Know thyself … or wound others

Even in the tiny, quiet town of Smogdale, UpNorth County, in the UQ (the Untidy Queendom of Little England), the traffic congestion is getting so bad that Kevin the builder ha s a problem. Despite being a couple of inches short of 7 feet tall, well built and notoriously energetic, he doesn’t want to carry … Continue reading Know thyself … or wound others The post Know thyself … or wound others appeared first on pjf.

Solar energy to produce hydrocarbons from climate change pollutants

Recent breakthroughs in semiconductor physics have produced the possibility of using solar energy (photovoltaic generation) to capture CO2 (carbon dioxide) from the atmosphere, but, most importantly, to do so where it is being produced by industrial use of carbon based fuels which currently contribute to climate change pollution. Using DC electricity to electrolyse water into … Continue reading Solar energy to produce hydrocarbons from climate change pollutants The post Solar energy to produce hydrocarbons from climate change pollutants appeared first on pjf.

energy policy for a sane species

Imagine that the human race was capable of consideration for others, rationality and honesty. What would the world’s energy supply look like? The most recent estimate of global energy consumption is for 2013 – 5.67 10^20 joules A kilowatt hour is 1000 x 60 x 60 joules = 3,600,000 joules = 3.6 10^6 joules. So … Continue reading energy policy for a sane species The post energy policy for a sane species appeared first on pjf.

1.2 gigawatt offshore wind farm

Currently the world’s largest offshore wind farm has been given the go ahead in the North Sea, 75 miles east of Hull, England. The 1.2 gigawatt (1,200,000 kilowatts) is expected to generate enough power for one million homes. Wind power is crucial for the UK, as we experience more wind in the winter when solar … Continue reading 1.2 gigawatt offshore wind farm The post 1.2 gigawatt offshore wind farm appeared first on pjf.

Solar power inverters – efficiency and self-reliance

Tata, the car manufacturer (and more) and one of the first to make a budget electric car, now has an offshoot called Tata Power Solar. It is releasing a solar PV unit that stores electricity from PhotoVoltaic panels in batteries to power an inverter (to mains AC) to replace the domestic mains when there is … Continue reading Solar power inverters – efficiency and self-reliance The post Solar power inverters – efficiency and self-reliance appeared first on pjf.

new solar thermal material

A new solid state material has been developed that stores daylight in a solid state form (like batteries) without the need for expensive batteries.  It can be triggered to release the energy as heat on demand, so simple applications such as harvesting energy during the day to heat the building after dusk are proposed Research … Continue reading new solar thermal material The post new solar thermal material appeared first on pjf.
