Electric Propulsion Reality Check

We see this now in our area with properties where a pole or three and a transformer are needed. Obscene numbers to get hydro to the house or houses. People saying screw it, drop 35,000 for solar and storage and not bother with hydro service.

Hi Phil,

Distribution charges are an issue where I live too. My "service" fee last month was $22. The power I actually was bill for was about $7. Then there was a city surcharge of $2, carbon tax of $0.10 and Federal sales tax of 5% on the whole bill.

However it is unlikely that you need 24,000 watts of power. It may be that 1/3 to 1/6 would be enough for an adequate grid tied system.

Don, for a grid tied system the trouble is ... all solar panels do is feed power back into the power company's system so that the power portion of solar panel owners' bills is reduced.

My power bills are now dominated by distribution system charges, which solar panels do not, and would not, help. Of course that is probably a California issue and not the situation in many other places.

Every time you open the fridge all cold air moves out and it has to start and work harder cooling it all again.
Darn ineficient yes.

Heres a better idea,fridge w slide out drawers so you can open just one at a time making it way more eficient



Was looking all over but no one sell this here,why not?

I wish there was a fridge that would limit cooling during the on-peak price period.

L.A. may have seen a 95/95 day a few million years ago. But the difference between 95 degrees and choose one 35% R/H and 95%, is about two and a half times the chilling burden. That's why I have 50-pint dehumidifiers. The A/C weeps an almost steady stream and the dehumidifiers fill 30 pints in seven hours.

And there's refrigeration. Chest freezers and a bottom freezer 24 cubic foot refrigerator. Batteries are supposed to do all that for three days and three nights. Knowing the greed of PUC's and the stupidity of government, gasoline will be twenty dollars a gallon, and you will need an Rx from an overpaid state agency to purchase and operate a generator.

Job pressure? Need to be there? Buy another car and keep it for emergencies.

But next to nothing cost for Electra-fuel, surely you are not naive enough to believe it's anything other than a come-on to get people, with the program.

Refiners are near ------ their pants with the thought of running their process units at 5% capacity and increasing their profits by 10,000%.

One does not allow The Big Bad Wolf to babysit Goldilocks.

Yet like most believers in checkist society, you're going to encourage government to take control of your life.

Worst case there is grid power. Any solar generated reduces that high cost grid consumption. Panels just wait patiently for the sun.

2800 kWh to cool a few rooms seems a bit high. Maybe close the windows?

Even when it hits 100 here I am only burning half that.

Or a billion campsites.
Got gnus for you. When I used A/C frugally in Mexico for a few rooms it amounted to 5,600 kWh for two months. A typical beginner's blunder. Electric power calculation is based on the WORST CASE, not the BEST CASE. My calculations are based in reality. 24/7. Right now at this moment, 94F -- 83% R/H. Could you tolerate it? Even the Mexicans are complaining. It was near 85F and 90% R/H at dawn With FOG. Your calculations must be based on 24 hour sunshine and legendary California 70F.

Whoops at 3:08 PM overcast, rain and lightning. Just like yesterday all the way back to Saturday

"HEY! NO FAIR" right? Amateurs think that way. Systems have to be conceptualized, laid out, engineered, built for worst-case not to have a freezer with $500 worth of food go bad. not to have an oxygen concentrator gather dust.

I've done a few hundred hours of workups on my system. It's the energy storage that is the killer. The batteries must be lithium and have the ability of a 240/200 amp system 24 hours a day for a week.

If you pretend anything is possible.
