Diesels have glow plugs; they explosion is caused by the high compression of the fuel air mixture along with the added heat from the plugs. Not spark plugs like in a petrol engine.

Dry moat....much harder to breach then a moat with something you can conveniently swim in or float a boat on.

I have had this exact thing happen; "press F8 when booting to get into safe mode"...."but I just said I'm not running windows, there is no 'safe mode'....what should I do?"...usually results in a confused silence.... :)

I wanted to mod this "funny" but it is too close to the truth....where is the "sad but true" mod!

I'm not sure you know what you are saying...there was plenty of whoosh there!

I suppose that depends on the nature of the trolling; is this a sub-skill of general trolling. Or is is more of a parallel skill to general trolling. I know trolling IRL is a different skill then trolling "on the internet".

I do that with my cell phones; I buy the hardware up front and get a much cheaper plan saving me more then double the original cost of the phone over a two year period. Thus every two years I buy a new phone and am still better off then if I got a subsidized plan and a "free" phone.

To be fair I don't think "butt-reaming" will result in being a father.

We are; after a sheep is all used up we butcher it and send the meat to Australia; pre-marinaded.....old Kiwi reply to lame sheep jokes.

where (rho) is density....

Energy in a moving fluid is 1/2 x (rho) x (area) x (velocity^3); needless to say a wind turbine can be much much larger in area then a water turbine; but the density is a big win here and can easily make up for the lack of area.

You assume that a 1MW generator won't generate 1MW....based on what exactly? If the electrical part of the generator is able to produce 1MW then you size the mechanical parts to supply the required power to spin the generator appropriately.

Yes there are times of dead tide, twice a day for about an hour, which are very predictable. Actual practical efficiencies are another story; how are the mechanical parts of the system going to be fouled, how long it will take etc...

Also your 2/pi number is irrelevant; when a generator is specified it is at RMS; 1MW is 1MW and if you have a perfect electrical machine it is also 1MVA but a practical machine may get max around 950kVA after that the system load will determine the exact power factor and thus the efficiency. In this system the mechanical design is significantly more complex then the electrical side; which is extremely well understood and will be in a sealed box unaffected by the environment.

Disclaimer I work with electrical machines from time to time.

Loosen your watch....I have a pebble; I wear it constantly until it needs a charge (7 - 8 days) then charge for a few hours and put it back on. You need to let it move around a bit just so it gets air under it....no smell; little sweating....easy.

Firing a "beam" of tractors would rip through most targets
