Traveling much, I come across hundreds of different toilets and showers every year.
Why are they so crappy?
Showers are one of the few things essential to my life. Why are HOT and COLD reversed so often? (When the hot water tap works, the flow and temperature is often unreliable.)
Is this 1911 … or 2011?
Couldn’t somebody get rich inventing a voice controlled, temperature-accurate shower?
In 1959, Heinlein published Starship Troopers. Military life was rough … but at least they had individually programmed shower routines.
I have seen a few good showers. The best of the best (surprisingly) were in campgrounds.
Due to remote location, campgrounds often must hack their plumbing, inventing unique solutions. Once in a while, that solution turns out better than the cheapest, minimum-code-allowable versions we get in cities.
This toilet in a Swiss campground worked perfectly.
A commercial product, it’s as steep and deep as any I’ve ever seen. No splashback. No need to brush.
It had an old style individual water tank mounted high.
Gravity does all the work, a simple mechanism. The force of water falling from just a few feet was tremendously effective in flushing.
I’m no plumber. (My IQ is higher than the maximum allowed.) But I’ve been studying plumbing since visiting Gandhi’s toilet research centre in the 1990s.
Why is toilet technology evolving so slowly?

Re: “Device for Automatically Dispensing Chemicals in to a Toilet Water Tank”
(Patent Application, Israel)
Dear Sirs,
I have developed a new device for automatically dispensing the detergent into the toilet water tank.
This device is very portable and mounted in the free hole of the body of toilet tank. The weight of this device will be not exceeding 300 grams.
It should be noted. The proposed device can be successfully applied for a long time
for tanks with external mounting and for hidden toilet tanks.
Capacity with the chemicals is attached to the device. Cleaning detergent with small amounts is dispensed automatically in to the water tank. One portion of detergent equals one water discharge. Capacity with the cleaning agent can be replaced once per year.
Exploitation of this device is quick and easy and it no need for special tools
I believe that the company owns such an automatic device and a new cleaning liquid can get a significant market segment in North America and Europe
This should take into notice that this device, other than residential premises, can be effectively used in areas with large concentrations of people: restaurants, cafes, schools, bus stations, airports, industrial plants, etc.
Sale of cleaning fluid and a device for its dispensing can be done by major trade
networks (such as “Home Center”, “ACE”, etc.) that sell detergents, flushing cisterns and parts for them.
Therefore, I appeal to you an invitation to participate in the expansion of patenting the specified device, and to consider my offer to purchase a license to its production and sell.
Regards,
Yafim Gisser
