Vox: Why kids don’t get as cold as adults

Makes sense, but growing up in Houston I liked it hot no matter what I was doing, even in school. Now that I’ve been in far N. California for 25+ years I’m ruined and 95 is oppressive even on the river. NorCal made me soft…our summers are usually 75-80 highs.

Because playing in a river or on a beach in intense heat is great... painting a fence or working on your car in same heat is shit:)

How A Brick & Rock Battery Is Changing Energy Storage

spawnflagger says...

yeah, since efficiency is usually a measure of how much energy is lost to heat, should be 0% vs 100%... but, marketing.

I also doubt they are using aerogel or cryostats insulation to surround hot bricks. (or maybe that's why 1 container costs $9M?)

Matt (and team) from Undecided almost never approach their videos with a critical eye. Many startups' claims can be debunked with high school physics, but they just present everything as-is and with good production value. I consider their channel more entertainment than education, but still interesting to see some of the ideas out there.

Ok. I like the concept….thermal mass as short term heat storage/release is a well established science.

Sadly calling bullshit when they claim converting electricity to heat is 100% efficient. Nothing is 100% efficient.
They also claim 98% efficiency “pulling the heat back out”…unbelievably high.
Noticeably missing were heat loss rates, both for capture and storage over time…both expected to be extremely high at temperatures of 1500C.

The second system boasting 80% efficiency (but why burning wood?) is more realistic, but the only 3% heat loss per day at 500C temperatures claim is not. No insulation I’ve ever heard of is that efficient.

Recycling industrial manufacturing heat seems smart, but I think they need to be honest up front about the real world expectations and uses. If it could cut the energy needed to bake limestone or melt steel in half, that’s great…please don’t imply it could cut it by anything approaching 97%. That makes me not trust it at all.
