  1. Hm...Let's change the wording a bit. It's funny how you won't think that climate scientist talking about his own area of expertise is convincing, but a dilettant global warming proponent, with no expertise on the subject whatsoever and caught from serious errors in his program, is. Go figure.
  2. US is not using FT synthesis to make gasoline because - oil companies invested a lot in the technology 30 years ago and it turned out to be unprofitable as oil prices dropped again - it will produce CO2.
  3. In WWII, ethanol would have sense. Coal or wood can be used to provide the energy/heat needed for the distillation. And being a fluid, much easier to transport - and can be used with motors with very little modification. Wood gas engines were a nightmare to operate and maintain. I have some article around that I might be able to get snippets translated from, but until then here's what Wikipedia says about the thing. http://en.wikipedia.org/wiki/Wood_gas However, I think the main issue with the lack of widespread ethanol use in wartime was manpower shortage - and the resulting food shortages.
  4. IIRC a large part of German potato harvest of 1944 ended up being burned up in V2s.
  5. The decision to favor of the Il-76 versus the An-70 can be explained by looking at the country of origin. The first is Russian, the second is not - NIH, anyone?
  6. How much an An-70 costs? It is already flying unlike the A400, its capacity larger, and I suppose also cheaper than the Airbus. NTM that Ukraine is supposed to be a friend, isn't it?
  7. That option is much more appealing for me than stopping to breathe...
  8. I think the example should be provided by Anthropogenic Global Warming advocates. It's just... a matter of principle.
  9. http://www.ncdc.noaa.gov/oa/climate/research/cag3/na.html But Jeff, you should know by now, that Drastical Global Warming Caused by Anthropogenic CO2-Emissions Might Cause Lower Average Temperatures at some Locations. Western Civilization must stop emitting any CO2, better they'd stopped breathing at all. And just to make sure, nuke all coal/oil/NG powerplants in China and India, as they won't stop producing smoke otherwise. The following nucular winter should be able to compensate for about 50% the harmful effect of anthropogenic CO2.
  10. Flaunt your ignorance a bit more please.
  11. How much this complete modernization cost compared to a completely new AFV? 80% the rice?
  12. A considerable part of the problems comes from the insane unjustified speed requirement.
  13. Hungary bought 4 different models from Belarus only. Before that Hungary also had at least 4 or more different iterations for T-72Ms, buying from Poland, Chechoslovakia and DDR. The Hungarian Army and the Red Army forces stationed in Hungary had the task of advancing through Austria and Yugoslavia towards Italy.
  14. Hungary got 4 different models of T-72s back then. Rumors say that they visited the Belarus Armored division, the equipment of which they wanted to buy. The tanks were stacked in coloumns in the storage area. The guy who decided the purchase pointed at two tanks and said we need this two rows. Instead of buying, say, one regiment/brigade worth of tanks of the same type plus engineering vehicles.
  15. They are cutting the number of tanks to 15, saying that we don't need them on halfhearted peacekeeping missions (no combat units etc.). Other nations, who take their peacekeeping commitment seriously, do buy tanks, as they apparently find them very useful in Afghanistan.
  16. Rome's inherent weakness was that it was effectively a city state for most of its history, its political establishment did not change sufficiently to address the changes to survive as an empire. When the City started to decline, it brought the Empire with it. The US of A does not share this weakness.
  17. You beat me to it... Considering that 20 years ago Hungary had 1200 tanks, it dropped two magnitudes in two decades.
  18. The LM one is already over $400m, the newest GD estimate is $350-375m, the latter is referred as the second ship.
  19. Ken, can you suggest any specific book? Preferably English.
  20. Direct Thermal-to-electric conversion usually means thermophotovoltaic effect. Basically fuel (gas, or some liquid) or radioactive decay is used to heat up a radiator piece to very hight temperatures (1000+ C) which then glows hot. The resulting light then converted to energy by solar cells. Efficiencies with spectral filtering and spectrally selective emitters already reached 20%, which is not bad, considering these have only a minimal number of moving parts. The nuclear-fuel version is ideal to spacecrafts. Light, and much more effective than previous nuclear heat sources. Conventional thermoelectric generators using the Seebeck effect are at about at the same 10-20% efficiency.
  21. Well, North Korea, China 2 (it's a long coast), Iran, Venezuela that's 5. So 12-15 CVN?
  22. Tungsten, contary to other information stated elsewhere, still denoted as 'W', standing for Wolfram. 'K' stands for Kalium a.k.a Potassium which would make a very lousy penetrator, being flammable and very soft with an extremely high melting point of 64C (146F).
  23. So SAU pays a mere twice as much as India does?
  24. It is in development, and will have 10% higher performance than COTS (NIH) stuff for 5x the price. Also ready six months before US troops hand the control for most of Iraq over to the local government.
