yes, 4% but scaled up 4million per cent so you can actually see the buggers on that scale.

funny thing about that, this year is the first year i've actually drove around a significant amount int th weather that seems to grind britain to a halt. and what i've found is, it really isn't that bad at all and most of the roads i've been driving on are backroads that haven't seen grit since they were dirt paths(a few still are). the only problem i had was in a carpark with a very slight incline, i would get half way up, wheel spin and slide back down, a little run up sorted that out. the mind boggles about how the rest of people find it difficult to drive in such conditions, perhaps we should have a section of the road test done on a skid pan.

everybody should be afraid when i'm onto something

this may just be due to me being a chemical engineer but i think you would be better going for the fluidized bed approach to this, have a steady stream of air injected at the bottom of the bed and in a certain velocity range it will fluidize giving the same effect as agitation by vibrations.

iNow beat me to it.

well, obviously the hydrate of the complex is red and the anhydrate is white. in the dessicatior the water is removed turning the red hydrate into the white anhydrate. when washing the crucible water was reintriduced and the hydrate was fromed again.

mooeypoo for one, go check out her vids on her blog. geek godess if there ever was one.

yeah, chemical engineering in particular gotta love it.

1/ don't call it HHO, HHO doesn't exist and is some crackpots idiotic scam to make money. you are electrolysing water to get hydrogen and oxygen. 2/ use distilled water and sodium hydroxide for the electrolyte, using sea salt or table salt will produce chlorine which is bad and will likely corrode your electrodes forming the sludge. 3/ if you see any site/video/whatever mentioning magnecules steer clear of it, it isn't scientific and it is wrong.

Come on chemistry! WOO!(or should i say tungsten dioxide?)

yes, the earth can cool, as it there is insignificant mass transfer onto or off of the earth this means it can only cool radiatively. this typically happens on the night side of earth, lighting this up or even just increasing the light to the day side wil increase the equilibrium temperature and on this scale it will increase it dramatically. in a few years the global average temperature could be up around 50*C.

At the risk of sounding incredibly nerdy, how about because it's fun. i love learning about new things. Today for instance I learned a good deal about MOFs(Metal Organic Frameworks) used to store CO2. quite an interesting technology and relevant to the project i'm working on(hence the reason i came across it).

i've heard that english is hard, with all the stuff like 'there their they're' and so on. not to mention read and read, lead and lead and nobody really knows whats going on with cabbage, weirdest word we have. i suppose glaswegian could be considered harder as although it is engilsh(of a sort) it is best pronounced when you are too drunk to stand up let alone remember what your supposed to be saying. although i suppose by then the 'drunk interpretation' reflex comes in and you can instantly understand anybody in any language. then again, the usually translates everything to 'fancy a kebab?' and 'more drinks please'

they wouldn't agree on the relativistic mass but all would be right. relativistic mass is as its name suggests relative. same way they won't agree on the speed the object is travelling but they will all be right.

nope, energy isn't destroyed either. in the case of the rocket and the concrete wall, the energy goes into the heat, sound, breaking the concrete up(will eventually become heat) and the kinetic energy of the resultant debris. in the case of the photon, it will carry on eternally until it hits something.

more to the point, how can we afford the energy expenditure when we are in an energy crisis? not to mention the fact that if we increase the energy influx from the sun then global warming will skyrocket. and we're not talking a few degrees C but several tens.

if the physical constants were different enough so life couldn't form then we wouldn't be here to contemplate it. so, by necessity, if life requires certain bounds on physical constants to arise then we will only appear if the universe has those physical constants. as we are here, the universe should have physical constants favourable to earth and surprise surprise this is what we observe.

it helps simulate working in a weightless environment as they can float around easily in the tank while setting up some sort of rigging to do that in the air would be extremely complex costly and wouldn't work as well. its not a perfect simulation, but according to the astronauts themselves its actually rather good.

Airbrush, i think you should know that jeff here tends not to agree with modern cosmology, even the observations. iirc he believe that all the galaxies are in orbit of some point but he's not sure where it is or how to find it.

So, as i've been practically living in the library for the past two weeks(i'm typing this in the library just now) i decided that i would venture down to the canteen and see what they have(gotta be better than the sandwiches i make from whatever's in the fridge, corned beef tuna and coleslaw isn't as good as it looked). well, my finds were that i'm not actually sure what they're selling. the only sandwich that didn't have some pretentous french name was 'bree and pickle' which according to wikipedia is a kind of cheese. being adventerous i picked a random one the looked as if it had a nice and chunky filling and hoped for the best(nearest shop where i can get a decent sandwich is about half a mile away). dear god was that a mistake. it looked chunky but it was actually just gooey. it also tasted an awful lot like athletes foot. So, its quarter to three, my mouth tastes like i've been liking the feet of the track and field team (although the vodka i smuggled in is helping with that) and i'm still hungry. if anyone's in glasgow, do you mind nipping into greggs and getting me a scotch pie or a bridie?

either electric or magnetic field, it doesn't really matter.

okay, well for one hydrogen production is governed by the economies of scale. it would be better(cheaper) to have a few massive hydrogen production facilities than to havea few thousand smaller ones dotted about. not only that but the strain on the grid carrying electricity to the filling stations would currently take it far over capacity, thus the infrastructure would need to be replaced. not only that but new power plants would need to be made, lots of them. while if you were building centralized hydrogen plants then you would just need one power plant per hydrogen plant. and obviously these can't be fossil fuel plants. i'm a fan of nuclear for this.

for once i agree with you, it was going so well until kyrisch 'the buzzkiller' stepped in.

the infrastucture is all the plants and transport system required to distribute the hydrogen. look at petrol just now, massive tankers, refineries, filling stations, pipelines and so on. you'd need to replace pretty much all of that for hydrogen to be distributed effectively.

yeah, even though there are some things that can never be achieved, those that can tend to be FAR more interesting.
