As an island surrounded by water why is there not more tidal power. The tides are guaranteed, wind isn't.Does it offend anyone else that England imports so much of it's power, we live on a windy island

That is already underway with multiple projects around the UK however England seem to be lacking.As an island surrounded by water why is there not more tidal power. The tides are guaranteed, wind isn't.
Interesting real life ev woes
Tidal power has it's own issues, personally I think it's suffering from under funding and deliberate miss costing but taking a large amount of energy out of the sea has consequences, get the hydrodynamics wrong and you can end up with a constant need to dredge to keep the system running. In some areas you need to sort out the poor levels of sewage treatment - not reasons to give up on a very reliable power source. At small scale wave energy used as protection to eroding coasts has potential to fix two issues at the same time. I'm certain it will be an increasing part of the mix, we do seem to love putting all our eggs in the first basket to come along.As an island surrounded by water why is there not more tidal power.

I am surprised more use is not made of hydro power in this country. My father worked with the North of Scotland Hydro Electric Board, and recalled the enduring success of dams built in Scotland to generate power just after WW2.
He also had a set of 1890's bound volumes of Work, An Illustrated Weekly for Mechanics, which featured everything from woodwork to early electric systems. Included were details of small-scale hydro turbines quite widely used by Victorian landowners.

Agreed at present most useful as a second car, I still think the way forward is a hire contract, for me most of the time I would want the smallest cheapest, lightest vehicle going just to get me 20 miles each way to work or as tonight take my daughter to Scouts and back and do the odd small shop. It would need to be quick enough not to be a liability on a duel carriageway say 60 mph. I want batteries I can lift out, two trips is fine if it gets me 100 mile range so I only do it twice a week and have the option to charge a spare set indoors slowly on cheap rate power if I'm not using a charge point. BUT sometimes I want a 4/5 seat car like the one I drive now with a range over 200 miles even with the lights on and the heater running, very occasionally I want a van or a pick-up. I think there are a lot of people in my position, if we all drove micro cars there would be a market for people to hire the other vehicles to us as needed either as direct swaps on the same contract or as at present the way I sometimes hire a van. Volume is the key, the car I started this thread with is a disappointing $16,000 built in high volume I could see that being halved. Sort out the power generation and storage issues, put solar panels on warehouses before green fields etc and we are there - simples! .....or not.The minimal car really starts to work either as a second vehicle in the household, or when they can be delivered for use on demand.
A minimal car needs to be defined - say: max speed of 50-60mph, max weight of 300kg, space for 2+ a few shopping bags, range ~30-50 miles. Small low weight means small batteries which means 13amp charging generally feasible.
To encourage adoption - priority or free car parking, no tax, possibly driven by 16+ (as mopeds etc), no VAT on purchase, use bus lanes etc.
As a second vehicle this could be attractive to a lot of city and town dwellers - covers most shopping, school run, short or moderate commutes, local socialactivitty etc.
Milton Keynes are also trialling an app based system where a remotely driven small car is delivered, you drive to destination, remote control drives it to next user (or recharge station). This may turn out to be the future for many.
The point is that in the UK, we've run out of suitable geography for hydro. Much of our existing hydro is used for energy storage - 'pumped hydro'.It blocks rivers, changes downstream environment through slower movement of debris etc., blocks fish, blocks canoeists. I think I saw a few days ago an old dam being removed from some Scandinavian country, and there are companies which will remove them for you - Home - Dam Removal Europe
