Come on don't run yourself down!

Yes.. the Openhydro operation manufacturing in Greenore is a world leader. The strangford Lough kit was if memory serves, an 1/8 scale version of what they plan as the production model

.. don't see the arguement about three hours. As I see it, the li ion is the buffer and the PEM is the charger. The PEM is slow reacting, needs to get up to operating temperature.

Its fuse won't blow as it takes a while for the fuse wire to heat up to melting point. And by that time the trafo has stabilized. The CB can trip because the large current has mechanically accelerated the armature in the circuit breaker with the initial impulse. there are other CBs which have...

A colleague of mine once suggested that a bar code tattooed on one's bottom, was an ideal identify system. Bar code scanners in every public convience, would provide location data on typically a daily basis . Short of flaying, it would be impossible to steal, and only the constipated would be...

As a person who rarely takes taxis, or hackney and is hazy about the distinction between them, my observations would be along the lines of.. . There is about the same amount of energy consumed in making a car and dismantling it at end of life as there is in filling it with fuel during its...

The maintenance costs are higher than at first sight... sand moving in turbine wheels is pretty abrasive and sea life growth barnacles etc a constant annoyance. There is a very nice one on the rance in northern Brittany. But once the civil engineering is done the bulk of the capital...

Not being a conspiracy theorist but the event you are referring to was where a Chinook carrying a number of NI security specialists died. After that there was movement and the agreements followed. I reckon that the vacancies created allowed new thinking or that without the expertise which...

Flecc, not as unusual as one might wish.. we in Ireland had an event last April, where one of our air sea rescue helicopters, crashed into the sea off the western seaboard. It is particular interest in my village as one of the pilots lived with his family here. The circumstances were that this...

As far as I know, energy from the sea is limited to 1. Collection of surface wave energy 2. Currents underwater similar to wind turbines but stubbier 3. Tidal barrages 4. Thermo Cline , heat machines 5. Osmotic pressure at riverine saltwater interfaces. 6. Harvesting thorium and other...

Whenever the discussion on sustainable energy decends as this one is in danger of doing , I always recommend that the protagonists, would back off a little and instead take the time to read David McKay, freely available book, .. both available in hard copy form and as a free PDF called...

Not silly at all,... Granted wave energy is a derived form of energy coming from wind, but Wave power is a more concentrated form of energy, where mother nature has done the concentrating for us, and even better, is a time delayed resource, so helps reduce fluctuations in energy. Since we...

If it's tripping a circuit breaker, then it is inrush current, and you need to replace the CB with a slo blog type. Alternatively you need to put some thing in the line.. traditionally a thermistor would be used. But .a car bulb would act very effectively as well. After the power on switch...

No way do they require that level of current..on the input The 80 amp would be available at the output terminals at say 3 to 4 volts.and into the welding rods. It might assist if the op posted a picture of the faceplate .giving it's power requirements.

I respectfully disagree , certainly with the first part. I believe that Martin McGuinness did his best to keep the show on the road, and it was the intransigence of Ms Foster which forced him to withdraw support. What was normal parliamentary procedure, whereby someone would recuse themselves in...

Confidence is not how I might gave described it. It simply a belief that the current UK government see NI solely as a source of a few critical votes. Beyond that they see nothing . It may eventually dawn on them that there must be borders outside . There were interesting interviews in...

That is a genuine pity. The people of NI deserve a parliament. But there is enough hypocrisy up there to cover all the parties. The suspension of stormont was a spectacular own goal by the dup. The marching in tune with the UK conservative party in defiance of a strong pro remain...

I don't know... You've rarely let propriety stop you in the past;-)

That is consistent with what I had heard about the training of surgeons with this kit... specifically peeling layers of the skin from a grape. However we are really moving off topic ..which was the probable reduction to the workforce post Brexit as a consequence of the two pressures of less...

We might be better leaving it there. Solar semantically means deriving from that specific blob of hydrogen and other stuff some 93 million miles away. Stellar means from any star... Supernova.. an end stage for some stars and that brilliant piece of observational science of the collision of two...
