Elon Musk introduces the TESLA ENERGY POWERWALL

newtboy says...

I use slightly less than that myself on average, but we have solar water heating (supplemented with gas), so that's a good savings (especially since it also heats the hot tub), and we replaced all our light bulbs with led bulbs when they became feasible last year. Now, we usually read between 400 and 1000 watts during the day (depending on how many lights I have on, and if the refrigerator is cycled on or not.) That's running a big screen TV, computer, and often ps4 almost all day, every day. We also have electric stove and oven...and I weld, adding somewhat to our total.

Yes, my battery bank is only useful for power outages. It's enough to keep the lights on and the fridge from thawing, but not much else. We get about 3-4 hours out of it if I don't notice the power went out, but can make it all night if we conserve. Our system is grid tied, and first powers the home, then tops off the batteries, then sells any excess to PG&E. To date, I've never drawn the batteries down to zero...but we do have a small generator to supplement it when the power's out for days. The average home would certainly need more, but a 10kwh battery should be plenty to make it through an average night without AC (we don't have AC here).

My current system could not produce that much, but close. I live in N California, one of the foggiest areas in the US. Because we have a renter, an electric hot tub, dishwasher, and electric washer and drier, we use slightly more than we generate at this point, but my system is upgradeable to 6500 watts of generation (I have less than 1/3 of that now) when panels get cheaper...and when I can find space for more.

My system is not flat to my roof, and I have 2 strings of 8 panels. With the solar water tubes, it takes up most of the south 1/2 of my roof (1200 sq ft home). I could maybe fit 4 more panels up there and still be able to walk around them to clean them, but any more and I'll need some mounting structure. I really want to add a small wind turbine to generate at night or when there's a storm...solar doesn't work in the dark.

In America, we still have some rebates for people adding solar to their homes, but they are drying up fast. 15-20 years ago, you could almost do it for free if you got every rebate available.

We used to have about 1-2 weeks of power outage where I live per year, and that was part of why we did they system. We hated having no power and losing food every year, and also hated paying the ever rising cost of electricity. Before adding our system, we had $4-500 a month electric bills, now we have <$100 in winter and sometimes a negative bill in summer...we pay our bill once a year now, lump sum at the end of 12 months.
On to your second post....
I often think...electric cars were popular and the norm in cities before Ford came along. It's still astonishing to me that it was basically dropped for a century as a technology (with minor exceptions). I'm glad someone had finally gone back to it and is trying to fix it's issues. If I could afford a Tesla, I would have one.

I also agree, people won't adopt the technology as long as they have to sacrifice lifestyle for it. I said the same thing, but I found that I don't change my lifestyle at all with my solar system, I just pay lower bills. I determined that buying a system would pay for itself in under 10 years, with the lifespan of a system being about 20 years, that's 10 years of free electricity! That all assumes electric rates didn't go up, and they certainly have gone up...but not for me. You just need to be sure you install enough panels to supply all your power, and you're there.

The battery thing is really mostly for non-grid tied systems, or emergencies. Most people don't use batteries at night, it's simpler and cheaper to just sell power to the grid during the day and buy it back at night if you can, using them as your battery. Perhaps this battery will change that, but with lead acid, it's hard to make them worth the cost.

Panels aren't that expensive, really. In many areas, with rebates, they can be near free. (some companies will even give them to you and split the power generated off your roof). It's a myth that solar is expensive...when compared to non-solar. Mine are paid for by bill savings already (8 years + in) so I'm saving money with them now, and my lifestyle has not suffered in the least. I have lights on if its dark, I watch TV all day, and use the computer all day, have tons of electric devices I use, and soon will power a pond, etc. I often think that my life is a much better example of how you can be 'green' without much change than Gore's. He really doesn't seem to walk the walk, but he can sure talk the talk.

Blackout City

newtboy says...

Where I live, in the boondocks of N Cal., we usually have a few days of power outage a year. On those rare occasions when there's an outage and a clear sky, we get to see this. There's nothing like sitting in your hot tub, looking up at the night sky FULL of stars, and watching the international space station get re-supplied, and noticing how many satellites cross it's path every orbit. I feel like we should have at least one 'blackout' night per year worldwide, where we do our best to not use outdoor lights in an effort to show this beautiful expanse of nature to those who never get to see it.

3D Display Projects Images Into Mid-Air (No Screen)

newtboy says...

My thought was actually to have multiple projectors per block approximately 10 feet up (building mounted) with sensors to identify people and have them 'place' a smallish ball of light at about 8-10 feet up that floats above and in front of them, but with much less light needed than a 'street light'...and maybe stationary one's in intersections (these could even have 'covers' to stop wasted light from going up). Or, it could project tiny lights (like in the video) near ground level to illuminate the sidewalk, but that's not as useful by far.
By my estimation, there could be less pollution because there would be fewer, smaller lights on at any one time (where normal lights are just ON all night). I agree, there are many issues to solve, but it's doable if thought about thoroughly.
It's a little too late to worry about 'light pollution'...in fact I bet it's not on the average person's radar. Sadly, many people in cities have never seen stars at night and don't have a clue how much is hidden from them. (I live in the boonies of far N cali, and we still have light pollution from nearby towns, but nothing like in a city...I've even watched the international space station get re-supplied while sitting in my hot tub! That was amazing!).

Bill Nye: You Can’t Ignore Facts Forever

newtboy says...

Oh Bob. It's better to remain silent and let people think you an idiot than to open your mouth and prove it.
97% is not the same thing as 97. Also, the correct number is really closer to 99.9% of all published climatologists, if not higher. Those who know, know. Those who believe don't know jack.
There are many ways to differentiate human produced CO2 from naturally occurring CO2, and therefore prove the rise is due to man. This has been done repeatedly and conclusively. The simplest way is to simply look at the graph of the rise and compare it to our use of fossil fuels, they are exactly the same curve at exactly the same time, with exactly the same dips and bumps. It's certainly not the only method, but is a simple to understand one.
It's ridiculous to state that to live 'green' you must live as if in a 3rd world country. That is simply BS stated by unreasonable men without any knowledge (and usually with a financial incentive to be anti-green/pro-fossil fuel).
It's also ridiculously ignorant to state that being 'green' is not cost effective. As someone who has had a solar system for 7+ years, I can tell you it's paid for itself already (with an estimated 13 more years before needing serious upkeep), has kept me away from the 40-50% rate raises that have happened to others in that time, it heats my house, my shower, and my hot tub and keeps the lights, TV, washer/drier, dishwasher, and fridge on when the grid goes down. It's not at all the expensive, powerless, sacrifice forcing technology you seem to think it is. It saves money even in the short term, and significant amounts in the long term AND has many other benefits. You've been listening to the wrong people about this issue, people who either totally don't know what they're talking about or are bold faced liars. I speak from actual experience.
Cost effective 'green' technologies have existed for well over a decade. You are simply wrong about your estimations.

So there are 97 "scientists" that say unequivocally the sky is falling and you are buying it.

How many Climate Scientists are there in the world? Surly more than 100. What about the other 200 - 300 scientists? Do they agree?
This Carbon dioxide you claim to be the doom of man, how can you differentiate between man made and naturally made?

If you really care about this then ride a bicycle and eat only locally grown food and cut you electricity. Go live "3rd world" and leave reasonable men knowledge in peace.

I'm all for cutting fossil fuel and going "greener" but it has to be cost effective.

Who is going to buy a Chevy Volt at 60K when you can get a gas car for 30K.
Oh wait the Chevy volt was a financial disaster because it cost too much.

What happens when the coal fired electric plants stop producing electricity due to government "green" requirements that they can't meet and you electric bill goes up 30%? are you cool with that?


I think it will take 50 more years to get to cost effective "green" technologies.
Until then keep strong in your 3rd world hut..

I'll invite you over to my electric air conditioned house. I'll even pick you you in a gas power car.. Heck Ill even let you take a warm shower and do you laundry in that electric thing called a washer.

What If You Stopped Drinking Water?

chingalera says...

Never saw my granny ever drink water. Diet coke, iced tea, and crappy merlot (w/ice and sweetener) every once inna while. She was one if those 'fish fuck in it' folks, if you mentioned a glass of water to her she'd always get the same wince on her face...

Snow Swimming

Shepppard says...

....ever sit in a hot tub for a while, and then decide it's time to go back into the actual pool.

...and then go "Holy Balls, this pool is FREEZING"

That is why your comment will not work, and would instead be, from "augh!" to "AHHHHHHHHHHHHHHHHHHHHHHHHHHHHHHHHHHHHHHHHHHHHH
HHHHHHHHHHHHHHHHHHHHHHHHHHHHHHHHHHHHHHHHHHHHHHH
HHHHHHHHHHHHHHHHHHHHHHHHHHHHHHHHHHHHHHH"

Do that after 10-20 minutes in a sauna and it'll go from "augh!" to "ahhhh".

Why I Hate Composing E-mails

enoch says...

@Lann
i thought about that after i wrote the comment.
i left it as is so at least eric and lucky would know i was a fan.

another side benefit,which is one i was alluding to,is you calling me out and pointing to how my suggestions may have no practical application when dealing with anxiety.

which lets them both know they aint alone.

that make sense?
seems i may have to join eric and lucky in the hot tub.so many of my comments lately have been totally misinterpreted.

has me second guessing myself.
