Here is my summary of the article: "Powering the planet: Chemical challenges in solar energy utilization"
The authors provide data and their solution to limiting the effects of global warming.
The rate of energy consumption doubles from 13.5 TW in 2001 to 27.6 TW by 2050.
The carbon emissions rate nearly doubles from 6.57 GtC/yr in 2001 to 11.0 GtC/yr by 2050.
The equivalent CO2 emissions rate changes from 24.07 GtCO2/yr in 2001 to 40.3 GtCO2/yr in 2050.
The equivalent CO2 emissions rate produces an atmospheric CO2 concentration above 750 ppm by the end of this century.
An atmospheric CO2 concentration at or above 550 ppm causes a variety of moderate to severe global responses according to some climate models.
A significant contribution of carbon-free power needs to be part of the total energy mix to reduce the atmospheric CO2 concentration.
The authors believe that solar energy has a role if it can be captured, converted, and stored to overcome the drawbacks of the solar resource.
The required energy conversion and storage could be by chemical bonds through production of cheap solar fuels, i.e., artificial photosynthesis.
W~ watt, t~ metric tonne, C~ carbon, CO2~ carbon dioxide, ppm~part per million, G~giga (10^9 power), T~terra (10^12 power)

Continue,
Dave it took me a while to realize this.
This information will give people other related materials to look at here on the site.
It provides some measurable impact of being green.
You want to supply the info, I say keep it coming.
Robert

I second that notion, keep it coming....one suggestion, can you put a link in of the article, book, ect that you might be summarizing. I love this info and the effort. Also, pictures are always welcome, let me know if any of you have problems posting pics or documents on your posts. I have found this platform extremely easy and efficient to use. Robert, can't wait to meet you again in a few weeks I have some really cool stuff to discuss with you and Chris Maenza.

Peter, looking forward to meet you as well at meeting. Rob and I have a lot of ideas and not enough time to get them all done.
Thanks Chris

David,
Was just doing some random research and came across this article, though you might find it interesting....all about being an entreprenuer in the alternative energy/fuels.....

Peter,
Thanks for the information. I found and read the article, and it is useful to me.
Please note that the hyperlink did not function so I had to track it down the hard way. Try clicking on it from this forum to see what I mean. Did it work for you?
