here is a better open link
which tells of the Nature nanotechnology article.
What is not clear from the open links is 1 if just dip coating TiO2 Nanoparticles onto an array of Carbon nanotubes might come close to the gains seen. Not likely, but a curious question.
No doubt this is elegant, and among the best results in DSCs seen, plus Belcher hints they might yet do better with further modifications.
This is great idea from MIT researchers. Secrete a extra coating of titanium dioxid by harnessing a virus to lace the anode with nanotubes and incresing the efficiency. How do they think all these !Good work
If we exclude the beer and bread market, how big is the microbial technology segment and how fast will it grow? What is the relevance of this citation, “microbial-based products with a global market value of $156 billion in 2011, that is expected to grow to more than $259 billion by 2016”, which includes the sale of yeast products for beer and presumably bread. Certainly, the dollar amount of yeast sold into beer and bread has absolutely nothing to do with the market growth of microbial solar cells. Yeast was a technical breakthrough for the Babylonians a few thousand years ago, hardly relevant in the context of nanotube solar. If the market research firm needed a plug, at least have them provide a relevant statistic. It would be very interesting to know how close this technology is to being real product and how fast it is projected to grow. Yeast, virus, bread, grow there is a joke in there somewhere.
Drones are, in essence, flying autonomous vehicles. Pros and cons surrounding drones today might well foreshadow the debate over the development of self-driving cars. In the context of a strongly regulated aviation industry, "self-flying" drones pose a fresh challenge. How safe is it to fly drones in different environments? Should drones be required for visual line of sight – as are piloted airplanes? Join EE Times' Junko Yoshida as she moderates a panel of drone experts.
