Carbon Neutral

Climate change is all around
Creeping on us, makes no sound
Always something else to do
The cars, the wars, a bank or two

The answer: easy! has been found!
Leave that carbon in the ground.
Can we resist these fuels so useful?
And live each day carbon neutral?


I think I can, I think I can

Here's an idea. Use electric trains to pull very heavy loads uphill during periods of low electricity use. Then, when you need it, let gravity pull the mass back downhill generating electricity. Will it scale to the power levels actually needed? I dunno, but it's an interesting (and apparently old) idea.

Read about it in the March 25, 2014 issue of Scientific American.


A Better World for nothing.

Joel Pett, a cartoonist with the Lexington-Herald Leader, has brilliantly captured the silliness of opposition to climate friendly policies with the caption:

"What if it's all a hoax and we create a better world for nothing?"

The cartoon itself is widely reproduced on the internet, but I haven't paid the fees to reproduce it here. Still, you should be able to find it at one of these links:


Family Planning 5x more effective at reducing CO2

WHAT’S NEW Robert L. Park Friday, 11 Sep 09 Washington, DC


While the United States is focusing on reduction of greenhouse emissions by
technological means, the Optimum Population Trust in the UK issued a press
release this week comparing the cost of reducing CO2 emissions by
technological means to the cost of an equivalent CO2 reduction by investing
in family planning. It concluded that family planning is five times more



Presentation on Thermoelectrics at Al Gore's Solutions Summit May 1, 2008

The following presentation and manuscript (links below) were prepared at the request of the Office of Honorable Al Gore & Mrs. Tipper Gore for presentation at a 'Solutions Summit' panel on ‘Nanotechnology and New Materials’ held May 1, 2008 in New York City.

The roundtable was chaired by the former Vice President as part of a broader discussion about solutions for the climate crisis.  He believes, and do I, we have only a limited time to solve this planetary emergency.  The discussions themselves were off the record but Mr. Gore is preparing a new solutions-oriented book.  I have opted to make my own contribution public.  It was a rare privilege for me to participate.

Many people in the thermoelectric community graciously contributed ideas and graphics for this effort.  Where I have included citations, please respect the original authors intellectual property rights.  Also keep in mind that those cited need not (and many do not) share my opinions or conclusions on the subject.  But as Robert Park might say, they should.

I am distributing these materials that they may stimulate some discussion and I welcome comments.  The full paper is available below.

Responses are welcome and I will make space available on my website for any reasonable comments.  As always, you can reach me through this website's Contact Form
