Whole home generator
Comments (55)A buddy of mine is using a micro hydro for backup power. When their power goes out he opens up the gates on a holding pond. The flow drives the hydro and powers his house and studio. He can get about 30 hrs from it before the pond gets down too low. I'm not sure if he's using a Turbulent system or not. He says that overall it's not overly efficient because it uses a lot more power to refill the holding pond than it generates but it's worked well for him. He's slowly deploying more solar so hopes that will take him mostly off-grid in a year or two. Yes, your buddy definitely has a problem... ETA: Do whatever you want, you have obviously picked your side in this debate and are out to discredit other sides. The problem being that your argument is largely selective and tangential. Saving generators from landfills with batteries... Great job, since the environmental impact of battery production is exponentially worse for the environment than almost any other product you might use in your home. Every pound of battery produces about 450 pounds of toxic materials just in the mining process, while production into batteries produces more than double that. Photovoltaic cell production is nearly as bad. If you want to be off grid, just because you don't want to deal with the power company that is fine. But if you are doing these things to be green, then putting micro-hydro generators on ponds that are not fed by natural streams is destructive and silly. Powerwalls and poorly utilized micro-hydro generators, like many other green technologies, are too often done because people want to show off their green toys....See MoreGreen HVAC system for Zone 4 house?
Comments (34)Well competing technologies win out and defeat other competing technologies. Or the flood of cheaper panels cause companies with greater cost panels to go bankrupt. There is a technology that could eventually win out again and clean the field again... probably more than that after that and so on. You say how robust the panels are, they withstand hail. They do this, they do that. None of you *that I know of* actually install solar panels and deal with potential problems. None of you *that I know of* perform warranty calls on installed solar systems. Certainly neither do I, but I know from my experience as a HVAC Service Contractor that crap happens. Things go wrong. If the things you say didn't go wrong... what pray tell is the purpose of the warranty? Hail? how big of hail? pea size. Yeah no specifics from none of you. I've seen softball size hail in my life time. I've seen golf ball size, pea size. The larger the size the more the damage... Million dollar homes have solar panels & ugliness. My personal opinion is that they don't look any more ugly than anything else on a roof. Ugliness is a matter of personal opinion. I live in reality. In that reality I know that if I were to buy solar panels I am not going to drive them down the street. But if I start hearing that solar panels on roof tops are catching fire OR the myriad of other problems that *that could happen* --- my goal isn't to bury my head in the sand and call these sorts of things fairy tales. The con is lets put this contraption on a million dollar home, because it will save a fortune in utility costs (which it may) ---- but then because we are so focused on saving a buck lets not maintain it. It just sits there on the roof... (it's not a car or truck) Then mysteriously we drive home one day...... 5, 10, 15 years into the wild blue yonder to see a black smoke over head. All that money we saved on utilities or what we thought we saved. Don't worry homes burn down (million dollar or less) for other reasons than having solar panels as an ignition source. So feel free to use that excuse if you want to. Technology is a beast unto itself. Boom to bust. One tech gets swallowed by another. 30 years is a long time in the tech realm. To put that into perspective that smart phone you have thinner than a stack of cards --- didn't exist 30 years ago. The energy market (electricity creation) is probably easily a $Trillion$ dollar market. In high tech world... that doesn't spell anything good for a 30 year solar panel in *todays* world. There's some problems with newer competing tech, but it's just a matter of time until something better comes along. What is top notch tech today, is dust tomorrow.

Comments (55)LOL, yeah the word "if" is so important in relation to the $0.39 cents per KWH that you claim some home owner is going to earn by simply dumping excess power back on the grid. Like anyone is going to really pay attention to the word "if" versus the more specific price that you quoted as if you were going to pay them out of your own pocket. I've already shown how important the word "if" is. I've shown your misleading statements about your own state New Jersey and how the program that you suggested was so great... was in fact being discontinued for something of a more 'fixed price'. The word "if" doesn't make your statements true. Doesn't negate what you said, how you said it as it was implied that someone could make $0.39 cents a KWH by selling back to the energy provider of choice. It doesn't work that way.... "if" you like it. "if" you don't. No matter, what I posted sets the record straight... with no "if's" / "and's" / or "but's" about it. The Truth, does not masquerade behind "if". ____________________________________________________ On the subject of California.... If California had no serious problems with debt, taxes, regulations, homelessness, lock downs, terrible traffic, prices paid for electricity at more than double the rate of many states... Why did Space X leave for Texas? Why have many others left? Why are net outflows larger than inflows? Here's another visual that tells a story......See MoreElectric vehicles
Comments (40)The only fuel currently in use in vehicles that's not explosive is diesel fuel, and even with the most modern technology, controlling emissions from diesel burning engines is more difficult than with gas engines. Gasoline is very explosive and its vapors react immediately to heat or flame. The risks and extreme flammability of lithium batteries in electric cars is a fact, not speculation. There have been numerous Tesla fire incidents too, with the company denying the existence of any inherent danger, as would be expected from a company that's overfilled with hype and puffery. Also there's the incident a few months ago of the auto transporter carrying a load that included a fair number of electric cars from Germany. Some batteries in which are believed to have caught fire and the ship ultimately sunk. Oceangoing vehicle transporters have been carrying gasoline powered cars across oceans for decades and there have been few incidents. Vehicles that use LNG (liquid natural gas) and CPG (compressed natural gas), don't ask me the difference between the two, have identifying letters on the back and have been seen in Europe for decades and decades. Often on fleet vehicles. Yes, natural gas is very explosive. The upshot - vehicles carry dangerous fuel. Hydrogen is likely no more so than others well known and used since forever. The certainty of demand for cars of any type other than gas-fueled isn't speculation, it's reality. State by state bans on sales of new models are that certainty, and the effective dates of such rules are not that many years away....See Morejakkom
