Spaghetti diagrams, part 1

Spaghetti-2009

This “spaghetti diagram cheap adderall order adderall generic buy adderall canada ” (aka Sankey diagram, or Energy Flow Chart officially) is the 2008 version. Lawrence Livermore National Lab (LLNL) has been making these things since the 1970s. It’s more detailed than a simpler national energy flow diagram because it includes “rejected energy.” It’s also more complex — it actually includes within itself the electricity flow diagram. It’s a pretty cool visualization.

The main thing I dislike is that it doesn’t split up transportation or electricity generation “rejected energy” by sector. Since these are really the two biggest sources of “rejected energy,” you can’t see which group is the biggest “rejector cheap valium buy valium online no prescription today buy valium online no prescription today .”

Below, in an undated but funkier design, they’ve not only split up transportation into light duty vehicles, freight/other, and aircraft, they’ve also added domestic and net [...]

Choosing fun and beauty over high energy. Motivating positive behavioural change.

herbal valium buy valium online no prescription today valium overnight

I like the general concept of motivating behavioural changes for the low energy option by using fun, beauty, or good design.  The larger message here is that personal changes for climate change really need to be better, either more beautiful, more fun, or more healthy, than the other choices cheap adderall online adderall generic adderall uk .

Question from Steve Kirsch – Nuclear power plants.

capacity_factor,_us_nuclear_power_generation_fleet

“you want 3 TW of new nuclear.

that’s a 2.3GW plant every week for 25 years…
you have 1X 3GW plant a week for 25 years which would overshoot your goal.
am i missing something?”

First, and to be clear, I don’t “want” 3TW.  In doing the numbers on what would be required to stay under 450ppm of CO2 it looks like you need to create 11.5-12TW of clean power as well as keeping demand at current levels (16TW).  I tried to agnostically apportion that 11 buy valium forum buy valium online no prescription today valium online uk .5 TW across known working technologies, solar PV, solar thermal, wind, geothermal, nuclear, and biofuels.  It’s a thought experiment, and I would be happy with any solution for climate change, hence more or less of any one of these is fine with me as long as it all adds up.  And yes, 450 isn’t [...]

Contemplating my daily shower, during my daily shower.

shower

I love a hot shower in the morning. While it’s not a human right just yet, occasionally it feels like one buy adderall usa adderall generic adderall online without prescription .  So how much energy does it take to have a hot shower?

The simple version looks like this:

First we establish the conversion units…

liters_in_gallon=3 buy valium fedex buy valium online no prescription today generic valium .78541178

H2O_heat_capacity=4 cheapest accutane click here prescription accutane .18   (J/g/K)

seconds_in_day = 60*60*24

density_water = 1 (g/cm^3)

Now assume 2 gallons per minute of shower from my low flow shower head and assume 5 minute hot showers at 40 degrees celsius (about 100F) here visit us buy priligy malaysia .

showers_per_day =1

gallons_per_minute =2

minutes_per_shower =5

liters_per_shower = liters_in_gallon * gallons_per_minute * minutes_per_shower

grams_per_shower = liters_per_shower * 1000 * density_water

shower_Temperature=40

ambient_Temperature=8

shower_heat_Joules=showers_per_day *(grams_per_shower * H2O_heat_capacity *(shower_Temperature-ambient_Temperature))

daily_shower_Watts = shower_heat_Joules/seconds_in_day

shower_heat_Joules = 5063400
daily_shower_Watts = 58 order ativan online buy ativan mexico ativan generic .6038
Which is of course just [...]

The measurements of energy and power.

Energy is measured in Joules (J)
Power is measured in Watts (W).
1 Watt = 1 Joule / second

If you would like to quantitatively understand the relationship between your lifestyle, global energy use, and climate change, you need to establish the language with which you can translate between these things.
There are many different ways we use energy, many different ways we produce energy, and many different consequences environmentally.
Power and energy are being measured around us all of the time. You get your electricity bill in kilowatt hours (kWh), your gas bill in Therms or British Thermal Units (BTUs), your car’s performance is measured in horsepower, and your lightbulbs are rated in watts. To compare these things you need a common set of units adderall overnight delivery adderall generic cheap adderall order .
The first problem with comparing these things is that some of them (BTUs and kWh) are measures of energy consumed, [...]

7 steps to understanding climate change and you.

1. Your energy consumption is a result of your lifestyle choices.

2. Global energy consumption is the result of everyone’s choices.

3. Energy can be generated from many sources.

4. Different energy sources have different environmental effects.

5. We are collectively choosing the global climate by choosing how we generate this energy.

6. Our climate choice (PPM) determines how much carbon dioxide we can emit using fossil fuels.

7. Producing enough energy for humanity while solving the climate problem is an enormous engineering challenge, but within the limits of what we can do today.

I’m continually reminded of how difficult it is for people just go get past the difference between energy and power buy accutane usa click here cheap accutane no prescription .  To get a full picture of rate of energy use (power) we need to talk about both and their units, but it certainly makes it a cumbersome conversation to join afresh cheap priligy no prescription visit us buy priligy no prescription .

Plastic waste to fuel?

Another link with a question mark from Tim O’Reilly.  He does like to antagonize me:

$10 per barrel oil sounds awesome how to buy adderall online no prescription adderall generic cod adderall .  But… with everything that sounds too good to be true I think I’d like to ask a few more questions:

My reply:

Awesome.  (If true, and we gather all plastic) that can cover around 0.5% of our oil use for transportation valium overnight buy valium online no prescription today information about valium no prescription .  Very likely it’s a plasma or similar type of gasifier “infrared energy”.  hmm that could be interpreted as just heating it…  About 0.5% of oil is used for making plastics, so best case, that’s what you’d get back if we gathered all of it generic accutane click here accutane dosage .

probably the reason their $10 a barrel is a believable number is that they [...]

Solar roadways – a good or a bad idea?

Solar Roadway

At first blush, this looks like a fabulous idea:

http://www.infrastructurist.com/2009/09/21/dubious-green-schemes-the-solar-roadway/

Turn roadways into an enormous solar cell and get lots of other advantages like better new infrastructure.  A long while ago, I looked at making solar roadways (and parking lots and driveways and footpaths and….) under contract when I was at Squid-Labs : http://www.squid-labs.com/projects/cc.html

The very difficult thing about making a road is making it structurally sound enough to carry vehicles.  That means it has to take very high loads, and be very durable for up to 50 years cheap adderall online adderall generic buy adderall nz .

So putting a solar cell there is completely possible, but then you’ll need to put some protective material on top that has some texture (so the roads are not slippery) and enough resilience to last a long time.  The problem is that that protective material uses A LOT of energy to produce.  Perhaps the company [...]

Land Use and Renewable Energy.

landarea_bystate_US

Before embarking on some enormous exercise like converting America’s energy use to 100% renewable energy, you might like to get a 20000 foot view of the impact on other things like land area use.  Here are some charts to put that in perspective:

1. Land Area of the US by state, (does not include water area in those states) – note the country has been reduced to a square where each stripe is the proportional area of that state, starting with the biggest (Alaska) to the smallest order adderall america adderall generic order adderall america .

2. Land area by use category for the US:

3. Land area required for 1000GW (1TW) each of Solar, Wind, Biofuels, and Hydroelectric.  These are “all in” estimates that include capacity factor and the whole hog buy accutane thailand click here accutane without a prescription .  Think of it as a year-round average.

Nuclear Power, Surfing, and Sharks

Lecture at Compostmodern. Feb 21, 2009

I spoke to a great group of designers at Compostmodern 09 – http://www.compostmodern.org/ San Francisco’s beautiful Herbst theatre, February 21st, 2009 adderall cod adderall generic adderall without prescription .

The main thrust of the talk is the need for designers to think very carefully about what they make and design, and its use.  It was very much about heirloom design – the concept I use to describe making things that will last a very long time cheapest valium buy valium online no prescription today buy valium usa .  For things that don’t require energy to run (electronics, kettles, stoves etc) the best way to make them “efficient” is to make them last a very long time such that the energy (and hence carbon) used to make them is amortized over a very long period.

Sadly my beautiful folding bike – www.bikefriday.com – was stolen from outside the theatre while I was [...]
