Our blog articles

We produce, sale and license intelligent properties that are related to energy and ecology technology.


Kiwaho Lab’s operation object is that every our researcher or teamplayer should work out at least one innovation project per year, then file patent as salable IP (Intellectual Property).


Such a IP production rate will be our endless business year by year. We also form dynamic taskforce to undertake business partner's special research project in technical verification & improvement. 


Our hotspot of research changes time by time. As long as the innovation is ready for promotion, we will modify the homepage to reflect the newest status.


Recently we are focusing at technology of osmosis based energy storage & restoration.



Above is the embodied system of our novel method of indirect solar evaporation smuggled osmosis to hydraulic oil energy conversion.


With this breakthrough technology, a small portion of solar energy can be stored in the so-called salt panel or pond that emphasize its big surface area so as to maximize the evaporation rate.


Evaporation will concentrate the salt water to saturation, however crystallization is never expected, because its not for salt production, but for energy storage & restoration. Therefore, salt herein is just conservative working media.


As per experiments, the harvestable power density is 2.7 watt/m2 on the yearly 365x24 hours average in regular climate zone, and is expected of about 10 watt/m2 in arid or desert zone, because of quicker evaporation.


Therefore, to supply 1000 kilowatt-hours monthly energy, the area of salt panel should be about 520 m2 in regular district where annual precipitation is about 1000 mm.


The jargon “salt panel” reflects the intention that the salt solution is not supposed of too deep, if the ground is flat enough, even 3 cm depth is OK, otherwise 10 cm possible. The deeper the panel, the more backlog of salt is needed.


For personal or family energy independence, a shallow panel or pond can save lots of backlog salt; for commercial utility use, the depth is not important, even the deeper the better because of more storage volume.


If the solution concentration in the osmosis-to-hydraulic engine is regulated between 70% and 100% saturation, then the volumetric energy density is about 5 kilowatt-hours per 1 cubic meter.


Even during long time bad weather, it is not recommended of using electric resistor heater to evaporate salt pond, because circa 2.25% (evaporation effect on concentration) + 5% (temperature effect on osmotic pressure) = 7.25% (up to 13%, in extreme low humid or dry weather) electricity can be restored in osmosis engine. Try solar or ambient or waste heat or biomass combustion first.


During raining, cover all pond, or install permanent dog-height wall-less transparent simple roof.

Don't be screwed by PV. If it is good stuff, why the huge Morocco desert solar farm refuse to use PV, why China massively export? why Trump charges 30% tariff on import? For deep analysis & dynamic public reviews, click!
