Comment Re:How does powerwall beat lead-acid? (Score 1) 231

Your calculations are off by over a factor of 4 because just as the Tesla batteries don't use their full capacity to maintain their 10 year life (they are really 20 KWh batteries used fractionally to produce 14 Kh) lead acid batteries only last if you use less than 50% of their capacity each day, and then they may last 5 years.

So you will need to buy at least 28KWh of lead acid X 2 to equal 1 Tesla Power wall for a total lead acid cost of $5600 plus the cost of battery chargers, and monthly maintenance (topping off the water, etc.) to equal one $5000 leased, maintenance free Powerwall, and have a ventilated place in your house to keep the 28 monster batteries and associated power management boxes and cables.

I recently tried to use LO 5.1 professionally editing MS Office docs. Unfortunately, these documents had many imported diagrams.

ANY document that contained MS Office drawings failed importing miserably. I ended up needed to export each editable drawing in the Word document and convert it to a PNG image and import it. It was the only way I found to keep from screwing up the diagrams in the Word documents.

So unless LO 5.2 fixed working with Office drawings, forget compatibility.

Still have a Hi-8 Betamax camera that we use as a player and about a few dozen cassettes of videos, mostly of our baby, plus a shelf of VHS cassettes and a VHS recorder. That baby is almost 20 now.
We plug the camera into our top rated (in 1995) 32" Sony Trinitron TV, which still works great. We will get one of those new-fangled HD flat screens one of these days, I suppose. :)

By the way, can anyone recommend a Hi-8 digitizing service?

Why all the GPL hate speech? Any ol' proprietary program can use this free FLIF code by keeping their proprietary code as a separate executable that communicates to the FLIF codec through an open interface. Note that many applications today consist of multiple processes that communicate with each other.

how exactly can it "revolutionize disaster relief" when it needs an almost 40km^2 (6-8km in diameter) receiver array on the ground to get the power beamed from the satellite. Disaster relief means fast deployment. How fast can you deploy a 40km^2 grid on the ground?

Well, you could use the microwaves to warm everybody up nicely. :-)


Submission + - Microsoft patents smart glasses with augmented reality (

another random user writes: A patent granted to the US tech firm describes how the eyewear could be used to bring up statistics over a wearer's view of a baseball game or details of characters in a play.

The newly-released document was filed in May 2011 and is highly detailed. If a product comes to market it could challenge Google's Project Glass.

Google is planning to deliver its augmented reality glasses to developers early next year and then follow with a release to consumers in 2014. Smaller firms — such as Vuzix, TTP and Explore Engage — are also working on rival systems.

Although some have questioned how many people would want to wear such devices, a recent report by Juniper Research indicated that the market for smart glasses and other next-generation wearable tech could be worth $1.5bn by 2014 and would multiply over following years.

6 Homeless People Saved By the Internet 94

An anonymous reader writes "With Ted Williams's story (the homeless man with the golden voice, saved by the internet) blowing up online, and in the traditional media, we figured it was time to tell the stories of 5 other homeless people who've found success, be it financial or personal, through the wonderful use of this series of tubes we call The Internet."

DIY FireHero Project 27

If you have a propane tank, an ultrasonic sensor, a copy of Guitar Hero and a touch of pyromania, this is the project for you. From the article: "For version 1 of FireHero, the player simply watches a video of the guitar hero chart and plays on the guitar accordingly. Version 2 of FireHero will have a much better system, with Autoplay functionality. I will be able to take a custom guitar hero chart, convert it into a MIDI file, and use Processing to analyze it and play FireHero to the track."
