Draft Proposal Would Create Agency To Tax Cars By the Mile

tbischel Re:Fuel Tax Works Fine (932 comments)

What is the difference between this and the already-in-place fuel tax? The fuel tax is even better at metering costs to those that chew up roads (heavy vehicles). This sounds like a solution looking for a cause to me.

while the already in place fuel tax is a fair way to tax vehicles, its possible that a per-mile tax could lead to a more progressive tax structure, where heavy users are disproportionately taxed... similar to the federal income tax structure. Not that I'm a big fan of that...

Italian Scientists Demonstrate Cold Fusion?

tbischel Re:All you need to know, from TFA (815 comments)

On the other hand, if it is a hoax they could write books about it, sell videos online, claim to be suppressed and silenced, then retire.

Google ReCAPTCHA Cracked

tbischel Re:Captcha ZDR .... (211 comments)

All captchas are practically useless. There is no need to crack them - for example decaptcher solves 1000 captchas for $2. Any captcha type works since they're solved by humans.

I bet this type of captcha would still work well on sites like mathoverflow or wolfram...

Software Finds Plagiarism In Research

tbischel Re:plagiarism differs in science vs. English Lit. (111 comments)

"Pick up any math paper on number theory, and you're bound to find the sentence 'Let p be an odd prime number.' without citation, but that would hardly qualify as plagiarism."

I wonder how often you see specifically an odd prime number... since two is the only even prime, its really the oddest of the bunch.

How Should a Non-Techie Learn Programming?

tbischel excel macros for the rookies (346 comments)

I'd say start with something practical that builds on knowledge you may already have. For instance, many people use Excel in their day to day lives... I'd start with the vbscript macros to do simple tasks to make your data more useful.

Company Builds Fast Charging Station For Electric Cars

tbischel Re:Still skeptical about all-electric cars (359 comments)

Here is an interesting study on electric powertrains... it comes to some remarkable conclusions about the wheel to well efficiencies of different technologies, and the long term cost projections... Their analysis seems to point to Battery Electric Vehicles as the least likely long term solution to the transportation section, instead favoring HEVs, PHEVs, and FCVs. Very interesting read!

Company Builds Fast Charging Station For Electric Cars

tbischel Re:I'll wave when I drive past you ... (359 comments)

the Toyota Fuel Cell vehicle gets 420 miles per tank of compressed hydrogen... sounds like they have the storage problem in hand. I agree that combustion hydrogen seems unlikely, but I still have high hopes for FCVs.

Company Builds Fast Charging Station For Electric Cars

tbischel Re:I'll wave when I drive past you ... (359 comments)

Hydrogen will always lose out, because it's simply an energy store and not an energy source. Anyplace we can get hydrogen from? No. We have to convert natural gas to hydrogen (might as well run vehicles on natural gas) or crack H20 into hydrogen with electricity (which is horribly inefficient). Electricity is the end game.

If electric cars were the best solution (or energy efficiency was the only concern), we would be exclusively burn oil in more efficient power plants, and using that to charge batteries in cars... rather than converting crude to gasoline to fill up.

Time To Dump XP?

tbischel Re:XP is the 90's? (1213 comments)

Could have sworn that XP was not available before Windows 2000 -- but what do I know...

Maybe the poster was thinking of "Whistler", which probably did exist in the late 90's...

Cassini's Elaborate Orbital Mechanics

tbischel Re:Algorithms? (116 comments)

well I certainly am not a trajectory analyst or anything, but the guy next to me uses STK to do his analysis (the astrogator plugin). You could be right that they are using Titan to do a swingby, but I've seen some pretty crazy trajectories as a result of unstable orbits around Lagrange points. That is the basis of the space highway.

Cassini's Elaborate Orbital Mechanics

tbischel Re:Algorithms? (116 comments)

They probably are using a tool like this to analyze possible trajectories... these tools do use numerical optimization libraries to pick paths between targets and destinations. Just guessing based on what was said in the summary, they are using the Saturn-Titan Lagrange points to alter their trajectories without using much fuel. You can do some pretty crazy maneuvers around these points.

Senators Blast NASA For Lacking Vision

tbischel Re:Playing to the votors (319 comments)

NASA's budget is less than 0.5% of the federal budget, so arguing cost cutting is a red herring. Entitlement spending expansion without end as the baby boomers retire is the real structural deficit that needs to be addressed. Here is a slightly dated article that explains this a little better. And, as I understand it, they are actually expanding funding for NASA, just taking the plans for an american moon mission off the table, and redirecting that to R&D.

Space Junk Getting Worse

tbischel Re:Push them further away (242 comments)

I think they normally push them into an orbit that will degrade so that they'll burn up on reentry. That takes less energy than putting them on a trajectory that leaves Earth's orbit.

For those lofty orbits in prime real estate (think Geosynchronous), they do push satellites out further into a graveyard orbit. It would take about 1500 m/s deltav to deorbit from way up there, and only a fraction of that to just push it a little further out of the way.

Give Space a Chance, Says Phil Plait

tbischel Re:Yeah, orbit! (279 comments)

They're never going to get us into mars, because there's simply no profit in it.

Oh really? Because to me, Phobos and Deimos (Mars' moons) are little more than a few trillion tons of metal, ceramics, volatiles and a few million tons of precious metals sitting in a nice stable orbit over Mars.

Yeah but shipping charges from Mars are a bitch

Why Counter-Terrorism Is In Shambles

tbischel counterstrike (370 comments)

What does this have to do with my rights online? I'm not a terrorist, so I don't think it effects me.

only n00bs choose to be counter terrorists, cause l33t gamers use the AK. Plus all the maps favor the hostage takers. If this doesn't effect you, I bet you've already been banned as a FC.

FASTRA II Puts 13 GPUs In a Desktop Supercomputer

tbischel GPU accuracy (127 comments)

It used to be that GPUs would sacrifice accuracy for speed in floating point calculations, making them unsuitable for scientific computing. Is this still the case?

Hydrogen fuel cells with non-platinum catalysts

LCROSS finds water

tbischel tbischel writes  |  about 5 years ago

tbischel (862773) writes "The results are in: LCROSS has found "significant amounts" of water on the moon. Many will remember the less than stunning impact a month ago, but the near-infrared spectral signatures indicate water was indeed in the plume created by the satellite's impact in the polar crater. This has long term implications in creating a permanent base on the surface of the moon, allowing astronauts to collect water ice from these craters rather than bringing it from Earth, where water could potentially be used to create propellants, or a tasty moon slushy."

L.A. to Las Vegas MagLev

tbischel tbischel writes  |  more than 6 years ago

tbischel (862773) writes "Plans for a levitating train from Las Vegas to Disneyland can move forward under a transportation bill signed by President Bush on Friday that frees up $45 million for the futuristic project. Derided by critics as pie in the sky, the train would use magnetic levitation technology to carry passengers from Disneyland to Las Vegas in well under two hours, traveling at speeds of up to 300 mph. It would be the first MagLev system in the U.S."
