Minor updates on Powerwall battery

A few more tidbits on the new batteries from Tesla I discussed here, here, and here. Accumulating the info here in case I go into more detail in the future.

5/1 Bloomberg News – SolarCity Taking Orders for Tesla Batteries Starting at $5,000 – You can place an order now for a Powerwall backup battery. The 10 kWh backup can be purchased for $7,140. Price for just the battery is $3,500, so the inverter and installation will run you $3640. Installation only runs about $1,500 I think, which means the inverter is running around $2,000. Need to add that into all of the previous calculations I made. That further reduces the economic value of batteries, solar, and going off-grid.

More good stuff on the open space and technology frontiers – 5/12

Several fun articles on space and one on self-driving trucks

4/18 – Commented previously that SpaceX’s third try to recover a Falcon booster rocket failed. It came down too fast, was unstable, and exploded. SpaceX already knows the problem. Elon Musk sent a tweet on 4/18 that said

Cause of hard rocket landing confirmed as due to slower than expected throttle valve response. Next attempt in 2 months.

Problem identified. I am sure the solution will be implemented 5 or 6 weeks before the next launch.

Very cool.

Get control of every domain that refers to your name, including all extensions

Back in 2013, I offered An illustration why you should gain control over your name on the ‘net, both through buying domain names and reserving your name at social media sights (oops, meant to say sites!).

To illustrate the concept that you should grab control over your name on the ’net, I pointed out a pro-Second Amendment activist who bought a domain and turned it into a pro-gun website to poke fun at an anti-gun politician.

The domain?

www.senatorfeinstein.com

I just checked that address and found out it is a dead link. It used to be an advocacy site. However, the joke (if you are into such things) and the point (which is the reason for this post) stand.

(cross post from my other blog, Nonprofit Update)

In recent weeks, a politician from the opposite side of the aisle got zinged. She is former head of a large technology company. Someone grabbed a domain including her name and put up a one-page site criticizing how many people were laid off during her tenure.

The domain? Continue reading “Get control of every domain that refers to your name, including all extensions”

More good stuff from the wide open energy frontier – 5/8

Some articles on the amazing things going on in the energy world: oil factories, fracklog, greener fracking and calculating the Saudi cash burn rate.

5/6 – Russell Gold at Wall Street Journal – What the Future of Oil Drilling Will Look Like – think “oil factory”. Liberty resources is developing a 10,000 acre complex that will have 96 wells when complete. It will be called Stomping Horse.

A pipeline corridor will link all the drill sites to each other allowing oil and natural gas to be gathered to one location. Freshwater can be pumped from a central location and saltwater gathered by pipe at the disposal well.

Going off-grid. Would merely triple what I pay for electricity.

One of the most fun things about blogging is learning as you go. If you like watching an uninformed person slowly get informed, get a fresh cup of coffee, sit back, and enjoy.

I previously discussed Battery storage for the home. Extremely expensive, but available. Update: merely double my costs.

(My math was off. Read to the end for my new calculation.)

Also More followup on the Tesla Powerwall home battery.

To analyze the concept of home batteries and solar power, I’m looking at the concept from the perspective of going off-grid.

I found a few websites that provided some info on the solar array needed. I won’t list the specific sites to avoid causing any unexpected problems, like, oh, exposing commercial businesses to unwanted ridicule.

One site gave helpful tools to calculate how many panels are needed. To go off-grid and cover our actual electricity use last August would call for a 7Kw system. That would involve $18,000 of their panels plus $1,500 or $2,000 for an inverter. Installation and permits are extra.

More followup on the Tesla Powerwall home battery

More comments on the nifty new battery for home use. Mentioned this earlier.

5/3 – Seeking Alpha – The Silliness of Tesla’s 10kWh Back-up Battery – Just a few silliness tidbits from the author’s long list of silliness factors: Continue reading “More followup on the Tesla Powerwall home battery”

More glimpses that disruptive change is already here – (radical change #4)

The disruptive change around us is staggering. Yet I don’t see how it will disrupt my business, which is the auditing sector of public accounting. Before I get into that, here are a few more articles on the change going on around us.

Just in case you are wondering what digital disruption looks like, check out this graph of newspaper ad revenue for the last 65 years, adjusted for inflation:

(Copyright Carpe Diem, used with permission.)

4/30 – Carpe Diem – Creative destruction: Newspaper ad revenue continued its precipitous free fall in 2014, and it’s likely to continue – Above graph is from this article, which points out that print advertising has dropped 57% in six years and is down 75% from the 2000 high 14 years ago.

Adding back digital advertising puts the volume of advertising essentially at the same level as in 1950 when adjusted for inflation. Phrased differently, it took 50 years to go from $20B to $67B and merely 14 years to lose all that growth.

More examples:

More good stuff on the Bakken – 5/4

Here’s some fun notes on interesting news around the Bakken. Big change on the oil tax. Slowdown is drilling is having some interesting impacts on the housing market. Also, tracking the rig count.

5/1 – Dickinson Press – North Dakota still on track for oil tax break – Oil prices in April were below the level which will trigger the “big trigger” tax reduction on oil. If West Texas Intermediate is below a threshold, currently $52.29, for five consecutive months the 6.5% oil extraction tax is waived for two years on wells started after the trigger is pulled. One more month below the cut off will trigger the drop.

Battery storage for the home. Extremely expensive, but available. Update: merely double my costs.

Tesla announced a new home battery product called Powerwall. A very cool idea. In spite of what you might think from reading my blog, I think this is a good idea.

5/1 – AP at Daily Bulletin – Tesla charges into home battery market despite challenges

It is merely the next step in a very long journey, but I can grasp the great idea. Someday storing electricity at home may be viable.

On the other hand, it is astoundingly expensive at the moment. On the other, other hand, that’s what happens at the front-end of breakthrough technology.

You can find more info on the battery at Tesla’s Powerwall site.

I’m going to stretch my knowledge, probably beyond the breaking point. Let me know if I slip a digit or miss a step.

Reusable shopping bags are so dangerous they require a warning label

Got a free reusable shopping bag today from the pharmacy where I shop.

Scan your card to get a handful of coupons and they give you a free reusable bag.

I have described the dangers of reusable bags previously.

This bag came with a warning label. It said: Continue reading “Reusable shopping bags are so dangerous they require a warning label”

Update on the open frontiers – 4/29

There are amazing things going on in the wide open frontiers of technology and eduction. Here’s a few articles that caught my eye.

Technology

4/6 – American Interest (Peter) – Jobs of the Future, Travel Agent Edition– Article suggests demand for travel agents is growing and could even outstrip the supply soon.

How can this possibly be? I thought the ‘net deleted the need for travel agents.

More good stuff on surveillance – 4/27

Here is my sixteenth list of good stuff on our surveillance society. A few articles of interest.

The depth, breadth, and speed of the surveillance continues to astound me.

4/21 – Schneier on Security – Hacker Detained by FBI after Tweeting about Airplane Software Vulnerabilities – Check out the speed of surveillance in this story.

While in the air from Denver to New York, a security researcher joked in a tweet about hacking specific airplane systems. When he landed, the FBI detained him for a 4 hour interrogation and confiscated his electronics.

A: 84% & minus 2%. Q: Percent of individual income taxes paid by top 20% and bottom 20% of Americans (actual for 2014)

Previously mentioned the percent of income taxes (excluding payroll taxes) projected to be paid in 2015: A: 48% & 0%. Q: Percent of individual income taxes paid by top 1% of taxpayers and bottom half (projected for 2015).

Here are actual numbers for 2014 for income taxes paid. Again, this is income tax only and excludes payroll taxes and excise taxes. The data is for quintiles of income. Each bracket of 20% of Americans includes about 65 million people. This is not based on tax returns.

More on stealing raisins. Oops. I meant to say, more on implementing the New Deal.

The New Deal policy of confiscating a portion of raisins from farmers every year in order to drive up prices to consumers has been previously discussed here, here, and here.

The Wall Street Journal provides more background on this foolishness that is being considered in the Supreme Court today: The Incredible Raisin Heist / A property-rights challenge to federal marketing orders hits the Supreme Court.

I’ve been wondering what the Raisin Administrative Committee does with all those raisins after they are surrendered by the farmers. Editorial points out the government may sell the raisins on the open market, ship them overseas, or just give them away.

I have to find someone far brighter than me to explain how selling the raisins or giving them away stabilizes prices. Seems that would drop prices to what would otherwise be equilibrium or even lower.

The WSJ editorial outlines the progress of the case through the federal courts. I promise you this is a paraphrase of the editorial and not the outline of a dystopian political novel I’ve been mulling over.
