I only commented because I had reason recently to remove a strong padlock from a gate, where I had lost the key and I was shocked by how quickly I cut through the hardened steel. If it was 2 seconds or less . More time spent reeling the cable for the grinder

I can agree with all three ideas, the movement from lead acid to li ion was exponential, the current gains are incremental and even plateaus have slopes.. The fundamental problem about future major advances is that with lithium, one is dealing with one of the lightest elements so unless one...

A very nice job, unfortunately I would give it at best 5 seconds security against a cordless angle grinder. Fitted with a diamond edged disc.

There is a long history of this.. of governments funding criminal or dissent groups to sow mayhem in a opposition camp. , And then after that conflict is over the group continues to do what it does best. The USA took a moribund criminal gang in Sicily in the 1940s for the war effort which...

Well if they are well secured then they are hardly loose!. My point is was that the finishes inside caravans are nice and pretty but not robust or strong. If a bike with its sharp metallic bits be they pedals, brakehandles , wheel nuts or whatever get a chance to slide against doors and panels...

Your original posting was a query on why the 4 amp Bosch chargers were significantly heavier and larger than the 2amp ones. A 20amp 40 volt output is 800 watts. Many of power supplies used in personal computers are at that or higher levels and are not as heavy as the Bosch 4 amp unit. Consider...

Of course we know about the potato famine, there were other forces at play there. The Irish population grew very substantially in the preceding two generations, primarily as a result of prosperity resulting from the neapolonic wars where Irish corn, horses and timber were a major part of the...

Steve, There is a lot to admire in the best of British... I shouldn't need to be the one to remind you of that Other nationalities all have their own quirks and foibles also. Slavery was not invented by the British, in fact they were instrumental in making it unacceptable. Colonism was not...

The video is frightening and their activity is highly dangerous particularly to themselves. The only consolation is that automobile traffic in Manhattan is very sluggish. And they do a slow down at pedestrian crossing. Note the discipline of the pedestrians ... no jaywalking.

That's a fair point and is exactly the reason why justice is supposed to be blind. Otherwise it is just vengeance. Actually in this matter I probably would not have been spitting etc I can speak from some personal experience in that a car misdriven by a young man mounted a pavement and broke...

Well said!

But time is of the essence and which side has wasted it. I agree that if one wants a negotiated result there needs to be give and take and respect for the other sides viewpoint and patience is an excellent virtue. But and it's a big but there is no evidence that a the UK side has a coherent...

Bikes loose inside a caravan will destroy the interior all it takes is a few silent policemen .. those ramps in the road. Years ago I made up a frame using timber to hold those bicycle brackets used on car roof racks . It worked ok but there is not much space in or around a caravan and the...

I must agree that he had no brake singular as required by law .. It manifestly was not attached to the front wheel which is the requirement in law. However pedals directly attached to the front wheel are allowed as meeting the legal requirement as per fleccs original quoting of the act, so leg...

I agree that the points you make about ebikes are valid. What might be added is that they increase average speed while reducing peak speeds.

The cross sectional area of copper between 2A and 4A needs is neiglible. Why the 4A charger is larger could very well be due to the vintage of the Bosch factory being used. Its intended to be used at home so making it lighter is not a priority. The thickness of the cables and the...

whether you choose to respond is your prerogative. But there are still a number of points in your posting which deserve refuting. 1. As you rightly say my assertion that he had remorse is an assumption just as is yours that he hadn't. Neither of us can see inside his soul. It would not...

Hi zalthan I note you have disagreed with this posting in which I had made a number of assertions. Which ones did you disagree with as opposed to dislike?

The charger would not need to be much bigger. Consider that the power supplies for pcs can range up to a 1kw and are lightweight . However I don't think that the battery charging scales as simply as that. There is an optimum charge rate and if one increases the applied voltage... the only...

If burning calories is your aim, the best way would be to run up the stairs, in the nude of unheated tower blocks, preferably after taking a cold shower and in mid winter. Allow yourself to eat pickles soaked in vinegar and plenty of water. All other activities cannot compare. The result will...
