EEStor Revolution



We have posted on the EEStor ultracapacitor development and its apparent iminent debut. Others are also advancing similar protocols and all are optimistic that they can deliver an energy storage device that can store and control sufficient energy to provide personal transportation comparable to present ranges or at least ten to fifteen times better than present electrical storage devices.



Surprisingly the challenge is technically clear. You need capacitor spheres to hold electrical energy and you need a control system. Because you can initially start with large dimensions, the control system can be solved independently and we can presume this was done long ago. So far, so good.



If you can do all that then energy content becomes a case of decreasing the size of the spheres in order to increase the size of the surface area. In fact it must get down to nanometer size to achieve the desired results and apparently this has been accomplished. Thus their claims of iminent deliverability appear creditable baring the usual last minute technical difficulties.



So we are about to have a magnificent super battery as a stock item of mass production. Others will be also producing a comparable product.



Now this has all been focused on the automobile industry. It is way more important than that.



It will completely change the whole business of energy. To start with, it becomes practical and desirable to establish a consumer owned energy production system. This way the consumer avoids the cost of distribution. A simple initial model is an energy efficient house that collects solar energy on a continuous basis. The house collects energy during the day and supplies what is needed during the evening and night. Then as the sun rises, it automatically tops up the automobile draining the storage device in preparation for fresh accumulation.



Surplus power can even be collected by mobile units, completely avoiding the need for grid linkage. We are assuming an efficient energy transfer system but that seems likely also.



The point that I am trying to make here is that this turns everything we have done for the past century on its head. It is already possible to take a home of the grid with some expense. It now becomes convenient and economic.



This also releases a massive amount of energy back to the primary producers for industrial use and that includes much of that energy lost to transmission losses.



So not only are we having a practical electrical automobile protocol, we are getting a practical home energy storage system that naturally promotes the investment in home based energy production that efficiently integrates into the overall energy supply system.

Atmospheric Water Collectors

Our instrument for terraforming a third of the earth's surface must be the stand alone atmospheric water collector. It is appropriate to discuss the outstanding technical issues that will need to be progressively resolved.

The design concept is simple and minimal. A solar panel will collect sunlight and convert this to electrical current. This current is then stored in a storage battery. At night, after the temperature has dropped, this stored energy is used to operate a reverse refrigeration cycle drawing moisture from the atmosphere. The produced water is fed directly into the root ball of the tree.

We have four components: 1) the solar panel, 2) the battery, 3) the reverse refrigeration water collector, 4) The controls. As is obvious, items 1, 2, and 4 are readily available in some form today and can already be optimized for this particular application.

We even know that the most costly component, the solar cell is likely to drop in cost by an order of magnitude which is critical to the global adoption of this technology. And the battery technology may be easily optimized by simply taking advantage of the fact that this battery does not have to be lightweight.

That leaves us with the task of producing a simple device that captures prevailing air flow, perhaps inducing some acceleration to drop the temperature a little more, and flowing it over a cold surface to draw the moisture out of the atmosphere.

Here there is ample room for design imagination and I throw it open. We do not want too many moving parts, but I suspect a fan will be valuable to control air flow rate. The only design parameter at this point is the need to produce 100 liters of water inside of six hours.
