Record Setting 500 Trillion-Watt Laser Shot Achieved

rvaniwaa Re:One Thousand Times (252 comments)

Actually, the lasers use a very low wattage generator of the like you can get at Radio Shack. This impulse is them amplified by successively sending the pulse through amplifiers until the final 500+TW is achieved. --Ron

Retailer Calls Rivals' Bluff On "HDMI Scam"

rvaniwaa Re:This one wins the prize (664 comments)

Even funnier, it says "Additionally, signal directional markings are provided for optimum signal transfer". A close up picture of the plug shows a double ended arrow.... --Ron

King's Dark Tower Series To Be Adapted For Film, TV

rvaniwaa Excited and scared (238 comments)

The Dark Tower series is my all time favorite series of books and I have read them all multiple times. I worry about how it will adapt to both the big and little screen although the adaption of The Stand did fairly well. It is a huge story and I love it all (except for the last half of the last book).

Just What is this ASUS Eee Thing Anyway?

rvaniwaa 10" Screen PLEASE!!! (401 comments)

I want one but a 7" screen is just a bit too small. I would drop my money in a second if they put out one with a 10" screen. Asus said they would months ago and then retracted the statement. The small screen size is the only thing holding me back right now... --Ron

Liquid fuel using cerium, powered by light

rvaniwaa rvaniwaa writes  |  more than 3 years ago

rvaniwaa (136502) writes "Here is yet another technique in the lab that is generating fuel from light. This new technique uses cerium (58 on the periodic table) to power a reaction in carbon dioxide and water. Cerium is nearly as abundent as copper in the crust so it does not strongly limit the technology like other less common elements like platinum. The reaction requires very high temperatures (1600C) and is currently only about1% effective at turning photons into fuel. If we keep looking, perhaps one of these technologies will pan out and put fuel in my car!"
