"Carbon dioxide emissions from plug-in hybrid cars are as much as two-and-a-half times higher than official tests suggest, according to new research"

The main attraction would appear the benefit in kind taxation charge !   Many ex company full hybrids appear at car auctions wit the charging cable still sealed in it's original packaging  !

ok now im home from work. When I deal with EV and hybrid cars at work its with a sense of trepidation and special tools. Now your not just connecting to a row of batteries to an electric mot

I think that was kind of the point I and others made above?

Actually, while battery density is indeed quoted in wh per litre, the experimental Samsung batteries are claimed to be close to the same figure per kilo.

If you look at the development of vehicle batteries over the last ten years, energy density has dramatically improved. Look at the first-gen leaf and the current one, then compare the battery capacity and the vehicle's overall weight.

But yes, as mentioned earlier it is likely that fuel cell is the answer.

What I was talking about is the potential of having a decent (say 100KWH) battery pack on a boat in order to provide domestic and propulsion power for a time (say proper overnight electrics, and power below 4mph) but with a fuel cell there to keep thing topped up during daytime hours and when the boat is moving faster.

Think of the noise benefit. People say diesel isn't a problem but I bet if you had a near-silent cruiser you'd love it. We all would.

Well, some really good and informative and well thought out posts coming on here today. Learning loads. Such a shame the Like button is not working.

 

Am going to make a bit of a tongue in cheek remark here - please don't all rush out and buy new EVs will you. I need enough power kept in the grid to keep mine charged !

Having watched a programme on the production of copper for wires, it is massively destructive to the earth and consumes huge quantities of power.

How much copper wire will be needed in EV, batteries and supply cables. Not very green compared to diesel and petrol units.

So...a boat to tour the Norfolk Broads with as small a carbon footprint as possible, composed from biodegradable or recyclable materials that could offset part of the carbon bill of it's construction...er...why are we trying to reinvent the wheel?

They are, yes. Emissions tests are well-known to be total balls.

But the article also pointed out that they're still at least a third cleaner than regular vehicles. I'll take that and having driven a proper hybrid recently I would have to say they're pretty good.

Back to the subject of boats and lecky. Then putting posts in yards where there used to be diesel outlets makes perfect sense. But what of the outcry from the larger craft, both hire and private, if they are not provided with posts  to enable them to enjoy bankside moorings and still have their hotel room and kitchen type luxuries ?Are their expectations too high?

Looking around I would think the number of BA moorings with suitable access for charging points is pretty much maxed out now, as for Marinas the supply in most of them  is not that reliable tripping out with minimal loading now.
