@MrElmataviejas : Instead of those who own 98 percent of all the land area and 100 percent of all the oil in the middle east, that is, the Muslim Arabs, bitching about Israel, why don't they show their love for their own people and give them a homeland? Oh... they don't have the room? The money? Give me break man... bunch of bullies... they got it all and still have to whine and bitch about tiny Israel which has no room, little land, no oil. So who are the crazy destructive ones?
Wow a news story with music. I guess you don't need a unbiased press when you're gods chosen. Well it's two years on. 70% efficiency would mean this technology would be selling like hot cakes, so I'm going to assume it was not as heroically cool as the music said it was.
@TalksWithDirt It´s a combination of producing electricity (concentrating photovoltaic) and hot water. Both parts together can achieve 70% efficiency without any problems.
But it´s no breakthrough in photovoltaic technology, the electric efficiency may be about 25 percent.
You need cooling for the solar cells. If you can use the hot water from the cooling, you have an additional benefit.
@701983 Okay think about what you are saying. If you are saying that they are converting thermal into electrical power, even gods chosen people suffer from the limitations of thermodynamics. So you're talking about 40 50% efficiency ... IF you run your steam dry. That means over 530 C. If that 530 C is being used as cooling, that means the 'cooled' photovoltaic has to be hotter than 530 C. I'll bet they are praying for this to work, and its not running these years later.
@701983 The only way this could do what you are saying is if they have a use for hot water. Say you want to cool your photovoltaic to 100 C. That means you need to flow a large volume of water at say 75 to 85 C past your heat exchanger. You're talking liters per second for a large array like this. In winter you can use it for heating buildings. But hwo needs THAT much hot water. More likely the waste heat is radiated to space and .,,,. wasted.
@TalksWithDirt Who needs that much hot water? 32 dishes, each of them may produce about 2 kW electricity and 3 kW heat. That would be about 1 MWh heat on a sunny day. Enough energy to get 10 m³ water with 95 C from cold water. Really much hot water, but maybe the kibbuz can use it reasonably.
But you are right: They should not talk about "70 percent efficiency" without further explanation, that´s misleading.
@701983 Right on man, you got it. Only thing is you are off by a factor of 3 on the thermal input of each dish. You're looking at 9 - 15 kw thermal input per dish. Now that said, a farm can sink all that heat. IF the farmers have plumbed all their processes into making use of this waste heat. Which I doubt. I live at the same latitude and let me tell you, you only need to heat buildings a total of 1 month a year. 7/12 ths of the year you need to cool a building.
@701983 Your observations of solar efficiency claims are spot on. We do need solar energy in the world. There is a place for it. But selling it like a used car to an ignorant old lady is not the way to go. We need to roll it out with all the limitations in the public domain so we can adopt it and improve it as we go.
@701983 I would love this kibbutz to show us how cool this system can be. I'll bet it's really cool. Such as ... Here's our communal dish washer steaming our dishes clean. Here's someone taking a hot shower with heated water. Here's our dairy pasturizing milk with solar hot water. Here's our swimming pool heated in Jan and Feb. Here we are steam cleaning the cow pens with solar steam. etc ... I have a feeling this is not happening yet.
I am living in Sachson Antony but it think it will work here also. My Parants have a lot of blue Solar Cells from BP. I have a Solar Trike with blue Solar Cells from Q-Cells and another german factory.
Yeah. That is a very good concept and design. I have been working on something very similar, in my head, for quite a while, as well. This design is much more efficient than the PV Solar applications, for many, if not most, locations. Very nice.

INSTEAD OF DROPPING BOMBS TO THE PALESTINIANS, WHY THE ZIONIST JEWS DON'T CREATE A SOLAR POWER PLANT FOR THEM TOO?

That's great that it's so efficient, but what kind of technology does it use? It looks like it's reflecting light to a boiler like other systems.

I pray that we can have that technology in our country, the Philippines.
That will solve so many problems in environment and cost of energy.
Israel, G_d is really with you.
Long live the G_d of Israel.
