Solar Nanotubes Make Light Work?
I have been reporting on developments in photovoltaic cells for as long as I can remember and there’s always some new technology or fabrication method that’s going to improve upon the woeful efficiency of today’s silicon based solar cells. I’m still waiting and outside the labs most commercial cells still only manage a fairly miserable 20 – 30 percent efficiency, which basically means that during their lifetime very few solar cells ever recover the enormous amount of energy put into their manufacture, let alone live long enough to generate ‘free’ electricity. I have no doubt that one day the problem will be licked and this might just be the development to do it. It’s a rolled up graphene layer nanotube and it’s the brainchild of a team of researchers at Cornell University. The first problem, though, is that it’s tiny, no larger than a DNA molecule, which means you’ll need an awful lot of them to do anything useful. The good news is that it’s very efficient and when exposed to light the tubular structure creates more electrons, and the cylindrical structure makes it easier for them to flow. I know, we’ve been here before so don’t hold your breath, but one day, it will happen, and maybe, just maybe this is where it started…

Description from Google, but …
Google announced yesterday lived and here we have a problem, all the sites listed in search results led to malicious sites were shown in the category. This problem enough damage to a web site has on it an attack description added.
Google, the official blog, the first statement, that they work together to identify malicious sites and non-profit StopBadware.org site occurs because of the announced list. StopBadware.org is that with their own blog pages, this claim was rejected. Summarized in the following definition was told: “Google’s problem is causing us to list the claim is false. Google the list of sites that identify themselves, and this list we know that has nothing to do. With Google, a new description to do is to call.” Read more
New AVG Annoyance
It’s hard to get too upset with AVG, after all they have been providing us with top-notch virus protection for free these last few years, but the release of AVG version 8 has annoyed a lot of otherwise loyal users. Over the last few weeks popups have been appearing that appear to suggest that AVG was no longer free and to stay protected you had to upgrade to a paid-for version. The fact is AVG 8 is still free for personal use, but of course AVG would rather you purchased the better-specified commercial version – well, you can’t blame them for trying. For the record the free version can be downloaded from http://free.avg.com
The latest problem is a component in AVG 8, called Link Scanner, which has been driving some website owners potty. The idea is when you do a web search it pre-checks all of the links, looking for malicious sites. The trouble is websites get bombarded with fake hits from PCs running AVG 8, clogging up the web with pointless and wasteful traffic. Some users also suggest that the Link Scanners slows their PC down, which could well be the case on older machines. Read more

Here’s a solution looking for a problem. Let’s suppose you have a quantity of images that you want to crop and resize in a hurry, and at the same time, convert them from one image file format to another (jpeg, png, gif or tiff), and while you are at it, you also want to add a time/date stamp and a copyright watermark.
We’ve all been there and usually the only way to do it is one at a time, using an image editing program, well not any more! All you need is iKnow Batch Crop, and that’s really all you need to know. It’s incredibly easy; there are just three simple steps. Step One asks you to create a folder to store your modified pix in.

Mac Owners Told ‘Don’t Panic’
Security specialists Sophos are doing a fine impression of Dad’s Army’s Corporal Jones with its latest advice to Apple Mac users, which is ‘Don’t Panic’. This follows the discovery of a Trojan horse web popup that targets OS X users, called Troj/MacSwp-B or ‘Imunizator’. Windows PC owners will be familiar with the trick it plays, it purports to be a security program checking for problems, which needless to say it finds, it then tries to frighten Mac users into paying out for bogus software.
