30. I most certainly do understand physics and chemistry and engineering
and most certainly do understand what it takes to extract, let's say, 234Th from seawater.

234Th deficits are routinely used by oceanographers to estimate particulate organic carbon fluxes. 234Th (a daughter of 238U) and is readily adsorbed to particulate organic matter. When these particles sink, they reduce the concentration of 234Th in surface waters. The size of the 234Th deficit is proportional to the rate of particle sinking - which is calibrated using moored or floating sediment trap arrays.

Large submersible electric pumps are used to process thousands of liters of seawater to obtain a few nanograms of 234Th and other radionuclides.

and some of us use cation and anion exchange resins to quantify trace elements in seawater. They don't leave them in seawater for months at a time as microbial biofilms and sessile macroorganisms quickly colonize these materials and render them useless.

And some of us find it funny that anti-renewable types will poo-poo the work of the HSU reseachers and the Utsira hydrogen project ("too small" they say) but in the same breath crow about the *few* grams of 235U that some Japanese researchers "claim" they have isolated from seawater.

Hypocrisy indeed.

Furthermore, Dick Cheney and the massive subsidies in the GOP Energy Bill of 2005 are the ONLY reason any US utility would consider building a new nuclear power plant.

and most of us understand this....and we don't resort to name calling to prove our points...
