They get the 75% efficiency rating by fermenting beet sugar, burning the resultant alchohol to provide heat, converting the heat into electricity, using the electricity to power a monochromatic light source, which then shines on the PV cell.

All plastics could be made from any organic scrap you have laying around, coal, or from natural gas. It would be more expensive today than using oil cracking sludge, but there are active research programs to reduce this expense.

Iodine is mostly produced from underground brines, waste from the oil industry, and from nitrates in Chile. It is no longer produced from seaweed, and there was never primary production from plain seawater. At the current price of around $10/kg, it would be difficult to extract it economically from seawater (where it occurs at a concentration of 50 ppb.) See http://minerals.er.usgs.gov:80/minerals/pubs/mcs/iodine.txt for the current status of iodine production.

I am not sure exactly what you are saying here. But it would all be clearer if either or both of you included some numbers. Of course, at this point, such numbers would involve enormous uncertainties, but at least we would have something to start talking about.

Yes. I would like those people also to comment. If I understand the proposal correctly, in order to make even a dent of say 10 % drop (of current, not projected levels) would reequire very large scale fertilization of large areas.

As the happy (and quite healthy, I might add) owner of a rather large solar array, I find this whole concept quite humorous. My most "dangerous" ocurrence having happened when I was getting a good, early morning start rewiring and I managed to give myself a rather thorough sunburn... Now granted, I realize from scanning the thread (there's been way too much for me to read it all) that the greater focus is on larger, industrial-sized production and the dangers inherant therein, but one must realize that there's danger in everything - be it falling off a rooftop or scaffold while wiring a solar array or getting irradiated while inspecting a nuclear reactor. What few people realize is something that we in the (leather) Lifestyle have come to recognize as inherant in the world - it is coloquialized by the term "Ulgol's Law" - which simply says that for anything you can think of trying, someone somewhere is already doing or has already tried it and, conversely, anything that you might be a proponent of, someone somewhere is steadfastly against. I'll continue to be quite happy in my solar existance. I clean the panels whenever the rains don't do if for me and in the meantime I'll enjoy the benefits of a nearly effortless and endless supply of virtually free electricity. R.

I simply do not believe your claim. You are saying that there are more poor workers now than in the age of the robber barons, etc? Keep in mind that a huge percentage of the workforce were poor farmers early in this century. There are lots of people who fall in the cracks between welfare and independents. This is an area of concern. However, when you look at the high level of taxation that any working person pays, it is no wonder that many are poor. >Explain why energy prices are up at all, especially when oil in constant >dollars is very low (if not the lowest in history -- it is a point very >often made by economic conservatives).

WHAT erosion? We are attempting to reduce costs of one class of welfare recipients: those who are on welfare. But how about all the farmers and their welfare? We haven't made enough progress there. And the biggest problem in this regard is the elderly. But consider that there are three negative effects to social welfare programs: -they reduce the incentive for working -the put a load on the productive -unless shame is associated with them (as it used to be), they encourage a change to values such as "I have a right to my welfare!" (true quote), and crap like that. No one has figured out how to avoid starving people and yet at the same time not create a bad moral environment.Return to Top

The US DOE is currently funding a small project to explore the addition of cellulase genes to plants (Arabidopsis being the plant chosen for the study, it being the model for plant genetic engineering.) The genes are from thermophilic bacteria, and have low activity at normal temperature. The idea is to grow the plant, harvest it, then heat it up to activate the enzymes. No separate manufacture of enzymes or culture of microorganisms would be needed. Their goal is to provide a cheaper feedstock for ethanol production, but I don't see why it couldn't also be developed for use as a foodstuff. PaulReturn to Top

Much as I dislike agreeing with Yuri (he says so much I guess he must be right occasionally, like a busted analog clock), but, taking world population as a whole the human population was very stable up until about 6000 BC. Introduction of agriculture, you know. It grew slowly but steadily until about 1400, when it started to increase drastically. There was another spurt at 1800 - 1900. Interestingly enough though, and contrary to popluar mythology, the majority of humans who have ever lived are dead. Estimates are from 77 to 80 billion people have lived on Earth, including today's population. See "Popultaion Studies", edited by K. Kammeyer, CHicago, Rand Mcnalley, 1975. which contains an article entitled "How Many People Have Ever Lived on Earth?", by Anabelle Desmond.

Local CA agencies rise and fall with budgets and whims of the governors. I/M programs have come and gone, suceeded and failed. Areas have achieved Ozone attainment status and programs have been dropped. Have more faith in the citizens, they won't fund a program that they don't see a benefit for, Well, not entirely true. I cut apart of your statement about 90% of the reductions have been made that can be made. Your very right about this. The big reductions that were made in the early days are behinds us. To get further reductions from automobiles is going to be very difficult. Diminishing returns on the dollar. One of my early comments was that a new source standard for lawnmowers was the one of the good options for biggest reduction for the dollar. It isn't the PVC valve in terms of reductions of tons for an investment of $10.00, but its has a much higher tons/dollar ratio than a extreme I/M plan. And if we look at the politics/justice issues its a cost being born on the purchasers of new equipment as opposed as a cost on the owner of older vehicles, assumption is that they don't have the ability to pay. So lets get a whole new arguement started. Do any of you all know about the carbon adsorbtion cylinders that are going to be required on all new cars in 98 (? or 99). Its purpose is to capture the vapors displace during refueling, which makes stage two vapour balance system in Cal. and others unneeded. Me, I'm not please at this. If you want to control these VOC's and of course reduce the publics exposure to benzene, why not go to requiring vapour balance system at all gas stations. It does not make sense to me, instead of a moderate cost to the gas station owners (and yes, I know that this cost will be paid eventally by the consumers), the plan is to force the consumer to pay a larger cost for the Carbon sorbers. And you get less of an emission reduction, as the onboard cylindar will only reduce the emissions from new cars. Politics, go figure.

Much of the famine in the last two decades in Africa has been the result of bad politics. Dictator after dictator, war after war. It's not that there isn't enough food in the world to feed these people; it's that it isn't getting to them because of the political situation.

If this is your only "energy" cost, yes. The only concession I'll make is that the initial manufacturing/installation costs of solar panels is not cost effective if you only account for the direct costs of nuclear and coal. If you take into account the cost of the wars we wage, the cost of nuclear waste disposal, the cost of security, etc. etc. I can easily see us paying $20/hour to these solar panel cleaners and still coming out ahead. > William, you are dead wrong on this comment.

Solar 1, however, only generates about 50 MW peak power. Why do you insist on developing Solar 1 plants? Solar one is a poorly engineered solar plant. If you had solar cells on rooftops rather than on dedicated land, you would already have the structural support. And don't give me this BS about rooftops not being able to sustain such loads. > Again, there are numbers that refute your claim.

That is false, my friend. Looking back on what I stated, you are right, I am wrong. Nonetheless, the peak load hours are during the summer, right smack in the middle of the day, when the sun is at its peak. You will have storage requirements, but cadmium is not necessary, because even the load levelers used today in other countries run off lead-acid batteries just fine. If all the nuclear waste is recyclable as you claim it is, why the hell are we burying it in the ground in sealed containers. That sounds more like a land fill than a recycling plant.

Moreover, if you'll re-read what I orignially wrote, I stated that rooftops do not constitute a vast collection area "DEDICATED" to energy collection. Why do you find it so outrageous that homeowners would be willing to pay for someone to clean solar arrays? I won't disagree that the initial cost of manufacturing and putting up solar cells is currently too costly to be a feasible replacement for coal or nuclear- that is if you only consider the direct costs of coal and nuclear and assume that you're paying for the solar array coverage area. However, once up and running, the only maintancence comes down to cleaning the arrays, and I would argue that that is far cheaper than the price of energy today. Suppose it was mandatory that you allow energy companies to put solar cells on your rooftop. These companies wouldn't have to compensate you for doing so, and the startup cost would then be considerably cheaper. Your energy costs would come primarily from cleaning the solar arrays. > > The containment system for a nuclear plant uses far > > more concrete than any equivalent-power producing solar array. > > Wrong.

But solar power *is* safe, because we > think it to be so. Look, I'm not saying that Solar One is a well-engineered solar plant. If you put solar arrays on rooftops, the structural support is already there. You're comparing a system that's been around for some time (nuclear) with a beaurcratic prototype of a system that hasn't even been adopted in this country. There are better ways to go about solar energy collection than Solar One. WilliamReturn to Top

The two are not contradictory: there are now more old folk than ever before.

I doubt that Paul Ehrlich has ever been in Zaire inhis life, and he has certainly had nothing to do with the drop in birth rate there. The main things causing the deline in birth rates are the decline in death rates and the increase in television, cosmetics, and variety in clothing, all of which make people aware of and desirous of modern styles of life. -dlj.Return to Top

People started categorizing stuff: animals by which ones were tame enough to keep, which ones you should kill before they killed you or got away; plants by which ones would grown if you planted them. Arithmetic: how much seed will give us how much food, leaves how much that it's safe to eat now? The agricultural revolution, because it is more knowledge intensive than steam and electric power, ships, trade, or war, is the _last_ of all things to develop. It's happening now, made possible by electron microspcopy and molecular biology, satellite land surveys and hydrology, derivatives-based pricing, and so on. This is why the most advanced countries have agricultural surpluses, and import their manufactured goods from less advanced countries. -dlj.Return to Top

I am currently attempting to model the use of ground (table) water in California by considering its sources of replenishment (precipitation, runoff, etc.) and the various ways in which it is utilized in agriculture, industry, residential areas, etc. I have found a wealth of information regarding the ways in which we use ground water, but have been unable to locate any data on the rate at which our water table is falling, how much water does our annual rainfall contribute, how much water is California estimated to have in its water table, what is the agricultural impact on the water table, is our ground water expected to run out within the next century(ies), etc, etc. I would appreciate any and all information on this topic.

INTERNET Some people prefear to go on thinking that the Einstein’s relativity theory is right , thinking that matter cannot reach and substain light velocity, because in this case matter would have an infinitive mass , and it would be necessary to transfer to it an infinitive quantity of energy to reach light velocity. At the same time the physics substain that at elemental material level the time does not exist and that in normal conditions it is not possible to travel in the time. As opposite to what mentioned before, the writer, after 20 years of research out of the pubblic ufficial circuit of the physical research, can prove that things are different. Some examples of his theories follows: -The conception of time and space given by Einstein Relativity is completly inconsistent applied to the case of light velocity of the matter and the time is translated by some physical, heavy consistent material particles but normally invisible. In many cases the theories substained by the physics are uncomplete or inadeguated to describe the reality, but because of their lack to give an explanation to the real phenomenons; they continue to substain that their concepts is the only truth, thing that is false in the reality. - The Writer gives some information about: 1) travels of matter at light velocity in present time, 2) the explanation of the natural composition of the elemental particles that translate the time in the matter, 3) the explanation of the forces unification, where it is explained the natural formation in the sub-elemental particles of the electricity, of the magnetism and the gravity, 4) explanation of matter at null temperature, where the quarks can be visible and free, because they are stopped in the space, expanded and enlarged 10(18 ) times or 1 billion of billions of times and they are freely visible at naked eyes for about 10 minutes and they reveal their true physical nature as physical particles. The Writer brings explanations and ascertained cases which confutate the Einstein’s relativity theory substaining that the matter can not travel at light velocity. The contrary is possible. It is given the right explanation of the whole physical world (included that the real physical structure of the space is " not "empty" , but it has a completly different structure " normally " not ascertainable "). End of December 1996 it will be ready a book , entitled "THE QUADRIDIMENTIONAL UNIVERSE", where in about 420 pages with colour photos and pictures , the writer explains these theories and many other concepts not already reached by the officials science.
