Ask Slashdot: LTE Hotspot As Sole Cellular Connection?

Mr D from 63 Re:Battery life (101 comments)

Good points on battery life. Having the hotspot and the device constantly connected to each other, and monitoring the internet for incoming calls probably will run the batteries down quickly on both devices. Mobile hotspots (I've used a Huawei 3G with great results) will often 'sleep' when not used for a certain period as well, so that should be considered.

As for VOIP service, Vonage ($$) has a nice feature that allows you to share your number between your home phone and mobile devices, and voicemail email alerts, which might be handy in such a setup.

You can stop auto updates on Android devices for the most part, but switching back and forth to auto/manual or manually implementing updates is a bit inconvenient.

Michigan About To Ban Tesla Sales

Mr D from 63 Re:Telsa's lobbiest crashes (292 comments)

And the laws should be changed, but they won't get changed as long as people keep fooling themselves into thinking its about keeping Tesla out. The dealers don't want a sales model that allows direct sales because then the other auto makers can cut them out. Its not about competition with other brands, its about their own manufactures cutting them out. Many folks won't even take time to try and understand why the laws were created to begin with. It had as much to do with consumer protection and price fixing as anything. Things have evolved.

But, it makes a lot of people feel better about fighting on behalf of Tesla, and they do deserve credit for aggressively pursuing change and using their popularity.

Wind Power Is Cheaper Than Coal, Leaked Report Shows

Mr D from 63 Re:XFD @ wind subsidies costly cf. oil (608 comments)

So, you don't care what you get for your money? Everything should get equal subsidy no matter the payback? I wonder if you've even seen credible numbers and how they are really spend and attributed.

For example, what you also don't see is the huge tax returns fed by nuclear. A typical unit pays over $10M/year in local property taxes, not to mention the large number of highly paid workers at each plant. A big chunk of solar subsidies goes to China and returns very little in tax's to the local communities.

And, if clean air is important, nuclear subsidies have produced many times the return for the dollar than wind and solar.

I think you care more about your vision of the ideal than about how wisely the subsidies are spent.

Bill Gates: Piketty's Attack on Income Inequality Is Right

Mr D from 63 Re:Progressive tax on consumption?? (832 comments)

There are many ways to make a consumption tax progressive, and it is progressive by nature in that those that consume more pay more.

First, eliminating tax on food and basic necessities greatly helps lower income folks. If need be you can have certain exemptions for people with lower incomes that allows them to get a return. What really matters is what is taxed and how much.

Bill Gates: Piketty's Attack on Income Inequality Is Right

Mr D from 63 Re:This looks like a nasty trick. (832 comments)

We already tax consumption at the state level. You could argue that having a higher available spending budget from not taxing labor would increase the spending power for many even after consumption tax is added, but it all depends on what is taxed and how much.

I think the greater concern for consumption tax approach is that it could driven the emergence of a huge black market. But, since that might mostly include lower end items and benefit lower income folks, it might be an acceptable flaw.

We either have to shift our approach or move to a system where lower income folks have greater capital investments, be it in retirement or other, but that approach, IMO, drives much great risk for high end corruption.

Can the Sun Realistically Power Datacenters?

Mr D from 63 Re:Obligatoriness Extraordinaire (236 comments)

Just looked back, because your point is valid and its good to check numbers.

The presentation does show a year over year additional production from solar at 1.8 TwH in 2013. So, you add that to total solar production, which will bias the error toward a higher capacity factor, and get about 10%. Its a reasonable approach of estimation because it is well documented that solar installation rates have not been increasing in the last few years, and is biased in favor of a higher capacity factor.

An alternative would be to find the actual capacity installed in 2013, divide by two, and subtract it from the capacity value before calculating, but I don't have that number, and it would still have error since it would assume a steady installation rate throughout the year.

Can the Sun Realistically Power Datacenters?

Mr D from 63 Re:Obligatoriness Extraordinaire (236 comments)

There may be some margin of error there, but the number is consistent with other real world numbers. As I showed elsewhere, the top end capacity factor for PV plants in Germany is about 13%, with many close to 10%. Residential PV knocks the average down because a high number of those panels are not installed at optimal angles. So, you can nit pick over a percent or even two if you want, but if you are doing that you are making the "fatal mistake" of missing the point that low capacity factors are very real in places like Germany.

The numbers shown on the charts embedded in your link are consistent with what I was saying. Germany, overall, is worse than our NE. You can see it all together at one time right here;

https://lh6.googleusercontent....

And the actual capacity factors of German PV bear out that at best they get 3 - 3.5 hr/day (or 0.13 capacity factor). Real world data is always best.

Can the Sun Realistically Power Datacenters?

Mr D from 63 Re:Obligatoriness Extraordinaire (236 comments)

The numbers for tilt panels are different than the numbers for fixed panels. A fixed panel basis is the standard for solar insolation and related comparisons. My numbers are for fixed panels, which make up almost all of the installations. Tilting and tracking are rarely installed.

So,presenting tilt panel numbers when they are not really being used is kind of misleading. However, even your tilt panel numbers are lower than Angelo-shpere insists exist, so I'll let him argue that point with you.

Can the Sun Realistically Power Datacenters?

Mr D from 63 Re:Obligatoriness Extraordinaire (236 comments)

15 years is, what I would say, bearable. That is, if it proves to be highly reliable. That must include all costs, not just the initial CAPEX. If the thing will work for 30 years without complete overhaul, even longer might make sense. If high maintenance costs and a lot of down time are seen, and so there needs to be extra reserve to compensate, then the payback better be a whole lot shorter.

Can the Sun Realistically Power Datacenters?

Mr D from 63 Re:Obligatoriness Extraordinaire (236 comments)

Sigh.

The best solar PV plants in Germany have a capacity factor of about 13%.

http://en.wikipedia.org/wiki/S...

These are the plants in the best locations. That comes to an average solar insolation of 3.12 full sun hours/day. If you had 5 hours you should have closer to 20% capacity factor. I'll let you think about why they don't see 20%, and why the average capacity factor overall is 9.5%, and try to reconcile it yourself. When you get stumped, I'll gladly explain.

Does Lockheed Martin Really Have a Breakthrough Fusion Machine?

Mr D from 63 Mr D from 63 writes  |  yesterday

Mr D from 63 (3395377) writes "Some followup to the recent /. article on this topic;

Lockheed Martin’s announcement last week that it had secretly developed a promising design for a compact nuclear fusion reactor has met with excitement but also skepticism over the basic feasibility of its approach.

Ian Hutchinson, a professor of nuclear science and engineering at MIT, says he was only able to comment on what Lockheed has released—some pictures, diagrams, and commentary, which can be found here. “Based on that, as far as I can tell, they aren’t paying attention to the basic physics of magnetic-confinement fusion energy. And so I’m highly skeptical that they have anything interesting to offer,” he says...

Netflix Says Ultra-HD Content Costs More, So Subscribers Will Pay More

Mr D from 63 Mr D from 63 writes  |  about a week ago

Mr D from 63 (3395377) writes "From the article; "A higher-resolution, 4K stream from Netflix (NFLX) will cost more. The company has boosted its monthly price for streaming ultrahigh-definition television and movies to $11.99 per month, citing the higher expenses associated with that content. In May, Netflix announced that its original series, such as House of Cards, would be available to stream in the 4K format, which offers roughly four times the resolution of current high-def TVs.""

Mr D from 63 (3395377) writes "On Saturday, May 10, 2014, at 2 p.m. local time (10 p.m. Friday EDT), the hybrid remotely operated vehicle Nereus was confirmed lost at 9,990 meters (6.2 miles) depth in the Kermadec Trench northeast of New Zealand. The unmanned vehicle was working as part of a mission to explore the ocean’s hadal region from 6,000 to nearly 11,000 meters deep. Scientists say a portion of it likely imploded under pressure as great as 16,000 pounds per square inch."

SEC Releases Long-Awaited Rules on Crowdfunding

Mr D from 63 Mr D from 63 writes  |  about a year ago

Mr D from 63 (3395377) writes "The Securities and Exchange Commission announced rules that will make it legal for entrepreneurs and startups to raise money by selling pieces of their company to everyday, mom-and-pop investors.

The proposed rules were released this morning and the Commission voted to adopt them. The rules will now be available for public comment for 90 days before a final set is drafted and adopted.

Proposed rules include;
1. Entrepreneurs could raise $1 million per year.
2. The amount individuals could invest would be capped depending on their net worth.
3. Equity in a company must be held for one year
4. Transactions must be supervised by an SEC-registered intermediary
5. Only U.S.-based companies would be eligible to crowdfund
6. Financial disclosure requirements. Companies that participate in online equity crowdfunding would need to disclose who are their primary officers and directors and anyone who owns more than 20 percent of the company."
