  13. Most important cheaper than a Nokia N800 ($220)

Nice to have are:

  1. e-book reader is e-ink.
  2. GSM/EDGE/3G phone and data, but only if it is unlocked.
  3. GPS (not network based) for geocaching.

Ok – with these simple requirements, you’d think I’d have no trouble finding what I want? Do you know what I need? Please email= me!!!

Jan 2008 Update: I bought a Nokia N800

The Contrail Effect on Global Warming

Posted by JohnP 12/22/2007 at 10:34

Reference

Counter-intuitive impacts to climate due to man-made clouds. Not what you’d expect. Basically, smog is saving us from much worse global warming impacts.

Human greenhouse impacts add 2.6-3.0 W/m^2^

Smog (global dimming) has reduced it by 1.5 W/m^2^

Smog has saved us! Reducing smog without removing greenhouse gases will be the worst thing we can do.

Of course, this is all from PBS, so we probably can’t trust it.

Contrails over Southeastern USA

Total Home and Car Energy Electric/Hydrogen Hybrid Car

Why?

  1. Most trips and daily needs can be filled by an all electric vehicle
  2. Occasionally and for longer trips, the need for extended range and less than 5 minute fill ups is required.
  3. The car ’’must’’ have everything a current generation car has with similar performance and safety.

Ok, so most of the time an electric car is fine. The great thing about electric cars is that you’ve decoupled the power source from the car! All electric cars have very little maintenance required – there’s no engine oil or oil filter to change, no air filter to ahcnge and no transmission to fail. Recall the GM EV1 from a few years ago? According to lessors, they had no maintenance costs over a 3 year period. Nice.

With an electric car, whatever the most efficient electric power generation device is can be added to the vehicle to charge the batteries. It simply needs to fit into the place they last generator was.

Why hydrogen?

  1. Highly efficient electrical generation. The Fuel Cell is a highly efficient method of converting hydrogen + oxygen into electricity. Creating hydrogen is ‘’very inefficient’’ that’s why hydrogen created by solar energy is really the only answer. Centrally produced hydrogen is just another way for oil companies to overcharge us for something that isn’t any easier to mine or create than what you and I can do at home – over the long term.
  2. Local Storage – a couple 3000 psi tanks
  3. Simple and cheap raw materials – water
  4. Quick refill – less than 5 minutes to fill your car
  5. Can be used for portable, home or car electricity generation

Total Home, Car Energy Components:

  1. Highly insulated home – being half buried in the side of a hill would really help with insulation. R-38 roof; R-21 walls ; Zero Energy Home is interesting.
  2. Efficient lighting and appliances
  3. Solar Panels (5kW for an average home) Boston, MA home
  4. Solar Power Controller (when all batteries and hydrogen tanks are full, push excess energy onto the electric grid for others
  5. Heat pump with ground source heating/cooling; sometimes called horizontal loop geothermal heat pump system
  6. Hydrogen Generation System – car and portable needs
  7. Power Inverter for AC power
  8. Hydrogen Storage System – a tankful for the car + 7 days worth for the household energy needs
  9. Electric/Hydrogen Car – ideally, most trips don’t touch any H2, just electric power is used.
  10. Car Power Charger

Total Home and Car Energy

As an engineer, I’ve always been interested in efficient energy use. As gasoline prices increase more and more, I’ve become more interested in efficient automobiles. Between household and auto energy needs, and each of us trying to reduce our C02 footprint, it is clear to me that local energy generation is the only answer.
What do I mean by local energy generation?

  • Within our house lots, each of us should create, store and convert whatever energy is needed for our homes, A/C, appliances, heating, hot water, and most importantly automobiles for daily use.
  • there are exceptions where external energy needs to be provided, but generally we should each take responsibility for our energy needs locally.
  • With local generation, there is no ‘’one solution for everyone’’. It depends on what energy is easiest to create locally.

Some things are assumed:

  • natural gas will be used for central heating, unless another alternative becomes more efficient or is a common by-product of another necessary process.
  • natural gas will be used for water heating, unless another alternative becomes more efficient or is a common by-product of another necessary process.
  • wind energy isn’t a viable solution – I happen to live in the SE USA. Not much wind here.
  • hybrid automobile is required – electric + hydrogen
  • hydrogen must be produced locally (either convert natural gas or from electrolysis) from renewable energy sources.
  • potable water is available

Ok, let’s lay out the solution:

  1. Solar energy and batteries are used for household energy needs [[THCE Solar House]]
  2. electric + hydrogen hybrid cars are needed [[THCE e + H2 Car]]
  3. Batteries and/or converted hydrogen will be used for non-solar power generation [[THCE Batteries]]
  4. Hydrogen will be used for portable energy needs, local storage is needed. [[THCE H2]]

Home Energy Station

Posted by JohnP 12/10/2007 at 18:59

A few months ago, I wrote in my [[Thoughts On Energy]] that locally created hydrogen would be needed to convert cars from gasoline to hydrogen, even for commuter-only cars. Seems I wasn’t the first to have this idea. A few articles:

  • honda home energy station
  • Honda
  • Wikipedia
  • NY Times Article
  • Business Week Article
    The short version is they take natural gas in and provide these outputs:
  • hydrogen for the car ($600/month lease)
  • hot water for the house
  • electricity for a normal house (4+kW)
    Overall, about 30% less carbon is released than a normal house, water heater and car would require. C|Net did a very short story on this. I’d really like to see the natural gas not be the main method of conversion … perhaps solar panels & H2O could be inputs instead?

My only remaining question? Where to I sign up and how much does it cost? Sadly, the Honda FCX isn’t available where I live.

Toyota has a FCHV, but their trials seem limited to Japan.
What are US car makers doing?

Here’s a guy who decided to use Solar and Hydrogen similar to the way I suggested a few months ago.

Saving Rates needed for Individuals

Posted by JohnP 12/06/2007 at 10:56

I came across this article from my insurance company today that has tables and graphs the percentage of income that should be saved based on your age and approximate annual income.

The tables don’t cover all income levels and don’t address income increases over the years.

Many financial planners use 80% of your income as the target for retirement needs. People that plan to travel will need more. Quick summary for 80% replacement:

Age Income Savings Rate
25 $40K 10.0%
30 $60K 12.8%
35 $60K 19.6%
40 $80K 29.0%
45 $100K 42.8%
50 $100K 61.0%
55 $100K 97.0%
60 $100K 150%

Basically, if you haven’t started saving 20% of your income by age 35, then you are in BIG trouble!!! Plan on working until you’re dead, since kids and mortgages will prevent you from saving what is needed.

Table 3 in the article has the Assets Needed when you’re 65 to provide 80% cash flow. The table is in todays dollars and it assumes Social Security is paid and it is only for 1 person.

I’m worried that I over simplified this article, so take 10 minutes to read it.

eBook Readers

Posted by JohnP 11/30/2007 at 18:25

I was listening to a podcast today where they discussed eBooks. That got me thinking about what I want in an eBook Reader ….
A Kindle ?

  • Inexpensive – less than the cost of 10 paperback books and it needs to include 10 books with the device – less than $100
  • Small – smaller than a paperback book with 100 pages – think of all those pads on StarTrek, yep that’s the size.
  • Light weight – it should weigh about the same as a paperback scifi book
  • Beautiful reading screen – I don’t know how to explain this – but I know it when I see it.
  • Control of font sizes – 6pt.-32pt. At least 10 different sizes.
  • Open platform – support both the proprietary and open document formats. HTML/CSS, TXT, common MS-Office files, Open Office files, PDF. Minimal graphics.
  • MP3 player – I suppose a case could be made for AAC and WMA protected formats, but that has nothing to do with my personally ripped CDs. This should be an option based on the extra memory to hold 200, 500, 500,000 MP3s.
  • Reasonable Battery life – rechargeable in under 3 hours and it should work 4 days for reading only; standard USB cable used as a charger, not some stupid proprietary cable.
  • Enough memory to hold 5-10 books; I don’t need 200 books.
  • Back light, but it will eat the battery, big time.
  • Looks like a HD when connected to a PC, OS-X or Linux device – definitely not MTP.
  • USB connect to full sized keyboard and mice
  • Quiet; auto-off if the page isn’t turned within a timeout period.
  • 1-handed use. Handy buttons and scrolling designed by a human factors engineer, not some other type of engineer or software developer. Customization of the button use would be nice, esp for left/right handed use.
  • Quick startup and back-to-bookmark; pagination shouldn’t impact my reading. Do it in the background.
  • Auto-sync documents with a folder on a computer
  • Password protected.

Ok, those are the basics, but I’d like a little more …

  • cell phone – GSM or CDMA; I should bring my own cell plan
  • Email / Contact manager; think CrackBerry with all that it provides
  • wifi for web browsing w/ WPA; minimal browsing
  • EDGE, UMTA, EVDO, 3G or faster wireless data
  • if the MP3 player is included, add a voice recorder (MP3/MP4, not WAV)
  • GPS – well, why not?

Most importantly, I don’t want to pay for a book twice. No checking back to a central server for post-purchase validation. No expiration of the content, books don’t expire. Transfer of the ownership – or loaning it out must be allowed. No matter what, 70 years later or until the copyright expires, I should still be able to read the book. Tagging bought books with personal information embedded in the book DRM is fine – name, address, email, and credit card number. This will cause folks to be careful with each book.

Ok, so when we’re all done,

  • you still pay for books
  • you don’t need a different cell phone device
  • you don’t need a different music device
  • you don’t need a special charger, any USB charger will work

After writing all this down, it seems converting a BlackBerry into an eBook reader would be easier than adding email, calendar, and internet connectivity to an eBook.

Someone on /. recommended this @ $130.
