Well stable, the BFL unit is > 4x the hashrate than ztek and more than double ngzhang. Power draw is also more than double ngzhang (Dunno what ztek power draw is). Even allowing for a 10% efficiency decrease for "real world" scenario vs the test data, the numbers still hold.
it means that if i change Icarus's price to less than 350$ than BFL's life is over?

there must be soming misunderstanding here, i mean some other product(my me or other) reach <1$/M, not Icarus. sorry.
