of the battery up front but I would prefer to get paid per usage. I doubt they will abuse the battery but only time will tell. I am now installing a small solar system myself from Wholesale Solar so I can get some solar power as well. It is just over 3kW.
23:00 Thank you for this presentation. I have been studding the recent evolution of the power grid. I enjoyed you comments. about not going Off Grid. I live in the American southeast and think that we down hear are playing catch-up. Also, I watch a lot of other RU-vid video and many are anti-renewable energy. It is almost like they are reading from the same script. To them, I mention what is happing as the grid decentralizes towards more consumer participation, but none seem to get the idea. The consumer making money is a dangerous idea.
I have a reason to use a car as your battery. Old Nissan Leafs go for 5k with a 20-30kwh battery.. it’s cheap and supports V2G… who needs to drive the battery?
3:41 "Battle scene from Ben Hur" You really dated yourself Sean! 🤣 Speaking of weather, you should have been in Houston when hurricane Beryl decided to waltz though! 75 MPH winds with that heaping helping of rain.
Thanks for answering my question! It was prompted by Fisker potentially selling off their remaining cars for as little as $14,000 - literally buying a cheap EV for no other purpose than being a battery.
Is there anyone capturing their water from their A/C or heat pump? Is this water suitable for watering plants? I'm doing this with my new mini split here in TX because it stops raining through most of June, July, and August and having this extra water is helpful. I can collect 2-3 gallons per day with my 2-ton unit.
We installed AGM Batteries four years ago and just ordered some Rhino 3 Lithium batteries. We did this because at the time AGM was cheaper and 100% recyclable plus we'd get paid for them to recycle. lithium at the time wasn't recyclable and were dangerous. Our plan was to buy cheaper batteries to get us through as many years as possible in the hopes technology would get better. It has but I wish sodium batteries were an option today. The Rhino 3 is a older battery being discontinued as we got a heck of a deal on them. About half the cost of our AGM's with more than twice the capacity. These new Rhino 3 batteries should last twice as long so by the time we have to replace them I can't imagine where battery tech will be.
12:35 “hammering the battery of your car” I have my BYD Seal’s V2L connected to the “Grid” input of my solar inverter (I don’t have a grid connection - I’m off-grid) I can power my house all night and use 8% of the car’s battery equivalent to 46km of range loss. I can charge that back in less than an hour. I have 36kWh of LFP solar batteries and my car has 86kWh (gross) LFPs. The car is actually much more efficient in it’s use of power than my solar batteries. In terms of cycles my house batteries on their own cycle once every 2 days, the car would be over 12 days. (Videos on my channel)
Regarding your electricity bill credit, here in Texas solar has become so popular that power companies (yes plural, it's Texas) have implemented monthly caps as it was impacting their bottom lines. I went for 4 years without paying an electric bill, but now I do have to pay the connection fees, taxes, and an occasional small electric bill in the winter if I don't hit the cap. No more accumulated credit. I expect time-of-use to eventually go away here as EVs become more popular and everyone is charging them overnight, and charging house batteries from the grid overnight could impact that as well. All of that is merely a change in policy and/or regulations. Hopefully everyone can adopt to these type of changes fairly easily. It has definitely had its challenges for me, but I am more or less back to net zero overall.
Not sure whether they are directly applicable to the USA in terms of type but we have many many more options available in the EU/UK/Australia than you appear to have readily available (ie not directly imported from China). |I suggest having a look at SigEnergy - it's available in Single 3/4/6/8/10/12kw and Three Phase upto 25kw versions that stack on top of upto 6 batteries (currently available in 6/8kwh with 10kwh coming next year). Each battery is a self contained unit with its own integral BMS. You can swap out one of those battery options for a V2X 15kw or 25kw DC EV Charger that can draw from Solar PV, Batteries and Grid at the same time. Further you can parallel multiple stacks of inverter/batteries. Connected to a Gateway device which has 0ms switchover (compatible with Medical Devices ie Respirators etc) the simpler, residential, gateway can take 3 parallel stacks - so potentially 3 x 6 x 8 = 144kwh (or 180kwh when 10's are available).
My geology instructor (probably a decade ago) did her doctoral thesis the previous year on the decontamination of ground water. The gallon had toxic levels of jet fuel and it took her a month in a university lab to make it potable...
the problem is each power company has its own regulations and programs. each state has hits own regulations and programs. I mean li live in "the county" but across the street it is "the city" so latterly across the street different regulations apply
My comment isn't related to the show but It would be cool if you could talk to the owners of you old house and their thoughts and feelings about it after a year of living in Matt's old house.
I watched a video that talked about how a server farm's heat us being used to warm up the Olypic pools in Paris. And how they are trying to find other ways to use that heat, like for green houses. Great video as always.
Both Australia and California are now having solar surplus at various times of the day. So enjoy your profit taking now before they shut you down and not buy your solar power which then will increase your utility bill.
Best heat reuse I’ve employed was crockery storage above a chiller for warm plates. Here in Britain “standard” electricity is 25p/kwh, between 16:00 and 19:00 it’s 36p, but there are 2 cheap rate periods 04:00-07:00 & 13:00-16:00 of 12p on a tariff called “Cosy Octopus”
Basically left versus right conservative versus liberal or progressive. Are just labels that are convenient and lazy. Go through issues one by one or go through legislation and policies implemented one by one without telling the people whose idea it is or labelling the idea. There is so much commonality. For example, the minimum wage, getting paid a fair wage or a fair share of profits, the discrepancy between the wealthy and everyone else, a single bear healthcare system, and so on. There have been coal miners on strike that literally want nothing to do with Bernie Sanders or the left. There are so many examples where lables skew thinking such as government programs bad but social security good, government health care bad but Medicare good.
What a joke. Conservatism is a reaction to the left or whatever he said I’m just paraphrasing. This is literally the chicken and the egg argument. So basically you’re saying if the left would just pack up and go home Everything would be peaceful and everything would be great yeah but Great whom.? Remember the good old days? For whom?
Q: How realistic would it be to buy an EV and just use it as a home battery? Given your experience with sprinkler limits not applying to 'cars'... Looking at Fisker Oceans potentially being *only* $14k seems like an interesting deal
If there is anything I have learned from this channel and others when it comes to building a newer home is, you don't have to break the bank on the first go. Start with the cornerstone of the entire thing and that is the house itself. If you have a leaky house, it doesn't matter how much you spend and on what tech. Your house will literally suck. But what you can do is build an airtight home, follow the manufacturer specs for your build, because different build mats require different ways to build a better home. Then you preplan your "dream scenario". Adding solar for example. Roof or ground? If roof, and you can't afford a full 48 panel array, okay, get 2 or 5. You can ALWAYS ADD later. You just have to preplan. Budget your best build of the house now. Plan out your future and knock those items off your list as you save money just by having a well built home and saving on energy use.
hope i'm not too late to the party but I got my PhD on exactly this subject (quantum dot solar). The thing that sold me on the idea was quantum dot inks and the promise of roll-to-roll processing Think about how fast we can print newspapers or leaflets, but they'd be solar cells instead. The flexible PV cell Matt was talking about is exactly where that's going. One of the papers I cited in my literature review estimated about 4 cents per watt. Most of my work was on ligands and trying to build exactly that road analogy Matt was talking about. Our lab tried to use "prefab highways" by adding carbon nanotubes and graphene, I tried to grow mine using organic ligands that polymerized together in the solid state, connecting adjacent dots together. We did most of the processing under ambient conditions which lowered the efficiency but was a better test of durability and had lower cost.
Mixed flock of goats & sheep which do a great job on the pasture part of our ~5ac. But does all that clear-mowing help our fire insurance prospects in northern CA? Nope. On the ‘interface’ zone, it doesn’t matter what you do unless your whole ‘neighborhood’ does a hardscape only surround and remove all trees (we have redwoods!). This is the blindness of the insurance companies.
