There were wide scale reports of authorities using chains and locks to seal individual dwellings on apartment buildings by chaining the metal gates closed. If you look at pictures from the field hospitals that they built you'll also no

Where do hospitals get their O2 supply from out of curiosity? Do they buy it from one of the major gas suppliers like praxair or airliquide and store it in the back as GOX/LOX or can it also be produced on site?

Smear some alcohol on your forehead before the check, the phase change as it evaporates will drastically decrease the local temperature where it's applied.

You can also pick up a flightaware dongle, they have extra hardware inside of them that lets you pick up aircraft a bit further out/with more information. Benefit if you pick up one of those normal sdr kits from nooelec is that it come

The 5% is quoted further in the article for overall grid waste. The per mile basis is purely there to compare why higher voltages for the Samer power lead to less waste.

Wait what,holy shit this changes everything. Always thought those were just random manufacturer marks on smt resistors.

Geotech is a bitch. Soils aren't homogenous and vary a lot in both composition and characteristics. There are multiple types of TBMs that are designed to operate under very specific conditions, for example a soft rock/soil TBM exc

I'd add that development is also pretty foolproof since there are charts with precise times and concentrations for every known film and developer combo. There's also stand development which is actually fool proof.

Althought as a Montrealer I am really unhappy that the C-series is now called the A220, I was very happy when Bombardier basically bitch slapped Boeing by getting Airbus to buy it and make it in the US.

Last month China actually started up a district heating system that uses the waste heat from a nuclear reactor.

Heating is actually the biggest user, accounts for 50% of global energy demand. This includes space heating as well as process heat.

Radiation becomes the dominant heat transfer mode in that case though, usually gets really small at day to day temperatures though.

Think the point is that the voltage won't collapse under the load.

Tieing off if you're above 1.8m, not walking under suspended loads and de-energizing systems are so hard drilled into my brain. Haven't been on site in 4 years and I still get triggered by these.

The ground is a poor load and also there's a finite amount of energy you can dump into it because every watt that goes in gets turned into heat, you'd liquify the ground very quickly at the multi MW scale.

The problem with that is getting the batteries to surface. Underground mines operate in either of two access methods: shaft to surface or ramp to surface. In shaft to surface you use an elevator to move all the ore and waste out of the mine

They're 50-80k a tire on a cat797 and the truck has 6. Mine roads aren't the same as normal people roads, top layer can vary between what you see on a gravel road to basically really crap with chunks bigger than your fist. Add on

They have, they're mostly in French though but the language debate in Quebec is a whole other bag of worms...

A counter example would be Quebec's grid which was nationalized in the 40s. Hydro Quebec owns generation, transmission and distribution for the province and provides the lowest residential rates in North America while operating at a pr

Inverters are only used for DC to AC conversion, cogeneration sets are conventional prime mover setups that output 3-phase AC directly. The problem likely has to do with islanded grid stability, without the grid you have to take care of pow

They're more efficient because of reduced frictional losses, the contact point of an elevator is a pulley at the top of shaft and a couple guide rails. The guide rails are mostly there to provide lateral support. As for latency you can

Chinese aviation industry is special, a lot of their airspace is military and is closed to commercial aviation which leads to heavy congestion and thus late arrivals and not a lot of slots. Those high speed trains end up being workhorses fo

Yes, there's a dumb amount of precious metals up there. If you were to bring back the contents of a single asteroid you'd crash the market. Here's a master's thesis on the topic: http://digitool.library.mcgill
