Oh, I forgot to give some He vs H2 figures, I'll just float around... There isn't really a lot of difference in the H2 vs He lift, I think He is 3% heavier. One cubic meter of He will lift 970grams.
He would probably be a better source of lift for balloons/blimps if it was cheaper and easier to make and avialable to every one. But since the only He mine is in the USoA, then it would figure that they would have He airships.
Correct, except for the fact that airships use He and not H2 nowadays, avoiding the whole "oops, big explosion"
problem.
That's right, I keep forgetting that some people seen to believe gasoline is safe the H2. The "oops, big explosion" you're refering to has nothing to do with H2 but more to do with the
metallic (rocket fuel like) coating that was
put on the airship skin. H2 is renewable, He is not renewable...
Btw, the reason that H2 is safe than gasoline is before H2 will raise up and escape, where as gasoline fumes will sink and pool in nice easy
to explode pockets. Let's count the number of
gasoline explosion compared to H2 explosions
that have resulted in loss of life....
If was going to build one of these puppies, I'd fill it with H2. Remember, more than 80% of people on the hindenburg escaped without injury, can that be said of any of todays aircraft? Gee, these days if something goes wrong on an aircraft in flight, even if it's just taken off you are almost sure to get 100% fatality rate....
Is it just me, or does any one else think
this is too small to be a heavy carrier?
1 cubic meter of H2 will lift 1kg. At 300x600x40 feet, this could carry almost 3 T-90 tank (45-50,000kg each). Maybe this is a lot, but doesn't seem like to me...
Yeah, that's right, they release another star wars thing, I remember ep1, but I thought we where still waiting ep2 to come out. But come to think about it, I've seen ep2... hmmmm, it's beer:30.
Sure sounds like it... so how big does a plane
need to be to deliver an antimatter device?
Once containment problems have been solved
antimatter missles wouldn't have to be very big
to deliver a.5 gram pay load.
How much damage would.5 grams of antimatter
do anyway?
I think the problem is is that there isnt enough land for the amount of ppl that would use this.
How much land are we missing?
COuld you imagine how much Vegetables would be needed if everyone in america drove these type cars.
Let's see, palm oil produces 350 gallons of veggie oil per acre, per harvest.
If you drive 14,000 miles per year and get 20 miles to the gallon (probably more, even 50mpg
with a nice small diesel car), this works out
to one harvest a year for two acres. Not very
much really.
And thats just America.
In some regards America is a lonely
country. Travel more, then you'll see how
succesful biodiesel/fuels are in other countries.
And plants
are a renewable resource but they take time to grow
Right.... and how long does it take for fossil fuels to form... A lot longer than biofuel.
You could shake your fossil fuel habbit in a couple
of years, easy...
Yes but each XBox purchased is another tally to the install base to tought to potential developers. Look guys, we sold 10
million XBoxes, thats 10 million potential customers for your deer fucker, er, hunter game.
This guy is right, if you buy an XBox and
endup giving up because it's really hard to
get linux working, make sure you smash the mainboard and stop anybody for getting ideas
like buying video games and running them on
the XBox, or it will be making money
for MicroSoft!!!!!
except I don't really consider sites like Slashdot as "hard news" sites, which MSNBC is (generally) supposed to be.
Sorry, but I don't really consider a Micro$oft
marketing subdivision as "hard news" site.
;-)
VA and Red Hat have both bought news sites to make themselves look good (on come, what they bought it to help to community?), of course, neither VA or Red Hat did it to national news source. MS is only slight less scary than Bush's "Office of controlling public opinon", BTW did anybody really believe the press release about this department being shut down?
The good programmers (which admittedly aren't ALL programmers) didn't so much get sloppy as they stopped
sweating the small details.
I guess it depends on your definition of "good programmers". Things like "stop sweating the
small details" are the number one reason that
open source projects have so many endian problems.
Of course, on embedded systems you often have to have the small & simple mindset that was around when 64K of
memory was a huge amount on any system...But trying to extend that to saying people who program so-called
"bloatware" for PC level systems are bad programmers is completely wrong.
"If an accountant buys an object for $2000, which
he could have gotten for $64 if he'd taken the
right approach, would that make him a bad accountant?"
I guess it's a trick question, because he'd only be a "bad accountant" if he goes over budget, of course I wouldn't call him a good accountant either. This could apply to programmers as well...
You know, the problem with programmers these days is that they don't know their born. Generally, once computers got more than 64K (some claim
this figure is lower) of memory, programming styles got slopply.
If IBM can fit Linux and X Windowing System into a 8meg watch, then You can fit linux onto almost anything. I don't
see the point of having several thousand man hours used to develop an embeded OS that uses >100K of memory when
you can use linux and just buy a slightly bigger memory chip.
Things aren't that simple, so now that you've
increased the memory requirement of the device
by 80x, where will you put the battery that has
to be 80x bigger (or more) to last the same
amount of time? Why bother having laptops
when we've got desktops?
Why bother making car more efficient when
we can just drill more oil wells?
Sub 100K OSs are a really dream come true for
a lot of embedded device developers. BTW, for
many embedded systems developers 100K is a lot
of memory, many are working on devices in 2K
to 16K range....
I'm sad to see eCos go, it's a great idea.
When Red Hat talk about embedded systems
they mean the people they got from buying
Cygnus.
If find it amazing how hard Red Hat seem
to find the embedded systems industry.
Cygnus where around since 1989 providing
Open source support for the embedded systems
industry. They still have Cygwin...
We need another cool Open source embedded
support company to take up the void left by Cygnus...
I don't have a Windows box, but I think cron on Windows is called "after".
You could write something simple in Tcl and run it with "after". If the after time expires while the
computer is off, I believe the after command will be ran first thing on startup.... I could be wrong so if you care that much look it up....
Plenty of Tcl mailer libraries and stuff like that.
You wouldn't want your house to be lit by current LED technology. They have a much narrower spectrum of light than
any commonly used bulb technology - sort of the opposite of the "natural light" bulbs that some companies sell.
Lots of people seem to think that for some reason. But it's the other way round (of course I'm assuming your not comparing blue LEDs to the Sun color). LEDs can provide a very pure white light, while the 'white' light the sun provides is in fact skewed towards the red side of the spectrum. LEDs are popular for caving head lamps for a number of reason, but to start off with a lot
of people didn't like the light because it's too blue and cold (of course it's not blue, but because we are used to the red/orange of sun light
white will look blue). In the end, cavers started to put a couple of orange or red LEDs in with the
white one to skew the spectrum to mimic the sun's light.
So, bottom line, it's the Sun's spectrum that is 'poor' and 'narrower'.... we're just used to it and like it that way.
Regarding the brakes and wear regarding the increased weight from the batteries. In the Toyota Prius, it's 110 lbs. The 1.5 Liter engine with
the generator/starter and motor/generator and battery is about the same weight as the V6 engine it replaces.
This might be true of factory hybrids, but if you want a pure electric converted from $300 car with a blown out engine, then you find that weight saved from the removal for the ICE, exaust system, fuel tank (and fuel), isn't going to off set the weight of enought deep cycle batteries to give you a nice range...
Check out the before and after curb weights at evalbum.com.
too bad the oil companies will do all they can to keep those kinds of cars from selling, hurts their profits you know
Well, the auto companies (well, really the auto industry) stand to have a more
damaged profit margin than the oil companies do.
An ICE (internal combuston Engine) based car cost
28cent per mile to run (about 6cent of that goes
to gas, the rest is spend on brakes, oil changes
and replacement parts and repairs), and electric car cost about 6 cents per mile run, around half of this is spend on charging the batteries, the
rest is spent on new motor brushs (At 80k miles) and replacing all the batteries after 4 or 5 years (also brakes, which may wear less if you have regenerative braking, or may wear more because the car has to be heavier due the wieght of batteries.
I think that everybody in a household should have an electric car for driving around town...
Hell, guys in places like Thailand survive off the used
tabacco industry-- the process of picking the leftover tabacco out of peoples used buds and reconstituting them into
"recycled" cigarettes.
Buds? great, I would be up for picking the leftovers out of peoples buds...;)
Even though you specifically mention that you provide ventilation, I bet you will still get people yapping at you that your
setup is dangerous because of the hydrogen:-)
To a large extent the danger of explosion can be reduced by using
hydrogen catalyst battery caps on all cells of the lead acid battery.
These can be purchased from Hydrocap, 975 N.W. 95 Street, Miami Florida,
33150,(305)696-2504.

It would seem, depending on how much you want to spend you can make a snail or draggester as far as electric cars go... it's all about money...

I'd like to see a used car dealership that buys ICE cars with blown motors and converts them to electric, every town should have one....
they where not trying to rip off either Lotus Elise or the Electric Tropica ......
Probably not, you can use readxa to copy the mpeg-1 files off the vcd and then ftp them where ever you want....

Hmmm, I don't think that they where really geeks, management is where you put people who have proven that they can't do technical work.
Besides, real geeks would turn down the offer.
I think managers are dirtier than engineers, they where clean suits and shoes, but I've found the hygiene habbits of managers to be grim at best.
Is just by company or are other people making the same observations???
almost... the seem to keep the MPGs on a seperate
