This Heat Pump Uses Sound

Normal heat pumps make use of chemicals to modulate temperatures, in the future they may all use sound. A new French startup has announced they will sell a residential heat pump using acoustics. It’s not loud since the sound waves stay in the system to change the temperature, which also means the system can be quickly adjusted. Using acoustics for temperature control isn’t new (it’s used on the James Webb space telescope), this application of it in a residential system is novel.

Loyer said the heat pump can generate domestic water at up to 80 C. He claims that one of the key benefits of the acoustic heat pump, in comparison with traditional units using refrigerants, is its ability to reach very high or low temperatures.

“Traditional heat pumps use refrigerants with a temperature phase. They a have temperature limit, which is the temperature of the changing phase from liquid to gas of the refrigerant,” said Loyer. “In our core, the helium stays in gas form. Because helium remains a gas until -200 C, we can achieve higher temperatures inside our heat pump core.”

Futuristic Fusion Finally Fires Up

Fusion power has been just a decade away for decades, or at least that was the joke. Yesterday it became outdated because it was revealed that nuclear fusion was ignited, stabilized, and proven to work reliably. Fusion energy is carbon-free energy production which has the potential to revolutionize how we use electricity. Hopefully we will be able to replace major power plants with this carbon free fusion solution.

To be clear, there’s still a lot to do to get fusion energy connected to the grid. We still need to focus first and foremost on renewable energy sources.

“The pursuit of fusion ignition in the laboratory is one of the most significant scientific challenges ever tackled by humanity, and achieving it is a triumph of science, engineering, and most of all, people,” LLNL Director Dr. Kim Budil said. “Crossing this threshold is the vision that has driven 60 years of dedicated pursuit—a continual process of learning, building, expanding knowledge and capability, and then finding ways to overcome the new challenges that emerged. These are the problems that the U.S. national laboratories were created to solve.”

France: Parking Lots Must Have Solar Panels

Drivers know all too well that parking lots are hot, uncomfortable, and are never the right size. In France larger parking lots will now require shading in the form of solar panels, making the large swaths of asphalt a little more comfortable. The solar panels are projected to provide the equivalent of 10 nuclear power plants.

Imagine if a law like this was passed in North America – we wouldn’t need any other source of energy!

Starting July 1, 2023, smaller carparks that have between 80 and 400 spaces will have five years to be in compliance with the new measures. Carparks with more than 400 spaces have a shorter timeline: They will need to comply with the new measures within three years of this date, and at least half of the surface area of the parking lot will need to be covered in solar panels.

Farm Fields of Solar Produce Bonuses

In the UK the average person wants to get off fossil fuels, but the Conservatives in power want the opposite. Obviously this is not good, and it gets worse: the new PM Liz Truss wants to ban solar panels on farms, Conservatives clearly don’t understand how the world works.

The good news comes from research proving that agrivoltaics (agriculture + solar voltaic panels) are a boon to farmers. Solar panels on farms are good for revenue for farms, renewable energy, and the very crops farms are growing. Yes, solar panels on farm increase crop production!

One study found certain peppers will have three times the production,” said Bousselot. “That’s a shocking number.”

As global temperatures rise, the panels can also help to conserve dwindling freshwater supplies by reducing evaporation from both plants and soil.

What evaporation does occur underneath the panels has the added benefit of cooling the PVs and boosting their electricity production, according to Randle-Boggis, a research associate at the University of Sheffield.

Renewable Energy Unscathed by Hurricane

Surviving ever-worsening climate change enhanced storms is a clear benefit of renewable energy, and people in Florida are taking note. Hurricane Ian just swept through the state leaving thousands with electricity. A town in the hardest hit area of the state was still running fine though, thanks to solar panels. The community invested heavily in renewable energy systems (and increased electrification) and weather the hurricane just fine. The savings from renewable aren’t just monetary.

“We have proof of the case now because [the hurricane] came right over us,” Nancy Chorpenning, a 68-year-old Babcock Ranch resident, told CNN. “We have water, electricity, internet — and we may be the only people in Southwest Florida who are that fortunate.”

The ranch broke ground in 2015 with the construction of the solar array — which was built and is run by Florida Power and Light — and its first residents moved into the town in 2018. Since then, the array has doubled in size and thousands of people have made Babcock their home.

“It’s a great case study to show that it can be done right, if you build in the right place and do it the right way,” said Lisa Hall, a spokesperson for Kitson, who also lives in Babcock Ranch.
