    A human would die in two minutes on mars. oh, you mean with TONS of supplies send humans? forget it, robots win.

    The energy requirements alone of a human compared to the robot are fearsome.

    no, you are wrong. A scientist or engineer (I am engineering physicist, both) would say exactly what I did, there are no time units to add, watt-seconds per second = watt.

    you're confused, 500 watt-seconds per second *IS* 500 watts. so is 500 watts-fortnights per fortnight (it's called dimensional analysis, you fail it)

    I said 1 kilogram of pu-228 generates 500 watts. there is nothing more to add, no other units need be introduced, that's the *power* generated by 1 Kg of Pu-228. nuclear engineer here, been doing this shit for a long time.

    should point out that 85% is by very nature of the "kinetic energy" of fission fragments you are talking about, they only travel a microscopic distance in a fuel pellet before being turned into heat. Most of the remaining 15% is gamma ray energy. you could convert all of that into electricity by unknown process, and still be mostly limited by heat engine efficiency for the 85%.

    nuclear engineer here: nonsense, 85% of the energy of fission is released as heat energy. you are going to convert heat to electricity, without a heat engine?

    the company oDesk is doing it to its contractors, apparently their services have been used by the named companies (Google, HP, and NBC).

    Different than those companies doing it directly, as likely most of their contractors have no such spy system in place. However, maybe you or others would refuse to work for a company that does any business with oDesk (and can find that out) .

    but with light there is fundamental known truth. It always is quantized, made of discrete chunks of energy. there is no alternative possible view to that. It is the first known quantum phenomenon. Anything involving light must have quantum (discrete) creation, transmission, absorption of energy.

    Sorry, but in this universe we have to obey the laws of thermodynamics. There are no 100% efficient electric power generation systems. The efficiency of a real world wind turbine can't be more than 30%. A heat engine (including steam turbine systems or using solar to heat working fluid) can't be more efficient than carnot efficiency limit, less than 42% for real world plants. Direct solar conversion to electricity can't be more than 34% efficient.

    no. but the usual Pu-239 isn't very radioactive, just emits alphas slowly with a very long half life of 24,200 years. That radiation can't even penetrate your skin or go through a piece of paper. Pu-240 is artificial, usually decays by alpha but sometimes spontaneously fissions, it too has long half-life of more than 6500 years. Then there is Pu-238, emits huge amounts of alphas with its short half-life of 88 years, it's used in RTG batteries and also radioisotope heater units. A kilogram of the stuff gives off 500 watts.

    If proper expandable solution for the present situation, projected growth and strategic plan were purchased, later unexpected purchases would only be necessitated by something unforeseen, whether growth or changes to business methods or direction. Management just needs to be made aware. If they think most businesses future IT needs can be seen absolutely accurately 5 or 10 years later, they are fools. For example, in 2004, would certain major U.S. banks know that the Blackberry (or similar) and server infrastructure for it would be a core IT tool in their business five to ten years later?
