Re: [Electric Boats] curiosities

The insurmountable problem with tracking, concentration, and mirrors on a boat would be the fact a boat moves all the time. Even on land to use concentration you have to track the sun very accurately you have to be in alinement to the source 100% of the time, on a boat all these methods would be nearly impossible. The slight movement of a boat at rest would remove any advantaged of sun tracking not to mention under way.

The reason small scale concentration has not took off on land is after you add the lenses and tracking you have no real cost advantage over just buying more solar cells. Any company that has tried at small scale concentration has gone out of business pretty quick, on a boat these cost issue would be even greater. Try pricing three way tracking gear with enough persuasion to track satellite singles at sea this is the exact gear you would need to even attempt concentration at sea.

If you want solar on your boat just buy the highest efficiency modules they make, and cover as much of your surface as possible.

I am sure i have also seen that a mechanism to enable the pamnels to track the sun improved efficiency twofols

after watching a few video's searching "solar death ray", some people using parabolic dish, and some people using fresnel lenses, igniting all kinds of stuff pretty quickly...

there was another guy who'd built a solar boiler driving a steam engine, producing 12Kw of electricity, that array is pretty darn big, but why not a similar concept on smaller scale for a steam powered boat? clear weather dependancy is an issue of course, but the output could propel a hull, or charge batteries, or possibly do both on a good day. 12kw is like 16hp worth of energy, how big would it have to be for 1.5kw or 2hp? a couple larger tv sattelite dishes? boats DO rock around, could be a problem!

the idea could still make for a possible remote location charging station, feeding electric boats on a lake that isnt anywhere near a power grid. some solar panels on the boats to help, and a shack with solar steam..
an "eco friendly" boat rental biz? it might do pretty good till the fear based "insurance industry" and TAX MAN get involved (darn parasites!).

another charachter had a video "double your solar panel output", simplest thing I'd ever seen, he put up a mirror! has me thinking about low magnification fresnel lense panels over the solar panels for a similar effect, not the lens "sweet spot" where things burn, but if a panel can be tricked to do 50-70% more output, cost and required surface area go down.

I also like the ideas of Stanley Meyers "water powered car", was hydrogen extraction to run an ICE. unfortunately he was food poisoned when he signed a contract with the military, and the concept was silenced. he was using low current high voltage high frequency, to get maximum hydrogen extraction from minimal input. exhaust pollution? about zero! its a shame big energy will kill to protect their monopoly (racketeering!).
a boat that'd deliver 5-10hp or more, clean and FREE, would be wonderful.

sorry if the "politics" (many blood sucking parasites!) of energy is offensive to anyone (heck, it IS offensive theyre doing it!), and the fear based (now mandated?!) insurance industry that doesnt ever produce anything but is always in there demanding their cut too, it is what it is.
they've sure stifled anything innovation in the name of "safety", and to me its in direct conflict with the concept of "freedom".. when they're selling permission, imposing fines, fees, regulations, taxes etc.
("they" being them who never built-created anything themselves, EVER!,
-except of course their permissions, regulations, policies, taxes, etc.)

I know the "brainstorming rant" gets a few degrees off topic some ways,
related stuff lots of us really DONT like to think about. I sure can relate, to get out on the water is my idea of a good day too!

Hallo Popeye;

Thank you for sharing your thoughts. My thought is the only way to go
is electric with solar panels. And to have backup, such as original gasoline or
diesel engine. Sails for a sailboat. And batteries for the electric motor.
I also think it is good to have a generator on board to recharge batteries;
or to power the electric motor. Though this might be quite a lot and a bit of
weight and space. For me those are more important than a microwave oven,
or a refrigerator or a stove.
I am kind of a minimalist when it comes to comfort, and maximalist with safety.

These are my thouths. I do not have a boat right now.

Hallo,

Myforum name is associated with my boat name "Popeye's Tanjera" which
is a 46' Catamaran so i use Popeye!

I have been researshing electric propulsion for quite a while now and
came to one conclusion. There is no other way of generating elctricity
other than with fosil fuel. i.e Hybrid electrical propulsion.

I am no electrical engineer i am only a sailor that seek a afordable
and long terms peace of mind sailing with enough domestic power to
live a life i am used to and enough propulsion power to use when
needed. So i am bound to say things the wrong way, please forgive me.

I can olnly share what conclusions i came to and what principle i will be using.

Regards,

Popeye
