Rob, I have learned from your replys in the past. I appreciate you posting thoughts/concerns. There might actually be someone here on occasion who can answer with the authority of first hand knowledge which is what makes this forum of any value at all, but usually that is not me. I was not at the meeting, so I don’t know whether they said that laminar flow was a problem…only that it was a requirement. In my opinion, the liquid flow would not need to be particularly fast, and it certainly does not have to be as viscous as water if the only purpose for going to a liquid is to control heat. Also, the amount of time the two laser beams will intersect in order to illuminate any single voxel will be miniscule. With a low flow requirement, and short (short is too long a word) periods of time required for a voxel to become excited by the lasers and decay back to its original state it just does not seem to me this is anything like ‘drawing in the river’. And remember this a prototype, will a commercial version differ? Probably.

Thanks for the great post and the review of history of TDCP.
I understand the problems that are associated with a laser shining on a fixed position Voxel, heat will build up and in a solid, that heat needs to be removed or the solid will start to be stressed. Distortion of the solid at the least and at the worst possibly fracturing of the solid. For instance, after twenty five minutes of operation, the cherry red glow of the solid might be a problem. Ha.

So the liquid method is the one best choice and possibly the only choice to move the heat to a cooling system. Continuous operation requires the removal of heat!.

I did talk to Dr. Hoover and he said that nano crystal are too expensive, which I would tend to believe. They know what to make the Voxels out of for a static image but they are having to make a number of engineering decisions related to continuous operation.

By the way, the liquid was not described. It could be as simple as water, or it could be something else.

Even using the current imaging material is having a duration of excitation problem which is creating a ghosting effect. This is a problem but only in a moving fluid. I remember some of the first LCD screens having a similar problem when they first marketed.

The thing to remember is if it had already been done it would have been a no brainer and no discovered problems.

I am glad that today's airplanes are very improved from the first airplane, but they do fly. Exposure to the elements and reliable operation are a few problems.

Thanks for this post. It sounds like you have brought up some very important concerns. I don't understand this technology the way some of you so thanks for picking it apart like this and looking at the details. I think you should direct this concern to the company and see what they have to say.......
