It will probably be a month or so before the house reaches the true neutral energy cost. However I had the first free tank of hot water today. About 4kWh of excess #solargeneration went into the hot water and almost 6kWh to the grid.

Fun fact: Dubioza Kolektiv’s entire discography is available on Bandcamp for a “name your price” download, yes, even for $0 DRM-Free.
"What do you get when you mix infectious positivity and raw energy with ska, punk, reggae, electronic and hip-hop influences? You get Dubioza Kolektiv, a must see live act praised by audiences all around the world. They toured and continue touring tirelessly, leaving a trail of adrenaline and good vibes behind."

No shortage of public EV charging posts in Utrecht ;)
The green ones have free spots (the number shows how many there are under one dot on the map), the blue don't.
These are the ones I can use with my E-Flux card. Prices vary quite a lot, but you can find them by clicking https://dashboard.e-flux.io/my-map

arXiv:2602.13743v1 Announce Type: new
Abstract: Compact Free-Electron Lasers (FELs) offering broad, continuous spectral tunability are traditionally constrained by fixed-parameter magnetic structures and the necessity for high-energy electron beams. High-gain Harmonic Lasing (HL) has long been proposed as a solution to overcome these limitations; however, a robust experimental verification of this principle has remained absent. Here, we report the first experimental demonstration of high-gain HL. By employing a frequency-tunable electron beam density modulation to dominate the fundamental instability, we achieved sustained FEL amplification at the 3rd and 5th harmonics of the wiggler. The HL mode generated output power comparable to conventional fundamental operation with enhanced stability and narrower spectral bandwidth. Notably, we demonstrate that HL extends the spectral coverage by a factor of two under fixed facility constraints, achieving pulse energies up to 540 {\mu}J. These results establish high-gain HL as a versatile mechanism for advancing compact, wavelength-flexible FEL facilities.

Oklahoma is crashing the green hydrogen party with some serious innovation.
Startup Tobe Energy just landed $1.8M for their membrane-free electrolysis system that could slash production costs by up to 75%. Their secret? LED technology that simplifies the process and cuts waste heat.
With strong renewables and business-friendly policies, Oklahoma is positioning itself as a major player in the energy transition.

Reform have written to me. Wow, what a push poll. “Rising crime”, “mass immigration” (not devolved), but no mention of transport, let alone the environment (unless that’s what they mean by high energy prices).
Also, why only one set of choices for who I’m voting for? Have Reform forgotten that in a Scottish election you have two votes (constituency and list)?

Sweden just invested $12M in solar cells that work indoors.
Exeger's Powerfoyle technology could eliminate disposable batteries in everyday electronics by harvesting energy from indoor and outdoor light. The flexible solar cells reduce dependence on critical raw materials while offering high conductivity.
This funding will help scale production and move us closer to a battery-free future for consumer devices.
