Archetypal Cambridge

The photo is archetypal Cambridge with bikes and posters. It shows the university church Great St Mary’s, which is about 200m from King’s College Chapel. The Senate House, where many degrees are given out, is behind.

Special Lunch

On Monday our son had a special birthday so we treated him to a nice lunch in Cambridge.

RGO-One QRP HF transceiver

This was found on the internet the other day. 

It looks a very handsome rig, although I do not think it was ever mass produced. 

I have never seen it for sale.

The windmill next door

This is the windmill right next door with the sails turning this morning. This was taken from the lounge window. They only have the sails turning occasionally. 

Electric cars - are we still waiting for a breakthrough?

It seems to me that we are still waiting for that breakthrough moment similar to that which moved us all from CRTs to LED displays or moved cameras to digital. 

In the case of cars it would be range and cost. Almost exclusively electric cars need batteries with lithium and have limited range. Imagine if we could charge at home infrequently and have huge ranges at a price people could afford.

There has been a lot of excitement about Donut batteries who claim to have produced a solid-state battery with some remarkable figures. If true, this could be the start of a revolution. I believe the Chinese company BYD has also released an electric car that does not use lithium batteries.

If we really could buy cars that no longer need petrol or diesel with similar ranges we would be free of the stranglehold of the oil market. 

It is coming, but just how soon?

Kings College Chapel, Cambridge, UK

 

This was King's College Chapel in the afternoon sunshine yesterday.

It was nice to see visitors enjoying themselves.

King's Parade is a popular part of the city.
