Ehrm, in the loop, closed circuit you need impedance definitively (otherwise it would just be an short circuit). But just connecting the other lead? Nothing happens, as nothing is moving! The impedance you say is required is the load, ie. light bulb.
Brushless motors can be already 97-98% efficient. Not much to gain there. But transmitting the power from battery, to ESC (Electronic Speed Controller) and finally to motor can gain quite a bit. Currently in RC cars you use extremely fine and expensive wiring, yet they tend to burn out now and then as amperages have gone beyond 400A peaks...
House wiring will gain some, but 240V is quite a high voltage.
Car wiring will benefit a lot, the losses are very significant at 12V DC.
but most of these will require higher than room temperature superconductors. The last 30-40C increase might be the critical one...
I was wondering wtf is regus... well turns out they have finnish subsidiary too, and they advertise themselves as cost effective x) Office space usually costs here 9€-12€/m2 which includes electricity and some basic services.
Rocket fuels hasn't probably ever been coal and oil based, i very much doubt they ever were. Hydrogen for example can be made with solar energy, and great progress are constantly being made on how to make hydrogen easier and cheaper (=less energy used), just lately someone discovered quite an brilliant and effective way to use microbes for this...
Space elevators: Nanotubes exist, buckyballs exist. The materials are now here, only question remains is to solve the remaining engineering challenges which is mostly just working them out AND ramping up mass production of these exotic materials for cheap enough manufacturing of these materials. Space elevators aren't even the only thing which can get us cheaply there. There was just some weeks ago here on slashdot about a maglev type of rails sending trains in the orbit... Yeah, trains.
Cold fusion is not the only source of vast amounts of energy, albeit it would definitively help. Wireless energy transmission in big, practical scale could make space solar panels and space nuclear reactors a real possibility! Or if we have space elevator, then we can have also electricity transmission via the elevator, and atleast part of it can be superconductive for very low prices if we are lucky (engineering challenge)
It's only a question what we as people want. There hasn't been any great projects taken up by government of this world in decades, if they did we'd have some great progress! Imagine a global team of engineers, with the sophistication of US projects, hands-on grip on sensible and craftmanship of europeans, russian know-how on how to utilize, get standard materials and making things very sturdy, japanese skills of fine electronics and manufacturing techniques, chinese skills of making things economical and to provide a vast workforce... Then even the sky wouldn't be the limit.
Hell, Chinese are constantly taking up major projects, the scale they work on is absolutely stunning! Hell, they start new cities to *this day*. They want something? They get it done, they get it cheap, they get it fast, and it all mostly just works. That being said, a lot of crap comes out of china too, and any chinese person will say the same, but without failure there cannot be success.
That might be the darkside of bitcoin, but it's also being adopted by more and more high tech firms. I've been watching as one by one our competitors start accepting bitcoin as well, we've been accepting it upon request for quite some time now.
Bitcoin hasn't failed, just because there was a bubble it hasn't disappeared anywhere, and adoption just keeps on increasing.
Also, independent chain sponsored by government would actually not work, for one reason being there would be too little hashing power making a 51% attack possible by foreign government, also it would fight against for the things bitcoin stands for. It would make sense for sweden to back bitcoin however, by establishing their own mining farms which can be far smaller than what they would need for their own chain, and sponsoring development on convenient ways to work with it, and establishing exchange rate stability, trading bitcoin on a very small scale on government standards. They could put in just 1million euro to significantly bump the bitcoin value and then use that to stabilize fund to stabilize the price, along with reaping nice profit on the way. That ain't going to happen anytime soon tho, bitcoin is still too small for country level adoption. Tho single country adopting it would quite dramatically change that (and explode bitcoin value)
best advice most of the time is common sense stuff... People just forget the common sense stuff because they don't think about it, and someone has to remind them.
It hasn't costed Visa that much, unless it's overhead costs. Merchants don't get to keep fraudulent payments, VISA gets that money back. So only costs VISA would accrue is on the "overhead" bracket.
Also shitty quality, poor customer service. They are not magic makers neither, it's all based on contention and the fact you are not likely to use anywhere near that kind of bw.
Weight does matter on the acceleration of the bullet. In vacuum you don't have the friction of air, thus accelerating the bullet to extreme speeds is far easier.

I've had a vacation last time in 2010, it was 3 days, including the weekend (=1 day off work). I work even weekends. Often 20hrs a day. But i cannot take vacations.
What i cited was not how i got to live when i was a normal salary working guy, i used to dream of that income level.
That's not 2k € a year in SAVINGS, but the budget for: Health care, clothing, misc expenses, furnishing your apt, hobbies etc etc. That was for higher mid wage income level, quite few gets to enjoy that level of income. I know a lot of people who gross half of that, and even those who consider to having an OK income are getting in some 70% of that only.
2k € a year is *NOTHING*, unless you live very frugally, forget smart phones, forget high quality clothes, forget health care, forget hobbies.
450€ a month of actual buying power is NADA, ZILCH. It might sound like much, but you don't have the high prices we do. A meal at McDonalds costs 11-12€, cheapeast jeans you can find costs 40€, fuel is 1.6€/l. Hell, even a pint of beer costs some 4-5€!
450€ a month is a fortune for someone living in Africa, but in one of the most expensive countries in the world it's nothing. And it's not the cost alone, but the damn taxes which are very high.
LOL! I guess you don't live in Finland. Wages here are tiny, taxes are insane high. In Finland you will know what it means to be POOR. If you have a job you are in worse situation than unemployed people are, and the slightest, smallest, surprise expense can make you efficiently pay for working, unless your salary is VERY high even in capital area terms. The total tax rate for minimum wage is about 60%, if you are educated skill worker earning well tax rate can be 90%, it's just hidden mostly.
From 3k € gross income (which is good here btw), you will retain about 2200€ Apartments costs 800-900€ a month, unless you go for the cheapest which are 500-600€. That sounds great, 1300€ left in hand? Yeah, let's assume you are joe average and have a work travel distance of about 20-25km, so you won't get tax benefits for using your car, but public transportation sucks too bad to use it. 60€ insurance, 150€ a month on gas, and say you do even the minimal maintenance for the car 50€ a mo (Oils, annual inspection, one small repair operation a year, ie. brake pads. Exhaust w/ mufflers will cost more than this budget allows), have an average 7k € car which you are paying 300€ a month. 560€ cost right there just to get to your place of work. 740€ remains. But food costs a lot, you are having "big salary" so you don't want to stay on macaroni diet: 200€ a month at least (Lunch @ work is 6-7€ if employer subsidized) 540€ remains. Phone bill: 40€ Home internet: 40€ Electricity: 30€ a mo (that's quite cheap) 450€ remains.
This 450€ is your buying power, to do your hobbies with, have fun, take your vacations etc. 5400€ a year. After a nice couple weeks vacation in the Caribbean you are left with around 2k € annual buying power. ~167€ a month for your clothing, health care and hobbies. Oh yeah, health care isn't free.
There is a reason why for many Finnish guys/girls even a 20€ cost is too much.
The nature of my job makes me research the situation constantly. Problem is high transit costs in Finland. Cheapest i've found is 1.3€/Mbps as a special deal commitment in a small business budget range, above that HE.net was willing to come to Finland for min. 5Gbps commitment at 10k $ which would be currently 1.52€/Mbps. Goto central Europe and you can get transit at 0.8€/Mbps, and Peering will actually be a huge net benefit. But here in Finland you got to stick mostly with transit.
Transport prices are also high, so you cannot connect to say AMS-IX on the cheap neither because the transport costs takes you to near transit prices.
Still, most Finnish companies are charging around 5-7€/Mbps of transit. Colocation prices are not cheap neither. Many of the DCs i see has huge chillers and do not depend upon outside weather to be cold at all, infact, seems quite to the contrary.
Peering is next to useless in Finland too because of the FICIX peering monopoly, and the only worthwhile peers won't peer with you unless you are ready to pay in total more than transit, ie. Elisa wants you to hook up on all FICIX locations which will bring the cost of exchanged data way too high, seeing that FICIX peering amount is quite low. Also Elisa is nasty to peer with, and the peering will not work properly.
The choice of Transit providers is also very limited compared to Sweden.
Also, if you are on off-net location the costs skyrocket to around 15€/Mbps with 1Gbps commit, even if doesn't require any new fiber to be laid out.
However, new DCs are being build constantly, there was several new majors ones built last year alone, one of which has military spec physical security (old military bunker or something).
The transit prices are not insane high, but they are definitively not competitive. Same goes for electricity.

ehrm, only if you shoot it at too low velocity in a trajectory that gravity will grab it. I would assume the velocity needs to be really small for something weighting as little as a 9mm bullet (7-9gr) and without velocity something that light won't do much damage.
But we would not be left without entertainment, demand is so great new innovative ways to produce to artists to get paid would form. See Iron Sky, biggest budget film ever in Finland's history, and for a great part crowd funded. From the makers of Star Wreck. They are pioneering in this field:)
