Would you buy blocks of ICE ?

I will have a lot of excess energy from my 4kw of solar panels.
I have been wondering what I can do with it.
One thought is to run the watermaker and sell fresh water or freeze it into blocks of ICE. Is this something other cruisers would want or need?

Your A/C can easily eat up your excess Watts. In the tropics, ice blocks are always nice to have! See if you can barter them for canned goods or fresh produce. Mauritz

Re: Would you buy blocks of ICE ?

I know in the Sea of Cortez about 20 years ago you would have been "the man", as many cruisers back then seemed to be on a constant search for ice and water. I'm thinking today the demand wouldn't be as high.

That's a lot of solar on a 38' Cat. I'd like to see pics of your set up.

The boat is under construction, won't be 38ft cat anymore, current plan is 50ft.

The 4kw of solar covers 700sq ft, so yes it will be interesteing to see it..
I built a 1/12th scale model of the 38ft design, I'm redoing it for 50ft.

I plan to spend a lot of time in the sea of cortez, so a lot of sun and wind there.
Today they have desalization plants, so plenty of fresh water available, but I'm thinking getting block ice of fresh water without going ashore might be useful
to other cruisers. That would a lot easier to do than other ideas of using 2000 amps of power every day.

Re: Would you buy blocks of ICE ?

nimblemotors,

If you get too carried away with solar panels, your boat might look like this....


Or this.....


Or even this.....


But hey, with the cost of solar I'm with you, as much as the boat will support.

Re: Would you buy blocks of ICE ?

IME, making money off of other cruisers is not so easy for they tend to be a frugal lot. My guess is that despite the desirability of big chunks of ice in remote anchorages, the sales would take a long time to reimburse you for the freezer box necessary to produce big blocks (anything less than 5 kilos or so is a waste of time).

And while 2 kw of solar sounds like a lot of power, it takes a lot of btu's to freeze 5 kilos of water. You might want to look carefully at the math for that operation before you spend the money for the freezer!

Cheers,

Jim

It is 4kw of solar, and that is just solar, will have wind power also.
The frugal-ness of cruisers is what makes it viable -- will be cheaper from my boat than going ashore and/or making ice yourself.
I don't see a freezer as having much cost, I will make ice for myself anyway,
and use it as cold for a/c even if not efficient.
(edit, looked up 6kw-hour to make 100lbs of ice, so the boat can make at least 200lbs of ice every day, at 10lbs each, need 20 customers every day, hmm )

What else might one suggest I do with gobs of power EVERYDAY that isn't used? If the sun is shining or the wind is blowing, my boat is making 300amps every hour..

Yes, sorry about the mistake about your power capacity. 4 kw is a lot... when the sun is shining.

I'm not sure what sort of freezer you are contemplating. The average yottie job isn't designed to produce big blocks of ice, so what do you have in mind?

I agree that you might be able to provide ice for less money than going ashore for it... maybe. We left the Sea quite a while ago, but back then there was very cheap ice available wherever there was a fishing fleet... that may well have changed. But, besides being frugal, not that many yotties use block ice any more, so I'm not sure who your customers will be.

Anyway, if it lights your candle, give it a go. But I'm going to wait to buy stock in the Nimble Ice company!

Hmmm... maybe you should be using that power to dis-associate water into oxygen and hydrogen and using the H to run your engines!

Good luck with it

Jim

Re: Would you buy blocks of ICE ?

Like I said, 20 years ago a much needed service, today not so much. Maybe a dive compressor to burn up those extra watts.

huh, fill dive tanks? might be good idea at places with coral reefs to dive, not sure mexico fits that profile.

I snorkeled S of C, but there are areas divers enjoy. A lot of varied sea life down there. I used to dive Monterey Bay, not near the quantity or variety as Baja.

Re: Would you buy blocks of ICE ?

Hello Nimble, I love your idea's conserning solar energy. I have been dabling with it myself. Also the idea of trading commodities at sea is a very real good idea but not so well sought after as we sailor enjoy being self sufficient and plan for such things. However with the right kind of marketing Iam sure you can turn it into a tradable commodity. if you allow currancy to be exchanged then you are opening yourself up for trouble with taxing athorities. Trust me these grubby little bastered want to steal from your trade so be carful using currancy for trades lest you buy the priviledge of doing do. For me Commonlaw is the only real way to keep them from claiming jurisdiction. Also, Ice is one idea but you can also use solar energy to make hydrogen to burn as a gas and this can be used in any motor even to cook four food with but be very careful. Hydrogen is explosive but there are was to ensure safe usage. So back to common law trades. You can do so many things to barter your way across the sea or just lessen the impact of accruing costs. Never a get rich quick scheme but a crutch nonetheless. I have found if you place a small sign on your boat "Common law trading post" "Barters only". "ICE" available (or all commodities traded) then when you come into port place the sign for all to see and when you go ashore place an i'll be back at "oclock" sign or simply remover the trading sign. Good luck and I am sure you will find ways to get ride of that ice quicker then you might imagine. You can also find where the sailing groups are gathering and ensure you will be there as well. Happy daze!
