Eating fake meat made from mealworms that were fed fermented soybean husks.Seems technology is coming on so fast. We have the solar panels, swapped out the Tungsten bulbs for LEDs, got air source heating, went over to induction hobs, have plans to go over to thermostatic radiator valves, replaced the petrol car with a small turbo-diesel (an extra 30 mpg is hard to ignore)... I know some think it's daft tree-hugging BS, but it makes a difference to the bills, which means more money for important things, like guitars
So, what is up and coming? What is the new Big Thing in efficiency? By which I mean, now affordable, accessible, and as good to use as what it replaces.
Certainly makes sense and we've also heard of spinning big flywheels up then harnessing the decay but I wonder how much of the energy used to pump water uphill is actually saved vs lost? Has to be significant losses in running electric pumps then running turbine generators?I just read a really interesting article on pumping water as a form of energy storage to manage grid demand:
Batteries get hyped, but pumped hydro provides the vast majority of long-term energy storage essential for renewable power – here’s how it worksA team of researchers found 35,000 pairs of existing reservoirs, lakes and old mines in the US that could be turned into long-term energy storage – and they don’t need dams on rivers.theconversation.com
Basically authors located sites were there are lakes or reservoirs in a elevation relationship such that you can pump water up during peak times and then generate power as it flows down in off peak.
The article includes a link to an "atlas" of thousands of potential sites worldwide. It's very interesting--clearly not problem free, but also potentially viable.
