tomWright: So they are using MORE cells, less often, for shorter periods of time? Even if they are more efficient, how much per KWh does this thing cost?Oh, and 20 times the electricity? I though solar cells broke the 6% efficiency barrier years ago. Either I misunderstand that, (possible), or the reporter is misstating something.
TheSwizz: Seems inconvenient. As most solar panels are mounted to the roof, it would take quite a bit of wire and plugs run up to the roof to plug the motors in. I don't see this taking off, unless you could daisy chain the motors together and thus on one power line is necessary.
RatOmeter: Increasing the efficiency of a cell by concentrating more light on it: +Increasing the light concentration heats cell and decreases its base efficiency: -Increasing the cell efficiency by cooling the cells: +Drastically decreasing the overall efficiency (and performance/cost ratio) by adding a shipload more cells and rotating them into and out of the sun to give them a chance to cool: ---
Hardy-r-r: Will they ever recover the energy expended to manufacture the device and all it's components? Sorry about the math.

Just Another OC Homeless Guy: Not sure if serious. Power line OUT.

Monkeyhouse Zendo: It's an interesting idea, charge up the cells and then start hitting them with periodic bursts of focused, high intensity light to get periodict bursts of energy from the device while simultaneously keeping the individual cells cooler. Installs on a flat roof with a smaller footprint so you can get more cells facing the sun and at a more constant incident angle than flat panels. I'm not a fan of moving parts but it would be interesting to see how well prototypes do as well as how low they can get the production costs.
Terrified Asexual Forcemeat: It's not a terrible idea if it works but surely there is a better way to pulse the radiance than spinning the whole unit.
cirby: You want to make a cost-effective home solar system? Make panels that are a convenient, easy to install 1:1 replacement for roofing shingles, and also add on a simple power management system that can tap into a home wiring and battery storage system with minimal installation cost.
namatad: WHY THE FARK would you add batteries??
Honest Bender: Also, the battery array would help shield you from power outages.LOLOLOL, that's why the fark.
cirby: By the way: 95%? Nope.
cirby: two or three percent of homes have active solar systems, you have to start buffering locally.
Quantum Apostrophe: Hardy-r-r: Will they ever recover the energy expended to manufacture the device and all it's components? Sorry about the math.The next generation will be powered by the keystrokes of the extra apostrophes people put into ITS.
namatad: cost of batteries >> than buying when the sun goes down, esp since you are selling your surplus.
Honest Bender: outages?? ROFLwhere do you live Iraq??I live in the real world. Maybe you should pull your head out of your ass and have a look around occasionally.
namatad: 5-10 hour outage, MAYBE ... but two weeks??? HAHAHAHAHAH
Monkeyhouse Zendo: Solyndra's panels of cylindrical cells might present some advantage in that they don't have moving parts but the V3 cone design can use existing flat cells to cover the cone rather than have to develop new manufacturing processes for cylindrical cells.
Dracolich: Anyone else notice the high frequency of internet solar experts? It seems a bit off.
namatad: Force the power company to buy your surplus power back from you at 95% of what they charge you.
namatad: Quantum Apostrophe: Hardy-r-r: Will they ever recover the energy expended to manufacture the device and all it's components? Sorry about the math.The next generation will be powered by the keystrokes of the extra apostrophes people put into ITS.LOLand if you could never recover the energy required to manufacture, then you would never be able to sell the product.The "energy" would be more properly defined as the "cost" to manufacture: materials, people, energy, what not. If that cost has a much greater expense/break even point, it is cheaper to just buy energy directly from the current producers. Early adopters often use new tech JUST to say that they are using new tech, not for a cost savings.Real saving will kick in when all new houses come solar ready or solar pre-installed.Some of the new window solar coatings are interesting. At what point do we just paint/cover all external surfaces? Efficiency is less important if cost and area covered is large enough.
