From gas filled solar tubes. I need to bring the temperature of the sand to around 50 degrees C.

That's why I wanted a sand battery. To store captured energy for days like today and yesterday.

It's not just the label. In case the police or the insurance company asks you for a certificate of conformity, who is going to supply it if you make your own label?

I intend to use gas filled solar tubes in my garden to heat the sand, so it's entirely passive except for the pumps

I am mulling over using a sand battery to store heat during the day and use it for underfloor heating at night. Would that make economic sense?

If you have not derestricted your bike, your motor will deliver less than 250W continuous on a flat road and on throttle to maintain 25kph. The problem arises only when people derestrict their bikes.

I think it would. The current SMR plan from RR does not mention cooperation with China but we know by experience that it would be inevitable. There are too many competitors vying for contracts, cooperation with other countries or companies is necessary. China has the production capability in...

China has production cost of its nuclear power at around 5.5 us cents per KWH. SMRs are supposed to keep production cost low so I have high hope that it'll be true.

SMR is the general concept for installation, maintenance and decommissioning. SMRs can bring production cost down to the level of wind and solar. I am pretty sure that companies like RR can bring a few good recipes to the party.

Tesla makes their cars in China and soon in Mexico and India, RR makes money on servicing so why not manufacture in China?

RR can do design work and get their reactors built in China.

That reminds me of what happens on amazon and eBay when suppliers run out of stock. They change the prices to something silly.

the world's first SMR has been installed last August. It is planned to supply 1 billion kWH a year, enough electricity for about 500,000 inhabitants of China's largest island. It saves about 800,000 tonnes of CO2 a year. That explains why RR shares went up so quickly since.

Merry Christmas and Happy New Year. With best wishes from all of us at Woosh.

Try the locksmiths. Battery locks won't resist their tools for more than 15 seconds. They can cut new keys for you too

You can see why I don't want to sell components on their own due to their potential misuse. I am often asked: can you sell me a 48v 10ah bag battery for my BBSHD or for my 1000W front hub kit? can you sell me an Aikema 85SX for my 48V KT system? or a TSDZ2B to run at 52V. The 13S2P bag battery...

They should specify also the controllers.

it's down to performance. Even modestly priced EV models have excellent acceleration. Fast acceleration leads to more accidents.

I think it's more about air quality.

When I learned for the first time that the tests were rubber-stamped, I was flabbergasted like most members. the motor rating needs to be understood in the context of actual use. the tests are done when you are not climbing a hill or having a gale blowing in your face. They can be made on real...
