Chapter 16: Questions and Answers
This is a fast-moving field of research and development, and one where a single person working alone, can
outperform research establishments with unlimited budgets and many staff members. If you believe that the
answers given below are inadequate or incorrect, then please tell me as thisis definitely a learning process for all
of us.

Topic: What To Build
I am regularly asked to recommend a device for someone to build. This is an impossible task as the person
asking never says in which part of the world he lives, how much money could be used in the project, what tools
are to hand, what workshop space (if any) is available, what local supplies of materials is like, whetherthe home is
in a city or an isolated remote place, local assets like a shoreline, a fast-flowing stream or lots of sunshine all year
round, how much ground space is available, what his skills are, etc. etc.
What should be realized is that a small group of friends can achieve a great deal. If one person likes working with
engines and another can fix television sets and a third can weld, or …whatever. By working together, they can
achieve a great deal and benefit both themselves and their friends, not to mention having a good deal of fun in the
process and ending up with a great sense of achievement.
We should not dismiss the various forms of renewable energy such as wave power, RAM pump, solar panels,
wind power, biomass and the like. Granted, they do not always provide power all ofthe time, but if they provide
most of the power you need for most of the time you need it, then that can be a considerable saving on your
present power costs, so you should consider the devices covered in chapter 14. One possibility is to use a RAM
pump with a fast-flowing stream, to pump water up into a water tower over night, and use the tank of water to
power a turbine driving an electricalgenerator when needed.

If you have the space and the sunshine, then a parabolic mirror can focus the sunshine, produce steam and drive
a generator, a mechanical drive, a pump, or whatever else is needed.

If you are lucky enough to have access to a small section of coastline, then using either wave power or tidal power
gives a major amount of power each year with even a simplelow-tech construction like this:

It is not necessary to "go for broke" and aim at a device which will completely do away with your power needs for
evermore. Initially, it can be a major step forward to produce a device which reduces your energy bill by a good
deal and later on, progress to an additional system which makes you fully independent of others. For example, it
is perfectly possible todrive a RotoVerter (chapter 2) with a solar panel:

The output is much more powerful than the input from the solar panel and can be used to run power tools, charge
batteries or perform other useful tasks at effectively no cost at all.

The Frenette heater (chapter 14) does give significant heat output for the modest power input needed to spin the
central shaft. It is a simple constructionwell within the capabilities of most people, and it could be driven by a
solar panel if you live in an area where it is cold and sunny. As the array of discs spin, the vegetable oil inside the
cylinder gets heated and pushed upwards and outwards, flowing through the radiator tubing, heating the house:

There are many high-performance alternatives which need special skills or equipment tobuild, but these can be
found and constructed by those people who have above average skills and workshop facilities.
Devices which can provide power at any time, and at any location, include running a standard electrical generator
with water as the only fuel (chapter 10). Strictly speaking, the generator runs on energy drawn from the
environment and not on water which itself is not a fuel, but as...
