It is obvious that there are lot of PR firm employees working for Tesla all over social media. A new roofing technology that is "zero risk". So many people are trying to "sell" Tesla roof here, reddit and all over social media. It's kind of sad.

I'm pretty sure that the vast majority (if not all) of the people trying to sell this are not paid, but simply doing so because they want solar power to be a thing.

People are thinking way too much about how much this saves them at a personal level. I think people should instead be thinking about how we can save the existence of the entire species, and all other higher order forms of life on earth, rather than focusing on their individual tax breaks, savings, or other trivial concerns. Yes, your cash flow is rendered quite trivial if life on Earth ends. Invest in the Life Econom…

I agree with the sentiment, but I have to correct your idea that global warming is a species-ending problem. The worst-case scenario of global warming (which might be inevitable given the current CO2 levels) is a 216 foot rise in sea level [1]. This will cause mass migration and be extremely expensive and unpleasant for society as a whole, but poses little threat of ending humanity. NASA's JPL did a great lecture a f…

213 feet??

It's all flash and no substance. Elon Musk is a great salesman and marketer. I'll give him that. But just like their cars, this roof is for the wealthy people who want to look cool and earn some liberal points. It makes no financial sense for the vast majority of people. > That being said, I love these things, so hoping it gets cheaper in the coming years. Yep. Perhaps in the future.

> But just like their cars, this roof is for the wealthy people who want to look cool and earn some liberal points. What does political affiliation have to do with this? People being excited about new and innovative technologies like electric cars, space travel, and solar roofs is great news for people reading a site like Hacker News - I don't think it would be out of line to suggest most new technology is marketed t…

> What does political affiliation have to do with this?

Well liberals love to pretend they are environmentally "conscious" while conservatives are "drill baby drill"? Right? Maybe I should have written fake california liberals.

I love innovative stuff. Solar roof isn't innovative.

> There is no need to make this into a "stupid liberals just trying to score points" issue.

I wasn't trying to score points. I was just being honest and offering my opinion. I'm fairly liberal myself...

Doing what? Evangelizing? Like you? Scouring this thread and responding to every comment that doesn't toe the company line?

> First off, we are not at existential risk from climate change. A bold claim indeed.

Not really. Even RCP8.0 wouldn't lead to extinction of the human race.

Does that include the increased risks of nuclear war, new disease vectors etc? Because, while the probable outcome is relatively little impact the butterfly effect means you can get some less predictable results indirectly.

Aka migration causes war X which due to _ spiraled into WWIII. Granted the world without global warming could alos end randomly as well so you can just say unknown unknowns are always a risk even if it does mean a slightly less stable geopolitical environment that does not nessisarily mean anything terrible happens.

Running calculations on what? Tesla's aren't even self driving in the first place. And there is no market for self driving uber cars yet. Who knows how much you can make off them. And if it was really 2k a month, Telsa would probably sell them straight to Uber instead of customers.

I need to replace my roof this year / next year. Cost ~15-20k for normal roofing, up to 50k for metal. I want solar on top of that and backup power. Just put my money down for this. Cost is under the 50k I was thinking about just for the metal roof!

Time will tell when they come out and do the survey to see how correct it is but I am excited.

Tesla acquired SolarCity in November in a deal worth $2.1 billion. At the event, Musk said Tesla's roof would price competitively with normal roofs and could even cost less. "It's looking quite promising that a solar roof will actually cost less than a normal roof before you even take the value of electricity into account," Musk said at the event. "So the basic proposition would be: Would you like a roof that looks b…

I'm 21, thus I have no idea what roofs normally cost. I assume they're very very heavily below ~80k? For a "regular" house, what would a roof cost? 4k? 10k? 500?

My roof is 1600 sq ft. It had a metal roof on it, which is considered more expensive than asphalt. It was 40 years old, which is the how long metal roofs are expected to last. I replaced it myself for around $2000. Most of the cost was $1600 for the metal roof. Then there was $400 in special nails and trim parts and sealer. It would have cost a little more if it wasn't metal before since I'd have to have added the spacers. Metal and asphalt replacement are sort of DIY possible, but asphalt is dirty heavy work. Metal is less dirty and dangerous, just remember to wear leather gloves. Also probably don't attempt if one's roof has more than a couple gables etc. It's better if you've done it before in any case. To have someone else replace the roof would have cost at least twice as much. Could be three times as much in some parts of the country.

If I were to have switched to slate or terra cotta or glass solar tiles I'd have to tear down the roof and rebuild it because normal houses in the US are not designed to hold that sort of weight, it requires a stronger roof structure, and sometimes stronger walls to hold the heavier roof. Possibly the rest of the structure would have to be reinforced as well. Doing this correctly requires a consultation with a licensed structural engineer. That sort of roof rebuild would cost from $20,000 - $50,000 depending on the scope needed according to the engineer, and that's before adding the roofing materials.

Yeah good luck with that plan. ("Honey, if we get a solar roof it will help the planet, but we'll have to put junior in the cheaper preschool to pay for it. Whatya think?")

It's unfortunate that people can't see that junior dealing with the effects of climate change in 30, 40, 50 years could be a lot more devastating to his life than the prestige level of his preschool.

We seem to care about relative outcomes vs peers more than absolute offset shifts for the larger group.

I'm not defending the quality of the calculations. Just pointing out that I don't think there was anything tone-deaf about doing them.
