Hello Folks,I grew some Iceberg lettuce in my gravel bed,and last night I cut
some for burgers,it was so bitter it was inedible!,anyone know why? Thanks Ken

Sounds like it was too hot (temp) during the last two weeks
of growth. How hot was the greenhouse at the hottest time
of the day?

>>>tvoivozhd---"free energy" is an oxymoron. Geoff Egel supra used to
run a fairly respectable list and even had the good sense to include
comments that most of the wild-eyed claims had no factual support, but
like most of the other pseudoscience sites has since succumbed to
converting gullibility to cash by selling books and tapes to playpen
engineers.
We are surrounded by energy too diffuse for use. The cost of collecting
and concentrating, converting and transmitting exotic energy exceeds its
value as relates to conventional hydropower, fossil, biomass, wind,
nuclear and solar energy (in a roughly ascending order of ultimate
cost)..
Whether or not energy is "free" is irrelevant. The only thing that is
important is its ultimate cost at the point of use as related to
competitive sources of energy. If, as in the case of the Japanese
Mighty Whale wavepower unit, it costs one billion yen for a machine
producing only enough electricity for thirty seven average Japanese
households, the present true meaning of "free wavepower" is "wildly,
exorbitantly expensive".
Another consideration which should be borne in mind is that all
utilization of energy has unpleasant environmental side-effects---this
includes those regarded as comparatively benign, such as solar, wind and
ocean energy. In small-scale use it is overlooked. In large-scale use
the environmental cost is more evident.
Multiple uses may occasionally make normally uneconomic systems
supportible---for example OTEC where refrigeration, production of fish,
fresh water, electricity are combined in an area like Israel or Hawaii.
In both, conventional fuels are non-existent and have to be imported,
and in Israel potable water is scarce and more valuable than most places
in the world. Few sites have the physical requirements of tropical heat
at the surface and great depths at which sufficiently cold water may be
found---and where equipment-destroying hurricanes and typhoons are
infrequent enough to risk capital investment and obtain affordable
insurance against weather loss. Dangling fragile pipes several thousand
feet in the ocean is a precarious business at best.as Georges Claude
found out with shorter pipes and a very low power output in 1932 off the
coast of Cuba.
There are no "hidden" or "suppressed" energy secrets, though some known
sources may benefit by improved efficiency in some aspects, such as the
recently patented acoustic energy transmission which will probably
replace compressors in refrigerators five to ten years hence. The only
thing the "Zero-Energy Devices" and "Over-Unity Devices" have in common
is that they either do not work at all or the output of a scientific toy
is trivial and non-scaleable.
At some future date it is not unreasonable that one or more new energy
sources may be found economically feasible. If so, they will be
patented, quickly exploited and a new Henry Ford or Bill Gates born.
Don't hold your breath, and don't look for any solution arising from the
pseudo-science sites who supply superficially plausible hope for people
who prefer virtual reality to an unkind real world based upon real
science and real fact.
Check some sites where real science is performed and archived. If ocean
energy is your thing, here's a few URL's for starters.

Marcy, I got your message on the aquaponics list. I am curious about what
you are doing and where you are doing it.
