Soil carbon storage

On 13th Feb we gave a presentation on soil carbon storage to Reading U3A’s Members Meeting. The presentation was titled “Burying Global Warming: Carbon Gardeners Question Time”.

In conjunction with growing more plants, soil carbon storage is at present the major means available to us for extracting carbon dioxide from the air, and thus tackling the climate crisis.

The natural processes of Earth’s “carbon cycle” move carbon into and out of the soil. We can help nature to increase the amount that goes in, and to increase the time it spends there. Both of these keep carbon out of the air.

The presentation gives a high-level overview of numerous options for achieving these effects.

Heat batteries

On 28th Jan we gave a presentation on heat batteries to Reading U3A’s Science and Technology group.

Heat battery technology has the potential to transform the way we heat our buildings and our hot water supply. Batteries decouple the time at which heat is needed from the time at which it is generated. They are more compact and efficient than hot water tanks.

Heat batteries can store energy from any kind of source, such as a heat pump, a biomass boiler, solar panels or cheap-rate grid electricity, and save it until we want hot water in the mornings and warm rooms at night.
