Re: Interesting Sailboats
"The beauty of what we've got is that, when it's fully developed, a company will be able to go out and buy what is a standard carbon-composite material, lay out the shape, put it through the curing process and have a structural battery," ...
In order to achieve this BAE said it had "merged battery chemistries into composite materials".
"You take the nickel base chemistries and there are ways you can integrate that into the carbon fibre," . …
"The goal, and we are still working towards it, is to have a material that isn't significantly more expensive than carbon fiber,"
However, the power density of the batteries, the energy they can store for a given weight, is currently quite low - about a third that of a car battery….
"You need a battery chemistry that will last for many decades, you basically can't just take a wing off and throw it away as you would a mobile phone [battery]," Mr Penney said.
BBC News - BAE provides details of 'structural battery' technology
This is just awesome and I guess that the reporter did not understood the potential of the new technology….quite low? The guy is crazy they talk about 1/3 of the energy that can be stored for the same weight on a car battery, that is huge. If a hull of a 36ft boat is entirely made with this kind of composite it means we will have a 3 to 4 ton battery. That means the capacity of a wet lead battery of 1ton on a boat
I want one of those, one boat that has a huge batery that can work for decades that weights nothing and that after fully charged will permit the use of an electric engine for days.
I guess that will solve the battery problem on electric engines for sailing boats.
Even compared with lithium batteries the hull of a 36ft boat will have the capacity of a huge battery, a 400kg lithium battery is a lot. And that is now; I bet they will manage to increase that efficiency at least for the double in the next years.
I guess that the solution for the autonomy for electric sailboats is found. What they really not found yet is that technology has an enormous potential on the boat industry
Now they only need to create sails that work as solar panels to have a perfect set-up for a really efficient sail boat. The technology for that is not far.
Thanks for posting
