Will A Hybrid Car Really Pay Off?
Greencar takes a look at the economics of owning a hybrid. There will be savings on fuel, but how much? How far will you have to drive to make up for the higher cost of a hybrid?

Tata & MIT System To Use Sunlight To Split Water Into Hydrogen & Oxygen (video)
A criticism often leveled at solar energy is that it is not "base load". i.e. because it only generates electricity in daylight, without storage, it's not available 24/7. Storage is generally expensive &/or inefficient. Numerous schemes have been suggested, but have never reached production apart from for small applications. e.g. lead acid batteries for storage of solar for small communities.
In theory, solar electricity could be used to split water into hydrogen & oxygen. At night, the hydrogen & oxygen could be used directly (e.g. for heating or cooking) or to generate electricity.
In the item below, the system being developed generates hydrogen & oxygen directly from water with greater efficiency than photo voltaic systems.

For better engine efficiency, a different kind of throttle
Limiting the amount of air is the only practical way to throttle an internal combustion engine (ICE). Unfortunately, the throttle in an ICE has long been recognised as a source of ineffciency, due to pumping losses. A more efficient, though expensive, alternative is to control air intake using the valves. Efficiency gains are in the range of 10%.

Worse Than Jail: Sentenced To Life On YouTube
Remember the earlier post, "Laptop Thief's Ridiculous Dance Video Posted By Tech-Savvy Victim"? The story continues:
Important things to consider here:
- The theft wasn't an impulse action, immediately regretted. The thief was happy to make use of his new acquisition to make the (now infamous) video.
- There is no reason to think the laptop would have been returned but for the video.
- There is no reason to think that anyone less tech savvy than the owner of the laptop would have his laptop back, or an apology.
- The thief has returned the laptop & made a statement.
- Legal action may yet be taken by "the detective".
- As of 22:55 GMT Friday 25 March the video is still on YouTube at: http://www.youtube.com/watch?v=8c8W1NDYf38&feature=player_embedded

Safe Atomic Fission Energy From Thorium?
We've heard promises of safe, cheap atomic energy using uranium before, but thorium has a range of advantages, including being much more abundant &, maybe, safer:
http://m.smh.com.au/environment/energy-smart/the-reactor-that-saves-itself-safe-nuclear-does-exist-and--china-leads-the-way-with-thorium-20110323-1c6eb.html
So if thorium has so many advantages, why has humanity persevered with uranium for so long? It has been suggested by many, including the article above, that uranium use has been driven by military interests (in several countries) that want to use uranium (& its daughter element plutonium) for bombs. Notch one more up for thorium.

Apple May Launch Free MobileMe Next Month
One rumor that just won't go away! The "Find My iPhone" component was made free for iPhone 4 with the release of iOS 4.2. Free alternatives are available for all other components of MobileMe, with the added advantage that they don't tie the user to Apple. For calendar, contacts, notes & email, I'm very happy with the Google suite. DropBox & SugarSync provide free cloud storage.

How Secure Does Your Mobile Phone Need To Be?
How much private information do you have stored in your mobile phone? If yours is a basic model, there may just be a few phone numbers. On the other hand, a smart phone will probably have your email, maybe some user IDs & passwords, bank account details? Would you want this information to fall into the hands of someone who finds or steals your phone?
Caveat on the article below: some of the security features described for the iPhone only apply to the latest models. e.g. prior to iOS 4, the only password lock available was a 4 digit PIN. "Find My Phone" is only available free on iPhone 4 with iOS 4.2 or above.
My solution:
- Contact phone number (including offer of a reward) on lock screen;
- Password lock (not just a PIN) that locks a few minutes after the phone is turned off; &
- 1Password app stores logins & other information which requires privacy. It also syncs via Dropbox to my laptop. Versions for iPhone (& iPod Touch), iPad & Android. Free 30 day trial for Macintosh & Windows.

Is It Possible To Build A Disaster-Proof Nuclear Power Plant?
Is it? – Not prior to 1996 according to Gizmodo. The industry that promised "electricity too cheap to meter" in the fifties, safety at Three Mile Island, Windscale (subsequently renamed Sellafield – only the names have been changed to protect the guilty), Chernobyl & until now Fukushima, promises that post 1996 reactors are safe. Anyone else seeing a pattern?

Cold Fusion – Didn't we do this already?
No less a journal than PC PowerPlay (April 2011 edition), reports another "breakthrough" (their quotes) in the field of cold fusion.
To be fair, PC PowerPlay takes a cautious approach, as does this article:

Although there's a bit more enthusiasm at:

I'll wait to see if they get further than Pons & Fleischmann.
