Welcome to the Energy Blog


  • The Energy Blog is where all topics relating to The Energy Revolution are presented. Increasingly, expensive oil, coal and global warming are causing an energy revolution by requiring fossil fuels to be supplemented by alternative energy sources and by requiring changes in lifestyle.

Carbon Nanotubes are still extremely expensive, £1000 per gram the last time I checked.

Very misleading article title, like so many others. If you read the article you will see several statements such as "a cheap and potentially simpler alternative" pay close attention to the word 'potentially' as this is nowhere near developed for commercialization or even lab samples.

Also "Imagine some day", and "Someday, I hope to see this process become an inexpensive energy alternative"

So really the title should have been something like "Researchers Develop New Configuration for Potential Future Nanotube-based Solar Cells".

What about what NanoSolar is doing in Palo Alto?

I too think that the information provided in the article is rather confusing.

"Someday homeowners will even be able to print sheets of these solar cells with inexpensive home-based inkjet printers.”

“Imagine some day driving in your hybrid car with a solar panel painted on the roof, which is producing electricity to drive the engine."

These two statements make me wonder about these guys. Why would it possibly make more economic sense to print the solar sheets on a home printer rather than in a high-volume industrial setting?

And it seems unlikely that solar panels on car roofs would generate a high enough proportion of the total energy consumed to be worth the bother.

Slashdot had a link to this paper. I really didn't understand it. I did see the sentence in the introduction: "The relatively low power conversion efficiency (0.04%) of the device ..."

It could take a while to get it to the point that it is commercailly useful.

New tandem organic solar cells seem like a better bet. One of its developers is talking big.

"It takes 2 U.S. dollars to generate one watt of electric power if you use silicon solar cells," explained Professor Lee, "Only ten U.S. cents [would be required] to generate 1 watt if you use this tandem polymer solar cell," said Lee. The use of inexpensive plastics is a key to cut down the cost for its fabrication. They expect to reach the market in 3-5 years.

Carbon nanotube production is ramping up and will be 5,000 to 10,000 tons is 2011 up from about 60 tons last year. Prices should fall 5 to 50 times over the next 4 years. From $200/kg down to $4-40/kg. Prices vary based on the type of carbon nanotube.

"The key is using inexpensive plastics ..."

They mean oil ?

I've been reading this geewhiz stuff for close to 40 years and it's still not practical. It's always soon, next year....but never available now. I'm 68. Will I live to see it?

your process is not more effective dear, it may be if you draw the diagram of its manufacturing as well as all name of devices..some time peoples try it so it may be danger for the human being...thanks good information ....

I did encountered something like it before.

 solar panel

very good blog, thanks a lot. Solar panels provide clean and renewable energy. I use one, and I'm really happy with it.
I hope that you will continue sharing your knowledge with us.

One thing I know about solar panel is that solar panels not only save money on electricity bills, but also provide a boost to home owners at resale. Other thing these provide clean environment.
