And the lights all went out in Massachusetts But was left standing on my own , warm and dry ...... or at least that's how i remember the song we sang at school about solar power

You did not directly address the financial objectivity. In particular using the time value of money-assume the discount rate is 5% up to an investor/trader value is 20% per year. When you do this on $50k you get $2,500 to $10,000 per year. The electric savings would need to exceed these values. Very hard to do. I wish you well.

I really can't see how this new efficiency can overcome the intrinsic problems of storage. It is horrendously difficult to store and it is just SO dangerous and flammable. I can only assume that the hydrogen hype is all about attracting funding into companies that rely on fossil fuel sales. We should stop propping these companies up and move to proven green energy solutions as quickly as possible. We could have gone to 100% green energy years ago on technology that was available 10 years ago if we had the will to do it.

So still only feasible for upper middle class. Where that next gen solar panels!

Isn't an abacus a manually operated digital computer? The beads are moved by hand but they still represent an on or off state. The slide rule is an analog manually operated computer. I used them a lot before we got digital calculators. When I was in the Air Force we used analog computers (large ones) and they were fantastic machines.

If I could have an induction stove and gas oven I would be happy.

Why don't you help people by making some sort of calculator or excel file with the different things for people to consider to determine if it makes sense for them..

Good info. Would you mind giving the name of the good Powerwall installer? BTW, does the name of the bad Powerwall installer start with Dev*** ? Thanks

Loved this breakdown.

I wouldn't install solar because I'd feel like I rip off other rate payers and tax payers. It's just bad value for Sweden so while I may or may not save money on it, someone has to pay for more expensive power. If not me, then everybody else.

The scam is in the sales models! Sales dudes getting massive commissions. All of solar should be MUCH cheaper already!

I been using the miele for a few years now and while I like it it does heat up the room significantly and it makes quite a bit of noise. Also my electric bill hasn’t gone down at all.

Have you considered doing audio books? I have to say that I think your voice would lend itself very well to doing bodio books Please seriously consider exploring that as a career option A c areer in addition to what you currently do. And thank you.

It would be a godsend that if technology advanced to a point where we could have reliable alternative energy sources at the local Homestead level thus negating the need for a national energy infrastructure

Fair summary except the part where he misstates taking taxpayer subsidies for his generated power credits. He mentions HUGE increases in utility electric charges and how that’s decreased his net spend and break-even to 7 yrs WITHOUT seeming to realize that it’s THOSE subsidies both for installation and over-generous generation that are causing the historic increases. Who does he believe is paying for those “credits”? The utilities???

😂😂 Tesla works in their batteries...... 😂😂. You mean Panasonic is working.. Tesla haven't designed their on batteries.. all Tesla battery manufacturing is licensed from Panasonic.. and mostly they just rewrap Panasonic cells... 😂😂...

0:50 That's why you build ventilation into your new house yah genius. At worst, open a window. Get outta here with that framing. This ain't worth my time.

It's not a scam. It's a long term investment with so many risks. In the Netherlands, now we have to pay a monthly fee to return electricity to the grid. While energy companies and installers give you quotes based on certain assumptions, so many things can change between now and the break-even point.

OMG, LOL in California I pay $0.42 per kW. It is insane, delivery chargers are higher than actual electricity generation cost. At the same time I pay like $25-40 per months for natural gas for water heater. Bases on the Rheem energy guide sticker - it would cost me $515 per year to run heat pump water heater versus $350-ish for gas. And I have like 10 year old heater, newer models would be more efficient and run cheaper. So unless you have free electricity (in my area) - heat pump heaters do not make any sense. But even then - labor in CA is insane, a technician that serviced my heater last year told me (of top of his head) it's gonna cost me $8,000 to replace my heater with a heat pump water heater. To the point of free electricity - solar panels, again, in my area - are more expensive to install + now you have to install batteries since you no longer can use the grid as your battery. A decent system would cost you north of $25-30K after all incentives and tax credits... and that if you pay upfront. So... clean and green and sustainable all that is great but it makes very little financial sense unless you are rich now.

As an Australian I can confirm - my 7kw solar system cost $8k installed before subsidies, which reduced it to $4k. My solar system has already paid for itself after 4 years.

the valve supplying gas to the burners is to blame, it should open only when the burner is used and remain closed at all other times

You literally meant ground breaking.

I do believe where I'm at in Texas. Some of the companies overcharge by a lot. I've had them sit down, and I asked questions they couldn't answer. I knew about solar, then they did. The cost was not adding up for me, so I did not do it. Instead, I'm starting small, like really small. I got ahold of a small Bluetti solar generator and started to buy one panel at a time from Amazon. Now it is the older 200P and only does 700 watts solar, and outputs 2k watts continuously. I bought 4, 200-watt bifacials panels. And I haven't had a problem. Right now, I'm only running a lot of loads on the weekend when I'm off. But I will be installing a transfer kit that I can easily pick which circuits I want to run. So far, I've produced over 100kwh in the last few months. So is it worth it. I would say yes. Even starting small, I've seen a drop in energy consumption. I plan on upscaling to. Taking energy into your own hands gives more freedom and safeguarding for your family. That's how I look at it.

The biggest downside of induction hobs is that they never have knobs.

It's a moot point how much sun is actually used, since it is an unlimited resource. The more different ideas and products available, the better! The market will sort them out to the most inexpensive and durable items. Also we need to work on gadgets to clean these solar displays regularly. 💙💙💙

I have five panels I got for 10k. Knowing what I know now I could have done it myself, but I also have a twenty year warranty on the things which gives me huge peace of mind. I enjoy being less dependent on natural gas as well.

As a German citizen who has lost faith in our industry it always makes me happy when I hear that behind the scenes there are some local German and EU companies that still lead the industry and that our situation is not entirely lost. If only we could keep that momentum and not sell it al to china once again ...

Useful video, I had not previously come across information about the mandatory presence of radioactive impurities in rocks containing rare earth elements.

You mentioned using analog computers to calculate heat flow in objects. I remember using nonlinear partial differential equations to model heat flow in a metal bar from a point source. Bessel functions were used in the process of calculating the heat flow.

I am in "Sunny Southern California" so things work out a bit different. I had my initial 4.8 KW Enphase grid tied system installed almost 5 years ago. Plans, permitting, inspection, and labor were all a bit more than the national average, but the installer took care of it all and made the process very smooth. I had saved up and paid for the system directly. It was in 3 payments. 20% down for them to order the equipment and start the paperwork. Another 30% when all the gear was delivered and they started installing it. The final 50% once the system was producing power. My total cost up front was $17,000 USD and it qualified for the 30% tax credit, so I got back over $5,000 the following April. Final out of pocket cost is then $12,000 for 4,800 watts of solar panels. Due to the Sunny location, my small 4,800 watts has produced 8,000 kilowatt hours each year. The 4th year fell just under 8,000 due to more cloudy weather, but the 5th year is looking good for over 8,000 again. At an average cost of $0.32 per KWH from the utility (rates go from $0.27 to $0.69 depending on time of year and time of day) that means I am "saving" over $2,500 a year off of my electric bill. $12,000 / 2,500 = 4.8 years to fully pay off the system. But it's not quite that simple. The one thing none of the Solar Companies mentioned when I got quotes was that the electric billing was going to change. Before I had solar panels, I was on a tired power billing schedule. The first 300 KWHs a month was only billed at $0.17 per KWH. The Second tier was up to about 1,000 KWHs at $0.26 per KWH. And then "High Usage" beyond that was at something like $0.40 per KWH. I used under 500 KWHs in winter months, and up to 1,800 KWHs in 100+ summer heat. My bills ran from a low of about $70 to a peak high of $500. The total for a year would end up around $3,000 for electricity. My PV Solar power system went online in late July, 2019. The first few bills looked amazing. Just $6, then $8 and $7. Just wow. This is amazing. And it's crazy hot and the A/C has not stopped running. But then I saw the little box on page 5 of the electric bill. I am on a yearly "True Up Plan". I am only paying the taxes and "Non-bypassable Charges". The energy is being added up. At the end of the first billing year, I was hit with a $1,500 bill for the energy I used from the grid. Adding in the monthly fees to the True Up and I ended up saving less than 30% off of my year of bills from before I got solar. The pay off was really going to be more like 12 years. The main culprit here was "Time of Use" billing. Sure, I was getting "100% credit for exported power". BUT... All my power export was between 10 am and 2 pm. Smack in the middle of the cheapest time of day rate. That cheapest rate is now $0.27 or more than tier 2 used to be. But this is credit to me. But after 4 pm, and on to 9 pm, as the sun goes down, the rate jumps up to $0.52 per KWH as the solar panels stop producing and you have to buy electricity. OUCH!!! This was never explained. Had I known about that, I would have installed more solar panels and a battery system to provide evening power. This was not so much a scam as it was just, not giving all the details. Had I gone any smaller, my bills might have actually gone up. By the end of year 2, I had a hybrid inverter installed with 18 KWHs of battery. Originally it was setup to just store 10 KWHs when the sun was up, during the cheap time of day, and then discharge that 10 KWH's back into the grid at 2 kw for the 5 hours from 4 pm to 9 pm. That change cut my electric bill in half. I now use almost no high rate power, and most days still export some at the cheap rate. Adding the cost of the batteries and the hybrid inverter, the pay off time still got shorter with the new savings, but I also got backup power essentially for free.

C-14 has a radioactive power of 1W per kilogram, albeit for thousands years. So not suitable for automotive. SR-90 on the other hand...

My money is on "Quantum Computing." Go Qubits!

As it is with many things, the problem with many of these solar companies is greed. I'm here in rural Pennsylvania surrounded by farmland, so I decided to check into a cost of a system. I came to the conclusion that a 10kwh system worked best for me, so I worked with two different companies to get a quote. For the exact same service, equipment, maintenance, etc., one company came in at $32k and the other at $43k. That threw up all kinds of red flags in my mind, so I decided against it. If there's a new administration in the future that comes in with an all-inclusive energy approach with solar, wind, hydro, natural gas, clean coal, and most importantly, clean nuclear, energy prices are going to plummet. Of course there's no way of exactly predicting that, but when you're crunching the numbers long term, I don't think there's any way it financially makes sense.

John 3:16 For God so loved the world, that he gave his only begotten Son, that whosoever believeth in him should not perish, but have everlasting life. Isaiah 53:6 All we like sheep have gone astray; we have turned every one to his own way; and the LORD hath laid on him the iniquity of us all. Romans 4:5 But to him that worketh not, but believeth on him that justifieth the ungodly, his faith is counted for righteousness. 1 Corinthians 15:3 For I delivered unto you first of all that which I also received, how that Christ died for our sins according to the scriptures; 1 Corinthians 15:4 And that he was buried, and that he rose again the third day according to the scriptures: Ephesians 1:12 That we should be to the praise of his glory, who first trusted in Christ. Ephesians 1:13 In whom ye also trusted, after that ye heard the word of truth, the gospel of your salvation: in whom also after that ye believed, ye were sealed with that holy Spirit of promise, Ephesians 1:14 Which is the earnest of our inheritance until the redemption of the purchased possession, unto the praise of his glory. Ephesians 4:30 And grieve not the holy Spirit of God, whereby ye are sealed unto the day of redemption. †

I got panels installed by the company I bought them from. They include the cost of installation with the panels + inverter. I understand labor is expensive but for a 7kW solar installation like mine, it took around 3-4 hours for 2 people + me. I helped a bit but mostly I was watching. They needed a crane which costs a bit too. Thus, in total labor is say about 8 man hours. One advantage I had was when building the house, solar was thought about. I am not certain how much electrical guys charge in USA, here it is about 1.5x minimum wage. We have no government support except for no VAT on import. Application doesn't cost much, but it takes a long time. It took a month to get permit and after installation it took about 3 months before they started to count our grid contribution. In total I paid 7k$ish for 7kW solar + 5kW inverter (this is the legal limit). There is no law permitting battery installation yet. I will see how much that would cost once that law passes.

People gotta play out the scenario. For my folks home, it's a great location, ie single story home area with a roof facing 127º SE with the homes on a down slope hill and the energy costs would make the panels a nice money saver and roi within half a decade. The only negative is that they need to renew their roof completely because of past tree dmg(tree was taken down). Now I could do the labor myself as I've done roofing jobs before as well as helping a few of my buddies installing solar panels, but it's mostly material costs, especially thx to gas prices causing materials to practically triple in costs within the past 4 years. But that material costs is where my folks struggle, plus they also wanna get a professional to redo the roof for insurance purposes, adding to labor costs. It's just all a means of playing out the scenario and planning in the long run and for my folks, they just need to get their savings built.

Good take.

I am... undecided

Thank God for this video brother. At one time I was sold on this particular brand model. Until I found out the cubic feet.. Uhm no thanks can't wash a comforter,, or other big articles of clothing. Stick with the LG natural gas dryer

3d printed engine? good luck fixing it in space

I subscribed for the topics you cover. Unsubscribed immediately for how annoyingly you speak.

Please give a little more effort throwing the words from your mouth. Or completely whisper 😮‍💨

Heres my experience. I live in minnesota and the bureaucracy is excruciating. Regulation after regulation. Then if you do it your self you need it approved by an engineer if you can find one. After rebates i had 10,000$ in an 8 k system. Money wise it works but to pay an installer would have been 3x more money. we need to 1) make the paperwork easier and 2) make it easier to do it your self.

What happens if someone has a metal roof, then wants the solar roof? Does the metal roof get taken down? You said you wanted a metal roof for longevity but can't you have both even if it's obviously more expensive? Also, why didn't the "doubling" issue get fixed for everyone as an update? Seems like Tesla wants to lie to their customers and stock holders unless a RUclipsr is talented and popular enough to receive the individual fix. That's sketchy.

I think semantics is really important on this, Matt. It's not that the technologies are unreliable because they're old, it's because they weren't designed to work this long.

Wow, what a great video: Very balanced and well-researched! It took a lot of work and time to create this video!

Might not want to listen to Intel. TSMC is close to 1nm and then it will be the size of an atom.

Uh oh, I think I just stumbled on to my next hyper-focus.

there is a market for viciously low price solar panels. However can put that together and make it happen can make pure true real profit through volume.
