The "Hotspur" an adventure magazine published by D C Thompson that I used to read as a boy had just such a spaceship touring the solar system but it seems they never got into production.

« on: 28/02/2019 16:07:35 »

I recently caught sight of a half white half grey squirrel in my garden it seems that the rare whites and common greys can hybridise (much like humans), it had a grey back and a white belly not the patches you see on Dutch rabbits and pigs.
I have left a camera handy but they are very timid and scamper of as soon as you raise a camera.

For about 5 years my garden was frequented by a white squirrel which I under stand only comprise 0.001% of the population ,alas he does not seem to be around anymore I guess a Cat or a Fox got him.
I have a healthy population of the common grey ones but apparently no hybrids

I have a explanation why people are so keen to dismiss GR and SR , while on an engineering course at Siemens Hell in Kiel I quoted Einstein to the "ex" Nazi instructor his reply "but he was a Jew"l

I do not see any need for runway light to be controlled by a hackable computer why not a few manually thrown switches. can we not have anything these days that is not computer controlled.

Does one really need to erase the last scrap of data on the phone to the degree that worlds best forensic labs will be unable to recover it.
If you have lots of kiddy porn or details of your fellow conspirators it is best to destroy it but if you are just passing it to the children just to download pop music why worry.
I found a G5 dumped in my garden and simply wiped it and use it I suppose I should worry in case it falls into the hands of the thought police and they find reason to prosecute me but you can't worry about everything

Just Chat! / Why does no one ever thank me any more

« on: 21/12/2018 20:42:33 »

Browsing thru some posts from 2007 I noticed that I had been thanked 44 times, 11 years later my total is still 44 I know my mental powers have declined as I get older but as I seemed to be well received until 2007 why did my comments and answer to questions suddenly become unworthy of any thanks comments.

Two bombs where dropped in rapid succession two convince the Russians that the USA had a plentiful supply of them, Stalin was not impressed he had better sources of information.

Physiology & Medicine / Re: Why Are Piggys Organs Like Human Organs ?

« on: 29/07/2018 17:12:45 »

The greatest danger to anyone with a failing heart that can only be treated with a transplant is that they will die before one becomes available.
Would it not be humane to allow people who have little or no chance of obtaining an human transplant that well may have dangerous viruses to have a pig one to see how real the problem is.
The chief concern seems to be that Porcine viruses could become endemic in the human sperm line but as yet there seems to be little evidence that this would happen from people who have received heart valves etc.
"A clinical trial study performed in 1999 sampled 160 patients who were treated with different living pig tissues and observed no evidence of a persistent PERV infection in 97% of the patients for whom a sufficient amount of DNA was available to PCR for amplification of PERV sequences. This study stated that retrospective studies are limited to find the true incidence of infection or associated clinical symptoms, however. It suggested using closely monitored prospective trials, which would provide a more complete and detailed evaluation of the possible cross-species PERV transmission and a comparison of the PERV "
This risk could be eliminated by sterilising recipients so that they cannot breed a small price to pay in return for the extra life a transport would bring.

Albert Einstein and a collaborator took out patents on a magnetic refrigerator.
I am in error here it was an adsorbtion type refrigerator with a magnetic commpressor

I think that whether or not it can be proved that they can perceive pain any animals that we eat should be killed first as if they can the problem arises with oysters that are normally eaten alive .

Back in the days when Wimshurst machines and electrostatics were all the rage I think they used to melt something like pitch and induce a charge into it that it retained when it solidified.

I think that any BH would have to have a mass of greater than the Plank mass to survive and that requires vastly greater energy LNC has.

I am old enough to remember pre war prices when we got 5 us dollars to the pound compared to the amount of hours worked to provide it some things like houses have become much more expensive while technical things like cars, phone calls , and communications. are cheaper (you could buy a house for the cost of an hours phone call to the USA or a large TV).
