		<description>If they succeed in getting this system to  work think how strange things would be. Everything at temperatures over absolute zero emits some black body infrared radiation. In the winter just put some of these magic antennas outside in the snow  and use the power to run an electric space heater in the house.  It would usher in a new world with new physical laws. You would be able to use the same energy over an over, heat to electricity and back to heat after turning a motor or lighting a lamp.



How did they ever get funding for such a boondoggle?</description>

		<description>I bet this array could be made even more useful with a black quartz filter.  The quartz turns UV and some visible light into IR.  If it works, then there would be more IR to absorb.  Now they just need to figure out how to utilize it.</description>

		<description>Efficiency isn&#039;t important; cost is. If you have a device that&#039;s only 10% efficient, but costs 1% as much to make per square meter as a 100% efficient device, you&#039;re in business. The point of the nanoantennas is that they&#039;re

a) potentially WAY cheaper than traditional solar cells per unit area, and

b) better for the environment, since they generally don&#039;t require as many harmful chemicals to manufacture as most photovoltaics.



Incidentally, the infrared antennas are only a stepping stone. There&#039;s a lot of work being done on visible optical antennas as well. The efficiency/cost isn&#039;t there yet, but it will be someday soon.</description>

		<description>Here in the United States there is possibly the greatest wasted solar energy opportunity in the world

if we installed a solar station in death Valley one-mile by 1 mile square would it not produce enough energy to run the entire United States and never have to burn another coal plant again.

For the life of me I do not know why Bill Gates and some of the other billionaires cannot get together and get this done because land is super cheap in death Valley as well as an abundant amount of silken to make the solar panel with so why aren&#039;t the billion-dollar companies investing in this opportunity.</description>

		<description>Oh, Shawn.  You silly, small minded person.



To even suggest that &#039;limiting C02&#039; would &#039;hurt&#039; the economy is totally imaginary. My brother-in-law runs a wind tower manufacturing plant.  My 2nd cousin is going to be an engineer, working on wind and solar energy production.  My B-I-L is currently ADDING to the economy.  My cousin will be doing so after he graduates.



So, to blatantly lie like that instantly makes you part of the problem.  And... whether you like it or not, Peak Oil is real.  The economy is going to hurt after cheap plentiful oil runs out.  Once it does, alternatives will be sought after.



Shawn, who do you think will be making money after Peak Oil?  Well, that would be anyone working in the alternative energy industries.  You won&#039;t be there.  Nope.  Not you.  You&#039;ll still be presenting your imaginary issues and your imagainary scenarios.



You are quite silly.  Quite.</description>

		<description>@Shawn,



Please do a bit of reading before you editorialize and rant about subjects that you clearly don&#039;t understand. Nitrogen is NOT a Greenhouse gas. CO2 and Methane are two of the biggest offenders in the Greenhouse Gas category.



Methane is roughly 20 times more effective at trapping heat in the atmosphere than CO2 is. To truly make an impact on global warming we really need to look at limiting Methane emissions more than CO2. Landfills, rotting biomass, and cattle do more damage to the atmosphere by releasing Methane than all of the automobiles in the world do by emitting CO2.



How do we limit Methane emissions?... Gasification technologies can be used to convert garbage to fuels that can be used to heat buildings and power vehicles. Biomass can be converted to cellulosic Ethanol for cars. I don&#039;t know how you get the cattle to quit farting though... Anyone got any ideas there? GasX maybe?</description>

		<description>Mostly useless.



The correct solution is to use the more expensive solar cells and concentrate light onto them.  I suggest a parabolic aluminum mirror.



That&#039;ll get you from 20% to 35% and come with a total cost of maybe $50/meter.



Want more efficiency?



Use a prism to split the light into colors and then use weird crap like this and you can probably get 80% efficiency on most of frequencies.



Best,

Dan</description>
